We also have a timing issue when new clusters are created where the kubedashboard is not available immediately after cluster-create. We're working on providing better status/messaging in this window of time. Typically if you see this shortly after a cluster create, you may just need to wait a few minutes for the dashboard to be started.

There was an IBM Cloud incident that affected IBM Cloud Kubernetes Service management functions, including kube dashboard access. This issue has been resolved.

The outage is posted here: https://console.bluemix.net/status/notification/877c340fb941bc8c72211c513763c077

The source of this information is here. And here you can find the information about access tokens for Kubernetes dashboard.

Check if you are still able to connect to Kubernetes dashboard in the following ways:

kubectl proxy:

Check if your kubectl is properly configured and has access to the cluster.

`$ kubectl cluster-info 
Kubernetes master is running at ...
...`

Start local proxy server:

$ kubectl proxy

Use the following address to access dashboard:

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

API Server:

If you are able to communicate with the cluster apiserver right from your workstation, you can access the dashboard by following this link:

https://<master-ip>:<apiserver-port>/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

The apiserver port is 6443 by default.

Ingress:

You can expose a dashboard port using an Ingress resource.
