Question

我需要一些帮助，以使kubernetes-dashboard与AWS ALB入口一起正常工作。我已经使用kubernetes-dashboard成功部署了helm chart，并且通过kubectl proxy或kubectl port-forward访问时，一切正常。但是，通过AWS ALB访问时，我只有一个空白屏幕。

不确定是否与此有关，但是我注意到<body><kd-root>节在通过ALB访问时为空，但是在通过其他方法（也称为端口转发）访问时为非空。我想知道我是否缺少使这一切正常工作的一些关键配置参数。

我正在使用

Kubernetes 1.18（AWS EKS）
kubernetes-dashboard 2.0.4
kubernetes-dashboard舵图2.8.1
chrome 85.0.4183.121

我正在使用NodePort服务。这是我的入口资源（由舵图创建）。

没关系，我发现了问题。我将自己的ALB规则设置为仅允许/，而不是我真正想要的/*。
