Usage

Standalone

You can run Nextcloud without a separate database, but I don't recommend it for production setups as it uses SQLite. Another solution is to use an external database provided elsewhere, you can enter the credentials in the installer.

1. Pull the image: docker pull rootlogin/nextcloud
2. Run it: docker run -d --name nextcloud -p 80:80 -v my_local_data_folder:/data rootlogin/nextcloud (Replace my_local_data_folder with the path where do you want to store the persistent data)
3. Open localhost and profit!

The first time you run the application, you can use the Nextcloud setup wizard to install everything. Afterwards it will run directly.

With a database container

For standard setups I recommend the use of MariaDB, because it is more reliable than SQLite. For example, you can use the offical docker image of MariaDB. For more information refer to the according docker image.

# docker pull rootlogin/nextcloud && docker pull mariadb:10
# docker run -d --name nextcloud_db -v my_db_persistence_folder:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=supersecretpassword -e MYSQL_DATABASE=nextcloud -e MYSQL_USER=nextcloud -e MYSQL_PASSWORD=supersecretpassword mariadb:10
# docker run -d --name nextcloud --link nextcloud_db:nextcloud_db -p 80:80 -v my_local_data_folder:/data rootlogin/nextcloud

The auto-connection of the database to nextcloud is not implemented yet. This is why you need to do that manually.

Configuration

You can configure Nextcloud via the occ command:

# docker exec -ti nextcloud occ [...YOUR COMMANDS...]

The command uses the same user as the webserver.

Other

Migrate from OwnCloud

You can easily migrate an existing OwnCloud to this Nextcloud docker image.

Before starting, always make a backup of your old OwnCloud instance. I told you so!

1. Enable the maintenance mode on your old OwnCloud instance, e.g. sudo -u www-data ./occ maintenance:mode --on
2. Create a new folder e.g. /var/my_nextcloud_data
3. Create a new subfolder called "config" and copy the config.php from your existing instance in there.
4. Copy your existing "data" folder to /var/my_nextcloud_data/data
5. Start the docker container: docker run -d --name nextcloud -p 80:80 -v /var/my_nextcloud_data:/data rootlogin/nextcloud
6. Wait until everything is running.
7. Start the Nextcloud migration command: docker exec nextcloud occ upgrade
8. Disable the maintenance mode of Nextcloud: docker exec nextcloud occ maintenance:mode --off
9. Profit!

Run container with systemd

I usually run my containers on behalf of systemd, with the following config:

[Unit]
Description=Docker - Nextcloud container
Requires=docker.service
After=docker.service

[Service]
Restart=always
ExecStart=/usr/bin/docker run -p 127.0.0.1:8000:80 -v /data/nextcloud:/data --name nextcloud rootlogin/nextcloud
ExecStop=/usr/bin/docker stop -t 2 nextcloud ; /usr/bin/docker rm -f nextcloud

[Install]
WantedBy=default.target

NGinx frontend proxy

This container does not support SSL or similar and is therefore not made for running directly in the world wide web. You better use a frontend proxy like another NGinx.

Here are some sample configs (The config need to be adapted):

server {
	listen 80;
	server_name cloud.example.net;

	# ACME handling for Letsencrypt
	location /.well-known/acme-challenge {
  	alias /var/www/letsencrypt/;
  	default_type "text/plain";
 		try_files $uri =404;
	}

	location / {
  	return 301 https://$host$request_uri;
	}
}

server {
  listen 443 ssl spdy;
  server_name cloud.example.net;

	ssl_certificate /etc/letsencrypt.sh/certs/cloud.example.net/fullchain.pem;

	ssl_dhparam /etc/nginx/dhparam.pem;
	ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    client_max_body_size 10G;

    proxy_pass http://127.0.0.1:8000;
  }
}

Frequently Asked Questions

Why does the start take so long?

When you run the container it will reset the permissions on the /data folder. This means if you have much data, it takes some time. This helps to avoid permission issues.

Overwritten config

Some parameters in the Nextcloud configuration will be overwritten by the file in root/opt/nextcloud/config/docker.config.php

Group/User ID

You can change the numerical user id and group id via build arguments.

$ git clone https://github.com/chrootLogin/docker-nextcloud.git && cd docker-nextcloud
$ docker build -t rootlogin/nextcloud --build-arg UID=1000 --build-arg GID=1000 .
$ docker run -p 80:80 rootlogin/nextcloud
