Redis password AUTH issue in docker-compose example

[laenan8466]

We need to update this example (docker-compose/with-nginx/mariadb/fpm), to handle the redis-db password issue (#1179).

Other docker-compose examples could be affected as well.

I fixed the problem by:

1. Adding a redis.env file with:
   REDIS_HOST_PASSWORD=mypassword
2. Modifiying the docker-compose.yml file in the following sections:

  app:
    image: nextcloud:fpm-alpine
    restart: always
    volumes:
      - nextcloud:/var/www/html
    environment:
      - MYSQL_HOST=db
      - REDIS_HOST=redis
    env_file:
      - redis.env
      - db.env
    depends_on:
      - db
      - redis

  redis:
    image: redis:alpine
    restart: always
    command: /bin/sh -c "redis-server --requirepass $$REDIS_HOST_PASSWORD"
    env_file:
      - redis.env

I have not the time atm to submit a PR, but wanted to have this documented.

Thank you for documenting this -- I was able to fix up my install with this info.

How about we use a secrets file for the redis password?

[feefladder]

Also Take!

[feefladder]

But not sure if proper way is to check if password is empty or add files and everything

[padajuan]

worked, excellent!

This should be no longer necessary since #1232 was merged. However, it's possible that pre-existing deployments may need to manually update their config/redis.config.php due ot #1533.
