Nextcloud Docker - how to connect to MariaDB

docker

#1

Hi all. I want to run Nextcloud Docker containers on my Cloud-Server. Space is a bit limited here for me, and as I expect that the NC Data and it’s databese will get quite big over time, I want to put those files on an NFS share of my storrage-system.

In oder to achieve this, I altered the docker-compose.yaml to this:

version: '2'

volumes:
  nextcloud:
  db:

services:
  db:
    image: mariadb
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    restart: always
    volumes:
      - /data/nextcloud/db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=****************
      - MYSQL_PASSWORD=****************
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

  app:
    image: nextcloud
    ports:
      - 8080:80
    links:
      - db
    volumes:
      - /data/nextcloud/files:/var/www/html
    restart: always

So far, Nextcloud starts up and giving me the installation wizard page where I need to enter the MariaDB credentials.

But all attemps to connect to the db have failed so far.

Failed to connect to the database: An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused 

So given the config above … what do I have to put in the field: “Database Host” to connect to the DB ?
