1、查看etcd的2381端口
[root@master-node manifests]# netstat -anp|grep 2381 tcp 0 0 127.0.0.1:2381 0.0.0.0:* LISTEN 21765/etcd
2、获取etcd的pod
[root@master-node manifests]# kubectl get pod -A NAMESPACE NAME READY STATUS RESTARTS AGE cattle-system cattle-cluster-agent-7f9549666f-vmxg4 0/1 Error 316 28h kube-system coredns-6d56c8448f-q4z57 1/1 Running 19 2d4h kube-system coredns-6d56c8448f-zfkq6 1/1 Running 20 2d4h kube-system etcd-master-node 1/1 Running 0 13m kube-system kube-apiserver-master-node 1/1 Running 19 2d4h kube-system kube-controller-manager-master-node 1/1 Running 140 2d4h kube-system kube-flannel-ds-676v4 1/1 Running 1 2d4h kube-system kube-flannel-ds-7jgt4 0/1 Error 345 47h kube-system kube-proxy-bplzt 1/1 Running 3 2d4h kube-system kube-proxy-dlg4d 1/1 Running 1 47h kube-system kube-scheduler-master-node
3、查看etcd的pod详细信息
[root@master-node manifests]# kubectl describe pod etcd-master-node -n kube-system Name: etcd-master-node Namespace: kube-system Priority: 2000001000 Priority Class Name: system-node-critical Node: master-node/192.168.0.122 Start Time: Wed, 08 Nov 2023 12:21:48 +0800 Labels: component=etcd tier=control-plane Annotations: kubeadm.kubernetes.io/etcd.advertise-client-urls: https://192.168.0.122:2379 kubernetes.io/config.hash: 38ea1142faa6b3f8c460f84403b98231 kubernetes.io/config.mirror: 38ea1142faa6b3f8c460f84403b98231 kubernetes.io/config.seen: 2023-11-10T16:19:05.396386513+08:00 kubernetes.io/config.source: file Status: Running IP: 192.168.0.122 IPs: IP: 192.168.0.122 Controlled By: Node/master-node Containers: etcd: Container ID: docker://4e1937cde08ee05e572d9e3b4e39e1fa44c5f9113dec93f21c4f616ae244dd60 Image: registry.aliyuncs.com/google_containers/etcd:3.4.13-0 Image ID: docker-pullable://registry.aliyuncs.com/google_containers/etcd@sha256:4ad90a11b55313b182afc186b9876c8e891531b8db4c9bf1541953021618d0e2 Port: <none> Host Port: <none> Command: etcd --advertise-client-urls=https://192.168.0.122:2379 --cert-file=/etc/kubernetes/pki/etcd/server.crt --client-cert-auth=true --data-dir=/var/lib/etcd --initial-advertise-peer-urls=https://192.168.0.122:2380 --initial-cluster=master-node=https://192.168.0.122:2380 --key-file=/etc/kubernetes/pki/etcd/server.key --listen-client-urls=https://127.0.0.1:2379,https://192.168.0.122:2379 --listen-metrics-urls=http://127.0.0.1:2381 --listen-peer-urls=https://192.168.0.122:2380 --name=master-node --peer-cert-file=/etc/kubernetes/pki/etcd/peer.crt --peer-client-cert-auth=true --peer-key-file=/etc/kubernetes/pki/etcd/peer.key --peer-trusted-ca-file=/etc/kubernetes/pki/etcd/ca.crt --snapshot-count=10000 --trusted-ca-file=/etc/kubernetes/pki/etcd/ca.crt State: Running Started: Fri, 10 Nov 2023 16:19:35 +0800 Ready: True Restart Count: 0 Liveness: http-get http://127.0.0.1:2381/health delay=10s timeout=15s period=10s #success=1 #failure=8 Startup: http-get http://127.0.0.1:2381/health delay=10s timeout=15s period=10s #success=1 #failure=24 Environment: <none> Mounts: /etc/kubernetes/pki/etcd from etcd-certs (rw) /var/lib/etcd from etcd-data (rw) Conditions: Type Status Initialized True Ready True ContainersReady True PodScheduled True Volumes: etcd-certs: Type: HostPath (bare host directory volume) Path: /etc/kubernetes/pki/etcd HostPathType: DirectoryOrCreate etcd-data: Type: HostPath (bare host directory volume) Path: /var/lib/etcd HostPathType: DirectoryOrCreate QoS Class: BestEffort Node-Selectors: <none> Tolerations: :NoExecuteop=Exists Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Pulled 9m47s kubelet Container image "registry.aliyuncs.com/google_containers/etcd:3.4.13-0" already present on machine Normal Created 9m47s kubelet Created container etcd Normal Started 9m46s kubelet Started container etcd
4、编辑etcd.yaml
vi /etc/kubernetes/manifests/etcd.yaml
5、验证
