Container configuration directory can be set in the .env file which is
automatically used by docker-compose. The default value is the one used
previously (containers/config).
The HACKING.md guide is updated to describe how to set this and how it
affects other commands.
Yesterday, I spent more hours than I would like to admit debugging tests that
was failing because the Fedora cloud base image has only 4 GB disk space.
This commit adds a note for the future me.
tools/gen-user-data generates a cloud-init user-data file from a
configuration directory. It is mostly useful to embed files in the
user-data.
tools/deploy-qemu uses above tool to make a user-data file and spins up
a virtual machine with it. This is useful to locally run, test, and
debug osbuild-composer.
A simple user-data directory for running tests locally is included in
tests/deploy-user-data. It expects a repository with osbuild-composer
rpms to be served on the host's port 8000.
