URL: https://github.com/apache/incubator-heron/pull/3741#issuecomment-981192284
**_Phase 2_**
- [x] Load Pod Templates via `heron.kubernetes.[executor |
manager].pod.template=[ConfigMap].[Pod Template]`
- [ ] Configure Persistent Volumes via `heron.kubernetes.[executor |
manager].volumes.persistentVolumeClaim.[Volume Name].[Option]=[Value]`
- [ ] Configure resources for the `manager` via
`heron.kubernetes.manager.[limits | requests].[Option]=[Value]`
Individual Pod Template loading for the `Executor`s and `Manager` is now
complete. Please note that the commands have changed to load Pod Templates and
that the old Pod Template docs are now mostly obsolete. On the TODO list is
individual PVC and resource CLI commands.
