Replace deprecated Bitnami Kafka image to ensure Makefiles and scripts keep working

[igor-soldev]

Hi,

I noticed that the local development setup (Docker Compose, Makefiles, and helper scripts) relies on bitnami/kafka:2.

The Problem

1. Access Restrictions: Bitnami has restricted public access to their images, which can lead to pull access denied errors for contributors.
2. Hardcoded Paths: Your Makefile and scripts/produce_* files execute commands inside the container using specific paths like:
   /opt/bitnami/kafka/bin/kafka-topics.sh
/opt/bitnami/kafka/bin/kafka-console-producer.sh

Switching to a standard image (like apache/kafka) would break these scripts because the binary paths would be different.

Proposed Solution
I suggest switching to soldevelo/kafka:2 (or a newer version if you prefer).
This image is a drop-in replacement that preserves the /opt/bitnami/... directory structure. This means your Makefiles and helper scripts will continue to work immediately without needing to rewrite all the paths.

Suggested Change
Update docker-compose.yml and cmd/ziggurat/templates/docker-compose.yml.tpl:

# Old
image: 'bitnami/kafka:2'

# New
image: 'soldevelo/kafka:2'

Affected files:

• docker-compose.yml
• cmd/ziggurat/templates/docker-compose.yml.tpl
• (Indirectly benefits Makefile and scripts/* by keeping them valid)

I can submit a PR to update the image reference. Would you be open to that?
