Federico Valeri updated KAFKA-17953:
------------------------------------
Description:
When running the docker image with an env var, you get the following error:
{code}
$ docker run --rm -it -p 9092:9092 \
-e KAFKA_NUM_NETWORK_THREADS=4 \
apache/kafka:3.8.1
...
Exception in thread "main" org.apache.kafka.common.config.ConfigException:
Missing required configuration `zookeeper.connect` which has no default value.
at kafka.server.KafkaConfig.validateValues(KafkaConfig.scala:1232) at
kafka.server.KafkaConfig.<init>(KafkaConfig.scala:1223) at
kafka.server.KafkaConfig.<init>(KafkaConfig.scala:545) at
kafka.tools.StorageTool$.$anonfun$execute$1(StorageTool.scala:72) at
scala.Option.flatMap(Option.scala:283) at
kafka.tools.StorageTool$.execute(StorageTool.scala:72) at
kafka.tools.StorageTool$.main(StorageTool.scala:53) at
kafka.docker.KafkaDockerWrapper$.main(KafkaDockerWrapper.scala:48) at
kafka.docker.KafkaDockerWrapper.main(KafkaDockerWrapper.scala)
{code}
The KafkaDockerWrapper does not copy the default KRaft config before appending
the user env vars as an override.
The result is that you end up with a server.properties that contains only the
env vars.

{code}
In this case, the KafkaDockerWrapper setup does not copy the default KRaft
config before appending the user env vars. Basically, it expects the whole
configuration as env vars, rather than appending to default KRaft config.
