As per Kubernetes documentation, "Dashboard is a web-based Kubernetes user interface. You can use Dashboard to deploy containerized applications to a Kubernetes cluster, troubleshoot your containerized application, and manage the cluster resources".
You can install Dashboard by executing a single command which is available in the Kubernetes documentation. We do not provide the command for Dashboard installation here, because it depends on the Dashboard version number. Please refer to the the Kubernetes documentation for the installation and user creation instructions.
