# ksqlDB Server LOCAL single-node stack, using confluentinc images.
# This Compose is mostly taken from https://ksqldb.io/quickstart.html#quickstart-content it includes 
#   - Zookeper and a Kafka broker for the basic Kafka setup
#   - Schema Registry for AVRO/Protobuff schema support
#   - ksqldb-server for the ksqlDB server, using the local Dockerfile
#   - akhq for the Kafka UI 
#   - ksqlDB-cli integrated, you can use it with `docker exec -it ksqldb-cli ksql http://ksqldb-server:8088`
# 
# if you want to use ksqldb-cli outside of compose, use `host.docker.internal:8088` as the server address.
