Example of docker-compose

This is a simple example of how to use docker-compose to stand up cassandra, postgres, and rabbitmq as available local services

How-to and such

$ docker-compose up

then to be sure everything is kosher, open a new tab/terminal and...

$ docker ps

it should look like this:

$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS
                                                                                                       NAMES

                                                                                                       compose_postgres_1

you can also run docker-compose ps and it'll be a little easier to read, but provide less insight overall

$ docker-compose ps

Todo

• add cassandra entrypoint and other scripts for configuration of services, etc
