          To create an external IP address called `myip` that corresponds to the internal IP address `165.87.54.14` that belongs to the private cloud `my-private-cloud` in project `my-project` and location `us-east2-b`, run:

            $ {command} myip --project=my-project --private-cloud=my-private-cloud --location=us-east2-b --internal-ip=165.87.54.14 --description="A short description for the new external address"

            $ {command} myip --private-cloud=my-private-cloud --internal-ip=165.87.54.14 --description="A short description for the new external address"

          In the second example, the project and region are taken from gcloud properties core/project and vmware/region.
