2. 给helm创建rbac的授权

student@ubuntu:~/helm/linux-amd64$kubectl create serviceaccount --namespace kube-system tiller

student@ubuntu:~/helm/linux-amd64$kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller

3.部署tiller服务器

 helm init -i ist0ne/tiller --service-account tiller

4.查看部署状态

student@ubuntu:~/helm/linux-amd64$helm version
Client: &version.Version{SemVer:"v2.7.0", GitCommit:"08c1144f5eb3e3b636d9775617287cc26e53dba4", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.7.2", GitCommit:"8478fb4fc723885b155c924d1c8c410b7a9444e6", GitTreeState:"clean"}
