I have a kafka server in my local host, and i want to connect it in my docker container.

I had searched how to connect local services in docker container and i found this: how-to-connect-to-local-mysql-server-through-docker

But it didn't work. Please help me, thanks~

  • Attention!!! I want to connect to my local host kafka brokers not in another docker container. – koma Feb 14 '17 at 09:00
  • I do not u nderstand when you say "I have a kafka server in my local host, and i want to connect it in my docker container." – user2915097 Feb 14 '17 at 09:07
  • please, clarify - what is run on container? does Kafka running on your local host, and you have another app running inside the docker on same host? – evgenyl Feb 14 '17 at 15:16
  • @evgenyl yes, the docker container also running in my local host and i want my app running in the docker container could connect to the kafka that running in my local host. – koma Feb 15 '17 at 02:33

Try updating kafka config as shown below 

$ nano config/server.properties

uncomment listeners and paste the following

listeners=PLAINTEXT://<local-ip>:9092

save file & restart kafka.

Hope this helps!

In my Kafka server.properties I had advertised.listeners=PLAINTEXT://localhost:9092. This only allow access via localhost. Once I changed it to my machine's IP address everything worked fine.

If I understand right, you question can be re-phrased as "How can I access my host machine withing my docker container".

As i wrote in another answer, you can set gateway when starting your container, create some kind of proxy to access your Kafka or take the host ip from container.
