Setup

  1. Pull the image
$ docker pull freebyte/docker-dokuwiki-alpine
  1. Create docker named volume
$ docker volume create wiki
  1. Find out what folder is used by the named container
$ docker volume inspect wiki

Example output:

[
    {
        "CreatedAt": "2017-12-30T15:52:20+02:00",
        "Driver": "local",
        "Labels": null,
        "Mountpoint": "/var/lib/docker/volumes/wiki/_data",
        "Name": "wiki",
        "Options": {},
        "Scope": "local"
    }
]
  1. Copy dokuwiki folder into container's folder

Dokuwiki folder maybe either pre-existing (backuped) folder or a new dokuwiki.

For new dokuwiki:

$ cd /var/lib/docker/volumes/wiki/_data
$ curl https://download.dokuwiki.org/src/dokuwiki/dokuwiki-stable.tgz | tar xvz --strip-components 1
  1. Create a new user on the host system to match docker image apache user
useradd --uid 20000 -M -N wikidocker

This creates user with login wikidocker without group and home folder. apache server inside docker container runs with uid 20000, too.

  1. Chown volume folder to wikidocker user
$ chown -R wikidocker /var/lib/docker/volumes/wiki/_data

This makes possible for apache server to access the data in the folder.

Check all is ok:

$ ls /var/lib/docker/volumes/wiki/_data

Example output:

/var/lib/docker/volumes/wiki/_data:
