Error log on controller manager: Failed to reconcile hello-world: failed to compute desired number of replicas based on CPU utilization for Deployment/default/hello-world: failed to get CPU utilization: failed to get CPU consumption and request: metrics obtained for 0/3 of pods
I can talk directly to Heapster and get my pod metrics: curl http://$MY_HEAPSTER_SERVICE_IP:8082/api/v1/model/namespaces/default/pods//hello-world-819237062-j0ubt/metrics/cpu-usage
{
"metrics": [
{
"timestamp": "2016-04-05T16:49:00Z",
"value": 0
},
{
"timestamp": "2016-04-05T16:48:00Z",
"value": 0
}
],
"latestTimestamp": "2016-04-05T16:49:00Z"
}
As explained in the comment above the Heapster was running in a non-default location, which horizontal pod autoscaler controller did not expect.
I've opened an issue to make it configurable.
