---------------------------------------
Summary: KIP-500 Setup and named docker volumes
Key: KAFKA-13171
URL: https://issues.apache.org/jira/browse/KAFKA-13171
Project: Kafka
Issue Type: Improvement
Affects Versions: 2.8.0
Reporter: Claudio Carcaci
Following the KIP-500 instructions to enable the Kraft mode
([https://github.com/apache/kafka/blob/trunk/config/kraft/README.md)] the
command:
{code:java}
$ ./bin/kafka-storage.sh format -t <uuid> -c ./config/kraft/server.properties
{code}
will create a "meta.properties" file in the logs folder (i.e.
/tmp/kraft-combined-logs).
If I build a Docker image with Kraft mode enabled and I mount a named volume on
the /tmp/kraft-combined-logs the content of the folder will be overwritten
(emptied) by the Docker named volume content. So I will lose the
meta.properties file.
A possible solution would be to create the meta.properties file in a separated
folder and store all the created logs elsewhere so that by mounting a named
volume the logs folder can start empty.
