Nextcloud installieren mit Docker ohne Services

Note for english speakers: this is german as by time of writing i decided to do so. It's a working draft with hints but don't expect a full howto guide. Maybe i will write a new one including full flagged Server- Setup. Util then, this is all you will find here.

BTW: Two things to consider before reading this:

1. Portainer does have an own yaml- editor integrated in Stack -Management, which is quite nice to use and makes it easier to start and stop services in larger setups. So don't creat yaml- files on your own, but put the contents in a new stack in the editor there (and make a backup of you portainer- volume!)
2. Nextcloud itself is very powerfull, but gets even really explosive using all of its features! The NC- Devs make it easy to install all of them in one step using https://github.com/nextcloud/all-in-one - check out this mind- blowing experience if your server is fast enough!

There is a big Problem with docker: The Daemon is running as root and also the Container- Services are. I am not a fried of this - so maybe you want to install Docker as non-root- user as wriztten here https://obel1x.de/dokuwiki/doku.php?id=content:serverbasics:docker and come back later.

Dies ist ein einfaches Setup. Nach der Installation von docker, kann folgendes gemacht werden.

Achtung: Docker.service und Containerd.service zusammen funktionieren NICHT ! Sollte Docker einfach nicht starten:

„Yes, that was the problem. Ran systemctl disable containerd then rebooted and docker started as it should.“ Link
