- Use CI templates.
- Use common pre-commit config from snippet.
- Address pre-commit issues.

Can't deploy with the runner, the jobs fail because the runner is
restarted during. Do the pull and build with the CI, but the actual
deployment with a script locally.

Can't use the "host" variable as the tag. Workaround that with YAML
anchors (ugly but works).

- New version.
- pre-commit.
- GitLab CI/CD.
- Always pull new images.
