I have set up both Metabase and Druid from my Mac Docker machine.
However, when I try to connect by pointing to the IP addresss of the docker container (it is the same IP address), and use the defaul 8082 port to the Druid broker, I am unable to connect.
We should be able to connect to anything the process running the jvm can see. There shouldn’t be anything special so long as a connection opened to the ip + port of the druid cluster are accessible from the other docker container.
You should double check your port mappings.
