I'm using kafka-node to send messages between the services in my application. I'm using the wurstmeister/kafka and wurstmeister/zookeeper containers to run Kafka and Zookeeper (for simplicity's sake).
Every time I try to send() a message to the broker, I get a LeaderNotAvailable error. I used kafka-web-console to inspect the broker, and it shows the two topics that I had set up, but it shows no leader (see http://cl.ly/image/1f3g0K2S1J0F).
Neither from reading the container logs (below), nor any documentation, nor trying to search for this problem can I work out why it's not working (or how to fix it).
Update sending seems to work if I destroy the containers and start them up again (rather than just restarting them using docker-compose up).
