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
-e JOOMLA_DB_USER=...(defaults to "root")
-e JOOMLA_DB_PASSWORD=...(defaults to the value of the
MYSQL_ROOT_PASSWORDenvironment variable from the linked
-e JOOMLA_DB_NAME=...(defaults to "joomla")
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://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
$ docker run --name some-joomla -e JOOMLA_DB_HOST=10.1.2.3:3306 \ -e JOOMLA_DB_USER=... -e JOOMLA_DB_PASSWORD=... -d joomla
docker stack deploy or
version: '3.1' services: joomla: image: joomla links: - joomladb:mysql ports: - 8080:80 environment: JOOMLA_DB_HOST: joomladb JOOMLA_DB_PASSWORD: example joomladb: image: mysql:5.6 environment: MYSQL_ROOT_PASSWORD: example
docker stack deploy -c stack.yml joomla (or
docker-compose -f stack.yml up), wait for it to initialize completely, and visit
http://host-ip:8080 (as appropriate).
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

+1 tto78, same problem
Seeing the same as adiq94. Waited 10 mins and still hangs at "Installing..."
Seems broken (just check it in PWD).
Hangs after third step of installation in infinite request loop from browser.
Save the below code as docker-compose-joomla.yml
joomla: image: joomla links: - joomladb:mysql ports: - 10080:80 volumes: - /srv/docker/smartprojects/joomla_www:/var/www/html environment: JOOMLA_DB_PASSWORD: "CHANGE$This!" restart: always joomladb: image: mysql:5.6 environment: MYSQL_ROOT_PASSWORD: "CHANGE$This!" volumes: - /srv/docker/smartprojects/mysql:/var/lib/mysql ports: #This is exposed in case you want to login to the mysql from the docker host. It is not mandatory to expose it. - 10306:3306 restart: always # The below phpmyadmin is optional. Remove it if you do not require it. # Never expose phpmyadmin to the internet! phpmyadmin: image: phpmyadmin/phpmyadmin environment: - PMA_ARBITRARY=1 restart: always ports: - 10081:80 volumes: - /srv/docker/smartprojects/phpmyadmin/sessions:/sessions links: - joomladb:mysql
Preparations before run:
Create the static folders, where your data will be saved:
mkdir -p /srv/docker/smartprojects/mysql
mkdir -p /srv/docker/smartprojects/joomla_www
mkdir -p /srv/docker/smartprojects/phpmyadmin/sessions
Note that phpmyadmin container is only for your convenience, can be removed.
- Similarly, mysql's port exposed to 10306 to the host is just in case one wants to connect to mysql directly from the host.
How to use it:
To login to the joomla, url is: http://yourdockerhost:10080/
To login to the phpmyadmin, url is: http://yourdockerhost:10081/
To login to phpmyadmin, use: Server:mysql Username:root Password:CHANGE$This!
How to use docker-compose:
to start: docker-compose -f docker-compose-joomla.yml up &
to stop: docker-compose -f docker-compose-joomla.yml stop
to rm: docker-compose -f docker-compose-joomla.yml rm -f
On rm, you will not lose data, as it's kept outside, under /srv/docker/smartprojects. This is the only thing you need to backup, save, etc.
To expose it to the internet, you will want to put an nginx/haproxy in front. I recommend: bringnow/haproxy-letsencrypt:latest
This tutorial and yml files:
As suggested by 'dannchurch', please include the volume mapping in the documentation.
It would be nice if this documentation included a recommendation of of mapping /var/www/html to either a directory on the docker host or to a named volume if one wants to retain configuration/etc across image upgrades.
One can track that down by going to one of the Dockerfile links but would be nice for the DockerHub documentation to be more self-contained in this way.
Hi everyone :) I wanna know, how can I choose specifically a version of PHP ? Thank you,
