DokuWiki

DokuWiki is a lightweight, file-based wiki, no database required, set up early on to document how the infrastructure is built and keep rebuild tutorials, plus host game notes and other miscellaneous notes. In practice it ended up barely used: Ansible and GitLab already serve as living infrastructure documentation, and Joplin’s Markdown support turned out to be a better fit for personal notes, so DokuWiki has stayed mostly idle since. Pages are stored as plain text files, which makes them trivial to back up alongside the rest of the Docker host’s data.

It runs through the generic Compose stack rather than a dedicated role; the underlying Docker volume data is covered by docker_data_backup.
