Examples section

In this subfolders are some examples how to use the docker image. There are two sections:

The dockerfiles are derived images, that add or alter certain functionalities of the default docker images. In the docker-compose subfolder are examples for deployment of the application, including database, redis, collabora and other services.

Dockerfiles

The Dockerfiles use the default images as base image and build on top of it.

Example	Description
cron	uses supervisor to run the cron job inside the container (so no extra container is needed).
imap	adds dependencies required to authenticate users via imap
smb	adds dependencies required to use smb shares

docker-compose

In docker-compose additional services are bundled to create a complete nextcloud installation. The examples are designed to run out-of-the-box. Before running the examples you have to modify the db.env and docker-compose.yml file and fill in your custom information.

The docker-compose examples make heavily use of dereived Dockerfiles to add configuration files into the containers. This way they should also work on remote docker systems as Docker for Windows. When running docker-compose on the same host as the docker daemon, another possibility would be to simply mount the files in the volumes section in the docker-compose.yml file.

insecure

This example should only be used for testing on the local network because it uses a unencrypted http connection. When you want to have your server reachable from the internet adding HTTPS-encryption is mandatory! For this use one of the with-nginx-proxy examples.

To use this example complete the following steps:

if you use mariadb or mysql choose a root password for the database in docker-compose.yml behind MYSQL_ROOT_PASSWORD=
choose a password for the database user nextcloud in db.env behind MYSQL_PASSWORD= (for mariadb/mysql) or POSTGRES_PASSWORD= (for postgres)
run docker-compose build --pull to pull the most recent base images and build the custom dockerfiles
start nextcloud with docker-compose up -d

If you want to update your installation to a newer version of nextcloud, repeat the steps 3 and 4.

with-nginx-proxy

The nginx proxy adds a proxy layer between nextcloud and the internet. The proxy is designed to serve multiple sites on the same host machine. The advantage in adding this layer is the ability to add a container for Let's Encrypt certificate handling. This combination of the jwilder/nginx-proxy and jrcs/docker-letsencrypt-nginx-proxy-companion containers creates a fully automated https encryption of the nextcloud installation without worrying about certificate generation, validation or renewal.
