  # just in case we've already run docker compose up before, we do a hard reset on the cluster to remove any configuration or saved
  # topology data that might have changed between `docker compose up` runs; you can also do a `--force-recreate` with your `docker
  # compose run` to just recreate everything and not worry about anything persisting; we also fire the hard resets off at the same
  # time to try and avoid nodes gossiping stale state to each other
  #
  # we then create the cluster after giving the nodes time to stabilize (the first 30s sleep); after cluster creation, we
  # sleep for another 30s to get through synchronization with enough time to spare for clearing past failures
  #
  # finally, we set the announced hostname to something useable outside of docker so the test binaries can reach it
  #
  # NOTE: you might see a bunch of connection errors across `docker compose run`s because containers might come up with different
  # internal networking (in particular, different IPs for the services) but redis will hold on to cluster info (that's the
  # working theory, it might be wrong)
