Producer from another docker container unable to send/write messages to kafka topic #60

Hi,

Things work perfectly when I use a producer app I have using localhost:9092 as a broker with your container. However, when I try to run the same producer on another docker container on my machine, it's unable to talk to your container and I get the below error. Hoping you'd be able to give a suggestion on what I could try. Thanks!

"org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after 60000 ms"

It's about docker networking, read a bit about it and how you can leverage i.e. --network to define networks for dockers to talk to each other. Please re-open ticket if you can't find a solution.

Also remember that Kafka needs to advertise it's IP address correctly for other application to be able to reach it, and you can set that via the -e ADV_HOST=[VM_EXTERNAL_IP] flag when executing fast-data-dev
