    # 1.初始化集群
    kubeadm reset
    kubeadm init --kubernetes-version=v1.10.1 --pod-network-cidr=10.244.0.0/16

    # 可选
    echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> /etc/profile
    source /etc/profile
    echo $KUBECONFIG    #应该返回/etc/kubernetes/admin.conf

    # 部署flannel网络
    kubectl apply -f /opt/kubernetes-1.10/kube-flannel.yml

    # 查看所有pod状态
    kubectl get pod --all-namespaces
       
    # 2.集群中增加节点
    kubeadm reset
    kubeadm join 192.168.30.11:6443 --token wtp7pf.rp8wb7p7iu15xsfk --discovery-token-ca-cert-hash sha256:7376232a605a09726675497ab969b3792028ce92fb528714f57b01543adedf46

    # 6.helm安装
      curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get | bash
      如果安装失败,则单独下载helm-v2.12.3-linux-amd64.tar.gz 并执行安装:
      tar -zxvf helm-v2.12.3-linux-amd64.tar.gzz
      mv linux-amd64/helm /usr/local/bin/helm
     
    # helm 的 bash 命令补全脚本,方法如下
        helm completion bash > .helmrc
        echo "source .helmrc" >> .bashrc
        source .bashrc
        
    # 7 安装Tiller服务器

    # 初始化权限
    ·    kubectl create serviceaccount --namespace kube-system tiller
        kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
        kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'

        # node节点上启动httpd容器
        docker run -d -p 8080:80 -v /opt/helm_repo:/usr/local/apache2/htdocs/ httpd
        
        # 打包mychart(/opt/helm/myrepo)
        helm package mycharts
        
        # 生成仓库的index文件
        mkdir myrepo
        mv mychart-0.1.0.tgz /myrepo/
        helm repo index myrepo/ --url http://192.168.30.12:8080/charts

         scp *.* root@192.168.30.12:/opt/helm_repo/charts
        
        # 通过helm repo add 将新仓库添加到Helm
        helm repo add newrepo http://192.168.30.12:8080/charts
