编译安装Kubernetes 1.29 高可用集群(7)--Metrics Server节点监控配置

1.部署Metrics Server节点监控

1.1 在任意k8s-master节点上下载Metrics Server的创建文件

https://github.com/kubernetes-sigs/metrics-server/releases

wget https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.7.1/components.yaml

1.2 修改单机版配置文件

sed -i "s#10250#10350#g" components.yaml
sed -i "s#registry.k8s.io/metrics-server/#registry.aliyuncs.com/google_containers/#g" components.yaml

# 144行
args:
        - --cert-dir=/tmp
		- --secure-port=10350
        - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
        - --kubelet-use-node-status-port
        - --metric-resolution=15s  在此行下添加
        - --kubelet-insecure-tls
        - --requestheader-client-ca-file=/etc/kubernetes/pki/ca.pem
        - --requestheader-username-headers=X-Remote-User
        - --requestheader-group-headers=X-Remote-Group
        - --requestheader-extra-headers-prefix=X-Remote-Extra-

# 191行
        volumeMounts:
        - mountPath: /tmp
          name: tmp-dir  在此行下添加
        - name: ca-ssl
          mountPath: /etc/kubernetes/pki

# 200行
      volumes:
      - emptyDir: {}
        name: tmp-dir  在此行下添加
      - name: ca-ssl
        hostPath:
          path: /etc/kubernetes/pki

1.3 在任意k8s-master节点应用Metrics Server的components.yaml文件

# kubectl create -f components.yaml
serviceaccount/metrics-server created
clusterrole.rbac.authorization.k8s.io/system:aggregated-metrics-reader created
clusterrole.rbac.authorization.k8s.io/system:metrics-server created
rolebinding.rbac.authorization.k8s.io/metrics-server-auth-reader created
clusterrolebinding.rbac.authorization.k8s.io/metrics-server:system:auth-delegator created
clusterrolebinding.rbac.authorization.k8s.io/system:metrics-server created
service/metrics-server created
deployment.apps/metrics-server created
apiservice.apiregistration.k8s.io/v1beta1.metrics.k8s.io created

# kubectl get pods -n kube-system | grep metrics
