Docker container image with DokuWiki and nginx

###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 istepanov/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 istepanov/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 istepanov/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
