# =============================================================================
# Local test harness: render a small SeaweedFS cluster with the core module
# and run it as real `weed` processes on 127.0.0.1 (no cloud, no docker).
#
# 3 masters (quorum) + 1 volume + 1 filer + 1 standalone S3, each on a distinct
# port. run_local_cluster.sh consumes the `cluster` output, launches the weed
# processes from the rendered argv, and asserts the cluster actually works.
