# Purpose: a minimal image holding iperf3 and ping, so that the single-machine path of
#          this lab can run the same measurement procedure between two containers that
#          the multi-machine path runs between two machines
# Platform: all (spark, strix, nvidia with Docker Engine; Track M with Docker Desktop
#           or Podman). The base image is multi-architecture, so it builds on aarch64.
# Minimum memory: 8 GB
# Assumes: nothing but a working container runtime and a network connection to fetch
#          the packages once. Built by compose.yaml; there is no reason to build it
#          by hand.
