# - 'acme': ACME server to replace the real servers at Let's Encrypt.
# - 'dnsserver': The pebble challenge test server so we can use a private DNS
# for everything here.
# - 'VPS': The Pangolin instance, running Gerbil, Traefik, and Badger as well.
# - 'privateHost': The private server running an HTTP server on its local
# network that will be tunnelled via Newt to the VPS.
# - 'client': An outside node that will test if the service hosted in
# 'privateHost' is publicly accessible.
# TODO: In the future, we should also have a machine to test the
# functionality of Olm, as well as a split Pangolin/Gerbil
# configuration once that is implemented into the module.
