What is Joomla?

Joomla is a PHP content management system (CMS) for publishing web content. It includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, search, and support for non-english languages.

TL;DR;

Docker Compose

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-joomla/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Why use Bitnami Images?

Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
With Bitnami images the latest bug fixes and features are available as soon as possible.
Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.
Bitnami container images are released daily with the latest distribution packages available.

This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

How to deploy Joomla in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami Joomla Chart GitHub repository.

Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Supported tags and respective `Dockerfile` links

NOTE: Debian 8 images have been deprecated in favor of Debian 9 images. Bitnami will not longer publish new Docker images based on Debian 8.

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

Prerequisites

To run this application you need Docker Engine 1.10.0. Docker Compose is recomended with a version 1.6.0 or later.

How to use this image

Run Joomla with a Database Container

Running Joomla with a database server is the recommended way. You can either use docker-compose or run the containers manually.

Run the application using Docker Compose

This is the recommended way to run Joomla. You can use the following docker-compose.yml template:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - MARIADB_USER=bn_joomla
      - MARIADB_DATABASE=bitnami_joomla
      - ALLOW_EMPTY_PASSWORD=yes
    volumes:
      - 'mariadb_data:/bitnami'
  joomla:
    image: 'bitnami/joomla:latest'
    environment:
      - MARIADB_HOST=mariadb
      - MARIADB_PORT_NUMBER=3306
      - JOOMLA_DATABASE_USER=bn_joomla
      - JOOMLA_DATABASE_NAME=bitnami_joomla
      - ALLOW_EMPTY_PASSWORD=yes
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - 'joomla_data:/bitnami'
    depends_on:
      - mariadb

volumes:
  mariadb_data:
    driver: local
  joomla_data:
    driver: local

Run the application manually

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

Create a new network for the application and the database:

$ docker network create joomla-tier

Create a volume for MariaDB persistence and create a MariaDB container

$ docker volume create --name mariadb_data
$ docker run -d --name mariadb \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MARIADB_USER=bn_joomla \
  -e MARIADB_DATABASE=bitnami_joomla \
  --net joomla-tier \
  --volume mariadb_data:/bitnami \
  bitnami/mariadb:latest

Note: You need to give the container a name in order to Joomla to resolve the host

Create volumes for Joomla persistence and launch the container

$ docker volume create --name joomla_data
$ docker run -d --name joomla -p 80:80 -p 443:443 \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e JOOMLA_DATABASE_USER=bn_joomla \
  -e JOOMLA_DATABASE_NAME=bitnami_joomla \
  --net joomla-tier \
  --volume joomla_data:/bitnami \
  bitnami/joomla:latest

Then you can access your application at http://your-ip/

Persisting your application

If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a volume at the /bitnami path. Additionally you should mount a volume for persistence of the MariaDB data.

The above examples define docker volumes namely mariadb_data and joomla_data. The Joomla application state will persist as long as these volumes are not removed.

To avoid inadvertent removal of these volumes you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

Mount host directories as data volumes with Docker Compose

This requires a minor change to the docker-compose.yml template previously shown:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
      - MARIADB_USER=bn_joomla
      - MARIADB_DATABASE=bitnami_joomla
    volumes:
      - '/path/to/mariadb_persistence:/bitnami'
  joomla:
    image: 'bitnami/joomla:latest'
    environment:
      - JOOMLA_DATABASE_USER=bn_joomla
      - JOOMLA_DATABASE_NAME=bitnami_joomla
      - ALLOW_EMPTY_PASSWORD=yes
    depends_on:
      - mariadb
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - '/path/to/joomla-persistence:/bitnami'

Mount host directories as data volumes using the Docker command line

In this case you need to specify the directories to mount on the run command. The process is the same than the one previously shown:

Create a network (if it does not exist):

$ docker network create joomla-tier

Create a MariaDB container with host volume:

$ docker run -d --name mariadb \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e MARIADB_USER=bn_joomla \
  -e MARIADB_DATABASE=bitnami_joomla \
  --net joomla-tier \
  --volume /path/to/mariadb-persistence:/bitnami \
  bitnami/mariadb:latest

Note: You need to give the container a name in order to Joomla to resolve the host

Create the Joomla container with host volumes:

$ docker run -d --name joomla -p 80:80 -p 443:443 \
  -e ALLOW_EMPTY_PASSWORD=yes \
  -e JOOMLA_DATABASE_USER=bn_joomla \
  -e JOOMLA_DATABASE_NAME=bitnami_joomla \
  --net joomla-tier \
  --volume /path/to/joomla-persistence:/bitnami \
  bitnami/joomla:latest

Upgrade this application

Bitnami provides up-to-date versions of MariaDB and Joomla, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the Joomla container. For the MariaDB upgrade see https://github.com/bitnami/bitnami-docker-mariadb/blob/master/README.md#upgrade-this-image

Get the updated images:

$ docker pull bitnami/joomla:latest

Stop your container

For docker-compose: $ docker-compose stop joomla
For manual execution: $ docker stop joomla

Take a snapshot of the application state

$ rsync -a /path/to/joomla-persistence /path/to/joomla-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

Additionally, snapshot the MariaDB data

You can use these snapshots to restore the application state should the upgrade fail.

Remove the currently running container

For docker-compose: $ docker-compose rm -v joomla
For manual execution: $ docker rm -v joomla

Run the new image

For docker-compose: $ docker-compose up joomla
For manual execution (mount the directories if needed): docker run --name joomla bitnami/joomla:latest

You need to complete the upgrade from the browser to get latest Joomla version.
