Hi,

my nextcloud instance is showing that cron is not working. I added a cron container but it is not working. Does anyone has an idea what is wrong with my setup?

version: '3' 

services:

  proxy:
    image: jwilder/nginx-proxy:alpine
    labels:
      - "com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy=true"
    container_name: nextcloud-proxy

      - nextcloud_network
    ports:
      - 80:80
      - 443:443

    restart: unless-stopped

  cron:
   image: nextcloud:apache
   container_name: nextcloud-cron
   networks:
     - nextcloud_network
   depends_on:
     - db

     - nextcloud:/var/www/html
   entrypoint: /cron.sh
   restart: unless-stopped

volumes:
  nextcloud:

Any hint is more than welcome.

in your cron: container you should map all volumes you mapped into your app: container

additionally I would recommend to use same image (:latest is now same as :apache but who knows what happens in the future).

I would recommend against using :latest tag but rather use dedicated version flags

Hi wwe,

thanks for the tip. I changed the config and now it seems to work?

New config:

  cron:
   image: nextcloud:latest
   container_name: nextcloud-cron
   networks:
     - nextcloud_network
   depends_on:
     - db
     - proxy
   volumes:
     - nextcloud:/var/www/html
     - ./app/config:/var/www/html/config
     - ./app/custom_apps:/var/www/html/custom_apps
     - ./app/data:/var/www/html/data
     - ./app/themes:/var/www/html/themes
     - /etc/localtime:/etc/localtime:ro
   entrypoint: /cron.sh
   restart: always

As an alternative, you can call cron.php via docker exec from the host’s cron.
