Kubernetes : Enable Dashboard

Enable Dashboard to manage Kubernetes Cluster on Web UI. In this example, a Kubernetes cluster is configured using four nodes as follows. +----------------------+ +----------------------+ | [ ctrl.srv.world ] | | [ dlp.srv.world ] | | Manager Node | | Control Plane | +-----------+----------+ +-----------+----------+ eth0|10.0.0.25 eth0|10.0.0.30 | | ------------+--------------------------+----------- | | eth0|10.0.0.51 eth0|10.0.0.52 +-----------+----------+ +-----------+----------+ | [ node01.srv.world ] | | [ node02.srv.world ] | | Worker Node#1 | | Worker Node#2 | +----------------------+ +----------------------+

[1]	Install Helm, refer to here.
[2]	Enable Dashboard.

debian@ctrl:~$  helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/ "kubernetes-dashboard" has been added to your repositories debian@ctrl:~$  helm install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --create-namespace --namespace kubernetes-dashboard NAME: kubernetes-dashboard LAST DEPLOYED: Fri Aug 22 19:56:00 2025 NAMESPACE: kubernetes-dashboard STATUS: deployed REVISION: 1 TEST SUITE: None NOTES: ************************************************************************************************* *** PLEASE BE PATIENT: Kubernetes Dashboard may need a few minutes to get up and become ready *** ************************************************************************************************* Congratulations! You have just installed Kubernetes Dashboard in your cluster. To access Dashboard run: kubectl -n kubernetes-dashboard port-forward svc/kubernetes-dashboard-kong-proxy 8443:443 NOTE: In case port-forward command does not work, make sure that kong service name is correct. Check the services in Kubernetes Dashboard namespace using: kubectl -n kubernetes-dashboard get svc Dashboard will be available at: https://localhost:8443 debian@ctrl:~$  kubectl get pods -n kubernetes-dashboard NAME READY STATUS RESTARTS AGE kubernetes-dashboard-api-668b9569d-xzjmp 1/1 Running 0 46s kubernetes-dashboard-auth-78c6bc6d94-jlh5w 1/1 Running 0 46s kubernetes-dashboard-kong-648658d45f-k5lrm 1/1 Running 0 46s kubernetes-dashboard-metrics-scraper-547874fcf-g9lw8 1/1 Running 0 46s kubernetes-dashboard-web-7796b9fbbb-bfwk7 1/1 Running 0 46s

[3]	Add a service account for the dashboard and configure it to have access to the dashboard.

debian@ctrl:~$  kubectl create serviceaccount -n kubernetes-dashboard dashboard-admin serviceaccount/dashboard-admin created debian@ctrl:~$  vi rbac.yml # create new apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: dashboard-admin roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-admin subjects: - kind: ServiceAccount name: dashboard-admin namespace: kubernetes-dashboard debian@ctrl:~$  kubectl apply -f rbac.yml clusterrolebinding.rbac.authorization.k8s.io/dashboard-admin created # get security token of the account above debian@ctrl:~$  kubectl -n kubernetes-dashboard create token dashboard-admin eyJhbGciOiJSUzI1NiIsI..... # set port-forwarding to access to dashboard debian@ctrl:~$  kubectl port-forward -n kubernetes-dashboard svc/kubernetes-dashboard-kong-proxy --address 0.0.0.0 8443:443 Forwarding from 0.0.0.0:8443 -> 8443
