kubernetes - 无法通过Kubernetes使用Helm安装Nginx

Question

我在centos 7上有kubernetes Cluster v1.10，裸机

helm version
Client: &version.Version{SemVer:"v2.11.0-rc.3", GitCommit:"28d295be2a94115b786ee277dffcc2b5483bde47", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.11.0-rc.3", GitCommit:"28d295be2a94115b786ee277dffcc2b5483bde47", GitTreeState:"clean"}

我正在尝试使用Helm安装Nginx

helm install stable/nginx-ingress --name nginx

它返回

Error: release nginx failed:

我该如何解决这个问题？

谢谢:D

另一方面，由于kubectl apply -f用于创建或更新资源，因此Helm可以称为Kubernetes Package Manager。您发布的解决方案是一种解决方法，因为该问题与Helm有关，而不是与如何使用kubectl apply创建资源有关。添加--set rbac.create=false表示您可能部署了不支持RBAC的Tiller。问题是，是否有意进行？如果您尚未开启RBAC授权，则可以继续使用--set rbac.create=false；如果要启用RBAC，则必须为Tiller服务帐户添加cluster-admin角色。

您可以找到如何正确配置它here.

可以在here上获得有关Helm and Tiller的安装和配置的更多信息，以及此Github issue中类似情况的详细说明。
