To reproduce:

Creating a cluster with kubekey

Step 1:Download KubeKey v1.2.0 and add permission.

curl -sfL https://get-kk.kubesphere.io | VERSION=v1.2.0 sh -
chmod +x kk

Step 2:Create configuration file for cluster

./kk create config

Step 3:Modify config-sample.yaml include hosts and kubernetes.version

apiVersion: kubekey.kubesphere.io/v1alpha1
kind: Cluster
metadata:
  name: config-sample
spec:
  - {name: node1, address: 192.168.6.5, internalAddress: 192.168.6.5, user: root, password: Qcloud@123}
  - {name: node2, address: 192.168.6.6, internalAddress: 192.168.6.6, user: root, password: Qcloud@123}
  - {name: node3, address: 192.168.6.7, internalAddress: 192.168.6.7, user: root, password: Qcloud@123}
  roleGroups:
    etcd:
    - node1
    - node2
    - node3
    master: 
    - node1
    - node2
    - node3
    worker:
    - node1
    - node2
    - node3
  controlPlaneEndpoint:
    internalLoadbalancer: haproxy
    
    domain: lb.kubesphere.local
    address: ""
    port: "6443"
  kubernetes:
    version: v1.21.5

Step 4:Get Started With Installation It's recommended to install using root user, then create a cluster using the configuration file:

./kk create cluster -f config-sample.yaml
