In this blog we will see how to install Kubernetes Dashboard in Kubernetes cluster.

Kubernetes dashboard is a web ui console, Users can manage/view applications which is running in Kubernetes cluster and troubleshoot them.


Kubernetes cluster

Step 1:

Install kubernetes dashboard,

# kubectl apply -f

Using the latest version.

check the pods status for kubernetes dashboard.

# kubectl get pods -n kubernetes-dashboard

Step 2:

Kubernetes dashboard access,

Make the dashboard accessible outside by changing the network type to NodePort

# kubectl get svc -n kubernetes-dashboard

# kubetcl edit svc kubernetes-dashboard  -n kubernetes-dashboard

Now got the port number to access the kubernetes dashboard.

URL : https://kubernetes-IP:PortNo.

eg :

Step 4:

Token Generation,

Create cluster admin service account:

To login kubrnetes dashboard we need to create a service account by using below commands to create it and get the token.

# kubectl create serviceaccount admin-user

# kubectl create clusterrolebinding admin-user --clusterrole=cluster-admin --serviceaccount=default:admin-user

Next, get the token.

# kubectl get secret|grep admin-user

# kubectl describe secret admin-user-token-hglv9

Now copy token from the second command and enter in the Kubernetes dashboard by choosing token.


To create a limited access service account will allow to access only pods.

# vi pod-access.yaml

kind: ClusterRole
  name: pod-access
- apiGroups: [""] # core API group
  resources: ["pods", "namespaces"]
  verbs: ["get", "watch", "list"]

save and close the file.

# kubectl create serviceaccount pod-access

# kubectl apply -f pod-access.yaml

# kubectl create clusterrolebinding pod-access --clusterrole=pod-access --serviceaccount=default:pod-access

# kubectl get secret

# kubectl describe secret pod-access-token-kx2jc

Now use this token in kubernetes dashboard which will has access to only pods.

That's all, Kubernetes dashboard has been installed successfully and created admin and limited access service accounts to login dashboard.
