``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 chance 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: ext4-filesystem, live-iso, partitioned-disk, qcow2,
|
||
|
|
tar
|
||
|
|
|
||
|
|
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
