Kubernetes is great, but it is mostly command line and YAML manifests. Kubernetes Dashboard is an easy way to visualize every nook and cranny of your Kubernetes Cluster, let’s take a look at how to install it.

Prerequisites

Important
I take absolutely NO responsibility of what you do with your machine; use this tutorial as a guide and remember you can possibly cause data loss if you touch things carelessly.

I will assume you have:

  • A functioning Kubernetes cluster (Don’t have one? Check this tutorial for starters.)
  • You have installed kubectl on your machine.
  • You have configured kubectl to communicate with your cluster.

Installing Kubernetes Dashboard is surprisingly easy:

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

After a few minutes you will have a functioning dashboard, but how to access it? Firstly do:

$ kubectl proxy

This will create a secure tunnel between you and your Kubernetes cluster. You can now access the dashboard through this address: http://localhost:8001/api/v1/namespaces/kube-system/services/kubernetes-dashboard:/proxy/.

How to access Kuberntes Dashboard

If you have RBAC set up in your cluster, chances are you will face the screen above.

In this case you will need a Bearer Token to access the Dashboard. To get it you can use the following oneliner:

$ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep kubernetes-dashboard-token | awk '{print $1}') | grep 'token:' | awk -F " " '{print $2}'

In case you get a list of multiple strings, you don’t have a secret named “kubernetes-dashboard-token”, meaning you haven’t installed the dashboard correctly.
