What is Joomla?

Joomla is a free and open-source content management system (CMS) for publishing web content. It is built on a model–view–controller web application framework that can be used independently of the CMS. Joomla is written in PHP, uses object-oriented programming (OOP) techniques and software design patterns, stores data in a MySQL, MS SQL, or PostgreSQL database, and includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, search, and support for language internationalization.

How to use this image

$ docker run --name some-joomla --link some-mysql:mysql -d joomla

The following environment variables are also honored for configuring your Joomla instance:

  • -e JOOMLA_DB_HOST=... (defaults to the IP and port of the linked mysql container)
  • -e JOOMLA_DB_USER=... (defaults to “root”)
  • -e JOOMLA_DB_PASSWORD=... (defaults to the value of the MYSQL_ROOT_PASSWORD environment variable from the linked mysql container)
  • -e JOOMLA_DB_NAME=... (defaults to “joomla”)

If the JOOMLA_DB_NAME specified does not already exist on the given MySQL server, it will be created automatically upon startup of the joomla container, provided that the JOOMLA_DB_USER specified has the necessary permissions to create it.

If you’d like to be able to access the instance from the host without the container’s IP, standard port mappings can be used:

$ docker run --name some-joomla --link some-mysql:mysql -p 8080:80 -d joomla

Then, access it via http://localhost:8080 or http://host-ip:8080 in a browser.

If you’d like to use an external database instead of a linked mysql container, specify the hostname and port with JOOMLA_DB_HOST along with the password in JOOMLA_DB_PASSWORD and the username in JOOMLA_DB_USER (if it is something other than root):

$ docker run --name some-joomla -e JOOMLA_DB_HOST=10.1.2.3:3306 \
    -e JOOMLA_DB_USER=... -e JOOMLA_DB_PASSWORD=... -d joomla

… via docker-compose

Example docker-compose.yml for joomla:

joomla:
  image: joomla
  links:
    - joomladb:mysql
  ports:
    - 8080:80

joomladb:
  image: mysql:5.6
  environment:
    MYSQL_ROOT_PASSWORD: example

Run docker-compose up, wait for it to initialize completely, and visit http://localhost:8080 or http://host-ip:8080.

Adding additional libraries / extensions

This image does not provide any additional PHP extensions or other libraries, even if they are required by popular plugins. There are an infinite number of possible plugins, and they potentially require any extension PHP supports. Including every PHP extension that exists would dramatically increase the image size.

If you need additional PHP extensions, you’ll need to create your own image FROM this one. The documentation of the php image explains how to compile additional extensions. Additionally, the joomla Dockerfile has an example of doing this.

The following Docker Hub features can help with the task of keeping your dependent images up-to-date:

  • Automated Builds let Docker Hub automatically build your Dockerfile each time you push changes to it.
  • Repository Links can ensure that your image is also rebuilt any time joomla is updated.
