4 To delete a cluster
1 Create a single-node cluster k8s
1.1 Creating a cluster

# kind create cluster --name k8s-single-node-cluster

1.2 View cluster information

# export KUBECONFIG="$(kind get kubeconfig-path --name="k8s-single-node-cluster")"# kubectl cluster-info

1.3 Check cluster node information

# kubectl get nodes

1.4 Viewing Cluster Component Information

# kubectl get cs

1.5 Creating deployment and pod

# kubectl run nginx --image=nginx:1.14-alpine --replicas=2

1.6 View pod Information

2 Create k8s multi-node cluster (1 Master, 1 worker)
2.1 to prepare a multi-node cluster configuration file

# touch /opt/kind/config/k8s-multi-nodes-cluster.yaml
文件内容如下：
kind: Cluster
apiVersion: kind.sigs.k8s.io/v1alpha3
nodes:
- role: control-plane
- role: worker

2.2 Creating a multi-node cluster

# kind create cluster --config ./k8s-multi-nodes-cluster.yaml --name k8s-multi-nodes-cluster

2.3 set and get a multi-node cluster information

# export KUBECONFIG="$(kind get kubeconfig-path --name="k8s-multi-nodes-cluster")"
# kubectl cluster-info

2.4 View multi-node cluster information

# kubectl get nodes

3 Create HA HA k8s cluster (multi-master, multi-worker)
3.1 to write high-availability cluster configuration file

# touch /opt/kind/config/k8s-ha-cluster.yaml

文件内容如下：

# 一共四个节点，二个 control-plane 节点，二个 workers 节点
kind: Cluster
apiVersion: kind.sigs.k8s.io/v1alpha3

3.2 Creating High Availability Cluster

# kind create cluster --config ./k8s-ha-cluster.yaml --name k8s-ha-cluster

3.3 set and get high availability cluster information

# export KUBECONFIG="$(kind get kubeconfig-path --name="k8s-ha-cluster")"
# kubectl cluster-info

Check Availability Cluster 3.4 information

# kubectl get nodes

4 to remove a cluster

# kind delete cluster --name k8s-single-node-cluster

# unset KUBECONFIG
