While Kubernetes provides powerful command-line tools for managing clusters, sometimes a visual interface can make monitoring and managing your deployments even easier. Kubernetes Dashboard is a web-based user interface that allows you to visualize and interact with your Kubernetes clusters. + +In this blog post, we will walk you through the process of installing and accessing Kubernetes Dashboard step-by-step, empowering you to streamline your Kubernetes management tasks. + +##### Prerequisites + +Before installing Kubernetes Dashboard, ensure that you have a running Kubernetes cluster and have the necessary administrative access. + +### Installing Kubernetes Dashboard + +The easy way to install Kubernetes dashboard for your cluster is via helm chart. Kubernetes Dashboard now has a dependency on cert-manager and nginx-ingress-controller. Fortunately, these dependencies can be automatically installed using the Helm chart. However, if you already have these components installed, you can disable their installation by setting the flags –set=nginx.enabled=false and –set=cert-manager.enabled=false when installing the chart. + +Without any further delay, let’s jump into installation steps, + +##### 1 ) Install Helm + +Access your cluster’s master node using a terminal or command prompt. Install helm if not installed. Run the following commands. + +``` +$ curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 +$ chmod 700 get_helm.sh +$ ./get_helm.sh +``` + +##### 2) Add Kubernetes Dashboard Helm Repository + +Run following helm command to add dashboard repository, + +``` +$ helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/ +$ helm repo list +``` + +##### 3) Install Kubernetes Dashboard + +To install Kubernetes dashboard using helm, run following command, + +``` +$ helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --create-namespace --namespace kubernetes-dashboard +``` + +Output above confirms dashboard has been deployed in Kubernetes-dashboard namespace. So, in order to access dashboard, run + +``` +$ kubectl -n kubernetes-dashboard port-forward svc/kubernetes-dashboard-nginx-controller 8443:443 +``` + +Now, open the web browser of system on which you have run above command, type following url + +https://localhost:8443 + +Click on “Accept the Risk and Continue” + +As you can see above, we need a token to login. So, let’s generate the required token in the next step. + +##### 4)  Generate Token for Kubernetes Dashboard + +Open one more ssh session to master node and create a service account and assign required permissions using following yaml file, + +``` +$ vi k8s-dashboard-account.yaml +apiVersion: v1 +kind: ServiceAccount +metadata: +  name: admin-user +  namespace: kube-system +--- +apiVersion: rbac.authorization.k8s.io/v1 +kind: ClusterRoleBinding +metadata: +  name: admin-user +roleRef: +  apiGroup: rbac.authorization.k8s.io +  kind: ClusterRole +  name: cluster-admin +subjects: +- kind: ServiceAccount +  name: admin-user +  namespace: kube-system +``` + +save and exit the file + +Next create service account by running following command + +``` +$ kubectl create -f k8s-dashboard-account.yaml +serviceaccount/admin-user created +clusterrolebinding.rbac.authorization.k8s.io/admin-user created +$ +``` + +Now, generate the token for admin-user, run + +``` +$ kubectl -n kube-system  create token admin-user +``` + +Copy this token and head back to browser, paste it on “Enter Token” field as shown below, + +Click on “Sign in” + +##### 5) Access Kubernetes Dashboard + +When we click on “Sign in” in above then we will get the following dashboard, + +Great, you are now logged in to the Kubernetes Dashboard. Here are a few key features and functionalities to explore: + +- Cluster Overview: Gain an overview of your cluster’s health, resource utilization, and running pods. +- Workloads: View and manage your deployments, replica sets, stateful sets, and daemon sets. +- Services: Monitor and manage your services, including load balancers and external endpoints. +- Configurations: Explore your config maps, secrets, and persistent volume claims. +- Storage: Manage persistent volumes and storage classes. +- Namespaces: Switch between namespaces to view and manage resources across different projects or teams. + +That’s all from this post, I hope you have found it useful and informative.
