404 when trying to access ingress from postman

问题

I have an ingress controller with two services running behind it. I also have an SSL certificate installed with Lets Encrypt and cert-manager.

For some reason, whenever I make a request to my endpoints, it returns a 404 not found error. For example:

http://stefandeboer.com/api/neume-billing-service/Transaction

returns:

  1. <html>
  3. <head>
  4. 	<title>404 Not Found</title>
  5. </head>
  7. <body>
  8. 	<center>
  9. 		<h1>404 Not Found</h1>
  10. 	</center>
  11. 	<hr>
  12. 	<center>nginx</center>
  13. </body>
  15. </html>

This is the YAML for my ingress:

  1. apiVersion: networking.k8s.io/v1
  2. kind: Ingress
  3. metadata:
  4.   annotations:
  5.     cert-manager.io/cluster-issuer: letsencrypt
  6.     kubernetes.io/ingress.class: nginx
  7.     nginx.ingress.kubernetes.io/rewrite-target: /
  8.     nginx.ingress.kubernetes.io/use-regex: "true"
  9.   creationTimestamp: "2023-06-05T22:51:36Z"
  10.   generation: 3
  11.   name: neume-ingress
  12.   namespace: default
  13.   resourceVersion: "1888643"
  14.   uid: 9abf4d0f-3370-4856-b3e2-c555c7042739
  15. spec:
  16.   rules:
  17.   - host: stefandeboer.com
  18.   - http:
  19.       paths:
  20.       - backend:
  21.           service:
  22.             name: neume-user-service
  23.             port:
  24.               number: 80
  25.         path: /api/neume-user-service(/|$)(.*)
  26.         pathType: Prefix
  27.       - backend:
  28.           service:
  29.             name: neume-billing-service
  30.             port:
  31.               number: 80
  32.         path: /api/neume-billing-service(/|$)(.*)
  33.         pathType: Prefix
  34.   tls:
  35.   - hosts:
  36.     - stefandeboer.com
  37.     secretName: tls-secret
  38. status:
  39.   loadBalancer:
  40.     ingress:
  41.     - ip: 20.4.165.91

Both my pods are running in the same namespace:

  1. NAME                                                READY   STATUS    RESTARTS   AGE
  2. neume-billing-service-deployment-769ff6487b-sjk5d   1/1     Running   0          31m
  3. neume-user-service-deployment-5674b4b75d-8zhgp      1/1     Running   0          29m

What could I be doing wrong here?

It looks like you have a configuration issue with your ingress. The host declaration must be part of the same object as the HTTP declaration.

Instead of:

  1.   rules:
  2.   - host: stefandeboer.com
  3.   - http:

You need to do it like this:

  1.    rules:
  2.    - host: stefandeboer.com
  3.      http:

在对我的YAML文件进行一些调整后，它就像魔法一样运行了！我将http放在主机对象下，并确保在目标重写之后添加了$2。

  24.               number: 80

After making some tweaks to my YAML file it worked like a charm!
I put the http under the host object and made sure to add the $2 after the target-rewrite.
