官方文档： https://github.com/kubernetes/helm/blob/master/docs/rbac.md

1. 编写 helm_rbac-config.yaml 文件 ：

   apiVersion: v1
   kind: ServiceAccount
   metadata:
     name: tiller
   
     namespace: kube-system
   ---
   
   apiVersion: rbac.authorization.k8s.io/v1beta1
   kind: ClusterRoleBinding
   metadata:
     name: tiller
   roleRef:
     apiGroup: rbac.authorization.k8s.io
     kind: ClusterRole
     name: cluster-admin
   subjects:
     - kind: ServiceAccount
       name: tiller
       namespace: kube-system

2. 执行脚本

   kubectl apply -f helm_rbac-config.yaml

安装 tiller

1. 执行脚本

   helm init --service-account=tiller --stable-repo-url=http://kubernetes-charts.storage.googleapis.com

   成功会显示：

   Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.
   
   Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.
   For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation
   Happy Helming!

2. 更新 repo

   helm repo update
   sed -i 's/https/http/g' ~/.helm/repository/cache/stable-index.yaml

3. 验证 helm 安装是否成功

   helm version

   正常会显示：

   Client: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}
   Server: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}

4. 验证 repo 是否正常

   helm search redis

   正常会显示：
