1. recommend.yaml 다운로드

 

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

 

2. yaml 파일 수정

 

nano recommend.yaml

 

NodePort 를 이용해서 dashboard 포트를 지정할 계획

'- nodePort: 사용할 포트번호' 와  'type: NodePort' 를 아래처럼 추가

 

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  ports:
  - nodePort: 31000 # 수정
    port: 443
    protocol: TCP
    targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  type: NodePort # 수정

 

3. deploy

 

kubectl apply -f recommend.yaml

 

4. pod 확인

 

kubectl get po -n kubernetes-dashboard

 

5. admin 계정 생성 (dashboard-admin.yaml 생성)

 

---
apiVersion: v1
kind: ServiceAccount
metadata:
   name: admin-user
   namespace: kubernetes-dashboard
---
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

 

6. token 생성

 

kubectl -n kubernetes-dashboard create token admin-user

kubectl -n kubernetes-dashboard delete serviceaccount admin-user
kubectl -n kubernetes-dashboard delete clusterrolebinding admin-user
