<span class="sd">&#39;&#39;&#39;</span>
<span class="sd"> This class parses and executes Lorax templates. Sample usage:</span>
<span class="sd"> # install a bunch of packages</span>
<span class="sd"> runner = LoraxTemplateRunner(inroot=rundir, outroot=rundir, dbo=dnf_obj)</span>
<span class="sd"> runner.run(&quot;install-packages.ltmpl&quot;)</span>
<span class="sd"> # modify a runtime dir</span>
<span class="sd"> runner = LoraxTemplateRunner(inroot=rundir, outroot=newrun)</span>
<span class="sd"> runner.run(&quot;runtime-transmogrify.ltmpl&quot;)</span>
<span class="sd"> NOTES:</span>
<span class="sd"> * Parsing procedure is roughly:</span>
<span class="sd"> 1. Mako template expansion (on the whole file)</span>
<span class="sd"> 2. For each line of the result,</span>
<span class="sd"> a. Whitespace splitting (using shlex.split())</span>
<span class="sd"> b. Brace expansion (using brace_expand())</span>
<span class="sd"> c. If the first token is the name of a function, call that function</span>
<span class="sd"> with the rest of the line as arguments</span>
<span class="sd"> * Parsing and execution are *separate* passes - so you can&#39;t use the result</span>
<span class="sd"> of a command in an %if statement (or any other control statements)!</span>
<span class="sd"> * Commands that run external programs (systemctl, gconfset) currently use</span>
<span class="sd"> the *host*&#39;s copy of that program, which may cause problems if there&#39;s a</span>
<span class="sd"> big enough difference between the host and the image you&#39;re modifying.</span>
<span class="sd"> * The commands are not executed under a real chroot, so absolute symlinks</span>
<span class="sd"> will point *outside* the inroot/outroot. Be careful with symlinks!</span>
<span class="sd"> ADDING NEW COMMANDS:</span>
<span class="sd"> * Each template command is just a method of the LoraxTemplateRunner</span>
<span class="sd"> object - so adding a new command is as easy as adding a new function.</span>
<span class="sd"> * Each function gets arguments that correspond to the rest of the tokens</span>
<span class="sd"> on that line (after word splitting and brace expansion)</span>
<span class="sd"> * Commands should raise exceptions for errors - don&#39;t use sys.exit()</span>

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 virt-install 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 virt-install
``--ks`` to select the kickstart file describing what to install.
To use livemedia-creator with virt-install you will need to install the
following packages, as well as have libvirtd setup correctly.
* ``virt-install``
* ``libvirt-python``
If you are going to be using Anaconda directly, with ``--no-virt`` mode, make sure
you have the anaconda package installed. You can use the anaconda-tui package
to save a bit of space on the build system.
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
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/
If you want to watch the install you can pass ``--vnc vnc`` and use a vnc client
to connect to localhost:0
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 virt-install 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 passing ``--vnc vnc`` and 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
disk 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/
or the directory specified by ``--lorax-templates``
Currently the standard lorax templates are used to make a bootable iso, but
it should be possible to modify them to output other results. They are
written using the Mako template system which is very flexible.
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. Have dracut-config-generic, grub-efi, memtest86+ and syslinux in the package
list.
13. Omit dracut-config-rescue from the %package list: ``-dracut-config-rescue``
One drawback to using virt-install 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/17/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 virt-install 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``
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 ``--qcow2``, for example::
sudo livemedia-creator --make-appliance --iso=/path/to/boot.iso --ks=./docs/fedora-minimal.ks \
--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 virt-install 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.
Using Mock 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 that
this requires bind mounting the host's /dev/ directory into the mock, which
could be dangerous since it includes the host's drives. You can work around
this by /dev/loopX nodes before running livemedia-creator. This example does
not do that.
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. Edit the /etc/mock/site-defaults.cfg file to change:
``config_opts['internal_dev_setup'] = False``
The loop devices are needed for the installation, so it needs to mount the
host's /dev/ inside the mock.
This is fairly dangerous. I would recommend using a dedicated build host and
making sure you have backups just in case something goes wrong and it
modifies the host system. You can avoid this if you setup the /dev/loopX
device nodes yourself.
4. 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'
# NOTE that this actually needs to be set in site-defaults.cfg
config_opts['internal_dev_setup'] = False
# Mount the relevant host paths inside the mock /dev/
config_opts['plugin_conf']['bind_mount_enable'] = True
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/dev','/dev/'))
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/dev/pts','/dev/pts/'))
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/dev/shm','/dev/shm/'))
# build results go into /home/builder/results/
config_opts['plugin_conf']['bind_mount_opts']['dirs'].append(('/home/builder/results','/results/'))
The following steps are run as the builder user who is a member of the mock
group.
5. Make a directory for results matching the bind mount above
``mkdir ~/results/``
6. Copy the example kickstarts
``cp /usr/share/docs/lorax/*ks .``
7. Make sure tar and dracut-network are in the %packages section and that the
``url points to the correct repo``
8. Init the mock
``mock -r fedora-rawhide-x86_64 --init``
9. Copy the kickstart inside the mock
``mock -r fedora-rawhide-x86_64 --copyin ./fedora-minimal.ks /root/``
10. 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.
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 --qcow2``
.. note::
On the RHEL7 version of lmc ``--qcow2`` 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``
Debugging problems
------------------
Sometimes an installation will get stuck. When using virt-install 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 the ``--vnc vnc`` command 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 virsh to destroy the domain.
1. Use ``sudo virsh list`` to show the name of the virt. It will start with LiveOS and contain a UUID.
2. Run ``sudo virsh destroy <name>`` to destroy the domain.
3. Wait 20 seconds or so for lmc to detect that the domain vanished. It should handle cleanup.
If lmc didn't handle the cleanup for some reason you can do this:
1. ``sudo virsh undefine <name>``
2. ``sudo umount /tmp/tmpXXXX`` to unmount the iso from its mountpoint.
3. ``sudo rm -rf /tmp/tmpXXXX``
4. ``sudo rm /var/tmp/diskXXXXX`` to remove the disk image.
The logs from the virt-install 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.

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 command which will take the
contents of a directory and create a compressed archive from it. The x86, ppc,
ppc64le and aarch64 templates all look for /usr/share/lorax/product/ and
/usr/share/lorax/updates/ directories 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`

<h1>Introduction to Lorax<a class="headerlink" href="#introduction-to-lorax" title="Permalink to this headline"></a></h1>
<p>I am the Lorax. I speak for the trees [and images].</p>
<p>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.</p>
</div>
<div class="section" id="before-lorax">
<h1>Before Lorax<a class="headerlink" href="#before-lorax" title="Permalink to this headline"></a></h1>
<p>Tree building tools such as pungi and revisor rely on &#8216;buildinstall&#8217; 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.</p>
<p>EXISTING WORKFLOW:</p>
<p>pungi and other tools call scripts/buildinstall, which in turn call other
scripts to do the image building and data generation. Here&#8217;s how it
currently looks:</p>
<blockquote>
<div><dl class="docutils">
<dt>-&gt; buildinstall</dt>
<dd><ul class="first simple">
<li>process command line options</li>
<li>write temporary yum.conf to point to correct repo</li>
<li>find anaconda release RPM</li>
<li>unpack RPM, pull in those versions of upd-instroot, mk-images,
maketreeinfo.py, makestamp.py, and buildinstall</li>
</ul>
<p>-&gt; call upd-instroot</p>
<p>-&gt; call maketreeinfo.py</p>
<p>-&gt; call mk-images (which figures out which mk-images.ARCH to call)</p>
<p>-&gt; call makestamp.py</p>
<ul class="last simple">
<li>clean up</li>
</ul>
</dd>
</dl>
</div></blockquote>
<p>PROBLEMS:</p>
<p>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&#8217;s not completely clear from reading the scripts.</p>
<p>NEW IDEAS:</p>
<p>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.</p>

<p>livemedia-creator uses <a class="reference external" href="https://github.com/rhinstaller/anaconda">Anaconda</a>,
<a class="reference external" href="https://github.com/rhinstaller/pykickstart">kickstart</a> and <a class="reference external" href="https://github.com/rhinstaller/lorax">Lorax</a> 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.</p>
<p>The general idea is to use virt-install with kickstart and an Anaconda boot.iso
to install into a disk image and then use the disk image to create the bootable
media.</p>
<p>livemedia-creator &#8211;help will describe all of the options available. At the
minimum you need:</p>
<p><tt class="docutils literal"><span class="pre">--make-iso</span></tt> to create a final bootable .iso or one of the other <tt class="docutils literal"><span class="pre">--make-*</span></tt> options.</p>
<p><tt class="docutils literal"><span class="pre">--iso</span></tt> to specify the Anaconda install media to use with virt-install</p>
<p><tt class="docutils literal"><span class="pre">--ks</span></tt> to select the kickstart file describing what to install.</p>
<p>To use livemedia-creator with virt-install you will need to install the
following packages, as well as have libvirtd setup correctly.</p>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">virt-install</span></tt></li>
<li><tt class="docutils literal"><span class="pre">libvirt-python</span></tt></li>
</ul>
<p>If you are going to be using Anaconda directly, with <tt class="docutils literal"><span class="pre">--no-virt</span></tt> mode, make sure
you have the anaconda package installed. You can use the anaconda-tui package
to save a bit of space on the build system.</p>
<p>Conventions used in this document:</p>
<p><tt class="docutils literal"><span class="pre">lmc</span></tt> is an abbreviation for livemedia-creator.</p>
<p><tt class="docutils literal"><span class="pre">builder</span></tt> is the system where livemedia-creator is being run</p>
<p><tt class="docutils literal"><span class="pre">image</span></tt> is the disk image being created by running livemedia-creator</p>
<div class="section" id="quickstart">
<h2>Quickstart<a class="headerlink" href="#quickstart" title="Permalink to this headline"></a></h2>
<p>Run this to create a bootable live iso:</p>
<div class="highlight-python"><div class="highlight"><pre>sudo livemedia-creator --make-iso \
--iso=/extra/iso/boot.iso --ks=./docs/fedora-livemedia.ks
</pre></div>
</div>
<p>You can run it directly from the lorax git repo like this:</p>
<div class="highlight-python"><div class="highlight"><pre>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/
</pre></div>
</div>
<p>If you want to watch the install you can pass <tt class="docutils literal"><span class="pre">--vnc</span> <span class="pre">vnc</span></tt> and use a vnc client
to connect to localhost:0</p>
<p>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.</p>
</div>
<div class="section" id="how-iso-creation-works">
<h2>How ISO creation works<a class="headerlink" href="#how-iso-creation-works" title="Permalink to this headline"></a></h2>
<p>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 <tt class="docutils literal"><span class="pre">--image-only</span></tt>, or to skip the install stage and use
a previously created disk image by passing <tt class="docutils literal"><span class="pre">--disk-image</span></tt> or <tt class="docutils literal"><span class="pre">--fs-image</span></tt></p>
<p>When creating an iso virt-install boots using the passed Anaconda installer iso
and installs the system based on the kickstart. The <tt class="docutils literal"><span class="pre">%post</span></tt> section of the
kickstart is used to customize the installed system in the same way that
current spin-kickstarts do.</p>
<p>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 &#8211;logfile command. You can also monitor the install
by passing <tt class="docutils literal"><span class="pre">--vnc</span> <span class="pre">vnc</span></tt> and 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.</p>
<p>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.</p>
<p>When creating an iso the disk image&#8217;s / partition is copied into a formatted
disk image which is then used as the input to lorax for creation of the final
media.</p>
<p>The final image is created by lorax, using the templates in /usr/share/lorax/
or the directory specified by <tt class="docutils literal"><span class="pre">--lorax-templates</span></tt></p>
<p>Currently the standard lorax templates are used to make a bootable iso, but
it should be possible to modify them to output other results. They are
written using the Mako template system which is very flexible.</p>
</div>
<div class="section" id="kickstarts">
<h2>Kickstarts<a class="headerlink" href="#kickstarts" title="Permalink to this headline"></a></h2>
<p>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.</p>
<p>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.</p>
<ol class="arabic">
<li><p class="first">Flatten the xfce kickstart using ksflatten</p>
</li>
<li><p class="first">Add zerombr so you don&#8217;t get the disk init dialog</p>
</li>
<li><p class="first">Add clearpart &#8211;all</p>
</li>
<li><p class="first">Add swap partition</p>
</li>
<li><p class="first">bootloader target</p>
</li>
<li><p class="first">Add shutdown to the kickstart</p>
</li>
<li><p class="first">Add network &#8211;bootproto=dhcp &#8211;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:</p>
<blockquote>
<div><p><tt class="docutils literal"><span class="pre">livemedia-creator</span> <span class="pre">--kernel-args=&quot;sshd&quot;</span></tt></p>
</div></blockquote>
</li>
<li><p class="first">Add a root password:</p>
<div class="highlight-python"><div class="highlight"><pre>rootpw rootme
network --bootproto=dhcp --activate
zerombr
clearpart --all
bootloader --location=mbr
part swap --size=512
shutdown
</pre></div>
</div>
</li>
<li><p class="first">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.</p>
<blockquote>
<div><p><tt class="docutils literal"><span class="pre">passwd</span> <span class="pre">-d</span> <span class="pre">root</span> <span class="pre">&gt;</span> <span class="pre">/dev/null</span></tt></p>
</div></blockquote>
</li>
<li><p class="first">Remove /etc/fstab in %post, dracut handles mounting the rootfs</p>
<p><tt class="docutils literal"><span class="pre">cat</span> <span class="pre">/dev/null</span> <span class="pre">&gt;</span> <span class="pre">/dev/fstab</span></tt></p>
<p>Do this only for live iso&#8217;s, the filesystem will be mounted read only if
there is no /etc/fstab</p>
</li>
<li><p class="first">Don&#8217;t delete initramfs files from /boot in %post</p>
</li>
<li><p class="first">Have dracut-config-generic, grub-efi, memtest86+ and syslinux in the package
list.</p>
</li>
<li><p class="first">Omit dracut-config-rescue from the %package list: <tt class="docutils literal"><span class="pre">-dracut-config-rescue</span></tt></p>
</li>
</ol>
<p>One drawback to using virt-install 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:</p>
<blockquote>
<div><tt class="docutils literal"><span class="pre">--proxy=http://proxy.yourdomain.com:3128</span></tt></div></blockquote>
<p>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:</p>
<blockquote>
<div><tt class="docutils literal"><span class="pre">url</span> <span class="pre">--url=&quot;http://dl.fedoraproject.org/pub/fedora/linux/development/17/x86_64/os/&quot;</span></tt></div></blockquote>
<p>You can also add an update repo, but don&#8217;t name it updates. Add &#8211;proxy to
it as well.</p>
</div>
<div class="section" id="anaconda-image-install-no-virt">
<h2>Anaconda image install (no-virt)<a class="headerlink" href="#anaconda-image-install-no-virt" title="Permalink to this headline"></a></h2>
<p>You can create images without using virt-install by passing <tt class="docutils literal"><span class="pre">--no-virt</span></tt> on the
cmdline. This will use Anaconda&#8217;s directory install feature to handle the install.
There are a couple of things to keep in mind when doing this:</p>
<ol class="arabic simple">
<li>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.</li>
<li>Make sure selinux is set to permissive or disabled. It won&#8217;t install
correctly with selinux set to enforcing yet.</li>
<li>It may totally trash your host. So far I haven&#8217;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.</li>
</ol>
<p>The logs from anaconda will be placed in an ./anaconda/ directory in either
the current directory or in the directory used for &#8211;logfile</p>
<p>Example cmdline:</p>
<p><tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">livemedia-creator</span> <span class="pre">--make-iso</span> <span class="pre">--no-virt</span> <span class="pre">--ks=./fedora-livemedia.ks</span></tt></p>
</div>
<div class="section" id="ami-images">
<h2>AMI Images<a class="headerlink" href="#ami-images" title="Permalink to this headline"></a></h2>
<p>Amazon EC2 images can be created by using the &#8211;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.</p>
<p>Example cmdline:</p>
<p><tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">livemedia-creator</span> <span class="pre">--make-ami</span> <span class="pre">--iso=/path/to/boot.iso</span> <span class="pre">--ks=./docs/fedora-livemedia-ec2.ks</span></tt></p>
<p>This will produce an ami-root.img file in the working directory.</p>
<p>At this time I have not tested the image with EC2. Feedback would be welcome.</p>
</div>
<div class="section" id="appliance-creation">
<h2>Appliance Creation<a class="headerlink" href="#appliance-creation" title="Permalink to this headline"></a></h2>
<p>livemedia-creator can now replace appliance-tools by using the &#8211;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.</p>
<p>The XML is generated using the Mako template from
/usr/share/lorax/appliance/libvirt.xml You can use a different template by
passing <tt class="docutils literal"><span class="pre">--app-template</span> <span class="pre">&lt;template</span> <span class="pre">path&gt;</span></tt></p>
<p>Documentation on the Mako template system can be found at the <a class="reference external" href="http://docs.makotemplates.org/en/latest/index.html">Mako site</a></p>
<p>The name of the final output XML is appliance.xml, this can be changed with
<tt class="docutils literal"><span class="pre">--app-file</span> <span class="pre">&lt;file</span> <span class="pre">path&gt;</span></tt></p>
<p>The following variables are passed to the template:</p>

<p>livemedia-creator can be used to create un-partitined filesystem images using the
<tt class="docutils literal"><span class="pre">--make-fsimage</span></tt> option. As of version 21.8 this works with both virt-install and no-virt modes

<h2>Using Mock to Create Images<a class="headerlink" href="#using-mock-to-create-images" title="Permalink to this headline"></a></h2>
<p>As of lorax version 22.2 you can use livemedia-creator and anaconda version
22.15 inside of a mock chroot with &#8211;make-iso and &#8211;make-fsimage. Note that
this requires bind mounting the host&#8217;s /dev/ directory into the mock, which
could be dangerous since it includes the host&#8217;s drives. You can work around
this by /dev/loopX nodes before running livemedia-creator. This example does
not do that.</p>
<p>On the host system:</p>
<ol class="arabic">
<li><p class="first">yum install -y mock</p>
</li>
<li><p class="first">Add a user to the mock group to use for running mock. eg. builder</p>
</li>
<li><p class="first">Edit the /etc/mock/site-defaults.cfg file to change:</p>
<p><tt class="docutils literal"><span class="pre">config_opts['internal_dev_setup']</span> <span class="pre">=</span> <span class="pre">False</span></tt></p>
<p>The loop devices are needed for the installation, so it needs to mount the
host&#8217;s /dev/ inside the mock.</p>
<p>This is fairly dangerous. I would recommend using a dedicated build host and
making sure you have backups just in case something goes wrong and it
modifies the host system. You can avoid this if you setup the /dev/loopX
device nodes yourself.</p>
</li>
<li><p class="first">Create a new /etc/mock/ config file based on the rawhide one, or modify the
existing one so that the following options are setup:</p>

<div class="section" id="openstack-image-creation">
<h2>OpenStack Image Creation<a class="headerlink" href="#openstack-image-creation" title="Permalink to this headline"></a></h2>
<p>OpenStack supports partitioned disk images so <tt class="docutils literal"><span class="pre">--make-disk</span></tt> can be used to
create images for importing into glance, OpenStack&#8217;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 <cite>RDO Project
&lt;https://www.rdoproject.org/Quickstart&gt;</cite>.</p>
<p>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&#8217;s disk size.</p>
<p>Create a qcow2 image using the kickstart like this:</p>
<blockquote>
<div><tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">livemedia-creator</span> <span class="pre">--make-disk</span> <span class="pre">--iso=/path/to/boot.iso</span> <span class="pre">--ks=/path/to/fedora-openstack.ks</span> <span class="pre">--qcow2</span></tt></div></blockquote>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">On the RHEL7 version of lmc <tt class="docutils literal"><span class="pre">--qcow2</span></tt> isn&#8217;t supported. You can only create a bare partitioned disk image.</p>
</div>
<p>Import the resulting disk image into the OpenStack system, either via the web UI, or glance on the cmdline:</p>
<div class="highlight-python"><div class="highlight"><pre>glance image-create --name &quot;fedora-openstack&quot; --is-public true --disk-format qcow2 \
--container-format bare --file ./fedora-openstack.qcow2
</pre></div>
</div>
<p>If qcow2 wasn&#8217;t used then <tt class="docutils literal"><span class="pre">--disk-format</span></tt> should be set to raw.</p>
</div>
<div class="section" id="docker-image-creation">
<h2>Docker Image Creation<a class="headerlink" href="#docker-image-creation" title="Permalink to this headline"></a></h2>
<p>Use lmc to create a tarfile as described in the <a class="reference internal" href="#tar-file-creation">TAR File Creation</a> section, but substitute the
fedora-docker.ks example kickstart which removes the requirement for core files and the kernel.</p>
<p>You can then import the tarfile into docker like this (as root):</p>
<blockquote>
<div><tt class="docutils literal"><span class="pre">cat</span> <span class="pre">/var/tmp/fedora-root.tar.xz</span> <span class="pre">|</span> <span class="pre">docker</span> <span class="pre">import</span> <span class="pre">-</span> <span class="pre">fedora-root</span></tt></div></blockquote>
<p>And then run bash inside of it:</p>
<blockquote>
<div><tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">docker</span> <span class="pre">run</span> <span class="pre">-i</span> <span class="pre">-t</span> <span class="pre">fedora-root</span> <span class="pre">/bin/bash</span></tt></div></blockquote>
</div>
<div class="section" id="debugging-problems">
<h2>Debugging problems<a class="headerlink" href="#debugging-problems" title="Permalink to this headline"></a></h2>
<p>Sometimes an installation will get stuck. When using virt-install 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 the <tt class="docutils literal"><span class="pre">--vnc</span> <span class="pre">vnc</span></tt> command 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.</p>
<p>If it does get stuck the best way to cancel is to use virsh to destroy the domain.</p>
<ol class="arabic simple">
<li>Use <tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">virsh</span> <span class="pre">list</span></tt> to show the name of the virt. It will start with LiveOS and contain a UUID.</li>
<li>Run <tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">virsh</span> <span class="pre">destroy</span> <span class="pre">&lt;name&gt;</span></tt> to destroy the domain.</li>
<li>Wait 20 seconds or so for lmc to detect that the domain vanished. It should handle cleanup.</li>
</ol>
<p>If lmc didn&#8217;t handle the cleanup for some reason you can do this:
1. <tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">virsh</span> <span class="pre">undefine</span> <span class="pre">&lt;name&gt;</span></tt>
2. <tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">umount</span> <span class="pre">/tmp/tmpXXXX</span></tt> to unmount the iso from its mountpoint.
3. <tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">rm</span> <span class="pre">-rf</span> <span class="pre">/tmp/tmpXXXX</span></tt>
4. <tt class="docutils literal"><span class="pre">sudo</span> <span class="pre">rm</span> <span class="pre">/var/tmp/diskXXXXX</span></tt> to remove the disk image.</p>
<p>The logs from the virt-install run are stored in virt-install.log,
logs from livemedia-creator are in livemedia.log and program.log</p>
<p>You can add <tt class="docutils literal"><span class="pre">--image-only</span></tt> to skip the .iso creation and examine the resulting
disk image. Or you can pass <tt class="docutils literal"><span class="pre">--keep-image</span></tt> to keep it around after the iso has
been created.</p>
<p>Cleaning up aborted <tt class="docutils literal"><span class="pre">--no-virt</span></tt> installs can sometimes be accomplished by
running the <tt class="docutils literal"><span class="pre">anaconda-cleanup</span></tt> 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 <tt class="docutils literal"><span class="pre">anaconda-cleanup</span></tt>.</p>

<h1>Product and Updates Images<a class="headerlink" href="#product-and-updates-images" title="Permalink to this headline"></a></h1>
<p>Lorax now supports creation of product.img and updates.img as part of the build
process. This is implemented using the installimg command which will take the
contents of a directory and create a compressed archive from it. The x86, ppc,
ppc64le and aarch64 templates all look for /usr/share/lorax/product/ and
/usr/share/lorax/updates/ directories while creating the final install tree. If
there are files in those directories lorax will create images/product.img
and/or images/updates.img</p>
<p>These archives are just like an anaconda updates image &#8211; 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.</p>
<p>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:</p>
<p><tt class="docutils literal"><span class="pre">/usr/share/lorax/product/run/install/product/pyanaconda/installclasses/custom.py</span></tt></p>
<p>If the packages containing the product/updates files are not included as part
of normal dependencies you can add specific packages with the <tt class="docutils literal"><span class="pre">--installpkgs</span></tt>
command or the installpkgs paramater of <a class="reference internal" href="pylorax.html#pylorax.treebuilder.RuntimeBuilder" title="pylorax.treebuilder.RuntimeBuilder"><tt class="xref py py-class docutils literal"><span class="pre">pylorax.treebuilder.RuntimeBuilder</span></tt></a></p>
