[ekneg54]

• Rewrite quickstart setup:
  • Remove logstash, replace elasticsearch by opensearch and use logprep opensearch connector to stick to reference architecture
  • Use kafka without zookeeper and switch to bitnami container images

Opensearch ✔️ looks good, as you removed opensearch security completely for this test deployment, which is legitimate for this purpose, there is nothing that is missing that would otherwise do

Kafka ❌ As I pointed out in the comment, for Kafka there seems to be missing a Environment Variable. I don't know if I did something wrong or maybe this requirement was baked into the image recently but it won't run this way on my machine.

indeed they come with a newer version the last days. I fixed the NODE ID issue and pinned the kafka version to ensure, this never happens again.

[herrfeder]

the logprep config doesn't resolve correctly because of the mounting path in logprep container

please see my suggestion for the readme change in my commit in this branch.

thx for your commit. I removed zookeeper from readme too as the point for this simplification was to remove zookeeper from the configuration
