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.
