Docker-compose tutorial updates?

I'm trying to test out Cachet with docker-compose following this link: `https://docs.cachethq.io/docs/get-started-with-docker`

so far:
- last version of cachet (2.3.18) not working since the command called `:install` does not exists
- using the version as is in the guide i get this error
```
