What is Nextcloud?
A safe home for all your data. Access & share your files, calendars, contacts, mail & more from any device, on your terms.
How to use this image
This image is designed to be used in a micro-service environment. It consists of the Nextcloud installation in an php-fpm container. To use this image it must be combined with any webserver that can proxy the http requests to the FastCGI-port of the container.
Start Nextcloud
Starting Nextcloud php-fpm instance listening on port 9000 is as easy as the following:
$ docker run -d nextcloud
Now you can get access to fpm running on port 9000 inside the container. If you want to access it from the internet, we recommend using a reverse proxy in front. You can install it directly on your machine or use an additional container (You can find more information on that on the docker-compose section). Once you have a reverse proxy, you can access Nextcloud at http://localhost/ and go through the wizard.
By default this container uses SQLite for data storage, but the Nextcloud setup wizard (appears on first run) allows connecting to an existing MySQL/MariaDB or PostgreSQL database. You can also link a database container, e.g. --link my-mysql:mysql, and then use mysql as the database host on setup.
Persistent data
All data beyond that which lives in the database (file uploads, etc) is stored within the default volume /var/www/html. With this volume, Nextcloud will only be updated when the file version.php is not present.
-v /<mydatalocation>:/var/www/html
For fine grained data persistence, you can use 3 volumes, as shown below.
-v /<mydatalocation>/apps:/var/www/html/appsinstalled / modified apps-v /<mydatalocation>/config:/var/www/html/configlocal configuration-v /<mydatalocation>/data:/var/www/html/datathe actual data of your Nextcloud
... via docker-compose
The recommended minimal setup is using this image in combination with two containers: A database container and a reverse proxy for the http connection to the service. A working example can be found at IndieHosters/Nextcloud.
If you want to access your Nextcloud from the internet we recommend configuring your reverse proxy to use encryption (for example via let's Encrypt)
Update to a newer version
To update your Nextcloud version you simply have to pull and start the new container.
$ docker pull nextcloud
$ docker run -d nextcloud
When you access your site the update wizard will show up.
