4.type in token in kubernetes-dashboard-token-xxxxx secret

What exactly have you done in this step? You should copy one of secrets' token.

I typed in the token of kubernetes-dashboard-token-jn7tx

I edit kubernetes-dashboard service,change the service type from ClusterIP to NodePort,and access dashboard with the ip and port instead of the proxy,in this case,everything is ok.

@jhcpokemon What happens after filling token and confirming it with Sign In button?

What happens after filling token and confirming it with Sign In button

Nothing happend,and no error in the chrome console.

Nothing happend,and no error in the chrome console.

This can only happen if you are exposing Dashboard using kubectl proxy and trying to access it from other machine, not using localhost or 127.0.0.1 as domain.

[jhcpokemon]

Yes,I run the kubernetes cluster in my centos 7 virtual machine,and access the dashboard with the vm's IP,like this 192.168.189.129:9090/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login

[floreks]

Then this is the real reason. Your initial description was misleading:

3.goto
http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

Logging in is only available when accessing Dashboard over HTTPS or when domain is either localhost or 127.0.0.1. It's done this way for security reasons. Closing as this works as intended.

It is mentioned in our documentation:

NOTE: Dashboard should not be exposed publicly using kubectl proxy command as it only allows HTTP connection. For domains other than localhost and 127.0.0.1 it will not be possible to sign in. Nothing will happen after clicking Sign in button on login page.

@floreks I exposed the dashboard publicly which is running on my CentOS VM and can't sign in as it is over HTTP. How do I expose the dashboard over HTTPS ?
