 At first make sure you have chosen the right base image (fpm or apache) and added the features you wanted (see below). In every case you want to add a database container and docker volumes to get easy access to your persistent data. When you want to have your server reachable from the internet adding HTTPS-encryption is mandatory! See below for more information.

 ## Base version - FPM
 When using the FPM image you need another container that acts as web server on port 80 and proxies the requests to the Nextcloud container. In this example a simple nginx container is combined with the Nextcloud-fpm image and a MariaDB database container. The data is stored in docker volumes. The nginx container also need access to static files from your Nextcloud installation. It gets access to all the volumes mounted to Nextcloud via the `volumes_from` option.The configuration for nginx is stored in the configuration file `nginx.conf`, that is mounted into the container. An example can be found in the examples section [here](https://github.com/nextcloud/docker/tree/master/.examples).
