k8s 监控程序Metric-server pod运行异常报：it doesn't contain any IP SANs

k8s 监控程序Metric-server pod运行异常：出现

metrics-server error because it doesn't contain any IP SANs

查看 pod状态，pod 正在运行 但是pod状态不正常：

kubectl get pods -n kube-system

metrics-server-756b6bb44f-d5tgj                0/1     Running   0          11s           

查看日志：

it doesn't contain any IP SANs" node="kubernetes-master"

it doesn't contain any IP SANs" node="node1

google搜索发现：

主要是通过 metric-server增加启动参数解决：

主要原因是：证书双向验证不通过，这个这里可以采取忽略处理

args:
- --cert-dir=/tmp
- --secure-port=4443
- --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
- --kubelet-use-node-status-port
- --kubelet-insecure-tls           

对应deployment.yaml文件修改内容为：

containers:
      - name: metrics-server
        image: swr.cn-east-3.myhuaweicloud.com/hll-bigdata/metrics-server:v0.5.0
        imagePullPolicy: IfNotPresent
        args:
          - --cert-dir=/tmp
          - --secure-port=443
          - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
          - --kubelet-use-node-status-port
          - --metric-resolution=15s
          - --kubelet-insecure-tls           

再执行pod状态正常

kk get pods

metrics-server-756b6bb44f-d5tgj              1/1     Running   0          16m
