URL: https://github.com/apache/incubator-heron/pull/3741#issuecomment-982156778
**_Phase 2_**
- [x] Load Pod Templates via `heron.kubernetes.[executor |
manager].pod.template=[ConfigMap].[Pod Template]`
- [x] Configure Persistent Volumes via `heron.kubernetes.[executor |
manager].volumes.persistentVolumeClaim.[Volume Name].[Option]=[Value]`
- [x] Configure resources for the `manager` and/or `executor` via
`heron.kubernetes.[executor | manager].[limits | requests].[Option]=[Value]`
Please note that the commands have changed to load Pod Templates and PVCs
and as such the docs are now mostly obsolete.
