kubeadm init --apiserver-advertise-address=192.168.254.129 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.24.3 --service-cidr=10.96.0.0/12 --pod-network-cidr=10.244.0.0/16

集群状态检测

查看所有nod节点

1	kubectl get no

查看node的信息

1	kubectl describe nodes node1

查看指定空间内所有Pod

1	kubectl get po -n kube-system

查看Pod的信息

1	kubectl describe po kube-proxy-np9bz -n kube-system

删除Pod

1	kubectl delete po kube-proxy-dmbqw -n kube-system

查看容器的日志

1	kubectl logs kube-proxy-dmbqw -n kube-system

查看命令空间

kubernetes在集群启动之后，会默认创建几个namespace

1	kubectl get ns

查看service的信息

1	kubectl get service
