一、下載yaml檔案
wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml
# 國內映象
jicki/nginx-ingress-controller:0.21.0
# （國內）替換所有的 images

sed -i 's/quay\.io\/kubernetes-ingress-controller/jicki/g' *
二、匯入yaml檔案
kubectl  apply -f mandatory.yaml 

#檢視
[[email protected] yaml]# kubectl  get pods -n ingress-nginx
NAME                                        READY   STATUS    RESTARTS   AGE
nginx-ingress-controller-766c77b7d4-nn4c7   1/1     Running   0          49s

三、# 建立一個基於service和Deployment

 [
 
[email protected] yaml]# cat   ingress-deploy-demo.yaml
apiVersion: v1
kind: Service
metadata:
  name: nginx-svc
spec:
  selector: #標籤選擇
    name: nginx
  ports:
  - port: 80 #伺服器埠
    name: http #名稱
    targetPort: 80 #容器埠
    protocol: TCP #協議,預設TCP

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-nginx-deploy
spec:
  replicas: 3
  selector: 
    matchLabels:
      name: nginx
  template:

        image: nginx:alpine #映象
        ports:

          containerPort: 80 #容器埠


#匯入yaml檔案
