Nextcloud Container

Inspirations

I needed a few other niceties for my own nextcloud instance, so I made a container based on the official Nextcloud container with them added. Initially I was adding just cron and dependencies for Collabora Built-In. I removed the cron aspect though as it was unreliable and interferred with the update process.

Add-ons

• smbclient
• imagick
• php-ffi

How to handle cron

On the docker host write a bash script that uses the docker command to execute within the container.
Example:

#!/bin/bash
# checks if the docker daemon is running
if [ -f "/var/run/dockerd.pid" ]; then
    echo "Docker is running.... Checking on Nextcloud container"
    # checks if container with name Nextcloud and image tetricz/nextcloud is running
    if [ "$(docker ps -q -f name=Nextcloud | grep tetricz/nextcloud)" ]; then
        echo "Container is running. Executing cron"
        # executes cronjob with user www-data inside container
        docker exec -u www-data Nextcloud php cron.php
    else
        echo "Container is not running."
    fi
else
    echo "Docker is not running..."
fi

To access OCC

It is similar to the method used to handle cron.

docker exec -u www-data -it Nextcloud /var/www/html/occ
