New install, `Connection to node 1005 (/172.19.0.2:64289) could not be established. Broker may not be available`

[jspc]

Starting kafka via:

$ docker-compose up

Gives me the above error, after:

1. Cloning the repo from fresh
2. Changing the line KAFKA_ADVERTISED_HOST_NAME: 192.168.99.100 to HOSTNAME_COMMAND: "ip a | grep inet | grep -v 127 | awk '{print $$2}' | awk -F/ '{print $$1}'"

(I've pasted a patch to this issue to show precisely what I have done)

My use case is pretty simple- I have a series of containers I want to access kafka. They will attach to the network that docker-compose creates (kafka-docker_default by default), and access kafka through there, by using kafka-docker_kafka_1 as the initial broker.

Is this not possible? Is there a smarter way to accomplish what I want to accomplish? I've verified inside the container that this command correctly returns the correct IP address.

I note that if I set KAFKA_ADVERTISED_HOST_NAME to the IP 172.19.0.2 specifically (and get lucky on containers starting in the correct order, getting the correct address, and some other reason I don't follow) then the logs are clear and everything works as I want it to.

Am I misunderstanding the docs? Does HOSTNAME_COMMAND not do what i'm trying to get it to do?

did you ever find a fix for this?

[dibericky]

Are there any news about this?

[RichardMM]

use confluent's kafka image...works right out of the box. @dibericky

This image also works out of the box if the listeners are used instead of advertised host/port
