My Nextcloud is running in a docker container with MariaDB, and Redis in Raspberry Pi, if I’m not config the Redis in config.php, the Nextcloud will work, but if I config the config.php regarding Redis, the error below will show up( An error will be reported during file related operations
).

please help, Thanks!

my config.php about redis as below:

  'filelocking.enabled' => true,
  'memcache.locking' => '\OC\Memcache\Redis',
  'redis' => array(
     'host' => '172.17.0.3',
     'port' => 6379,
     'timeout' => 0.5,
     'dbindex' => '0',
     'password' => 'jabal123',
      ),

error logs in nextcloud as below:

hi @Tate welcome to the forum :handshake:

in docker you

  • configure the system primarily through environment variables and not through config.php
  • don’t configure an IP but rather container (service) name as redis connection as the IP will change once you restart the container.

This might or not be an issue in your case. I would recommend you docker inspect <redis> and docker inspect <nextcloud-app> and verify both are connected to the same network.

here is a very basic docker-compose extract what you need to configure redis:

cat redis.env

REDIS_HOST=redis
REDIS_HOST_PASSWORD=myhighsecurepasswordforredis

cat compose.yaml

---
version: "3.3"
  redis:
    image: redis:alpine
    container_name: nextcloud-redis
    command: redis-server --requirepass ${REDIS_HOST_PASSWORD}
    env_file:
      - ./redis.env
    restart: unless-stopped

  nextcloud-app:
    image: nextcloud:${NEXTCLOUD_VERSION}
    container_name: nextcloud-app
    depends_on:
      - db
      - redis
    env_file:
      - ./redis.env
      - ./other-related-varaibles.env
...
    networks:
      # this network is used to connect to the app e.g. from reverse proxy
      externalnetwork:
      # db and redis is connected to this network by default
      default:
...

Many thanks for your kind reply, I Ignored the network configuration of Redis, now it’s working now.
