[CloudNative：KuberNetes&運維.V75]                                                                      [Applications.KuberNetes] [|DevOps|k8s|k8s運維|**3節點.V1**|IngressNginx自定義錯誤頁面|]

---

---

一、IngressNginx自定義錯誤頁面

### --- error_page配置：IngressNginx自定義錯誤頁面

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/server-snippet: error_page 404 https://www.baidu.com;
  name: ingress-test
  namespace: ratel-test1
spec:
  rules:
  - host: rewrite.test.com
    http:
      paths:
      - backend:
          serviceName: ingress-test
          servicePort: 80
        path: /something(/|$)(.*)
        pathType: ImplementationSpecific
 

二、通過瀏覽器訪問http://rewrite.test.com/會自動跳轉到百度 三、訪問something是有的 四、custom-http-errors ：全域性配置

### --- 修改configmap進行全域性配置

apiVersion: v1
data:
  custom-http-errors: 404,403
kind: ConfigMap
metadata:
  annotations:
    meta.helm.sh/release-name: ingress-nginx
    meta.helm.sh/release-namespace: ingress-nginx
    ratel.io/configMapLastVersion: "3"
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/version: 0.40.2
    helm.sh/chart: ingress-nginx-3.6.0
  name: ingress-nginx-controller
  namespace: ingress-nginx
 

### --- 修改controller檔案，把default-backend修改自己配置的引數

[root@k8s-master01 ~]# kubectl edit ds -n ingress-nginx
      containers:
      - args:
        - /nginx-ingress-controller
        - --default-backend-service=ratel-test1/ingress-test

### --- 重啟容器

[root@k8s-master01 ~]# kubectl delete po -n ingress-nginx --all
pod "ingress-nginx-controller-89z64" deleted
pod "ingress-nginx-controller-rjfpw" deleted
pod "ingress-nginx-controller-rlcwb" deleted 
 

五、訪問測試：http://krm.test.com/404：重定向到V1上面了；跳轉到後端service上面
