Replace Bitnami Legacy Kafka image in docker-compose

[igor-soldev]

Description

I noticed that the docker-compose file used for test/docker-compose.yml utilizes the bitnamilegacy/kafka:3.9 image.

Proposed Solution

I suggest replacing the Kafka image with a free, compatible alternative: soldevelo/kafka:3.9.

The soldevelo image is designed as a drop-in replacement for Bitnami. It:

1. Tracks upstream Kafka versions.
2. Preserves the /opt/bitnami/... directory structure.
3. Fully supports the KAFKA_CFG_ environment variables used in your current configuration.

This ensures that the existing kafka service definition in docker-compose will continue to work without needing to rewrite the environment variables or volume definitions.

Changes

• Update image in the kafka service within docker-compose.

If this aligns with the project's needs, I am happy to submit a Pull Request with this update.

Hi team, just a quick follow-up.

Since this affects the test environment, relying on the legacy image creates unnecessary friction for contributors trying to run the suite locally. Switching to the maintained alternative resolves this instantly without requiring config changes.

Would you be open to a PR?

Thanks for flagging this — you're right that the bitnamilegacy images are outdated and need to be replaced.

However, for our test infrastructure we prefer to stick with well-established, widely-used images. We'll likely switch to the official Apache Kafka image (apache/kafka) or update the Docker setup as part of the ongoing Kafka transporter migration (#1336).

Closing this for now, but appreciate the heads-up!
