Deploy Nextcloud with MariaDB in a Podman Pod

With this ansible role you can deploy Nextcloud and MariaDB container in a podman-pod(1) to get a running Nextcloud instance ready to use from the local host. To reach this Nextcloud from a remote location you have two options:

  1. Use a reverse proxy like NGINX to forward requests to your Nextcloud pod.
  2. Listen on all interfaces for incoming traffic for the pod.

I strongly recommend option 1.

This role was tested on Fedora 35 and Debian 11 (Bullseye) so far. Please let me know if you run it with other Distributions and version, so I can add them to meta/main.yml. Any feedback is welcome.

Requirements

  • Collection containers.podman

To install this collection use: ansible-galaxy collection install containers.podman

Role Variables

All variables needed to deploy a pod containing containers for Nextcloud and MariaDB are defined in defaults/main.yml and set to example values. You have to change these values or set them in vars/main.yml to fit your needs. Please keep your passwords as a secret. Use ansible-vault(1) to protect them.
