Determine actual Kafka version that is being used inside confluentinc/cp-kafka:6.2.2 image. #915

Closed MUsman1992 closed 2 years ago

I want to determine the exact version of Kafka inside confluentinc/cp-kafka:6.2.2 image. On this site, https://docs.confluent.io/platform/current/installation/versions-interoperability.html#cp-and-apache-ak-compatibility I have read that inside image with tag 6.2.x kafka version 2.8.x is being used but I want to determine the exact version of kafka. I want to know whether the exact version is 2.8.1 or 2.8.0. I also went inside this folder inside docker container /usr/share/java/kafka but could not determine the exact version of the kafka. The files of this folder can be viewed in the below diagram.

Can anyone guide me in this regard. Thanks

I answered a similar question on Stackoverflow

Note: This repo no longer deploys the kafka container images

There is no "exact version" mapping between apache/kafka and confluent/kafka (Confluent Community Server) except for the initial .0 release. As in CP 6.2.0 will ship with something that is very close to AK 2.8.0. After the .0 release there is no direct mapping, as confluent will put out releases on a different cadence than that of apache/kafka.

Instead you can look at the CP tags (v6.2.2) in https://github.com/confluentinc/kafka to get a rough idea of where/how that relates too apache/kafka 2.8.x
