加载命名空间时出错。未经授权：验证您有权访问 Kubernetes 集群

Question

我已经使用命令行 eksctl 创建了一个 EKS 集群，并验证了该应用程序运行正常。

但是注意到一个奇怪的问题，当我尝试在 Web 浏览器中访问集群中的节点时，我看到以下错误

Error loading Namespaces
Unauthorized: Verify you have access to the Kubernetes cluster

我能够看到节点使用 kubectl get nodes

我以管理员用户身份登录。关于如何解决这个问题的任何帮助都会非常好。谢谢。

Answer 1

您需要将您的 IAM 角色/用户添加到集群的 aws-auth 配置映射

从https://docs.aws.amazon.com/eks/latest/userguide/add-user-role.html采取的基本步骤

kubectl edit -n kube-system configmap/aws-auth

# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
