How to setup Kubernetes Dashboard in EKS using NodePort?

Step 1: Deploy the Dashboard
# Deploy the Kubernetes dashboard to your cluster:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

# Deploy heapster to enable container cluster monitoring and performance analysis on your cluster:

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/heapster.yaml

# Deploy the influxdb backend for heapster to your cluster:

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/influxdb.yaml

# Create the heapster cluster role binding for the dashboard:

$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/rbac/heapster-rbac.yaml

Step 2: Create an eks-admin Service Account and Cluster Role Binding
# Create a file called eks-admin-service-account.yaml with the text below:

vi eks-admin-service-account.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: eks-admin
  namespace: kube-system

$ kubectl apply -f eks-admin-service-account.yaml

vi eks-admin-cluster-role-binding.yaml

apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: eks-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: eks-admin
  namespace: kube-system

$ kubectl apply -f eks-admin-cluster-role-binding.yaml

Step 3: Retrieve an authentication token
Retrieve an authentication token for the eks-admin service account. Copy the <authentication_token> value from the output. You use this token to connect to the dashboard.

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep eks-admin | awk '{print $1}')

Step 4: Connect to the Dashboard Via Node Port
Retrieve an authentication token for the eks-admin service account. Copy the <authentication_token> value from the output. You use this token to connect to the dashboard.

$ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep eks-admin | awk '{print $1}')
$ kubectl get pods --all-namespaces
$ kubectl get pods --namespace=kube-system
$ kubectl get svc --all-namespaces

$ kubectl edit svc/kubernetes-dashboard --namespace=kube-system
or
$ kubectl -n kube-system edit service kubernetes-dashboard
Just change "type: NodePort" only

# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
#
apiVersion: v1
kind: Service
metadata:
  creationTimestamp: 2018-07-27T10:22:50Z
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
  resourceVersion: "3288196"
  selfLink: /api/v1/namespaces/kube-system/services/kubernetes-dashboard
  uid: 03f2f747-9187-11e8-9432-02b761c0deac
spec:
  clusterIP: 10.100.194.75
  externalTrafficPolicy: Cluster
  ports:
  - nodePort: 30530
    port: 443
    protocol: TCP
    targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  sessionAffinity: None
  type: NodePort
status:
  loadBalancer: {}

$ kubectl describe pods kubernetes-dashboard-7d5dcdb6d9-mt9b9 --namespace=kube-system 
#Find which node is running and get a Port of SVC

$ kubectl get svc --all-namespaces
$ kubectl get pods --all-namespaces
$ kubectl describe pods kubernetes-dashboard-7d5dcdb6d9-h9dcb --namespace=kube-system

Step 5: Connect to the Dashboard Via ClustorIP and Proxy
http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

https://10.16.39.28:30178/

IMPORTANT – Kubernetes Dashboard should be HTTPS
