  • docker-systemctl-replacement as a SystemD systemctl shim

  • git to be able to read current repository

  • gron to be able to parse a JSON response

  • jq to be able to parse a JSON response

  • make to enable building Dockerfiles via Makefile

  • moreutils to have tools such as sponge

  • pipx to be able to install Python packages

  • pre-commit preinstalled for Python jobs

  • python3-tomli to be able to read pyproject.toml

  • python3-venv to be able to install Python packages. (deprecated in favor of uv)

  • rsync to be able to handle remote file repositories and merging

  • sphinx, and dependencies, preinstalled for Python jobs

  • uv as a unified pip, virtualenv, pip-tools, …
