How to Run the Kubernetes Dashboard Locally

Kubernetes comes with a pretty nice dashboard to view clusters, worker groups, nodes and pods. As well as a ton of other useful things.

This tutorial presumes that you already have a Kubernetes cluster setup and running and have access to it through kubectl in your command-line.

Steps to run Kubernetes Dashboard

Start by downloading the metrics-server and applying it to your kubectl config.

DOWNLOAD_URL=$(curl -Ls "https://api.github.com/repos/kubernetes-sigs/metrics-server/releases/latest" | jq -r .tarball_url)
DOWNLOAD_VERSION=$(grep -o '[^/v]*$' <<< $DOWNLOAD_URL)
curl -Ls $DOWNLOAD_URL -o metrics-server-$DOWNLOAD_VERSION.tar.gz
mkdir metrics-server-$DOWNLOAD_VERSION
tar -xzf metrics-server-$DOWNLOAD_VERSION.tar.gz --directory metrics-server-$DOWNLOAD_VERSION --strip-components 1
kubectl apply -f metrics-server-$DOWNLOAD_VERSION/deploy/1.8+/

Next, we will start setting up the metrics-server, ready for action!

kubectl get deployment metrics-server -n kube-system

Now apply the recommended configuration directly to your local kubectl:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml

At this stage, we need to create a eks-admin-service-account.yaml. Once you have done this, put the following code in the newly created file:

apiVersion: v1
kind: ServiceAccount
metadata:
  name: eks-admin
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: eks-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: eks-admin
  namespace: kube-system

We are now able to apply this configuration to our local kubectl:

kubectl apply -f eks-admin-service-account.yaml

Next, we will need to query the system to get an authorization token which we will use to login to the dashboard:

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep eks-admin | awk '{print $1}')

This command will print out a whole bunch of stuff. It will look something like this:

Name:         eks-admin-token-hdwhb
Namespace:    kube-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: eks-admin
              kubernetes.io/service-account.uid: adf46a76-5e04-11ea-b83c-0a643b334a90

Type:  kubernetes.io/service-account-token

Finally, we can run the proxy command to serve the dashboard via HTTP:

kubectl proxy

How to view the dashboard

The dashboard is now available at the following location:

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#!/login

You will then be presented with this screen:

Sign into Kubernetes Dashboard

This is where we will select “Token” and paste in our token that was just given to us in the command-line:

Sign into Kubernetes Dashboard

Click “Sign in” and you’re ready to roll!
