一、下載並修改配置檔案

1、下載整合配置檔案，獲取配置檔案地址：https://github.com/kubernetes/ingress-nginx/tree/nginx-0.20.0/deploy

2、修改配置檔案

[root@k8s-master ingress]# cat mandatory.yaml |grep image
...
# 修改defaultbackend映象地址改成阿里雲的映象地址
          image: registry.cn
 
-qingdao.aliyuncs.com/kubernetes_xingej/defaultbackend-amd64:1.5  # 1、修改映象地址為阿里雲地址
...

二、執行 Ingress 配置檔案

# 1、修改並執行配置檔案
[root@k8s-master ingress]# vi mandatory.yaml 
[root@k8s-master ingress]# kubectl apply -f mandatory.yaml 
namespace/ingress-nginx created
deployment.extensions/default-http-backend created
service
 
/default-http-backend created
configmap/nginx-configuration created
configmap/tcp-services created
configmap/udp-services created
serviceaccount/nginx-ingress-serviceaccount created
clusterrole.rbac.authorization.k8s.io/nginx-ingress-clusterrole created
role.rbac.authorization.k8s.io/nginx-ingress-role created
rolebinding.rbac.authorization.k8s.io
 
/nginx-ingress-role-nisa-binding created
clusterrolebinding.rbac.authorization.k8s.io/nginx-ingress-clusterrole-nisa-binding created
deployment.extensions/nginx-ingress-controller created

# 2、檢視執行結果
[root@k8s-master ingress]# kubectl get pods -n ingress-nginx -o wide
NAME                                        READY   STATUS    RESTARTS   AGE   IP               NODE         NOMINATED NODE   READINESS GATES
default-http-backend-5c9bb94849-9b4m4       1/1     Running   0          25h   10.244.1.36      k8s-node01   <none>           <none>
nginx-ingress-controller-84d5b54fdf-n4wgs   1/1     Running   0          25h   192.168.101.28   k8s-node02   <none>           <none>
[root@k8s-master ingress]# 

三、書寫並執行 Service 服務

[root@k8s-master ingress]# vi service-nodeport.yml
apiVersion: v1
kind: Service
metadata:
  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx
spec:
  type: NodePort
  ports:
    - name: http
      port: 80
      targetPort: 80
      protocol: TCP
      nodePort: 32080  #http
    - name: https
      port: 443
      targetPort: 443
      protocol: TCP
      nodePort: 32443  #https
  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx

步驟如下

[root@k8s-master ingress]# vi service-nodeport.yml
[root@k8s-master ingress]# kubectl apply -f service-nodeport.yml 
service/ingress-nginx created
[root@k8s-master ingress]# kubectl get svc -n ingress-nginx
NAME                   TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                      AGE
default-http-backend   ClusterIP   10.107.251.54   <none>        80/TCP                       25h
ingress-nginx          NodePort    10.110.30.195   <none>        80:32080/TCP,443:32443/TCP   16s
[root@k8s-master ingress]#
