【问题描述】:
kubectl version
Client Version: version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.0", GitCommit:"5cb86ee022267586db386f62781338b0483733b3", GitTreeState:"clean"}
Server Version: version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.0", GitCommit:"5cb86ee022267586db386f62781338b0483733b3", GitTreeState:"clean"}
控制器管理器上的错误日志:
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
我可以直接与 Heapster 交谈并获取我的 pod 指标: 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"
}

查看控制器管理器代码后,我能够找出导致此故障的原因。控制器管理器被硬编码以查找名称为“heapster”和“kube-system”命名空间中的 heapster 服务。我的服务未命名为 heapster,因此控制器管理器无法与之通信。
