Kafka on Docker cannot connect from other container

Hi I’m using Spotify/Kafka and am running it with

docker run —name ka -p 9092:9092 -p 2181:2181 —env ADVERTISED_HOST=localhost —env ADVERTISED_PORT 2181 —net mynet spotify/kafka

I make sure I run my second container using the same net and I can ping the Kafka container using ka.mynet

Also in this second container I downloaded kafka and it’s shell scripts and I’m able to do a

./kafka-topics.sh —zookeeper ka.mynet —list and see the “Test” topic

Now any attempt to produce or consume spits out errors. Producer complains about something to do with not finding a leader.

Other Googling has led me to believe it has something to do with the advertised host.

Ok it seems like the only way to get this to work is to assign my machine's current IP address as the ADVERTISED_HOST env variable.

So if my machine's IP is 192.168.1.11 then:

docker run —name ka -p 9092:9092 -p 2181:2181 —env ADVERTISED_HOST=192.168.1.11 —env ADVERTISED_PORT=9092 —net mynet spotify/kafka
