安装Kubernetes

详情参考：https://www.kubesphere.io/zh/docs/v4.1/03-installation-and-upgrade/02-install-kubesphere/02-install-kubernetes-and-kubesphere/

  • 安装依赖项
    sudo apt install socat conntrack ebtables ipset -y

  • 下载kubekey

          export KKZONE=cn
      curl -sfL https://get-kk.kubesphere.io | sh -
      sudo chmod +x kk
  • 创建集群
    配置文件参考：https://github.com/kubesphere/kubekey/blob/master/docs/config-example.md

          registryMirrors: []
          insecureRegistries: []
        addons: []

          ./kk create config --with-kubernetes <Kubernetes version>
      ./kk create cluster -f node-k8s.yaml
      开始下载依赖的二进制、镜像和组件，都保存在当前目录的kubekey下面.
      时间较长，完成以后，执行 kubectl get pod -A 查看是否安装成功。

  • 新增节点

    编辑配置文件，将新的节点写入到配置文件中，并确定是worker还是master等。 然后执行新增命令

         ./kk add nodes -f multi-node-k8s.yaml
  • 删除节点 
         ./kk delete node node2 -f multi-node-k8s.yaml
  • 安装kubesphere
