 This default configuration is packaged in the Kafka tarball.

 Using Environment Variables

-One limitation of the environment variables approach it that you need to set all properties required to start the KRaft node.

+When using the environment variables, you need to set all properties required to start the KRaft node.
+Therefore, the recommended way to use environment variables is via Docker Compose, which allows users to set all the properties that are needed.
 It is also possible to use the input file to have a common set of configurations, and then override specific node properties using the environment variables.
 
 - Kafka property defined via environment variables will override the value of that property defined in the user provided property file.
