# Kafka docker setup

Seems like there is a behavior change between 7.4.4 and latest (7.8.0, too) images. The same config works for 7.4.4 but not for the latest (it tries to connect broker and it fails).

28.12.2024 - last 7.4.x tag 7.4.8 version seems to be working well.
Needs to be checked what's the difference between 7.4.8 and 7.5.0

28.12.2024 - migrated to apache/kafka:latest and zookeeper:latest but kafka version needs to be synchronized with the client ones.
             Switch it to 3.9.0 at least.
