Kafka access inside and outside docker

Question

Answer 1

Your config of the listeners looks correct, the problem is with your Docker Compose:

ports:
  - "9094:9092"

You’re mapping 9094 (‘Outside’) back to 9092 (‘Inside’) and thus when you connect you’re connecting to the ‘Inside’ listener. If you remove this line of config then your listener set up should work as intended.
