I built a custom Docker image from the official Nextcloud image, which works with the Raspberry Pi 4 and 5. The Docker compose includes a container for Nextcloud, MySQL database, and a Redis Cache Server. I have also added the fixes for adding more PHP memory and adding additional PHP extensions. Video Thumbnails and corn jobs are also supported.
The how-to shows how to install and set up Nextcloud, nginx reverse proxy, & collaborate online.
Feel Free to take a look and test it out for yourself. If it all works well for you, please let me know, as I am trying to make sure my custom image is quick and easy for anyone else to use.
