docker-dokuwiki
===============

Docker container image with [DokuWiki](https://www.dokuwiki.org/dokuwiki) and apache+php.

###How to run

Assume your docker host is localhost and HTTP public port is 8000 (change these values if you need).

First, run new dokuwiki container:

    docker run -d -p 8000:80 --name dokuwiki vimagick/dokuwiki

Then setup dokuwiki using installer at URL `http://localhost:8000/install.php`

###How to make data persistent

To make sure data won't be deleted if container is removed, create an empty container named `dokuwiki-data` and attach DokuWiki container's volumes to it. Volumes won't be deleted if at least one container owns them.

    # create data container
    docker run --volumes-from dokuwiki --name dokuwiki-data busybox
    
    # now you can safely delete dokuwiki container
    docker stop dokuwiki && docker rm dokuwiki
    
    # to restore dokuwiki, create new dokuwiki container and attach dokuwiki-data volume to it
    docker run -d -p 8000:80 --volumes-from dokuwiki-data --name dokuwiki vimagick/dokuwiki

###How to backup data

    # create dokuwiki-backup.tar.gz archive in current directory using temporaty container
    docker run --rm --volumes-from dokuwiki -v $(pwd):/backup ubuntu tar zcvf /backup/dokuwiki-backup.tar.gz /var/www

###How to restore from backup

    #create new dokuwiki container, but don't start it yet
    docker create -p 8000:80 --name dokuwiki vimagick/dokuwiki
    
    # create data container for persistency (optional)
    docker run --volumes-from dokuwiki --name dokuwiki-data busybox
    
    # restore from backup using temporary container
    docker run --rm --volumes-from dokuwiki -w / -v $(pwd):/backup ubuntu tar xzvf /backup/dokuwiki-backup.tar.gz
    
    # start dokuwiki
    docker start dokuwiki
