我创建了一个 yaml 档案，它唯一的作业是： It should immediately redirect to google.com

但它只是不起作用......

我localhost还回来了404-nginx

我在 docker-desktop 上，我的 clusterversion 是 v1.21.5

这是我的redirect.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-google
  annotations:
    nginx.ingress.kubernetes.io/permanent-redirect: https://www.google.com
spec:
  rules:
  - http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: doesntmatter
            port:
              number: 80

这是我的 kubectl get ingress

NAME          CLASS    HOSTS                          ADDRESS     PORTS   AGE
cheddar       nginx    cheddar.127.0.0.1.nip.io       localhost   80      31m
my-google     <none>   *                                          80      26m
stilton       nginx    stilton.127.0.0.1.nip.io       localhost   80      31m
wensleydale   nginx    wensleydale.127.0.0.1.nip.io   localhost   80      31m

注意：其他入口服务例如cheddar.127.0.0.1.nip.io作业正常......

我猜你忘记了入口类名称。

spec:
  ingressClassName: nginx
  ...

除此之外，您还可以创建外部服务。

apiVersion: v1
kind: Service
metadata:
  name: google
spec:
  type: ExternalName
  externalName: www.google.com
  ports:
    - name: https
      port: 443
      protocol: TCP
      targetPort: 443

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: google
  labels:
    name: google
  annotations:
    nginx.ingress.kubernetes.io/backend-protocol: HTTPS
    nginx.ingress.kubernetes.io/upstream-vhost: www.google.com
spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: google
            port:
              name: https

请注意，来自入口控制器的证书不是谷歌的证书。因此，可能存在一些问题。一种可能有助于解决此类问题的设定是nginx.ingress.kubernetes.io/upstream-vhost如上所示的注释。
