需要对指标服务器部署进行一些补丁才能使指标正常工作。
请按照以下步骤操作
kubectl delete -f deploy/1.8+/
wait till the metrics server gets undeployed
run the below command
kubectl create -f https://raw.githubusercontent.com/epasham/docker-repo/master/k8s/metrics-server.yaml
master $ kubectl get po -n kube-system

检查并验证指标服务器部署清单中的以下行。
command:
- /metrics-server
- --metric-resolution=30s
- --kubelet-preferred-address-types=InternalIP
- --kubelet-insecure-tls
