composer-cli
============
:Authors:
Brian C. Lane <bcl@redhat.com>
``composer-cli`` is used to interact with the ``lorax-composer`` API server, managing blueprints, exploring available packages, and building new images.
It requires `lorax-composer <lorax-composer.html>`_ to be installed on the
local system, and the user running it needs to be a member of the ``weldr``
group. They do not need to be root, but all of the `security precautions
<lorax-composer.html#security>`_ apply.
composer-cli cmdline arguments
------------------------------
.. argparse::
:ref: composer.cli.cmdline.composer_cli_parser
:prog: composer-cli
Edit a Blueprint
----------------
Start out by listing the available blueprints using ``composer-cli blueprints
list``, pick one and save it to the local directory by running ``composer-cli
blueprints save http-server``. If there are no blueprints available you can
copy one of the examples `from the test suite
<https://github.com/weldr/lorax/tree/master/tests/pylorax/blueprints/>`_.
Edit the file (it will be saved with a .toml extension) and change the
description, add a package or module to it. Send it back to the server by
running ``composer-cli blueprints push http-server.toml``. You can verify that it was
saved by viewing the changelog - ``composer-cli blueprints changes http-server``.
Build an image
----------------
Build a ``qcow2`` disk image from this blueprint by running ``composer-cli
compose start http-server qcow2``. It will print a UUID that you can use to
keep track of the build. You can also cancel the build if needed.
The available types of images is displayed by ``composer-cli compose types``.
Currently this consists of: alibaba, ami, ext4-filesystem, google, live-iso,
openstack, partitioned-disk, qcow2, tar, vhd, vmdk
Monitor the build status
------------------------
Monitor it using ``composer-cli compose status``, which will show the status of
all the builds on the system. You can view the end of the anaconda build logs
once it is in the ``RUNNING`` state using ``composer-cli compose log UUID``
where UUID is the UUID returned by the start command.
Once the build is in the ``FINISHED`` state you can download the image.
Download the image
------------------
Downloading the final image is done with ``composer-cli compose image UUID`` and it will
save the qcow2 image as ``UUID-disk.qcow2`` which you can then use to boot a VM like this::
qemu-kvm --name test-image -m 1024 -hda ./UUID-disk.qcow2

Introduction to Lorax
=====================
I am the Lorax. I speak for the trees [and images].
Lorax is used to build the Anaconda Installer boot.iso, it consists of a
library, pylorax, a set of templates, and the lorax script. Its operation
is driven by a customized set of Mako templates that lists the packages
to be installed, steps to execute to remove unneeded files, and creation
of the iso for all of the supported architectures.
Before Lorax
============
Tree building tools such as pungi and revisor rely on 'buildinstall' in
anaconda/scripts/ to produce the boot images and other such control files
in the final tree. The existing buildinstall scripts written in a mix of
bash and Python are unmaintainable. Lorax is an attempt to replace them
with something more flexible.
EXISTING WORKFLOW:
pungi and other tools call scripts/buildinstall, which in turn call other
scripts to do the image building and data generation. Here's how it
currently looks:
-> buildinstall
* process command line options
* write temporary yum.conf to point to correct repo
* find anaconda release RPM
* unpack RPM, pull in those versions of upd-instroot, mk-images,
maketreeinfo.py, makestamp.py, and buildinstall
-> call upd-instroot
-> call maketreeinfo.py
-> call mk-images (which figures out which mk-images.ARCH to call)
-> call makestamp.py
* clean up
PROBLEMS:
The existing workflow presents some problems with maintaining the scripts.
First, almost all knowledge of what goes in to the stage 1 and stage 2
images lives in upd-instroot. The mk-images* scripts copy things from the
root created by upd-instroot in order to build the stage 1 image, though
it's not completely clear from reading the scripts.
NEW IDEAS:
Create a new central driver with all information living in Python modules.
Configuration files will provide the knowledge previously contained in the
upd-instroot and mk-images* scripts.

livemedia-creator
=================
:Authors:
Brian C. Lane <bcl@redhat.com>
livemedia-creator uses `Anaconda <https://github.com/rhinstaller/anaconda>`_,
`kickstart <https://github.com/rhinstaller/pykickstart>`_ and `Lorax
<https://github.com/rhinstaller/lorax>`_ to create bootable media that use the
same install path as a normal system installation. It can be used to make live
isos, bootable (partitioned) disk images, tarfiles, and filesystem images for
use with virtualization and container solutions like libvirt, docker, and
OpenStack.
The general idea is to use qemu with kickstart and an Anaconda boot.iso to
install into a disk image and then use the disk image to create the bootable
media.
livemedia-creator --help will describe all of the options available. At the
minimum you need:
``--make-iso`` to create a final bootable .iso or one of the other ``--make-*`` options.
``--iso`` to specify the Anaconda install media to use with qemu.
``--ks`` to select the kickstart file describing what to install.
To use livemedia-creator with virtualization you will need to have qemu-kvm installed.
If you are going to be using Anaconda directly, with ``--no-virt`` mode, make sure
you have the anaconda-tui package installed.
Conventions used in this document:
``lmc`` is an abbreviation for livemedia-creator.
``builder`` is the system where livemedia-creator is being run
``image`` is the disk image being created by running livemedia-creator
livemedia-creator cmdline arguments
-----------------------------------
.. argparse::
:ref: pylorax.cmdline.lmc_parser
:prog: livemedia-creator
--macboot : @replace
Make the iso bootable on UEFI based Mac systems
Default: True
--nomacboot : @replace
Do not create a Mac bootable iso
Default: False
Quickstart
----------
Run this to create a bootable live iso::
sudo livemedia-creator --make-iso \
--iso=/extra/iso/boot.iso --ks=./docs/rhel-livemedia.ks
You can run it directly from the lorax git repo like this::
sudo PATH=./src/sbin/:$PATH PYTHONPATH=./src/ ./src/sbin/livemedia-creator \
--make-iso --iso=/extra/iso/boot.iso \
--ks=./docs/rhel-livemedia.ks --lorax-templates=./share/
You can observe the installation using vnc. The logs will show what port was
chosen, or you can use a specific port by passing it. eg. ``--vnc vnc:127.0.0.1:5``
This is usually a good idea when testing changes to the kickstart. lmc tries
to monitor the logs for fatal errors, but may not catch everything.
How ISO creation works
----------------------
There are 2 stages, the install stage which produces a disk or filesystem image
as its output, and the boot media creation which uses the image as its input.
Normally you would run both stages, but it is possible to stop after the
install stage, by using ``--image-only``, or to skip the install stage and use
a previously created disk image by passing ``--disk-image`` or ``--fs-image``
When creating an iso qemu boots using the passed Anaconda installer iso
and installs the system based on the kickstart. The ``%post`` section of the
kickstart is used to customize the installed system in the same way that
current spin-kickstarts do.
livemedia-creator monitors the install process for problems by watching the
install logs. They are written to the current directory or to the base
directory specified by the --logfile command. You can also monitor the install
by using a vnc client. This is recommended when first modifying a kickstart,
since there are still places where Anaconda may get stuck without the log
monitor catching it.
The output from this process is a partitioned disk image. kpartx can be used
to mount and examine it when there is a problem with the install. It can also
be booted using kvm.
When creating an iso the disk image's / partition is copied into a formatted
filesystem image which is then used as the input to lorax for creation of the
final media.
The final image is created by lorax, using the templates in /usr/share/lorax/live/
or the live directory below the directory specified by ``--lorax-templates``. The
templates are written using the Mako template system with some extra commands
added by lorax.
.. note::
The output from --make-iso includes the artifacts used to create the boot.iso;
the kernel, initrd, the squashfs filesystem, etc. If you only want the
boot.iso you can pass ``--iso-only`` and the other files will be removed. You
can also name the iso by using ``--iso-name my-live.iso``.
Kickstarts
----------
The docs/ directory includes several example kickstarts, one to create a live
desktop iso using GNOME, and another to create a minimal disk image. When
creating your own kickstarts you should start with the minimal example, it
includes several needed packages that are not always included by dependencies.
Or you can use existing spin kickstarts to create live media with a few
changes. Here are the steps I used to convert the Fedora XFCE spin.
1. Flatten the xfce kickstart using ksflatten
2. Add zerombr so you don't get the disk init dialog
3. Add clearpart --all
4. Add swap partition
5. bootloader target
6. Add shutdown to the kickstart
7. Add network --bootproto=dhcp --activate to activate the network
This works for F16 builds but for F15 and before you need to pass
something on the cmdline that activate the network, like sshd:
``livemedia-creator --kernel-args="sshd"``
8. Add a root password::
rootpw rootme
network --bootproto=dhcp --activate
zerombr
clearpart --all
bootloader --location=mbr
part swap --size=512
shutdown
9. In the livesys script section of the %post remove the root password. This
really depends on how the spin wants to work. You could add the live user
that you create to the %wheel group so that sudo works if you wanted to.
``passwd -d root > /dev/null``
10. Remove /etc/fstab in %post, dracut handles mounting the rootfs
``cat /dev/null > /dev/fstab``
Do this only for live iso's, the filesystem will be mounted read only if
there is no /etc/fstab
11. Don't delete initramfs files from /boot in %post
12. When creating live iso's you need to have, at least, these packages in the %package section::
dracut-config-generic
dracut-live
-dracut-config-rescue
grub-efi
memtest86+
syslinux
One drawback to using qemu is that it pulls the packages from the repo each
time you run it. To speed things up you either need a local mirror of the
packages, or you can use a caching proxy. When using a proxy you pass it to
livemedia-creator like this:
``--proxy=http://proxy.yourdomain.com:3128``
You also need to use a specific mirror instead of mirrormanager so that the
packages will get cached, so your kickstart url would look like:
``url --url="http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/x86_64/os/"``
You can also add an update repo, but don't name it updates. Add --proxy to it
as well.
Anaconda image install (no-virt)
--------------------------------
You can create images without using qemu by passing ``--no-virt`` on the
cmdline. This will use Anaconda's directory install feature to handle the
install. There are a couple of things to keep in mind when doing this:
1. It will be most reliable when building images for the same release that the
host is running. Because Anaconda has expectations about the system it is
running under you may encounter strange bugs if you try to build newer or
older releases.
2. It may totally trash your host. So far I haven't had this happen, but the
possibility exists that a bug in Anaconda could result in it operating on
real devices. I recommend running it in a virt or on a system that you can
afford to lose all data from.
The logs from anaconda will be placed in an ./anaconda/ directory in either
the current directory or in the directory used for --logfile
Example cmdline:
``sudo livemedia-creator --make-iso --no-virt --ks=./rhel-livemedia.ks``
.. note::
Using no-virt to create a partitioned disk image (eg. --make-disk or
--make-vagrant) will only create disks usable on the host platform (BIOS
or UEFI). You can create BIOS partitioned disk images on UEFI by using
virt.
.. note::
As of version 30.7 SELinux can be set to Enforcing. The current state is
logged for debugging purposes and if there are SELinux denials they should
be reported as a bug.
AMI Images
----------
Amazon EC2 images can be created by using the --make-ami switch and an appropriate
kickstart file. All of the work to customize the image is handled by the kickstart.
The example currently included was modified from the cloud-kickstarts version so
that it would work with livemedia-creator.
Example cmdline:
``sudo livemedia-creator --make-ami --iso=/path/to/boot.iso --ks=./docs/rhel-livemedia-ec2.ks``
This will produce an ami-root.img file in the working directory.
At this time I have not tested the image with EC2. Feedback would be welcome.
Appliance Creation
------------------
livemedia-creator can now replace appliance-tools by using the --make-appliance
switch. This will create the partitioned disk image and an XML file that can be
used with virt-image to setup a virtual system.
The XML is generated using the Mako template from
/usr/share/lorax/appliance/libvirt.xml You can use a different template by
passing ``--app-template <template path>``
Documentation on the Mako template system can be found at the `Mako site
<http://docs.makotemplates.org/en/latest/index.html>`_
The name of the final output XML is appliance.xml, this can be changed with
``--app-file <file path>``
The following variables are passed to the template:
``disks``
A list of disk_info about each disk.
Each entry has the following attributes:
``name``
base name of the disk image file
``format``
"raw"
``checksum_type``
"sha256"
``checksum``
sha256 checksum of the disk image
``name``
Name of appliance, from --app-name argument
``arch``
Architecture
``memory``
Memory in KB (from ``--ram``)
``vcpus``
from ``--vcpus``
``networks``
list of networks from the kickstart or []
``title``
from ``--title``
``project``
from ``--project``
``releasever``
from ``--releasever``
The created image can be imported into libvirt using:
``virt-image appliance.xml``
You can also create qcow2 appliance images using ``--image-type=qcow2``, for example::
sudo livemedia-creator --make-appliance --iso=/path/to/boot.iso --ks=./docs/rhel-minimal.ks \
--image-type=qcow2 --app-file=minimal-test.xml --image-name=minimal-test.img
Filesystem Image Creation
-------------------------
livemedia-creator can be used to create un-partitined filesystem images using
the ``--make-fsimage`` option. As of version 21.8 this works with both qemu and
no-virt modes of operation. Previously it was only available with no-virt.
Kickstarts should have a single / partition with no extra mountpoints.
``livemedia-creator --make-fsimage --iso=/path/to/boot.iso --ks=./docs/rhel-minimal.ks``
You can name the output image with ``--image-name`` and set a label on the filesystem with ``--fs-label``
TAR File Creation
-----------------
The ``--make-tar`` command can be used to create a tar of the root filesystem. By
default it is compressed using xz, but this can be changed using the
``--compression`` and ``--compress-arg`` options. This option works with both virt and
no-virt install methods.
As with ``--make-fsimage`` the kickstart should be limited to a single / partition.
For example::
livemedia-creator --make-tar --iso=/path/to/boot.iso --ks=./docs/rhel-minimal.ks \
--image-name=rhel-root.tar.xz
Live Image for PXE Boot
-----------------------
The ``--make-pxe-live`` command will produce squashfs image containing live root
filesystem that can be used for pxe boot. Directory with results will contain
the live image, kernel image, initrd image and template of pxe configuration
for the images.
Atomic Live Image for PXE Boot
------------------------------
The ``--make-ostree-live`` command will produce the same result as ``--make-pxe-live``
for installations of Atomic Host. Example kickstart for such an installation
using Atomic installer iso with local repo included in the image can be found
in docs/rhel-atomic-pxe-live.ks.
The PXE images can also be created with ``--no-virt`` by using the example
kickstart in docs/rhel-atomic-pxe-live-novirt.ks. This also works inside the
mock environment.
Using Mock and --no-virt to Create Images
-----------------------------------------
As of lorax version 22.2 you can use livemedia-creator and anaconda version
22.15 inside of a mock chroot with --make-iso and --make-fsimage.
.. note::
As of mock 1.3.4 you need to use ``--old-chroot`` with mock. Mock now defaults to using systemd-nspawn
which cannot create the needed loop device nodes. Passing ``--old-chroot`` will use the old system
where ``/dev/loop*`` is setup for you.
On the host system:
1. yum install -y mock
2. Add a user to the mock group to use for running mock. eg. builder
3. Create a new /etc/mock/ config file based on the rawhide one, or modify the
existing one so that the following options are setup::
config_opts['chroot_setup_cmd'] = 'install @buildsys-build anaconda-tui lorax'
# build results go into /home/builder/results/
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/home/builder/results','/results/'))
If you are creating images for a branched release of Fedora you should also enable
the updates-testing repository so that you get the latest builds in your mock chroot.
The following steps are run as the builder user who is a member of the mock
group.
4. Make a directory for results matching the bind mount above
``mkdir ~/results/``
5. Copy the example kickstarts
``cp /usr/share/docs/lorax/*ks .``
6. Make sure tar and dracut-network are in the %packages section and that the
``url points to the correct repo``
7. Init the mock
``mock -r rhel-8-x86_64 --old-chroot --init``
8. Copy the kickstart inside the mock
``mock -r rhel-8-x86_64 --old-chroot --copyin ./rhel-minimal.ks /root/``
9. Make a minimal iso::
mock -r rhel-8-x86_64 --old-chroot --chroot -- livemedia-creator --no-virt \
--resultdir=/results/try-1 --logfile=/results/logs/try-1/try-1.log \
--make-iso --ks /root/rhel-minimal.ks
Results will be in ./results/try-1 and logs under /results/logs/try-1/
including anaconda logs and livemedia-creator logs. The new iso will be
located at ~/results/try-1/images/boot.iso, and the ~/results/try-1/
directory tree will also contain the vmlinuz, initrd, etc.
Using Mock and qemu to Create Images
------------------------------------
Version 25.0 of livemedia-creator switches to using qemu for virtualization.
This allows creation of all image types, and use of the KVM on the host if
/dev/kvm is present in the mock environment.
On the host system:
1. yum install -y mock
2. Add a user to the mock group to use for running mock. eg. builder
3. Create a new /etc/mock/ config file based on the rawhide one, or modify the
existing one so that the following options are setup::
config_opts['chroot_setup_cmd'] = 'install @buildsys-build lorax qemu'
# build results go into /home/builder/results/
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/home/builder/results','/results/'))
If you are creating images for a branched release of Fedora you should also enable
the updates-testing repository so that you get the latest builds in your mock chroot.
The following steps are run as the builder user who is a member of the mock
group.
4. Make a directory for results matching the bind mount above
``mkdir ~/results/``
5. Copy the example kickstarts
``cp /usr/share/docs/lorax/*ks .``
6. Make sure tar and dracut-network are in the %packages section and that the
``url points to the correct repo``
7. Init the mock
``mock -r rhel-8-x86_64 --old-chroot --init``
8. Copy the kickstart inside the mock
``mock -r rhel-8-x86_64 --old-chroot --copyin ./rhel-minimal.ks /root/``
9. Copy the Anaconda boot.iso inside the mock
``mock -r rhel-8-x86_64 --old-chroot --copyin ./boot.iso /root/``
10. Make a minimal iso::
mock -r rhel-8-x86_64 --old-chroot --chroot -- livemedia-creator \
--resultdir=/results/try-1 --logfile=/results/logs/try-1/try-1.log \
--make-iso --ks /root/rhel-minimal.ks --iso /root/boot.iso
Results will be in ./results/try-1 and logs under /results/logs/try-1/
including anaconda logs and livemedia-creator logs. The new iso will be
located at ~/results/try-1/images/boot.iso, and the ~/results/try-1/
directory tree will also contain the vmlinuz, initrd, etc.
This will run qemu without kvm support, which is going to be very slow. You can
add ``mknod /dev/kvm c 10 232;`` to create the device node before running lmc.
OpenStack Image Creation
------------------------
OpenStack supports partitioned disk images so ``--make-disk`` can be used to
create images for importing into glance, OpenStack's image storage component.
You need to have access to an OpenStack provider that allows image uploads, or
setup your own using the instructions from the `RDO Project
<https://www.rdoproject.org/Quickstart>`_.
The example kickstart, rhel-openstack.ks, is only slightly different than the
rhel-minimal.ks one. It adds the cloud-init and cloud-utils-growpart
packages. OpenStack supports setting up the image using cloud-init, and
cloud-utils-growpart will grow the image to fit the instance's disk size.
Create a qcow2 image using the kickstart like this:
``sudo livemedia-creator --make-disk --iso=/path/to/boot.iso --ks=/path/to/rhel-openstack.ks --image-type=qcow2``
.. note::
On the RHEL7 version of lmc ``--image-type`` isn't supported. You can only create a bare partitioned disk image.
Import the resulting disk image into the OpenStack system, either via the web UI, or glance on the cmdline::
glance image-create --name "rhel-openstack" --is-public true --disk-format qcow2 \
--container-format bare --file ./rhel-openstack.qcow2
If qcow2 wasn't used then ``--disk-format`` should be set to raw.
Container Image Creation
------------------------
Use lmc to create a tarfile as described in the `TAR File Creation`_ section, but substitute the
rhel-container.ks example kickstart which removes the requirement for core files and the kernel.
You can then import the tarfile into podman or docker like this:
``podman import /var/tmp/root.tar.xz rhel-root``
And then run bash inside of it:
``podman run -i -t rhel-root /bin/bash``
Open Container Initiative Image Creation
----------------------------------------
The OCI is a new specification that is still being worked on. You can read more about it at
`the Open Container Initiative website <https://www.opencontainers.org/>`_. You can create
OCI images using the following command::
sudo livemedia-creator --make-oci --oci-config /path/to/config.json --oci-runtime /path/to/runtime.json \
--iso=/path/to/boot.iso --ks=/path/to/rhel-minimal.ks
You must provide the config.json and runtime.json files to be included in the bundle,
their specifications can be found `on the OCI github project <https://github.com/opencontainers/specs>`_
output will be in the results directory with a default name of bundle.tar.xz
This will work with ``--no-virt`` and inside a mock since it doesn't use any
partitioned disk images.
Vagrant Image Creation
----------------------
`Vagrant <https://www.vagrantup.com/>`_ images can be created using the following command::
sudo livemedia-creator --make-vagrant --vagrant-metadata /path/to/metadata.json \
--iso=/path/to/boot.iso --ks=/path/to/rhel-vagrant.ks
The image created is a `vagrant-libvirt
<https://github.com/pradels/vagrant-libvirt>`_ provider image and needs to have
vagrant setup with libvirt before you can use it.
The ``--vagrant-metadata`` file is optional, it will create a minimal one by
default, and if one is passed it will make sure the disk size is setup
correctly. If you pass a ``--vagrant-vagrantfile`` it will be included in the
image verbatim. By default no vagrantfile is created.
There is an example Vagrant kickstart file in the docs directory that sets up
the vagrant user with the default insecure SSH pubkey and a few useful
utilities.
This also works with ``--no-virt``, but will not work inside a mock due to its
use of partitioned disk images and qcow2.
Creating UEFI disk images with virt
-----------------------------------
Partitioned disk images can only be created for the same platform as the host system (BIOS or
UEFI). You can use virt to create BIOS images on UEFI systems, and it is also possible
to create UEFI images on BIOS systems using OVMF firmware and qemu.
Install the lorax-lmc-virt package, this will install qemu and the OVMF
firmware files.
Now you can run livemedia-creator with ``--virt-uefi`` to boot and install using UEFI::
sudo livemedia-creator --make-disk --virt-uefi --iso=/path/to/boot.iso \
--ks=/path/to/rhel-minimal.ks
Make sure that the kickstart you are using creates a /boot/efi partition by including this::
part /boot/efi --fstype="efi" --size=500
Or use ``reqpart`` in the kickstart and Anaconda will create the required partitions.
.. note::
The --virt-uefi method is currently only supported on the x86_64 architecture.
Debugging problems
------------------
Sometimes an installation will get stuck. When using qemu the logs will
be written to ./virt-install.log and most of the time any problems that happen
will be near the end of the file. lmc tries to detect common errors and will
cancel the installation when they happen. But not everything can be caught.
When creating a new kickstart it is helpful to use vnc so that you can monitor
the installation as it happens, and if it gets stuck without lmc detecting the
problem you can switch to tty1 and examine the system directly.
If it does get stuck the best way to cancel is to use kill -9 on the qemu pid,
lmc will detect that the process died and cleanup.
If lmc didn't handle the cleanup for some reason you can do this:
1. ``sudo umount /tmp/lmc-XXXX`` to unmount the iso from its mountpoint.
2. ``sudo rm -rf /tmp/lmc-XXXX``
3. ``sudo rm /var/tmp/lmc-disk-XXXXX`` to remove the disk image.
Note that lmc uses the lmc- prefix for all of its temporary files and
directories to make it easier to find and clean up leftovers.
The logs from the qemu run are stored in virt-install.log, logs from
livemedia-creator are in livemedia.log and program.log
You can add ``--image-only`` to skip the .iso creation and examine the resulting
disk image. Or you can pass ``--keep-image`` to keep it around after the iso has
been created.
Cleaning up aborted ``--no-virt`` installs can sometimes be accomplished by
running the ``anaconda-cleanup`` script. As of Fedora 18 anaconda is
multi-threaded and it can sometimes become stuck and refuse to exit. When this
happens you can usually clean up by first killing the anaconda process then
running ``anaconda-cleanup``.
Hacking

Development on this will take place as part of the lorax project, and on the
anaconda-devel-list mailing list, and `on github <https://github.com/rhinstaller/lorax>`_
Feedback, enhancements and bugs are welcome. You can use `bugzilla

livemedia-creator
=================
:Authors:
Brian C. Lane <bcl@redhat.com>
livemedia-creator uses `Anaconda <https://github.com/rhinstaller/anaconda>`_,
`kickstart <https://github.com/rhinstaller/pykickstart>`_ and `Lorax
<https://github.com/rhinstaller/lorax>`_ to create bootable media that use the
same install path as a normal system installation. It can be used to make live
isos, bootable (partitioned) disk images, tarfiles, and filesystem images for
use with virtualization and container solutions like libvirt, docker, and
OpenStack.
The general idea is to use qemu with kickstart and an Anaconda boot.iso to
install into a disk image and then use the disk image to create the bootable
media.
livemedia-creator --help will describe all of the options available. At the
minimum you need:
``--make-iso`` to create a final bootable .iso or one of the other ``--make-*`` options.
``--iso`` to specify the Anaconda install media to use with qemu.
``--ks`` to select the kickstart file describing what to install.
To use livemedia-creator with virtualization you will need to have qemu installed.
If you are going to be using Anaconda directly, with ``--no-virt`` mode, make sure
you have the anaconda-tui package installed.
Conventions used in this document:
``lmc`` is an abbreviation for livemedia-creator.
``builder`` is the system where livemedia-creator is being run
``image`` is the disk image being created by running livemedia-creator
livemedia-creator cmdline arguments
-----------------------------------
.. argparse::
:ref: pylorax.cmdline.lmc_parser
:prog: livemedia-creator
Quickstart
----------
Run this to create a bootable live iso::
sudo livemedia-creator --make-iso \
--iso=/extra/iso/boot.iso --ks=./docs/fedora-livemedia.ks
You can run it directly from the lorax git repo like this::
sudo PATH=./src/sbin/:$PATH PYTHONPATH=./src/ ./src/sbin/livemedia-creator \
--make-iso --iso=/extra/iso/boot.iso \
--ks=./docs/fedora-livemedia.ks --lorax-templates=./share/
You can observe the installation using vnc. The logs will show what port was
chosen, or you can use a specific port by passing it. eg. ``--vnc vnc:127.0.0.1:5``
This is usually a good idea when testing changes to the kickstart. lmc tries
to monitor the logs for fatal errors, but may not catch everything.
How ISO creation works
----------------------
There are 2 stages, the install stage which produces a disk or filesystem image
as its output, and the boot media creation which uses the image as its input.
Normally you would run both stages, but it is possible to stop after the
install stage, by using ``--image-only``, or to skip the install stage and use
a previously created disk image by passing ``--disk-image`` or ``--fs-image``
When creating an iso qemu boots using the passed Anaconda installer iso
and installs the system based on the kickstart. The ``%post`` section of the
kickstart is used to customize the installed system in the same way that
current spin-kickstarts do.
livemedia-creator monitors the install process for problems by watching the
install logs. They are written to the current directory or to the base
directory specified by the --logfile command. You can also monitor the install
by using a vnc client. This is recommended when first modifying a kickstart,
since there are still places where Anaconda may get stuck without the log
monitor catching it.
The output from this process is a partitioned disk image. kpartx can be used
to mount and examine it when there is a problem with the install. It can also
be booted using kvm.
When creating an iso the disk image's / partition is copied into a formatted
filesystem image which is then used as the input to lorax for creation of the
final media.
The final image is created by lorax, using the templates in /usr/share/lorax/live/
or the live directory below the directory specified by ``--lorax-templates``. The
templates are written using the Mako template system with some extra commands
added by lorax.
.. note::
The output from --make-iso includes the artifacts used to create the boot.iso;
the kernel, initrd, the squashfs filesystem, etc. If you only want the
boot.iso you can pass ``--iso-only`` and the other files will be removed. You
can also name the iso by using ``--iso-name my-live.iso``.
Kickstarts
----------
The docs/ directory includes several example kickstarts, one to create a live
desktop iso using GNOME, and another to create a minimal disk image. When
creating your own kickstarts you should start with the minimal example, it
includes several needed packages that are not always included by dependencies.
Or you can use existing spin kickstarts to create live media with a few
changes. Here are the steps I used to convert the Fedora XFCE spin.
1. Flatten the xfce kickstart using ksflatten
2. Add zerombr so you don't get the disk init dialog
3. Add clearpart --all
4. Add swap partition
5. bootloader target
6. Add shutdown to the kickstart
7. Add network --bootproto=dhcp --activate to activate the network
This works for F16 builds but for F15 and before you need to pass
something on the cmdline that activate the network, like sshd:
``livemedia-creator --kernel-args="sshd"``
8. Add a root password::
rootpw rootme
network --bootproto=dhcp --activate
zerombr
clearpart --all
bootloader --location=mbr
part swap --size=512
shutdown
9. In the livesys script section of the %post remove the root password. This
really depends on how the spin wants to work. You could add the live user
that you create to the %wheel group so that sudo works if you wanted to.
``passwd -d root > /dev/null``
10. Remove /etc/fstab in %post, dracut handles mounting the rootfs
``cat /dev/null > /dev/fstab``
Do this only for live iso's, the filesystem will be mounted read only if
there is no /etc/fstab
11. Don't delete initramfs files from /boot in %post
12. When creating live iso's you need to have, at least, these packages in the %package section::
dracut-config-generic
dracut-live
-dracut-config-rescue
grub-efi
memtest86+
syslinux
One drawback to using qemu is that it pulls the packages from the repo each
time you run it. To speed things up you either need a local mirror of the
packages, or you can use a caching proxy. When using a proxy you pass it to
livemedia-creator like this:
``--proxy=http://proxy.yourdomain.com:3128``
You also need to use a specific mirror instead of mirrormanager so that the
packages will get cached, so your kickstart url would look like:
``url --url="http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/x86_64/os/"``
You can also add an update repo, but don't name it updates. Add --proxy to it
as well.
Anaconda image install (no-virt)
--------------------------------
You can create images without using qemu by passing ``--no-virt`` on the
cmdline. This will use Anaconda's directory install feature to handle the
install. There are a couple of things to keep in mind when doing this:
1. It will be most reliable when building images for the same release that the
host is running. Because Anaconda has expectations about the system it is
running under you may encounter strange bugs if you try to build newer or
older releases.
2. Make sure selinux is set to permissive or disabled. It won't install
correctly with selinux set to enforcing yet.
3. It may totally trash your host. So far I haven't had this happen, but the
possibility exists that a bug in Anaconda could result in it operating on
real devices. I recommend running it in a virt or on a system that you can
afford to lose all data from.
The logs from anaconda will be placed in an ./anaconda/ directory in either
the current directory or in the directory used for --logfile
Example cmdline:
``sudo livemedia-creator --make-iso --no-virt --ks=./fedora-livemedia.ks``
.. note::
Using no-virt to create a partitioned disk image (eg. --make-disk or
--make-vagrant) will only create disks usable on the host platform (BIOS
or UEFI). You can create BIOS partitioned disk images on UEFI by using
virt.
AMI Images
----------
Amazon EC2 images can be created by using the --make-ami switch and an appropriate
kickstart file. All of the work to customize the image is handled by the kickstart.
The example currently included was modified from the cloud-kickstarts version so
that it would work with livemedia-creator.
Example cmdline:
``sudo livemedia-creator --make-ami --iso=/path/to/boot.iso --ks=./docs/fedora-livemedia-ec2.ks``
This will produce an ami-root.img file in the working directory.
At this time I have not tested the image with EC2. Feedback would be welcome.
Appliance Creation
------------------
livemedia-creator can now replace appliance-tools by using the --make-appliance
switch. This will create the partitioned disk image and an XML file that can be
used with virt-image to setup a virtual system.
The XML is generated using the Mako template from
/usr/share/lorax/appliance/libvirt.xml You can use a different template by
passing ``--app-template <template path>``
Documentation on the Mako template system can be found at the `Mako site
<http://docs.makotemplates.org/en/latest/index.html>`_
The name of the final output XML is appliance.xml, this can be changed with
``--app-file <file path>``
The following variables are passed to the template:
``disks``
A list of disk_info about each disk.
Each entry has the following attributes:
``name``
base name of the disk image file
``format``
"raw"
``checksum_type``
"sha256"
``checksum``
sha256 checksum of the disk image
``name``
Name of appliance, from --app-name argument
``arch``
Architecture
``memory``
Memory in KB (from ``--ram``)
``vcpus``
from ``--vcpus``
``networks``
list of networks from the kickstart or []
``title``
from ``--title``
``project``
from ``--project``
``releasever``
from ``--releasever``
The created image can be imported into libvirt using:
``virt-image appliance.xml``
You can also create qcow2 appliance images using ``--image-type=qcow2``, for example::
sudo livemedia-creator --make-appliance --iso=/path/to/boot.iso --ks=./docs/fedora-minimal.ks \
--image-type=qcow2 --app-file=minimal-test.xml --image-name=minimal-test.img
Filesystem Image Creation
-------------------------
livemedia-creator can be used to create un-partitined filesystem images using
the ``--make-fsimage`` option. As of version 21.8 this works with both qemu and
no-virt modes of operation. Previously it was only available with no-virt.
Kickstarts should have a single / partition with no extra mountpoints.
``livemedia-creator --make-fsimage --iso=/path/to/boot.iso --ks=./docs/fedora-minimal.ks``
You can name the output image with ``--image-name`` and set a label on the filesystem with ``--fs-label``
TAR File Creation
-----------------
The ``--make-tar`` command can be used to create a tar of the root filesystem. By
default it is compressed using xz, but this can be changed using the
``--compression`` and ``--compress-arg`` options. This option works with both virt and
no-virt install methods.
As with ``--make-fsimage`` the kickstart should be limited to a single / partition.
For example::
livemedia-creator --make-tar --iso=/path/to/boot.iso --ks=./docs/fedora-minimal.ks \
--image-name=fedora-root.tar.xz
Live Image for PXE Boot
-----------------------
The ``--make-pxe-live`` command will produce squashfs image containing live root
filesystem that can be used for pxe boot. Directory with results will contain
the live image, kernel image, initrd image and template of pxe configuration
for the images.
Atomic Live Image for PXE Boot
------------------------------
The ``--make-ostree-live`` command will produce the same result as ``--make-pxe-live``
for installations of Atomic Host. Example kickstart for such an installation
using Atomic installer iso with local repo included in the image can be found
in docs/rhel-atomic-pxe-live.ks.
The PXE images can also be created with ``--no-virt`` by using the example
kickstart in docs/fedora-atomic-pxe-live-novirt.ks. This also works inside the
mock environment.
Using Mock and --no-virt to Create Images
-----------------------------------------
As of lorax version 22.2 you can use livemedia-creator and anaconda version
22.15 inside of a mock chroot with --make-iso and --make-fsimage.
.. note::
As of mock 1.2.12 you no longer need to bind mount ``/dev/``, loop devices are setup
as part of the standard mock ``/dev/`` creation.
On the host system:
1. yum install -y mock
2. Add a user to the mock group to use for running mock. eg. builder
3. Create a new /etc/mock/ config file based on the rawhide one, or modify the
existing one so that the following options are setup::
config_opts['chroot_setup_cmd'] = 'install @buildsys-build anaconda-tui lorax'
# build results go into /home/builder/results/
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/home/builder/results','/results/'))
If you are creating images for a branched release of Fedora you should also enable
the updates-testing repository so that you get the latest builds in your mock chroot.
The following steps are run as the builder user who is a member of the mock
group.
4. Make a directory for results matching the bind mount above
``mkdir ~/results/``
5. Copy the example kickstarts
``cp /usr/share/docs/lorax/*ks .``
6. Make sure tar and dracut-network are in the %packages section and that the
``url points to the correct repo``
7. Init the mock
``mock -r fedora-rawhide-x86_64 --init``
8. Copy the kickstart inside the mock
``mock -r fedora-rawhide-x86_64 --copyin ./fedora-minimal.ks /root/``
9. Make a minimal iso::
mock -r fedora-rawhide-x86_64 --chroot -- livemedia-creator --no-virt \
--resultdir=/results/try-1 --logfile=/results/logs/try-1/try-1.log \
--make-iso --ks /root/fedora-minimal.ks
Results will be in ./results/try-1 and logs under /results/logs/try-1/
including anaconda logs and livemedia-creator logs. The new iso will be
located at ~/results/try-1/images/boot.iso, and the ~/results/try-1/
directory tree will also contain the vmlinuz, initrd, etc.
Using Mock and qemu to Create Images
------------------------------------
Version 25.0 of livemedia-creator switches to using qemu for virtualization.
This allows creation of all image types, and use of the KVM on the host if
/dev/kvm is present in the mock environment.
On the host system:
1. yum install -y mock
2. Add a user to the mock group to use for running mock. eg. builder
3. Create a new /etc/mock/ config file based on the rawhide one, or modify the
existing one so that the following options are setup::
config_opts['chroot_setup_cmd'] = 'install @buildsys-build lorax qemu'
# build results go into /home/builder/results/
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/home/builder/results','/results/'))
If you are creating images for a branched release of Fedora you should also enable
the updates-testing repository so that you get the latest builds in your mock chroot.
The following steps are run as the builder user who is a member of the mock
group.
4. Make a directory for results matching the bind mount above
``mkdir ~/results/``
5. Copy the example kickstarts
``cp /usr/share/docs/lorax/*ks .``
6. Make sure tar and dracut-network are in the %packages section and that the
``url points to the correct repo``
7. Init the mock
``mock -r fedora-rawhide-x86_64 --init``
8. Copy the kickstart inside the mock
``mock -r fedora-rawhide-x86_64 --copyin ./fedora-minimal.ks /root/``
9. Copy the Anaconda boot.iso inside the mock
``mock -r fedora-rawhide-x86_64 --copyin ./boot.iso /root/``
10. Make a minimal iso::
mock -r fedora-rawhide-x86_64 --chroot -- livemedia-creator \
--resultdir=/results/try-1 --logfile=/results/logs/try-1/try-1.log \
--make-iso --ks /root/fedora-minimal.ks --iso /root/boot.iso
Results will be in ./results/try-1 and logs under /results/logs/try-1/
including anaconda logs and livemedia-creator logs. The new iso will be
located at ~/results/try-1/images/boot.iso, and the ~/results/try-1/
directory tree will also contain the vmlinuz, initrd, etc.
This will run qemu without kvm support, which is going to be very slow. You can
add ``mknod /dev/kvm c 10 232;`` to create the device node before running lmc.
OpenStack Image Creation
------------------------
OpenStack supports partitioned disk images so ``--make-disk`` can be used to
create images for importing into glance, OpenStack's image storage component.
You need to have access to an OpenStack provider that allows image uploads, or
setup your own using the instructions from the `RDO Project
<https://www.rdoproject.org/Quickstart>`_.
The example kickstart, fedora-openstack.ks, is only slightly different than the
fedora-minimal.ks one. It adds the cloud-init and cloud-utils-growpart
packages. OpenStack supports setting up the image using cloud-init, and
cloud-utils-growpart will grow the image to fit the instance's disk size.
Create a qcow2 image using the kickstart like this:
``sudo livemedia-creator --make-disk --iso=/path/to/boot.iso --ks=/path/to/fedora-openstack.ks --image-type=qcow2``
.. note::
On the RHEL7 version of lmc ``--image-type`` isn't supported. You can only create a bare partitioned disk image.
Import the resulting disk image into the OpenStack system, either via the web UI, or glance on the cmdline::
glance image-create --name "fedora-openstack" --is-public true --disk-format qcow2 \
--container-format bare --file ./fedora-openstack.qcow2
If qcow2 wasn't used then ``--disk-format`` should be set to raw.
Docker Image Creation
---------------------
Use lmc to create a tarfile as described in the `TAR File Creation`_ section, but substitute the
fedora-docker.ks example kickstart which removes the requirement for core files and the kernel.
You can then import the tarfile into docker like this (as root):
``cat /var/tmp/fedora-root.tar.xz | docker import - fedora-root``
And then run bash inside of it:
``sudo docker run -i -t fedora-root /bin/bash``
Open Container Initiative Image Creation
----------------------------------------
The OCI is a new specification that is still being worked on. You can read more about it at
`the Open Container Initiative website <https://www.opencontainers.org/>`_. You can create
OCI images using the following command::
sudo livemedia-creator --make-oci --oci-config /path/to/config.json --oci-runtime /path/to/runtime.json \
--iso=/path/to/boot.iso --ks=/path/to/fedora-minimal.ks
You must provide the config.json and runtime.json files to be included in the bundle,
their specifications can be found `on the OCI github project <https://github.com/opencontainers/specs>`_
output will be in the results directory with a default name of bundle.tar.xz
This will work with ``--no-virt`` and inside a mock since it doesn't use any
partitioned disk images.
Vagrant Image Creation
----------------------
`Vagrant <https://www.vagrantup.com/>`_ images can be created using the following command::
sudo livemedia-creator --make-vagrant --vagrant-metadata /path/to/metadata.json \
--iso=/path/to/boot.iso --ks=/path/to/fedora-vagrant.ks
The image created is a `vagrant-libvirt
<https://github.com/pradels/vagrant-libvirt>`_ provider image and needs to have
vagrant setup with libvirt before you can use it.
The ``--vagrant-metadata`` file is optional, it will create a minimal one by
default, and if one is passed it will make sure the disk size is setup
correctly. If you pass a ``--vagrant-vagrantfile`` it will be included in the
image verbatim. By default no vagrantfile is created.
There is an example Vagrant kickstart file in the docs directory that sets up
the vagrant user with the default insecure SSH pubkey and a few useful
utilities.
This also works with ``--no-virt``, but will not work inside a mock due to its
use of partitioned disk images and qcow2.
Creating UEFI disk images with virt
-----------------------------------
Partitioned disk images can only be created for the same platform as the host system (BIOS or
UEFI). You can use virt to create BIOS images on UEFI systems, and it is also possible
to create UEFI images on BIOS systems using OVMF. You first need to setup your system with
the OVMF firmware. The details can be `found here linux-kvm OVMF page <http://www.linux-kvm.org/page/OVMF>`_
but it amounts to:
1. Download the firmware.repo from `Gerd Hoffmann <https://www.kraxel.org/repos/>`_ and install it
in /etc/yum.repos.d/
2. Install the edk2.git-ovmf-x64 package
3. Copy /usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd to /usr/share/OVMF/OVMF_CODE.fd
4. Copy /usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd to /usr/share/OVMF/OVMF_VARS.fd
Now you can run livemedia-creator with ``--virt-uefi`` to boot and install using UEFI::
sudo livemedia-creator --make-disk --virt-uefi --iso=/path/to/boot.iso \
--ks=/path/to/fedora-minimal.ks
Make sure that the kickstart you are using creates a /boot/efi partition by including this::
part /boot/efi --fstype="efi" --size=500
.. note::
When using the resulting image with the current version of OVMF (edk2.git-ovmf-x64-0-20151103.b1295.ge5cffca)
it will not boot automatically because there is a problem with the fallback path.
You can boot it by entering the UEFI shell and running EFI/fedora/shim.efi and
then using efibootmgr to setup the correct boot entry.
Debugging problems
------------------
Sometimes an installation will get stuck. When using qemu the logs will
be written to ./virt-install.log and most of the time any problems that happen
will be near the end of the file. lmc tries to detect common errors and will
cancel the installation when they happen. But not everything can be caught.
When creating a new kickstart it is helpful to use vnc so that you can monitor
the installation as it happens, and if it gets stuck without lmc detecting the
problem you can switch to tty1 and examine the system directly.
If it does get stuck the best way to cancel is to use kill -9 on the qemu pid,
lmc will detect that the process died and cleanup.
If lmc didn't handle the cleanup for some reason you can do this:
1. ``sudo umount /tmp/lmc-XXXX`` to unmount the iso from its mountpoint.
2. ``sudo rm -rf /tmp/lmc-XXXX``
3. ``sudo rm /var/tmp/lmc-disk-XXXXX`` to remove the disk image.
Note that lmc uses the lmc- prefix for all of its temporary files and
directories to make it easier to find and clean up leftovers.
The logs from the qemu run are stored in virt-install.log, logs from
livemedia-creator are in livemedia.log and program.log
You can add ``--image-only`` to skip the .iso creation and examine the resulting
disk image. Or you can pass ``--keep-image`` to keep it around after the iso has
been created.
Cleaning up aborted ``--no-virt`` installs can sometimes be accomplished by
running the ``anaconda-cleanup`` script. As of Fedora 18 anaconda is
multi-threaded and it can sometimes become stuck and refuse to exit. When this
happens you can usually clean up by first killing the anaconda process then
running ``anaconda-cleanup``.
Hacking
-------
Development on this will take place as part of the lorax project, and on the
anaconda-devel-list mailing list, and `on github <https://github.com/rhinstaller/lorax>`_
Feedback, enhancements and bugs are welcome. You can use `bugzilla
<https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora&component=lorax>`_ to
report bugs against the lorax component.

lorax-composer
==============
:Authors:
Brian C. Lane <bcl@redhat.com>
``lorax-composer`` is an API server that allows you to build disk images using
`Blueprints`_ to describe the package versions to be installed into the image.
It is compatible with the Weldr project's bdcs-api REST protocol. More
information on Weldr can be found `on the Weldr blog <http://www.weldr.io>`_.
Behind the scenes it uses `livemedia-creator <livemedia-creator.html>`_ and
`Anaconda <https://anaconda-installer.readthedocs.io/en/latest/>`_ to handle the
installation and configuration of the images.
Important Things To Note
------------------------
* As of version 30.7 SELinux can be set to Enforcing. The current state is
logged for debugging purposes and if there are SELinux denials they should
be reported as a bug.
* All image types lock the root account, except for live-iso. You will need to either
use one of the `Customizations`_ methods for setting a ssh key/password, install a
package that creates a user, or use something like `cloud-init` to setup access at
boot time.
Installation
------------
The best way to install ``lorax-composer`` is to use ``sudo dnf install
lorax-composer composer-cli``, this will setup the weldr user and install the
systemd socket activation service. You will then need to enable it with ``sudo
systemctl enable lorax-composer.socket && sudo systemctl start
lorax-composer.socket``. This will leave the server off until the first request
is made. Systemd will then launch the server and it will remain running until
the system is rebooted.
Quickstart
----------
1. Create a ``weldr`` user and group by running ``useradd weldr``
2. Remove any pre-existing socket directory with ``rm -rf /run/weldr/``
A new directory with correct permissions will be created the first time the server runs.
3. Enable the socket activation with ``systemctl enable lorax-composer.socket
&& sudo systemctl start lorax-composer.socket``.
NOTE: You can also run it directly with ``lorax-composer /path/to/blueprints``. However,
``lorax-composer`` does not react well to being started both on the command line and via
socket activation at the same time. It is therefore recommended that you run it directly
on the command line only for testing or development purposes. For real use or development
of other projects that simply use the API, you should stick to socket activation only.
The ``/path/to/blueprints/`` directory is where the blueprints' git repo will
be created, and all the blueprints created with the ``/api/v0/blueprints/new``
route will be stored. If there are blueprint ``.toml`` files in the top level
of the directory they will be imported into the blueprint git storage when
``lorax-composer`` starts.
Logs
----
Logs are stored under ``/var/log/lorax-composer/`` and include all console
messages as well as extra debugging info and API requests.
Security
--------
Some security related issues that you should be aware of before running ``lorax-composer``:
* One of the API server threads needs to retain root privileges in order to run Anaconda.
* Only allow authorized users access to the ``weldr`` group and socket.
Since Anaconda kickstarts are used there is the possibility that a user could
inject commands into a blueprint that would result in the kickstart executing
arbitrary code on the host. Only authorized users should be allowed to build
images using ``lorax-composer``.
lorax-composer cmdline arguments
--------------------------------
.. argparse::
:ref: pylorax.api.cmdline.lorax_composer_parser
:prog: lorax-composer
How it Works
------------
The server runs as root, and as ``weldr``. Communication with it is via a unix
domain socket (``/run/weldr/api.socket`` by default). The directory and socket
are owned by ``root:weldr`` so that any user in the ``weldr`` group can use the API
to control ``lorax-composer``.
At startup the server will check for the correct permissions and
ownership of a pre-existing directory, or it will create a new one if it
doesn't exist. The socket path and group owner's name can be changed from the
cmdline by passing it the ``--socket`` and ``--group`` arguments.
It will then drop root privileges for the API thread and run as the ``weldr``
user. The queue and compose thread still runs as root because it needs to be
able to mount/umount files and run Anaconda.
Composing Images
----------------
The `welder-web <https://github.com/weldr/welder-web/>`_ GUI project can be used to construct
blueprints and create composes using a web browser.
Or use the command line with `composer-cli <composer-cli.html>`_.
Blueprints
----------
Blueprints are simple text files in `TOML <https://github.com/toml-lang/toml>`_ format that describe
which packages, and what versions, to install into the image. They can also define a limited set
of customizations to make to the final image.
Example blueprints can be found in the ``lorax-composer`` `test suite
<https://github.com/weldr/lorax/tree/master/tests/pylorax/blueprints/>`_, with a simple one
looking like this::
name = "base"
description = "A base system with bash"
version = "0.0.1"
[[packages]]
name = "bash"
version = "4.4.*"
The ``name`` field is the name of the blueprint. It can contain spaces, but they will be converted to ``-``
when it is written to disk. It should be short and descriptive.
``description`` can be a longer description of the blueprint, it is only used for display purposes.
``version`` is a `semver compatible <https://semver.org/>`_ version number. If
a new blueprint is uploaded with the same ``version`` the server will
automatically bump the PATCH level of the ``version``. If the ``version``
doesn't match it will be used as is. eg. Uploading a blueprint with ``version``
set to ``0.1.0`` when the existing blueprint ``version`` is ``0.0.1`` will
result in the new blueprint being stored as ``version 0.1.0``.
[[packages]] and [[modules]]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
These entries describe the package names and matching version glob to be installed into the image.
The names must match the names exactly, and the versions can be an exact match
or a filesystem-like glob of the version using ``*`` wildcards and ``?``
character matching.
NOTE: As of lorax-composer-29.2-1 the versions are not used for depsolving,
that is planned for a future release. And currently there are no differences
between ``packages`` and ``modules`` in ``lorax-composer``.
[[groups]]
~~~~~~~~~~
These entries describe a group of packages to be installed into the image. Package groups are
defined in the repository metadata. Each group has a descriptive name used primarily for display
in user interfaces and an ID more commonly used in kickstart files. Here, the ID is the expected
way of listing a group.
Groups have three different ways of categorizing their packages: mandatory, default, and optional.
For purposes of blueprints, mandatory and default packages will be installed. There is no mechanism
for selecting optional packages.
Customizations
~~~~~~~~~~~~~~
The ``[customizations]`` section can be used to configure the hostname of the final image. eg.::
[customizations]
hostname = "baseimage"
This is optional and may be left out to use the defaults.
[customizations.kernel]
***********************
This allows you to append arguments to the bootloader's kernel commandline. This will not have any
effect on ``tar`` or ``ext4-filesystem`` images since they do not include a bootloader.
For example::
[customizations.kernel]
append = "nosmt=force"
[[customizations.sshkey]]
*************************
Set an existing user's ssh key in the final image::
[[customizations.sshkey]]
user = "root"
key = "PUBLIC SSH KEY"
The key will be added to the user's authorized_keys file.
[[customizations.user]]
***********************
Add a user to the image, and/or set their ssh key.
All fields for this section are optional except for the ``name``, here is a complete example::
[[customizations.user]]
name = "admin"
description = "Administrator account"
password = "$6$CHO2$3rN8eviE2t50lmVyBYihTgVRHcaecmeCk31L..."
key = "PUBLIC SSH KEY"
home = "/srv/widget/"
shell = "/usr/bin/bash"
groups = ["widget", "users", "wheel"]
uid = 1200
gid = 1200
If the password starts with ``$6$``, ``$5$``, or ``$2b$`` it will be stored as
an encrypted password. Otherwise it will be treated as a plain text password.
[[customizations.group]]
************************
Add a group to the image. ``name`` is required and ``gid`` is optional::
[[customizations.group]]
name = "widget"
gid = 1130
[customizations.timezone]
*************************
Customizing the timezone and the NTP servers to use for the system::
[customizations.timezone]
timezone = "US/Eastern"
ntpservers = ["0.north-america.pool.ntp.org", "1.north-america.pool.ntp.org"]
The values supported by ``timezone`` can be listed by running ``timedatectl list-timezones``.
If no timezone is setup the system will default to using `UTC`. The ntp servers are also
optional and will default to using the distribution defaults which are fine for most uses.
In some image types there are already NTP servers setup, eg. Google cloud image, and they
cannot be overridden because they are required to boot in the selected environment. But the
timezone will be updated to the one selected in the blueprint.
[customizations.locale]
***********************
Customize the locale settings for the system::
[customizations.locale]
languages = ["en_US.UTF-8"]
keyboard = "us"
The values supported by ``languages`` can be listed by running ``localectl list-locales`` from
the command line.
The values supported by ``keyboard`` can be listed by running ``localectl list-keymaps`` from
the command line.
Multiple languages can be added. The first one becomes the
primary, and the others are added as secondary. One or the other of ``languages``
or ``keyboard`` must be included (or both) in the section.
[customizations.firewall]
*************************
By default the firewall blocks all access except for services that enable their ports explicitly,
like ``sshd``. This command can be used to open other ports or services. Ports are configured using
the port:protocol format::
[customizations.firewall]
ports = ["22:tcp", "80:tcp", "imap:tcp", "53:tcp", "53:udp"]
Numeric ports, or their names from ``/etc/services`` can be used in the ``ports`` enabled/disabled lists.
The blueprint settings extend any existing settings in the image templates, so if ``sshd`` is
already enabled it will extend the list of ports with the ones listed by the blueprint.
If the distribution uses ``firewalld`` you can specify services listed by ``firewall-cmd --get-services``
in a ``customizations.firewall.services`` section::
[customizations.firewall.services]
enabled = ["ftp", "ntp", "dhcp"]
disabled = ["telnet"]
Remember that the ``firewall.services`` are different from the names in ``/etc/services``.
Both are optional, if they are not used leave them out or set them to an empty list ``[]``. If you
only want the default firewall setup this section can be omitted from the blueprint.
NOTE: The ``Google`` and ``OpenStack`` templates explicitly disable the firewall for their environment.
This cannot be overridden by the blueprint.
[customizations.services]
*************************
This section can be used to control which services are enabled at boot time.
Some image types already have services enabled or disabled in order for the
image to work correctly, and cannot be overridden. eg. ``ami`` requires
``sshd``, ``chronyd``, and ``cloud-init``. Without them the image will not
boot. Blueprint services are added to, not replacing, the list already in the
templates, if any.
The service names are systemd service units. You may specify any systemd unit
file accepted by ``systemctl enable`` eg. ``cockpit.socket``::
[customizations.services]
enabled = ["sshd", "cockpit.socket", "httpd"]
disabled = ["postfix", "telnetd"]
[[repos.git]]
~~~~~~~~~~~~~
The ``[[repos.git]]`` entries are used to add files from a `git repository<https://git-scm.com/>`
repository to the created image. The repository is cloned, the specified ``ref`` is checked out
and an rpm is created to install the files to a ``destination`` path. The rpm includes a summary
with the details of the repository and reference used to create it. The rpm is also included in the
image build metadata.
To create an rpm named ``server-config-1.0-1.noarch.rpm`` you would add this to your blueprint::
[[repos.git]]
rpmname="server-config"
rpmversion="1.0"
rpmrelease="1"
summary="Setup files for server deployment"
repo="PATH OF GIT REPO TO CLONE"
ref="v1.0"
destination="/opt/server/"
* rpmname: Name of the rpm to create, also used as the prefix name in the tar archive
* rpmversion: Version of the rpm, eg. "1.0.0"
* rpmrelease: Release of the rpm, eg. "1"
* summary: Summary string for the rpm
* repo: URL of the get repo to clone and create the archive from
* ref: Git reference to check out. eg. origin/branch-name, git tag, or git commit hash
* destination: Path to install the / of the git repo at when installing the rpm
An rpm will be created with the contents of the git repository referenced, with the files
being installed under ``/opt/server/`` in this case.
``ref`` can be any valid git reference for use with ``git archive``. eg. to use the head
of a branch set it to ``origin/branch-name``, a tag name, or a commit hash.
Note that the repository is cloned in full each time a build is started, so pointing to a
repository with a large amount of history may take a while to clone and use a significant
amount of disk space. The clone is temporary and is removed once the rpm is created.
Adding Output Types
-------------------
``livemedia-creator`` supports a large number of output types, and only some of
these are currently available via ``lorax-composer``. To add a new output type to
lorax-composer a kickstart file needs to be added to ``./share/composer/``. The
name of the kickstart is what will be used by the ``/compose/types`` route, and the
``compose_type`` field of the POST to start a compose. It also needs to have
code added to the :py:func:`pylorax.api.compose.compose_args` function. The
``_MAP`` entry in this function defines what lorax-composer will pass to
:py:func:`pylorax.installer.novirt_install` when it runs the compose. When the
compose is finished the output files need to be copied out of the build
directory (``/var/lib/lorax/composer/results/<UUID>/compose/``),
:py:func:`pylorax.api.compose.move_compose_results` handles this for each type.
You should move them instead of copying to save space.
If the new output type does not have support in livemedia-creator it should be
added there first. This will make the output available to the widest number of
users.
Example: Add partitioned disk support
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Partitioned disk support is something that livemedia-creator already supports
via the ``--make-disk`` cmdline argument. To add this to lorax-composer it
needs 3 things:
* A ``partitioned-disk.ks`` file in ``./share/composer/``
* A new entry in the _MAP in :py:func:`pylorax.api.compose.compose_args`
* Add a bit of code to :py:func:`pylorax.api.compose.move_compose_results` to move the disk image from
the compose directory to the results directory.
The ``partitioned-disk.ks`` is pretty similar to the example minimal kickstart
in ``./docs/rhel-minimal.ks``. You should remove the ``url`` and ``repo``
commands, they will be added by the compose process. Make sure the bootloader
packages are included in the ``%packages`` section at the end of the kickstart,
and you will want to leave off the ``%end`` so that the compose can append the
list of packages from the blueprint.
The new ``_MAP`` entry should be a copy of one of the existing entries, but with ``make_disk`` set
to ``True``. Make sure that none of the other ``make_*`` options are ``True``. The ``image_name`` is
what the name of the final image will be.
``move_compose_results()`` can be as simple as moving the output file into
the results directory, or it could do some post-processing on it. The end of
the function should always clean up the ``./compose/`` directory, removing any
unneeded extra files. This is especially true for the ``live-iso`` since it produces
the contents of the iso as well as the boot.iso itself.
Package Sources
---------------
By default lorax-composer uses the host's configured repositories. It copies
the ``*.repo`` files from ``/etc/yum.repos.d/`` into
``/var/lib/lorax/composer/repos.d/`` at startup, these are immutable system
repositories and cannot be deleted or changed. If you want to add additional
repos you can put them into ``/var/lib/lorax/composer/repos.d/`` or use the
``/api/v0/projects/source/*`` API routes to create them.
The new source can be added by doing a POST to the ``/api/v0/projects/source/new``
route using JSON (with `Content-Type` header set to `application/json`) or TOML
(with it set to `text/x-toml`). The format of the source looks like this (in
TOML)::
name = "custom-source-1"
url = "https://url/path/to/repository/"
type = "yum-baseurl"
proxy = "https://proxy-url/"
check_ssl = true
check_gpg = true
gpgkey_urls = ["https://url/path/to/gpg-key"]
The ``proxy`` and ``gpgkey_urls`` entries are optional. All of the others are required. The supported
types for the urls are:
* ``yum-baseurl`` is a URL to a yum repository.
* ``yum-mirrorlist`` is a URL for a mirrorlist.
* ``yum-metalink`` is a URL for a metalink.
If ``check_ssl`` is true the https certificates must be valid. If they are self-signed you can either set
this to false, or add your Certificate Authority to the host system.
If ``check_gpg`` is true the GPG key must either be installed on the host system, or ``gpgkey_urls``
should point to it.
You can edit an existing source (other than system sources), by doing a POST to the ``new`` route
with the new version of the source. It will overwrite the previous one.
A list of existing sources is available from ``/api/v0/projects/source/list``, and detailed info
on a source can be retrieved with the ``/api/v0/projects/source/info/<source-name>`` route. By default
it returns JSON but it can also return TOML if ``?format=toml`` is added to the request.
Non-system sources can be deleted by doing a ``DELETE`` request to the
``/api/v0/projects/source/delete/<source-name>`` route.
The documentation for the source API routes can be `found here <pylorax.api.html#api-v0-projects-source-list>`_
The configured sources are used for all blueprint depsolve operations, and for composing images.
When adding additional sources you must make sure that the packages in the source do not
conflict with any other package sources, otherwise depsolving will fail.
DVD ISO Package Source
~~~~~~~~~~~~~~~~~~~~~~
In some situations the system may want to *only* use a DVD iso as the package
source, not the repos from the network. ``lorax-composer`` and ``anaconda``
understand ``file://`` URLs so you can mount an iso on the host, and replace the
system repo files with a configuration file pointing to the DVD.
* Stop the ``lorax-composer.service`` if it is running
* Move the repo files in ``/etc/yum.repos.d/`` someplace safe
* Create a new ``iso.repo`` file in ``/etc/yum.repos.d/``::
[iso]
name=iso
baseurl=file:///mnt/iso/
enabled=1
gpgcheck=1
gpgkey=file:///mnt/iso/RPM-GPG-KEY-redhat-release
* Remove all the cached repo files from ``/var/lib/lorax/composer/repos/``
* Restart the ``lorax-composer.service``
* Check the output of ``composer-cli status show`` for any output specific depsolve errors.
For example, the DVD usually does not include ``grub2-efi-*-cdboot-*`` so the live-iso image
type will not be available.
If you want to *add* the DVD source to the existing sources you can do that by
mounting the iso and creating a source file to point to it as described in the
`Package Sources`_ documentation. In that case there is no need to remove the other
sources from ``/etc/yum.repos.d/`` or clear the cached repos.

Lorax
=====
:Authors:
Brian C. Lane <bcl@redhat.com>
"I am the Lorax. I speak for the trees [and images]."
The `lorax <https://github.com/rhinstaller/lorax>`_ tool is used to create the
`Anaconda <https://github.com/rhinstaller/anaconda>`_ installer boot.iso as
well as the basic release tree, and .treeinfo metadata file. Its dependencies
are fairly light-weight because it needs to be able to run in a mock chroot
environment. It is best to run lorax from the same release as is being targeted
because the templates may have release specific logic in them. eg. Use the
rawhide version to build the boot.iso for rawhide, along with the rawhide
repositories.
lorax cmdline arguments
-----------------------
.. argparse::
:ref: pylorax.cmdline.lorax_parser
:prog: lorax
--macboot : @replace
Make the iso bootable on UEFI based Mac systems
Default: True
--nomacboot : @replace
Do not create a Mac bootable iso
Default: False
Quickstart
----------
Run this as root to create a boot.iso in ``./results/``::
dnf install lorax
setenforce 0
lorax -p Fedora -v 23 -r 23 \
-s http://dl.fedoraproject.org/pub/fedora/linux/releases/23/Everything/x86_64/os/ \
-s http://dl.fedoraproject.org/pub/fedora/linux/updates/23/x86_64/ \
./results/
setenforce 1
You can add your own repos with ``-s`` and packages with higher NVRs will
override the ones in the distribution repositories.
Under ``./results/`` will be the release tree files: .discinfo, .treeinfo, everything that
goes onto the boot.iso, the pxeboot directory, and the boot.iso under ``./images/``.
Running inside of mock
----------------------
If you are using lorax with mock v1.3.4 or later you will need to pass
``--old-chroot`` to mock. Mock now defaults to using systemd-nspawn which cannot
create the needed loop device nodes. Passing ``--old-chroot`` will use the old
system where ``/dev/loop*`` is setup for you.
How it works
------------
Lorax uses `dnf <https://github.com/rpm-software-management/dnf>`_ to install
packages into a temporary directory, sets up configuration files, it then
removes unneeded files to save space, and creates a squashfs filesystem of the
files. The iso is then built using a generic initramfs and the kernel from the
selected repositories.
To drive these processes Lorax uses a custom template system, based on `Mako
templates <http://www.makotemplates.org/>`_ with the addition of custom
commands (documented in :class:`pylorax.ltmpl.LoraxTemplateRunner`). Mako
supports ``%if/%endif`` blocks as well as free-form python code inside ``<%
%>`` tags and variable substitution with ``${}``. The default templates are
shipped with lorax in ``/usr/share/lorax/templates.d/99-generic/`` and use the
``.tmpl`` extension.
runtime-install.tmpl
~~~~~~~~~~~~~~~~~~~~
The ``runtime-install.tmpl`` template lists packages to be installed using the
``installpkg`` command. This template is fairly simple, installing common packages and
architecture specific packages. It must end with the ``run_pkg_transaction``
command which tells dnf to download and install the packages.
runtime-postinstall.tmpl
~~~~~~~~~~~~~~~~~~~~~~~~
The ``runtime-postinstall.tmpl`` template is where the system configuration
happens. The installer environment is similar to a normal running system, but
needs some special handling. Configuration files are setup, systemd is told to
start the anaconda.target instead of a default system target, and a number of
unneeded services are disabled, some of which can interfere with the
installation. A number of template commands are used here:
* :func:`append <pylorax.ltmpl.LoraxTemplateRunner.append>` to add text to a file.
* :func:`chmod <pylorax.ltmpl.LoraxTemplateRunner.chmod>` changes the file's mode.
* :func:`install <pylorax.ltmpl.LoraxTemplateRunner.install>` to install a file into the installroot.
* :func:`mkdir <pylorax.ltmpl.LoraxTemplateRunner.mkdir>` makes a new directory.
* :func:`move <pylorax.ltmpl.LoraxTemplateRunner.move>` to move a file into the installroot
* :func:`replace <pylorax.ltmpl.LoraxTemplateRunner.replace>` does text substitution in a file
* :func:`remove <pylorax.ltmpl.LoraxTemplateRunner.remove>` deletes a file
* :func:`runcmd <pylorax.ltmpl.LoraxTemplateRunner.runcmd>` run arbitrary commands.
* :func:`symlink <pylorax.ltmpl.LoraxTemplateRunner.symlink>` creates a symlink
* :func:`systemctl <pylorax.ltmpl.LoraxTemplateRunner.systemctl>` runs systemctl in the installroot
runtime-cleanup.tmpl
~~~~~~~~~~~~~~~~~~~~
The ``runtime-cleanup.tmpl`` template is used to remove files that aren't strictly needed
by the installation environment. In addition to the ``remove`` template command it uses:
* :func:`removepkg <pylorax.ltmpl.LoraxTemplateRunner.removepkg>`
remove all of a specific package's contents. A package may be pulled in as a dependency, but
not really used. eg. sound support.
* :func:`removefrom <pylorax.ltmpl.LoraxTemplateRunner.removefrom>`
Removes some files from a package. A file glob can be used, or the --allbut option to
remove everything except a select few.
* :func:`removekmod <pylorax.ltmpl.LoraxTemplateRunner.removekmod>`
Removes kernel modules
The squashfs filesystem
~~~~~~~~~~~~~~~~~~~~~~~
After ``runtime-*.tmpl`` templates have finished their work lorax creates an
empty ext4 filesystem, copies the remaining files to it, and makes a squashfs
filesystem of it. This file is the / of the boot.iso's installer environment
and is what is in the LiveOS/squashfs.img file on the iso.
iso creation
~~~~~~~~~~~~
The iso creation is handled by another set of templates. The one used depends
on the architecture that the iso is being created for. They are also stored in
``/usr/share/lorax/templates.d/99-generic`` and are named after the arch, like
``x86.tmpl`` and ``aarch64.tmpl``. They handle creation of the tree, copying
configuration template files, configuration variable substitution, treeinfo
metadata (via the :func:`treeinfo <pylorax.ltmpl.LoraxTemplateRunner.treeinfo>`
template command). Kernel and initrd are copied from the installroot to their
final locations and then mkisofs is run to create the boot.iso
Custom Templates
----------------
The default set of templates and configuration files from the lorax-generic-templates package
are shipped in the ``/usr/share/lorax/templates.d/99-generic/`` directory. You can
make a copy of them and place them into another directory under ``templates.d``
and they will be used instead if their sort order is below all other directories. This
allows multiple packages to ship lorax templates without conflict. You can (and probably
should) select the specific template directory by passing ``--sharedir`` to lorax.

Product and Updates Images
==========================
Lorax now supports creation of product.img and updates.img as part of the build
process. This is implemented using the installimg template command which will
take the contents of a directory and create a compressed archive from it. The
directory must be created by one of the packages installed by
runtime-install.tmpl or by passing ``--installpkgs <pkgname>`` to lorax at
runtime. The x86, ppc, ppc64le and aarch64 templates all look for
/usr/share/lorax/product/ and /usr/share/lorax/updates/ directories in the
install chroot while creating the final install tree. If there are files in
those directories lorax will create images/product.img and/or
images/updates.img
These archives are just like an anaconda updates image -- their contents are
copied over the top of the filesystem at boot time so that you can drop in
files to add to or replace anything on the filesystem.
Anaconda has several places that it looks for updates, the one for product.img
is in /run/install/product. So for example, to add an installclass to Anaconda
you would put your custom class here:
``/usr/share/lorax/product/run/install/product/pyanaconda/installclasses/custom.py``
If the packages containing the product/updates files are not included as part
of normal dependencies you can add specific packages with the ``--installpkgs``
command or the installpkgs paramater of :class:`pylorax.treebuilder.RuntimeBuilder`
