Docker image for MoinMoin (moin) Wiki

This image is a moinmoin wiki in a Debian container.

Feature List

• Moin from Debian, including Xapian search, etc.
• Fast mod_wsgi support
• Based on my proxied-app-apache⁠, inheriting its features:
  • Correct source IP logging
  • Good integration with my reverse-proxy-apache and its automatic letsencrypt SSL cert handling
  • automated security patches for the OS, openssl, and Apache
  • Real init with zombie process reaping
  • Clean shutdown support
  • See the above URL for details.
• Support for automating the process of requesting and updating your SSL certificates from letsencrypt, making the process completely transparent and automatic - should you wish to use it.
• Low memory requirements and efficient.
• Based on Apache, so it's what you (probably) already know.

Use

Start with FROM jgoerzen/moin.

If using behind a reverse proxy, set the environment variable PROXYCLIENT_AUTHORIZED to the IP or IP+netmask of the authorized proxies. This step is not necessary if you are listening directly.

Drop files in /etc/apache2/sites-avaialable, looking something like this:

<VirtualHost *:80>
ServerName www.example.com
Include sites-available/moin-common-sites
</VirtualHost>

Don't forget to a2ensite each one in your donfig.

Set up the config files in /etc/moin, especially farmconfig, as documented in /usr/share/doc/python-moinmoin.

Your moin installation directories, wherever you put them, should be owned by the user www-data. The moin url_prefix_static should be /moin_static in the default configuration.

Final note

Finally, make sure to end your Dockerfile with CMD ["/usr/local/bin/boot-debian-base"].

Recommended Parameters

I recommend you to run your containers with:

docker run -td --stop-signal=SIGRTMIN+3 \
  --tmpfs /run:size=100M --tmpfs /run/lock:size=100M \
  -v /sys/fs/cgroup:/sys/fs/cgroup:ro \
  --name=name -t -d --net=whatever

Recommended Volumes

I recommend that you add VOLUME ["/var/log/apache2"] to your Dockerfile. When rebuilding and restarting your containers, use a sequence such as:

docker stop web
docker rename web web.old
docker run <<parameters>> --volumes-from=web.old  --name-web ....
docker rm web.old

This will let your logs persist, and will avoid unnecessary calls to letsencrypt to obtain new certs. The latter is important to avoid false expiration emails and hitting their rate limiting.

Of course, you will also want your moin directory, wherever you put it, to be persistent. Most would probably mount it as a volume from the host machine.
