Overview

I’m using Nextcloud as an on premise backup and storage solution for a local server. I’m using docker to run a bunch of other services so this is to document running Nextcloud on docker.

Nextcloud needs access to a database which we will also need to run via docker. Note the NEXTCLOUD_TRUSTED_DOMAINS and OVERWRITEPROTOCOL variables being set. I’m using an external (not running on docker) nGINX as a reverse proxy so I need to add the domain as a trusted domain which is done by setting the value of that variable.

I was having issues logging in where the main page would get stuck after logging in and then start working again after a refresh. This was only hapenning over https and setting the OVERWRITEPROTOCOL to https seems to fix the issue.

Most of the docker compose should be from the Nextcloud docs. After running docker compose up, the service should be available at localhost:8081.

Docker compose

  ## Database for nextcloud
  nextcloud_db:
    image: mariadb:10.6

nGINX configuration

This is the nGINX config I have for the site

upstream nextcloud_backend {
  server    127.0.0.1:8081;
  keepalive 32;
}

server {
  server_name         nextcloud.example.dev;
  location / {
    proxy_pass http://nextcloud_backend;
    #proxy_set_header Host nextcloud.example.dev;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_buffering off;
    proxy_request_buffering off;
    proxy_set_header X-Real-IP $remote_addr;
    client_max_body_size 10G;
  }
  location /.well-known/carddav {
    return 301 $scheme://$host/remote.php/dav;
  }

  location /.well-known/caldav {
    return 301 $scheme://$host/remote.php/dav;
  }

  listen 443 ssl; ## managed by Certbot
  ssl_certificate /etc/letsencrypt/live/example.dev/fullchain.pem; ## managed by Certbot
  ssl_certificate_key /etc/letsencrypt/live/example.dev/privkey.pem; ## managed by Certbot
  include /etc/letsencrypt/options-ssl-nginx.conf; ## managed by Certbot
  ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; ## managed by Certbot

}

server {
  if ($host = nextcloud.example.dev) {
      return 301 https://$host$request_uri;
  }
  server_name         nextcloud.example.dev;
  listen 80;
    return 404;
}

💡 TL;DR

The post is about setting up Nextcloud on Docker, specifically using MariaDB as the database and Nginx as a reverse proxy. The author encountered an issue where the login page would get stuck after refreshing, but this problem was fixed by enabling HTTPS and setting the OVERWRITEPROTOCOL variable to https.
