Based on https://github.com/containers/toolbox/pull/371/files.

It used be imported via the docker template, but now it's explicit.

- Push images to the Shore image registry.
- Update template name.

Tag a few of them. Add reg.

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

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.
