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 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 apply.
composer-cli cmdline arguments¶
Lorax Composer commandline tool
usage: composer-cli [-h] [-j] [-s SOCKET] [--log LOG] [-a APIVER]

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.
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
