Nextcloud with SSL and Docker

Setup of docker

You need to have, on your server, the installed docker. The installation can be done with an official script, following the following steps:

Download the docker

curl -fsSL https://get.docker.com -o get-docker.sh

run the script

sh get-docker.sh

Give permissions to execute the Docker command to your user

sudo usermod -aG docker $USER

Remove the installation script

rm get-docker.sh

Setup of proxy

Follow the instructions of this repository:

https://github.com/LibreCodeCoop/nginx-proxy

Before first run

Copy the .env.example to .env and set the values.

cp .env.example .env

Environment	service	Description
`VIRTUAL_HOST`	`web`	Your domain
`LETSENCRYPT_HOST`	`web`	Your domain
`LETSENCRYPT_EMAIL`	`web`	Your sysadmin email
`NEXTCLOUD_TRUSTED_DOMAINS`	`app`	domains separated by comma. The domain web is mandatory, add your domain together with whe domain web. The domain `web` is the domain of Nginx service.

PS: Let's Encrypt only work in servers when the VIRTUAL_HOST and LETSENCRYPT_HOST have a valid public domain registered in a DNS server. Don't try to use in localhost, don't work!

Create a network

docker network create reverse-proxy
docker network create postgres

After setup

After finish the setup, access this url: https://yourdomain.tld/settings/admin/overview.

If is necessary run any occ command, run like this:

docker compose exec -u www-data app ./occ db:add-missing-indices
docker compose exec -u www-data app ./occ db:convert-filecache-bigint

Custom setup

Customize docker-compose content

You can do this using environments and creating a file called docker-compose.override.yml to add new services.

PHP

Create your .ini file at volumes/php/ folder. Example: volumes/php/xdebug.ini
Alter the file docker-compose.override.yml adding your volume

services:
  app:
    volumes:
      - ./volumes/php/xdebug.ini:/usr/local/etc/php/conf.d/xdebug.ini

Run Nextcloud

# The postgres service is executed separated to be possible reuse this service to other applications that use PostgreSQL
docker compose up -f docker-compose-postgres.yml -d
docker compose up -d
docker compose -d

Use a specific version of Nextcloud

Change the value of NEXTCLOUD_VERSION at .env file and put the tag name that you want to use. Check the availables tags here: https://hub.docker.com/_/nextcloud/tags

Build the images, down the containers and get up again:

docker compose build --pull
docker compose up -d
