For getting secrets out of Keepass on the command line.

Per https://github.com/containers/toolbox/#image-requirements.

I think it's causing to build to fail (only reason it seems).

The Docker project one. Also, address some warnings.

Now I should be able to access services from different containers.

They have dependnecy requirements that conflict with other packages.
Weird considering they've been recently updates yet still require older
versions.

Needed for OSTree and Azafea.

I'm not sure why that's better, but I remember checking it out and
deciding on that.

Things that don't come easily packaged, use the Makefile from rcfiles.

Not sure how I'll manage Virtualbox inside the container.

- Disable the Docker pre-commit checks only in CI (the issue doesn't
happen locally).
- Pull images during the build stage.

- User namespace.
- Install podman.

How could I forget?!

Replicate what's on the host.

Needed for the various DB CLI utils.

- Use CMD instead of ENTRYPOINT to launch sshd (easier to overwrite when
using locally).
- Expose port 22.

Installed from their repository.

For checking the deployment.

Needed headers for some Python packages.

There's no need to run it in a specific runner, but I did because I
set tags on the runners but didn't set them to run untagged (fixed in
gitlab-runner-docker@dfc42dda).

Those hooks fail because we run pre-commit inside of a Docker container
(see https://github.com/pre-commit/pre-commit/issues/1387).

Setup pre-commit and add it to CI. Correct a few things as well.

Pull a new image and build without caching. I want updates for existing
packages without changing files.

- Image with Debian, Python and Golang packages installed.
- Deployment with Docker Compose and GitLab CI.

Standard stuff, really.
