Please help with NC on docker deployment

🚧 Installation
1

Hi NC experts,

i’d like to move off of a NC hosted on a VM to a NC instance on docker & been struggling to bring container up

I have a Ubuntu VM that is hosting already 10+ different containers and i’d like deploy NC on the same host, but i would like to use dedicated static IP, not just a port the IP for my NC would be 192.168.11.6 All other traffic (between NC and DB, would be internal to the host)

i used this to create my docker-compose.yml: https://github.com/nextcloud/docker/blob/master/.examples/docker-compose/insecure/mariadb/apache/docker-compose.yml

this is my docker-compose.yml:

version: '3'

services:
  db:
    image: mariadb:10.5
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    restart: always
    volumes:
      - ./db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=password
    env_file:
      - db.env
    networks:
      - internal

  redis:
    image: redis:alpine
    restart: always

  app:
    image: nextcloud:apache
    restart: always
        networks:
      vlan11_ext_net:
        ipv4_address:  192.168.11.6
      internal:   
    volumes:
      - ./nextcloud:/var/www/html
    environment:
      - MYSQL_HOST=db
      - REDIS_HOST=redis
    env_file:
      - db.env
    depends_on:
      - db
      - redis

  cron:
    image: nextcloud:apache
    restart: always
    volumes:
      - ./nextcloud:/var/www/html
    entrypoint: /cron.sh
    depends_on:
      - db
      - redis

volumes:
  db:
  nextcloud:

networks:
  vlan11_ext_net:
    external: true
  internal:
    driver: bridge

i do have NGINX PRoxy Manager in front of NC, hosted on separate dmz vlan.

Do you see any issue with my config file?

the error i am getting is when i hit my IP is:


Warning: Redis::connect(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /var/www/html/lib/private/RedisFactory.php on line 124

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/lib/private/RedisFactory.php:124) in /var/www/html/lib/private/legacy/OC_Template.php on line 349

ideally this is what i am trying to accomplish is:

i feel i am so close …but so far away, this docker compose is working perfectly (so far). Just need to be able to use specific IP address instead of a port:

version: '3'

services:
  db:
    image: mariadb:10.5
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    restart: always
    volumes:
      - ./nextcloud_db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=securepassword
    env_file:
      - db.env

  redis:
    image: redis:alpine
    restart: always

  app:
    image: nextcloud:22.2.3-apache
    restart: always
    ports:
      - 8085:80
    volumes:
      - ./nextcloud:/var/www/html
      - ./data:/var/www/html/data # the actual data of NextCloud
      - ./config:/var/www/html/config #local configuration
      - ./custom_apps:/var/www/html/custom_apps # installed and custom apps
    environment:
      - MYSQL_HOST=db
      - REDIS_HOST=redis
      - APACHE_DISABLE_REWRITE_IP=1
      - TRUSTED_PROXIES=192.168.14.2/32
      - VIRTUAL_HOST=cloud.domain.com
      - NEXTCLOUD_TRUSTED_DOMAINS=domain.com


    env_file:
      - db.env
    depends_on:
      - db
      - redis

  cron:
    image: nextcloud:apache
    restart: always
    volumes:
      - nextcloud:/var/www/html
    entrypoint: /cron.sh
    depends_on:
      - db
      - redis
