kubernetes - 无法通过 helm over kubernetes 安装 nginx

问题描述

我有 kubernetes Cluster v1.10 over centos 7 ，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

解决方案

Helmkubectl apply -f用于创建或更新资源，另一方面，可以称为 Kubernetes 包管理器。您发布的解决方案是一种解决方法，因为问题是关于 Helm 而不是如何使用kubectl apply. 添加--set rbac.create=false表示您可能部署了不支持 RBAC 的 Tiller。问题是，这是故意的吗？如果您没有开启 RBAC 授权，您可以继续使用--set rbac.create=false；如果要启用 RBAC，则必须添加 Tiller 服务帐户cluster-admin角色。

您可以在此处找到如何正确配置它。

有关 Helm 和 Tiller 的安装和配置的更多信息，请参见此处，以及在此 Github issue中对类似案例的详细说明。
