Running docker test env with Confluent docker quickstart

[sshanks-kx]

When using this env
https://docs.confluent.io/current/quickstart/ce-docker-quickstart.html

Add doc to detail how to get a kdb q instance to talk to the above env (given that the above is setup to communicate with each other inside the env)

[sshanks-kx]

Run the above env.
After start-up, can run

docker network ls
docker network inspect cp-all-in-one_default

to see the new network configured & hosts running within it

When running a separate docker image containing kdb/Kafka libs, in order to talk to the above network add the following to your docker run cmd
--network cp-all-in-one_default
That your container within the same network so it can talk to the hosts with broker/zookeeper/etc.

Then your docker image needs to use
broker:29092
as the broker to connect to.

NOTE: when running your own docker container, if you need to open another shell to it, can run the likes of ...
docker exec -it <docker container name> /bin/bash
