I'm new to docker and now I want to use `docker-compose`. I would like to provide the `docker-compose.yml` script the config file with host/port, maybe credentials and other cassandra configuration. 

[***DockerHub link.***](https://hub.docker.com/r/bitnami/cassandra/)

How to specify it in the compose script:

```
cassandra:
  image: bitnami/cassandra:latest

```
