The overall goal here is to waypoint install into a Nomad node from the outside. In my case, a Vagrant machine from my laptop, but also should work with other cases like cloud vendors where the waypoint-server service needs to be given a public IP, to which the install procedure connects after job submission.

For example, using a meta.public_ip that I set manually in my Nomad client config:

$ ./waypoint install -accept-tos \
  -platform=nomad \
  -nomad-host-volume=waypoint \
  -nomad-runner-host-volume=waypoint \
  -nomad-service-provider=nomad \             
  -nomad-service-address='${meta.public_ip}' \
  -nomad-network-mode=bridge

✓ Waypoint server ready
...
✓ Runner "static" adopted successfully.
Waypoint server successfully installed and configured!
...
Advertise Address: 192.168.56.200:9701
Web UI Address: https://192.168.56.200:9702/

Of course -nomad-service-address=192.168.56.200 would have worked just as well, but the meta is for demonstration, as I imagine that on AWS one might use '${attr.unique.platform.aws.public-ipv4}' to set the service address dynamically.

The ~publicly-routable IP at the bottom of the install output (and used during install) comes from the Nomad services:

$ nomad service info waypoint-server
Job ID           Address              Tags        Node ID   Alloc ID
waypoint-server  192.168.56.200:9701  [waypoint]  f8ffd891  57e5dcfd
$ nomad service info waypoint-ui
Job ID           Address              Tags        Node ID   Alloc ID
waypoint-server  192.168.56.200:9702  [waypoint]  f8ffd891  57e5dcfd

I do wonder though if perhaps separate service(s) could/should be made for this connection during install, vs internal waypoint->waypoint communication? Do the runner(s) connect to waypoint-server using this service? I didn't look that far into this part.
