- [It has been reported](https://github.com/Wonderfall/dockerfiles/issues/37) that this image might not work well with old versions of aufs. Please update aufs to 4.x or later, or use overlay/btrfs as a replacement.
- A Redis sever is now running, so you may want to configure it for file locking cache if your config.php was not generated recently. [For best performance it is recommended by Nextcloud documentation](https://docs.nextcloud.com/server/10/admin_manual/configuration_server/caching_configuration.html#additional-notes-for-redis-vs-apcu-on-memory-caching). Add the following lines to your `config.php` :
Other tags than `daily` are built weekly. For security reasons, you should occasionally update the container, even if you have the latest version of Nextcloud.
Basically, you can use a database instance running on the host or any other machine. An easier solution is to use an external database container. I suggest you to use MariaDB, which is a reliable database server. You can use the official `mariadb` image available on Docker Hub to create a database container, which must be linked to the Nextcloud container. PostgreSQL can also be used as well.
Pull the image and create a container. `/mnt` can be anywhere on your host, this is just an example. Change `MYSQL_ROOT_PASSWORD` and `MYSQL_PASSWORD` values (mariadb). You may also want to change UID and GID for Nextcloud, as well as other variables (see *Environment Variables*).
Now you have to use a **reverse proxy** in order to access to your container through Internet, steps and details are available at the end of the README.md. And that's it! Since you already configured Nextcloud through setting environment variables, there's no setup page.
This image is available for `armhf` (Raspberry Pi 1 & 2, Scaleway C1, ...). Although Docker does support ARM-based devices, Docker Hub only builds for x86_64. That's why you will have to build this image yourself! Don't panic, this is easy.
Pull a newer image, then recreate the container as you did before (*Setup* step). None of your data will be lost since you're using external volumes. If Nextcloud performed a full upgrade, your apps could be disabled, enable them again.
I advise you to use [docker-compose](https://docs.docker.com/compose/), which is a great tool for managing containers. You can create a `docker-compose.yml` with the following content (which must be adapted to your needs) and then run `docker-compose up -d nextcloud-db`, wait some 15 seconds for the database to come up, then run everything with `docker-compose up -d`, that's it! On subsequent runs, a single `docker-compose up -d` is sufficient!
Personally I'm using nginx, so if you're using nginx, there are two possibilites :
- nginx is on the host : get the Nextcloud container IP address with `docker inspect nextcloud | grep IPAddress\" | head -n1 | grep -Eo "[0-9.]+" `. But whenever the container is restarted or recreated, its IP address can change. Or you can bind Nextcloud HTTP port (8888) to the host (so the reverse proxy can access with `http://localhost:8888` or whatever port you set), but in this case you should consider using a firewall since it's also listening to `http://0.0.0.0:8888`.
- nginx is in a container, things are easier : you can link nextcloud container to an nginx container so you can use `proxy_pass http://nextcloud:8888`. If you're interested, I provide a nginx image available on Docker Hub : `wonderfall/boring-nginx`, and it comes with a script called `ngxproxy`, which does all the magic after asking you a few questions. Otherwise, an example of configuration would be :
Headers are already sent by the container, including HSTS, so there's no need to add them again. **It is strongly recommended to use Nextcloud through an encrypted connection (HTTPS).** [Let's Encrypt](https://letsencrypt.org/) provides free SSL/TLS certificates (trustworthy!).
