Run a Joomla CMS in Podman Pod

One of the special feature of podman over docker is, podman has the concept of pod. Pod is a feature to group containers together. One example is, is lets say we want to deploy a joomla stack. The stack can be deployed in a pod, so that the containers can be managed together, without having to operate on each single component of the stack.

To create a pod with port 8080 on localhost will be redirected to port 80 in a pod
$ podman pod create --name mypod --publish 8080:80

Next, create a container for database that belongs to our pod above
$ podman run -dit --pod mypod -e MYSQL_DATABASE=joomla -e MYSQL_USER=joomlauser -e MYSQL_PASSWORD=joomlapassword -e MYSQL_ROOT_PASSWORD=rootpw --name mariadb docker.io/library/mariadb 

Check whether your mariadb container is ready, by viewing its logs
$ podman logs -f mariadb

After that create a joomla container. Since both the containers are in the same pod, joomla container can refer to mariadb with just 127.0.0.1 since both of them share the same network namespace in a pod
$ podman run -dit --pod mypod -e JOOMLA_DB_HOST=127.0.0.1 -e JOOMLA_DB_USER=joomlauser -e JOOMLA_DB_PASSWORD=joomlapassword -e JOOMLA_DB_NAME=joomla --name joomla docker.io/library/joomla

Similar to mariadb container, you can check whether your joomla container is ready by viewing its logs
$ podman logs -f joomla

Start a browser, and browse to http://0.0.0.0:8080. You should be able to access the joomla web interface. Continue with the installation using the web interface. Make sure you put 127.0.0.1 for the database host information in the web installer.
