# Multi-stage build for OpenMessaging Benchmark (OMB).
# The published openmessaging/openmessaging-benchmark:latest image ships
# Kafka client 1.0.0 on Java 8.  This Containerfile builds from the
# current upstream source (Kafka 3.6.1, JDK 21).

# Upstream OMB has no tags or releases — pin to a known-good commit on master.
