Creating a ClusterRoleBinding
In most cases after provisioning cluster using kops, kubeadm or any other popular tool, the ClusterRole cluster-admin already exists in the cluster. We can use it and create only ClusterRoleBinding for our ServiceAccount. If it does not exist then you need to create this role first and grant required privileges manually.

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: kubernetes-dashboard

Issues

clusterrolebinding.rbac.authorization.k8s.io/admin-user unchanged

which prevents you from going to the next step to install kubernetes-dashboard.

Answer 1

unchanged - means that the applied manifest already corresponds to the current state. Those. ClusterRoleBinding has been created.
