The composer project is a set of HTTP services for composing operating system images. It builds on the pipeline execution engine of osbuild [1] and defines its own class of images that it supports building.
Multiple APIs are available to access a composer service. This includes support for the lorax-composer [2] API, and as such can serve as drop-in replacement for lorax-composer.
You can control a composer instance either directly via the provided APIs, or through higher-level user-interfaces from external projects. This, for instance, includes a Cockpit Module [3] or using the composer-cli [4] command-line tool.
Composer does not ship with frontends itself. However, several external frontends for Composer already exist. These include:
To deploy a composer instance, all you need is to
# systemctl start osbuild-composer.socket
Now you can access the service using composer-cli, for example:
# composer-cli status show
or using Cockpit with the Cockpit Composer module from a browser: http://localhost:9090
