Question

我在裸机centos 7上拥有kubernetes Cluster v1.10

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"}

我正在尝试使用头盔安装nginx

helm install stable/nginx-ingress --name nginx

返回

我该如何解决这个问题？

谢谢：D

Answer 1

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表示您可能在没有RBAC支持的情况下部署了Tiller。问题是，是否故意进行？如果您尚未打开RBAC授权，则可以继续使用--set rbac.create=false;如果要启用RBAC，则必须添加Tiller服务帐户cluster-admin角色。

您可以找到如何正确配置它here.

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

OR

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

无法在Kubernetes上通过使用头盔安装nginx
