# A Kafka broker and a Confluent-compatible schema registry for the sample: Redpanda, one container.
#   docker compose up -d --wait     start it, and wait until it is healthy
#   docker compose down             stop and remove it
# Kafka is at 127.0.0.1:19092 and the schema registry at http://127.0.0.1:18081 (IPv4: Docker on Windows doesn't
# forward the ports on IPv6, where "localhost" resolves first).
