Hi I am using kafka ui with below compose file but almost every time it shows cluster down, even though it is up. Can u check what might be the issue here.

Using compose file as below:

Hi @akashdktyagi, thank you for creating this issue. Looks like some bug happing during cluster init, which cause incorrect status message. We'll check and fix it in nearest releases.

Hi @germanosin,

I am facing the same issue. Please find below my Docker compose file for reference. I hope it helps.

Hi, @agwermann I tried to run your docker-compose and everything looks good for me, could you try with latest version?

      - KAFKA_CLUSTERS_0_ZOOKEEPER=zookeeper:2181

Any idea when a fix would be available?

Hi, @tomaytotomato I tried your docker compose. I see that you are exposing 2 advertised listeners: kafka:19092 and 127.0.0.1:9092 Kafka UI is working inside kafka docker network. I can not connect to 127.0.0.1:9092, that's why you have to pass kafka:19092 address for. So after changing config to

   kafka-ui:
     image: provectuslabs/kafka-ui
     container_name: kafka-ui
     ports:
       - "8081:8080"
     restart: always
     depends_on:
       - kafka
       - zookeeper
     environment:
       - KAFKA_CLUSTERS_0_NAME=local
       - KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS=kafka:19092
       - KAFKA_CLUSTERS_0_ZOOKEEPER=zookeeper:2181

Everything works fine
