As your cluster is RBAC-enabled, by default the pod that runs the dashboard has a minimal role bound to its service account: If you want to make sure the Kubernetes dashboard can access all the resources in the cluster, you can simply create a ClusterRoleBinding object to bind the cluster-admin role to the service account that runs the Kubernetes dashboard pod, using the following command: Once this command applied, just hit refresh in your browser and you should have a Kubernetes dashboard up and running with no access error messages anymore: OK, this is great. By default, the service is only available internally to the cluster (ClusterIP) but changing to NodePort exposes the service to the outside. 2. We hope you enjoy monitoring your cloud native applications with Prometheus and Grafana! You need to decide what virtual machines (or bare metal hardware) you need for the control plane servers . Setting the service type to NodePort allows all IPs (inside or outside of) the cluster to access the service. When there are Kubernetes objects defined in the cluster, Dashboard shows them in the initial view.
