How to deploy Joomla with Docker
Follow this step-by-step guide to quickly deploy a containerized version of Joomla – with the help of Docker.
Joomla is a world-class open source content management system, search engine and mobile friendly, multilingual and flexible. it also offers unlimited design potential. With over 110 million downloads, over 10,000 extensions and templates, Joomla is used on over 2 million websites. You can deploy Joomla for corporate websites or portals, e-commerce or online publications.
With the help of Docker, you can quickly deploy a containerized version of Joomla and use it for just about anything. Let’s just do that.

What you will need to deploy Joomla with Docker
I will demonstrate deployment to an Ubuntu Server 22.04 instance using the Docker runtime. You will need a running instance of Ubuntu Server, which can be running on-premises or on a cloud host, such as AWS, Azure, or Google Cloud, and a user with sudo privileges.
How to install Docker
We go the simple route and install Docker from the default repositories. Connect to your Ubuntu server and install Docker with:
sudo apt-get install docker.io -y
Add your user to the docker group
Add your user to the docker group with:
sudo usermod -aG docker $USER
Make the system aware of the new group with:
How to create a network and extract the images
Create a new Docker network
First, we need to create a network for Joomla with the command:
docker network create joomla-network
Next, grab the Joomla and MySQL images with the following commands:
docker pull mysql:5.7
docker pull joomla
How to deploy the database
Create the MySQL volume
First, we will create the volume for the database with the command:
docker volume create mysql-data
Deploy the database
Next, we’ll deploy the database with the command, where PWORD is a unique/strong password:
docker run -d --name joomladb -v mysql-data:/var/lib/mysql --network joomla-network -e "MYSQL_ROOT_PASSWORD=PWORD" -e MYSQL_USER=joomla -e "MYSQL_PASSWORD=PWORD" -e "MYSQL_DATABASE=joomla" mysql:5.7
How to deploy Joomla
Create the Joomla Volume
Now create a volume to hold the Joomla data with the command:
docker volume create joomla-data
We will deploy Joomla with this command, where PWORD is the password you set when deploying the database.
docker run -d --name joomla -p 80:80 -v joomla-data:/var/www/html --network joomla-network -e JOOMLA_DB_HOST=joomladb -e JOOMLA_DB_USER=joomla -e JOOMLA_DB_PASSWORD=PWORD joomla
If port 80 is already in use, you may also need to change the port configuration. For example, you can deploy Joomla on external port 8005 with the command:
docker run -d --name joomla -p 8005:80 -v joomla-data:/var/www/html --network joomla-network -e JOOMLA_DB_HOST=joomladb -e JOOMLA_DB_USER=joomla -e JOOMLA_DB_PASSWORD=PWORD joomla
How to Access the Web Installer
Point your web browser to http://SERVER:PORT, where SERVER is either the IP address or domain of the hosting server, and PORT is the external port you assigned during deployment. You should be greeted by the web installer (Figure A), where you can complete the installation.
The database host will be joomladb as it was containerized and not localhost.
Congratulations! You have just deployed Joomla with the help of Docker. With this process, you can deploy Joomla in any environment that supports Docker.
