Add a Dockerfile that creates a container based on Fedora with
osbuild-composer deployed. Create a suitable entrypoint that runs
osbuild-composer in the container and creates the required sockets
without systemd.
To test this, build the container via:
docker build ./containers/osbuild-composer
Then create your certificates in /etc/osbuild-composer/. Then run
composer with something like:
docker run --rm -v /etc/osbuild-composer:/etc/osbuild-composer <id>
(Where <id> is the container ID returned by `docker build`.)

# osbuild-composer - Containerized OSBuild Composer
|
|
#
|
|
# This container provides a minimal fedora image with the osbuild-composer
|
|
# application installed and configured as default entrypoint.
|
|
#
|
|
# Build Arguments:
|
|
#
|
|
# * OSB_FROM
|
|
# This specifies the host image to use. It must be an RPM-based
|
|
# distribution image with all osbuild-composer requirements
|
|
# pre-installed.
|
|
#
|
|
# Example: "docker.io/library/fedora:latest"
|
|
#
|
|
# * OSB_RPMREPO
|
|
# Base URL of an RPM repository from which to install osbuild-composer
|
|
# from.
|
|
#
|
|
# Example: "https://dl01.fedoraproject.org/pub/fedora/linux/releases/$releasever/Everything/$basearch/os/"
|
|
#
|
|
|
|
# Image arguments must be imported before `FROM`.
|
|
