I’m not sure if your goal is to set up nextcloud or to learn docker compose while setting up nextcloud. If you just want it up and running, you could use DockSTARTer to get it going. Heck, even if your goal is mainly learning, you can always tear apart the compose file that dockstarter generates and compare it to your own.

I remember cursing allot with trying nextcloud to work :D and than my serber crashed. I’m currently reinstalling everything but haven’t had the courage to get going on nextcloud.

Nextcloud is very easy to setup as a container. You just need a MySQL/MariaDB server and a volume mount. Just make sure the volume is owned by www-data user (uid:gid 33:33). That’s it. Most problems I’ve seen so far are related to files permissions, so double check to make sure the volume is owned by www-data.

I put together a repo that you should be able to pull down and get running pretty quickly using docker compose. Check it out and let me know if you have any questions.

Have you tried their AIO stack? It’s really easy to setup, but I haven’t gone beyond that because of performance issues on my server

As others have commented, Nextcloud provide an all-in-one docker set up. I managed to follow the instructions and get it working.

However, in the end, I wanted this to replace my Dropbox subscription, and my files and reliable access to them are important to me. Given that, and my relatively low skill level, I didn’t want to futz with troubleshooting failed updates and server issues, so I just went with a Hetzner storage share, which is their managed nextcloud subscription: https://www.hetzner.com/storage/storage-share

Here’s my docker-compose.yml for nextcloud (with minor privacy changes) that includes onlyoffice and drawio containers. SSL is not included and should be handled by NPM and you’ll need a proxy host for both drawio and onlyoffice. I use NPM in docker so I just add it to the docs network instead of exposing any additional ports. For onlyoffice the secret key gets regenerated each time the container starts so you’ll need to update onlyoffice setting in nextcloud each time (unless someone has a better solution). You can get the secret key by logging into the onlyoffice container and running

cat /etc/onlyoffice/documentserver-example/local.json

I’ve been running this solution for a few years without any major issues.

A bit of a sidenote and definitely an unpopular opinion coming up… The nextcloud snap is perhaps the easiest and among the most stable ways to run NC. And I base this on my own experience, having installed and tested NC on numerous devices in several ways. You loose some tinkerability and the performance is nothing to write home about. And yes I know - snap no good - Canonical evil. That having been said, If stability and easy setup is what you want, it’s worth considering.

I’ve been fighting nextckoud over the last few days. I got it up and running, yay. But the. I could not get Nextcloud office or Onlyoffice to work at all.

I used the AIO docker install and followed all the instructions for setup behind cloudflare tunnels but I’m guessing it’s something to do with that, but I just don’t have the time or patience to spend hours trying to troubleshoot why I can install onlyoffice but it won’t allow me to create documents.

I may revisit in the future but the frustration levels are just too high atm.

FYI docker images binding to an NFS mount can be tricky due to ACL extensions not being supported. Podman is especially bad for this.

Maybe give cloudflared a try. Works for me even with nextcloud’s ssl (don’t think there’s a way to start NC without the self-signed cert). Couldn’t get it to work with NPM (I admittedly don’t know much about nginx) so I brought in the big gun(s).

I would recommend going with the Docker AIO install, it does a lot of the heavy lifting for you as well as dealing with backups and updates for long term maintenance.

Their official image is easy to run, just one container needed: https://hub.docker.com/_/nextcloud

Linuxserver.io images are also good: https://hub.docker.com/r/linuxserver/nextcloud

With nginx

https://github.com/nextcloud/docker#base-version---fpm

With caddy

https://caddy.community/t/example-docker-nextcloud-fpm-caddy-v2-webserver/9407

I oersonaly run fpm with caddy

Remember to create your admin account on first run and then add your trusted domain

Admin

• navigate to localhost:8080
• create admin acount
• write down your credestials

allowed domains

• docker ps
• copy container id of nextcloud:fpm
• docker exec --user www-data container_id php occ config:system:set trusted_domains 2 --value=your_domain_name_here
• docker stop container_id
• docker start container_id
