Kubernetes Dashboard :

Dashboard is a web-based Kubernetes user interface. You can use Dashboard to deploy containerized applications to a Kubernetes cluster, troubleshoot your containerized application,

• Setting up the dash board:

$ kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml

• Create user to access dashboard. We will create user using RABC for default namespace access.

Create RABC yaml and apply it.

apiVersion: v1

kind: ServiceAccount

metadata:

  name: admin-user

  namespace: default

---

apiVersion: rbac.authorization.k8s.io/v1

kind: ClusterRoleBinding

metadata:

  name: admin-user

roleRef:

  apiGroup: rbac.authorization.k8s.io

  kind: ClusterRole

  name: cluster-admin
