Deploying Heapster on Kubernetes ARM

The YAML file below is a template you can use to deploy Heapster on a Kubernetes cluster running on ARM.

Note this is a quick setup to get Heapster deployed on a Kubernetes ARM cluster. You probably want to review the InfluxDB and Grafana setup as you might want to share that with other services. The template uses emptyDir for both the InfluxDB and Grafana storage which you might want to customize.
