搭建kubernetes高可用集群(三)

4. 检查集群状态相干指令

4.1 查看node

kubectl get nodes -o wide

4.2 检查Pod

kubectl -n kube-system get pod -o wide

效果图

4.3 查看service

kubectl -n kube-system get svc

4.4 验证IPVS

kubectl -n kube-system logs -f <kube-proxy 容器名>

效果图

4.5 查看代理规则

ipvsadm -ln

4.6 查看生效配置

kubectl -n kube-system get cm kubeadm-config -oyaml

4.7 查看etcd集群

kubectl -n kube-system exec etcd-kubernetes-master-150 -- etcdctl \
	--endpoints=https://192.168.10.150:2379 \
	--ca-file=/etc/kubernetes/pki/etcd/ca.crt \
	--cert-file=/etc/kubernetes/pki/etcd/server.crt \
	--key-file=/etc/kubernetes/pki/etcd/server.key cluster-health
# 输出如下
member 6778ae6450f78ed5 is healthy: got healthy result from https://192.168.10.150:2379
member b09baf5ea972fb33 is healthy: got healthy result from https://192.168.10.152:2379
member f6e19b81305c201a is healthy: got healthy result from https://192.168.10.151:2379
cluster is healthy

4.8 检查VIP存在于那一台主机

ip a |grep ens33
