I did this for free codecamp:

```plaintext
volumes:
  - volume:
      host: /var/discourse/shared/standalone
      guest: /shared
  - volume:
      host: /var/discourse/shared/standalone/log/var-log
      guest: /var/log
  - volume:
      host: /var/postgres_data
      guest: /shared/postgres_data

```

Basically I keep `/var/postgres_data` in root and then mount `/var/discourse/shared/` on the second volume, additionally I put docker containers in `/var/discourse/shared/docker`

There are many ways of skinning this, just keep postgres\_data on the fastest drive and you should be good.
