使用kubeKey安装k8s+kubesphere

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

   1
   export KKZONE=cn

2. 下载kubeKey

   1
   curl -sfL https://get-kk.kubesphere.io | VERSION=v1.2.1 sh -

3. 添加可执行权限

   1
   chmod +x kk

3.创建集群#

1. 创建配置文件

   1
   ./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)

3. 持久化存储配置-待研究 暂时默认(OpenEBS)

4. 安装集群

   1
   ./kk create cluster -f config-sample.yaml

5. 查看 KubeSphere 安装日志

   1
   kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
