[question] service stanza inside task cannot find port labels

[m1keil]

I'm having issues making this trivial config to execute:

(Nomad 0.12.7)

job "example" {
  datacenters = ["dc1"]
  group "webGroup" {
    network {
      port "http" { to = 80 }
    }
    task "webTask" {
      driver = "docker"
      config {
        image = "nginxdemos/hello"
        ports = ["http"]
      }
      service {
        port = "http"
        check {
          type     = "tcp"
          interval = "10s"
          timeout  = "2s"
          port     = "http"
        }
      }
      resources {
        cpu    = 500
        memory = 256
      }
    }
  }
}

Getting back:

Error submitting job: Unexpected response code: 500 (1 error occurred:
	* Task group webGroup validation failed: 1 error occurred:
	* Task webTask validation failed: 1 error occurred:
	* 1 error occurred:
	* port label "http" referenced by services example-webGroup-webTask does not exist

After fiddling around with it I realized that moving the service stanza up into the task group does the trick.
I can't understand or find the relevant reference in the docs to why this doesn't work in the first place. This doc seems to have exact same config.

This seems to be a duplicate of #8780

It is indeed. Thank you.
