In questo caso web\_only e data sono container separati e l’avvio del container web\_only fallisce con

```plaintext
root@docker2:/var/discourse# ./launcher start web_only
x86_64 arch detected.

starting up existing container
+ /usr/bin/docker start web_only
Error response from daemon: Cannot link to a non running container: /data AS /web_only/data
Error: failed to start containers: web_only

```

Forse in questo caso devo avviare manualmente tramite docker poiché il database è esterno su un’altra macchina, vedi questo codice nello yaml di web\_only:

```plaintext
 ## connect to central postgres database
  DISCOURSE_DB_SOCKET: ''
  DISCOURSE_DB_USERNAME: discourse
  DISCOURSE_DB_PASSWORD: xxxxxxxxxx
  DISCOURSE_DB_HOST: 10.10.xx.xx
  DISCOURSE_REDIS_HOST: data

```
