I’ve created a new Kubernetes environment using some bare metal VM hosts. I am trying to get Heapster to push data into a separate Elasticsearch instance, but it is failing. I believe this is owing to an issue fixed in a later version of Heapster (https://github.com/kubernetes/heapster/pull/1607) than the one deployed by Rancher (v1.3.0-beta.1).
How can I get Rancher to use the later version?
