composer-cli — Lorax 28.14.21 documentation

# 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

## 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: ami, ext4-filesystem, 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
