Your dashboard is up and running. You can access it by executing this command on you workstation:
kubectl --server=https://130.211.115.230/ --insecure-skip-tls-verify --username=admin --password=opYOctdphtqIBZWE proxyThereafter http://127.0.0.1/ui
Btw, anyone in the world can go do this as you accidently leaked the credentials.
Try this:
kubectl proxy --port=8001 --kubeconfig=<path-to-kubeconfig>and then go to 127.0.0.1:8001/ui.
You can skip the kubeconfig if your kubectl context is correctly set.
This is been rectified by starting the proxy. Below is the command
kubectl proxyand below is the command output. After wards I am able to access the UI.
Starting to serve on 127.0.0.1:8001
Thanks for all your contributions.
How have you installed Kubernetes on Ubuntu? If it is with kubeadm it enables RBAC by default with prevents unprivileged access to the cluster. You need to explicitly grant dashboard access to resources.
As mentioned at https://github.com/kubernetes/dashboard#deployment create the dashboard using the following command which will also setup the RBAC rules:
$ kubectl create -f https://git.io/kube-dashboardCreate the dashboard as follow kubectl create -f https://rawgit.com/kubernetes/dashboard/master/src/deploy/kuber netes-dashboard.yaml
View the username and password by running kubectl config view
Access the Dashboard as folow https://<kubernetes-master>/ui, where <kubernetes-master> is IP address or domain name of the Kubernetes master
This is a screen shot of the Dashboard I just setup from steps above
