The wiki engine behind Wikipedia, for large collaborative knowledge bases with rich version history.

This page describes the Levelrail template for MediaWiki (Applications). It deploys the services below as one Docker Compose app on your own server. Project site: [https://www.mediawiki.org/wiki/Manual:Contents](https://www.mediawiki.org/wiki/Manual:Contents).

Recommended memory: about 512 MiB.

## Services, ports and volumes

| Service | Image | Container ports | Volumes |
