使用kubeKey多节点安装k8s+kubesphere

以下内容均参考kubesphere官网

1.准备主机(略)

2.下载kubeKey

1. 如果网络不能访问GitHub,务必执行下面的命令

   export KKZONE=cn
   

2. 下载kubeKey

   curl -sfL https://get-kk.kubesphere.io | VERSION=v1.2.1 sh -
   

3. 添加可执行权限

   chmod +x kk
   

3.创建集群

1. 创建配置文件

   ./kk create config --with-kubesphere v3.2.1 --with-kubernetes v1.21.5 -f config-sample.yaml
   

2. 编辑调整配置文件-以下内容来自官网(仅供参考)

   #vi ~/config-sample.yaml

   kind: Cluster
   metadata:
     name: config-sample

   ···
   # 其它配置可以在安装后之后根据需要进行修改
   

3. 持久化存储配置-待研究 暂时默认(OpenEBS)

4. 安装集群

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

5. 查看 KubeSphere 安装日志

   kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
