Not able to start kafka in local machine

I have downloaded kafka 2.4.0 binaries for Windows. When I start kafka from command line using kafka-server-start.bat using server.properties file, I get the following errors :

[2020-02-04 15:37:33,775] WARN [Controller id=0, targetBrokerId=0] Connection to node 0 (host.docker.internal/10.177.172.141:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)

From the Zookeeper logs I get these errors :

[2020-02-04 15:37:23,056] INFO Client attempting to establish new session at /127.0.0.1:51457 (org.apache.zookeeper.server.ZooKeeperServer)

I have docker installed, but it is not running. The server.properties file is untouched. I am not able to understand and debug why it is connecting to "host.docker.internal".

Note : Kafka ran successfully once. I remember I did a force shutdown of windows when kafka was running. I do not know whether this can be the issue. I tried the lower version of kafka, I am still getting the same error.

Windows Hosts file was not looking good to me.

  • I uninstalled Docker.
  • Removed all entries of "host.docker.internal", "gateway.docker.internal", "kubernetes.docker.internal".
  • Restarted my system and Kafka was running properly.

why it is connecting to "host.docker.internal

Most likely, your Windows Hosts file has been updated with that property.

You need to edit your server.properties to use 

listeners=PLAINTEXT://0.0.0.0:9092
advertised.listeners=PLAINTEXT://127.0.0.1:9092
