HowTo: Ubuntu + Docker + Nextcloud + Talk + Collabora

📑 How to

This is the most complete resource I’ve yet come across for setting up Nextcloud in a Docker container. Thank you @KarlF12! I’ve used it as the basis for my own docker-compose.yml to set up Nextcloud which, at the time of writing this post, is at version 19.0.1.

version: '3.7'

networks:
  nextcloud:

services:
  nextcloud:
    image: nextcloud
    container_name: nextcloud
    networks:
      - nextcloud
    ports:
      - 8000:80
    volumes:
      - ${NEXTCLOUD_ROOT}/html:/var/www/html
      - ${NEXTCLOUD_ROOT}/apps:/var/www/html/custom_apps
      - ${NEXTCLOUD_ROOT}/config:/var/www/html/config
      - ${NEXTCLOUD_ROOT}/files:/svr/nextcloud/data
      - ${NEXTCLOUD_ROOT}/themes:/var/www/html/themes
#    extra_hosts:
#      - ${NEXTCLOUD_FQDN}:${NEXTCLOUD_IPADDRESS}
    depends_on:
      - mariadb
      - redis
    environment:
#      - NEXTCLOUD_TRUSTED_DOMAINS='${NEXTCLOUD_FQDN}'
      - NEXTCLOUD_DATA_DIR=/svr/nextcloud/data
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
      - MYSQL_HOST=nextcloud-mariadb
      - REDIS_HOST=nextcloud-redis
      - TZ=Australia/Perth
      - REDIS_HOST_PASSWORD=${REDIS_PASSWORD}
    restart: unless-stopped

  mariadb:
    image: mariadb
    container_name: nextcloud-mariadb
    volumes:
      - ${NEXTCLOUD_ROOT}/db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=nextcloud-mariadb
      - TZ=Australia/Perth
    networks:
      - nextcloud
    restart: unless-stopped

  redis:
    image: redis
    container_name: nextcloud-redis
    command: redis-server --requirepass ${REDIS_PASSWORD}
    networks:
      - nextcloud
    restart: unless-stopped

The main difference is, it now seems that Redis password authentication is a requirement, otherwise, the following errors appear in logs:

The clue was in this thread [SOLVED] Latest Docker image broke the installation (Redis password auth)

My question is around the bits of the compose file that I’ve commented out.

  1. I’m not sure of the value of the extra_hosts: key. I’ve not noticed any visible difference by removing it.

  2. Autoconfiguration using the environment variable NEXTCLOUD_TRUSTED_DOMAINS does not appear to work. A check of the trusted_domains array in config.php confirms this.

Would you care to comment on these points please?
