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

Setup of database

Follow the instructions of this repository:

https://github.com/LibreCodeCoop/postgres-docker

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

PHP-FPM

• For PHP-FPM modifications, include the following volume to the app service in docker-compose.override.yml file:

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

• Create a file ./volumes/php/pm.ini with the following content (see references for tunning according your setup):

[www]
pm.max_children = 10
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

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

Logs

If you want to see the logs, run:

docker compose logs -f --tail=100

You will see this message in the logs and other many upgrade messages:
