2. 下载安装脚本kubekey

复制代码

[root@operation-k8s-test kubesphere]# wget https://github.com/kubesphere/kubekey/releases/download/v3.1.11/kubekey-v3.1.11-linux-amd64.tar.gz

下载完，解压压缩包

复制代码

[root@operation-k8s-test kubesphere]# ll
-rwxr-xr-x  1 root root 84046978 Aug 19 01:06 kk
-rw-r--r--  1 root root 38518611 Dec  3 17:33 kubekey-v3.1.11-linux-amd64.tar.gz

3. 创建配置

复制代码

./kk create config  --with-kubernetes v1.24.1   --with-kubesphere v3.4.1

自动生成配置文件config-sample.yaml，修改配置文件，修改后完整文件如下：

4. 部署k8s集群和KubeSphere

复制代码

[root@operation-k8s-test kubesphere]# export KKZONE=cn
[root@operation-k8s-test kubesphere]# ./kk create cluster  -f  config-sample.yaml  --with-kubernetes v1.24.1   --with-kubesphere v3.4.1

5. 部署后验证

5.1 KubeSphere登录验证

复制代码

NOTES:
Thank you for choosing KubeSphere Helm Chart.

Please be patient and wait for several seconds for the KubeSphere deployment to complete.

1. Wait for Deployment Completion

    Confirm that all KubeSphere components are running by executing the following command:

    kubectl get pods -n kubesphere-system
2. Access the KubeSphere Console

    Once the deployment is complete, you can access the KubeSphere console using the following URL:

    http://10.10.14.222:30880

3. Login to KubeSphere Console

    Use the following credentials to log in:

    Account: admin
    Password: P@88w0rd
