Use context: kubectl config use-context k8s-c1-H
You're ask to find out following information about the cluster k8s-c1-H:
How many controlplane nodes are available? How many worker nodes are available? What is the Service CIDR? Which Networking (or CNI Plugin) is configured and where is its config file? Which suffix will static pods have that run on cluster1-node1? Write your answers into file /opt/course/14/cluster-info , structured like this:
# /opt/course/14/cluster-info

kubectl config use-context k8s-c1-H检查节点和控制节点可用数量
k get node
k desribe node | grep -i taints查看集群CIDR 及CNI 插件位置
ssh cluster1-controlplane1
root@cluster1-controlplane1:~# cat /etc/kubernetes/manifests/kube-apiserver.yaml | grep range
