部署dashboard

1.編寫RBAC.yaml檔案

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nginx-sa
---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: nginx-role
rules:
- apiGroups:
  - ""
  resources:
  - pods
  verbs:
  - get
  - list
  - watch
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: nginx-rolebinding
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: Role
  name: nginx-role
subjects:
- kind: ServiceAccount
  name: nginx-sa

2.檢視secret

kubectl get secret

3.檢視對應的token

kubectl describe secret nginx-sa-token-775kt

4.定義dashboard.yaml

5.應用yaml

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

6.檢視當前已有的名稱空間

kubectl get namespace

7.檢視Service的type

kubectl get service --namespace=kubernetes-dashboard

8.將Service的type修改為NodePort

kubectl --namespace=kubernetes-dashboard edit service kubernetes-dashboard

9.訪問web dashboard
