> This looks great. Did we need to make two services? Or did the single
headless service match on the pods from both StatefulSet instances?
I used just the single `Service` to match the Pods and I am trying to check
on the topology to make sure it is actually working correctly. I will try to
bring up the Minikube deployments using the Helm chart to check and make sure.
Thank you for the information on bringing up the UI.
> Should we also allow for setting both the request and limit values for
manager cpu and memory?
Done. I will configure `requests` to be set to `limits` if there are
`limits` provided but no `requests`.
```bash
~/bin/heron submit kubernetes ~/.heron/examples/heron-api-examples.jar \
--verbose \
--deploy-deactivated \
