无法使用helm over kubernetes安装nginx

Question

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

它回来了

我该如何解决这个问题？

谢谢你：D

Answer 1

由于kubectl apply -f用于创建或更新资源，另一方面，Helm可以称为Kubernetes Package Manager。 您发布的解决方案是一个解决方法，因为问题是关于Helm而不是如何使用kubectl apply创建资源。 添加--set rbac.create=false表示您可能在没有RBAC支持的情况下部署了Tiller。 问题是，它是故意做的吗？ 如果您没有打开RBAC授权，则可以继续使用--set rbac.create=false ; 如果您想要启用RBAC，则必须将Tiller服务帐户添加为cluster-admin角色。

您可以在此处找到如何正确配置它。

Answer 2

搜索后，我认为这是解决方案

helm install stable/nginx-ingress --name ingress --namespace kube-system --set rbac.create=false --set rbac.createRole=false --set rbac.createClusterRole=false

要么

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/cloud-generic.yaml
