Introduction

This project contains the Dockerfile for building a container running XWiki 7.0 on Tomcat with MySQL as a database.

Building

Just run docker build . and you should have your image ready in your docker repository.

Running

When running the container you must specify the following information:

  • Where to mount /var/lib/mysql for database stored data.
  • Where to mount /var/lib/xwiki for XWiki permament data.
  • Where to map port 8080.

Not specifying mount points will make data stored in the wiki disappear when the container is stopped.

Not specifying the port mapping will make XWiki inaccessible from the host.

Here it is the command line to use for starting the XWiki container:

docker run -v HOST_DIR_FOR_XWIKI_DATA:/var/lib/xwiki -v HOST_DIR_FOR_MYSQL_DATA:/var/lib/mysql -p HOST_PORT_FOR_ACCESSING_XWIKI:8080 CONTAINER_ID

Once the container is started, you can open a browser and connect to http://host:HOST_PORT_FOR_ACCESSING_XWIKI/xwiki

Making data dir accessible

In order to make HOST_DIR_FOR_XWIKI_DATA and HOST_DIR_FOR_MYSQL_DATA accessible by the container, they must be executable and writable by the tomcat7 (UID 101, GID 102) and mysql (UID 103, GID 104) container users - which might not exist in your host.

In order to avoid writing problems do a chown 101:103 on HOST_DIR_FOR_XWIKI_DATA, and chown 102:104 on HOST_DIR_FOR_MYSQL_DATA.

Disclaimer

I still need to find a way to shut things down gracefully, so do not use this in production :)
