{
  "kind": "Endpoints",
  "apiVersion": "v1",
  "metadata": {
    "name": "example-external-service" 
  },
  "subsets": [ 
    "api.mysaas.com:80",
    "api2.mysaas.com:8080"
  ]

Comment 10 Josep 'Pep' Turro Mauri 2017-04-24 09:47:22 UTC 
The ExternalName service type that covers this use case was released with OCP 3.5:

https://docs.openshift.com/container-platform/latest/release_notes/ocp_3_5_release_notes.html#ocp-35-ability-to-refer-to-external-endpoints-by-name

However, it seems there are no specific docs about it beyond that mention in the release notes, so I'm moving this to a documentation bug to address that.
