I am trying to access a url example.com/service/test1 but it redircts me to example.com/login.

Below is my YAMl file:

apiVersion: extensions/v1beta1
kind: Ingress
  name: test-ing
  namespace: test
     nginx.ingress.kubernetes.io/ssl-redirect: "false"
     nginx-ingress.kubernetes.io/use-regex: true

  - host: example.com
      - backend:
          serviceName: svc-test
          servicePort: 8080
        path: /service/test
  - secretName: tls-secret

It just works

Your configuration is correct.

Provided YAML file generates nginx config like this:

server {
 listen       80;
 server_name  example.com;
 location ~* "^/service/test" {
   root    /var/www/example.com/htdocs;

Testing this config via this cool tester shows that location filter works:

  • http://example.com/service/test1 -> Location: ^/service/test
  • http://example.com/service/test -> Location: ^/service/test
  • http://example.com/login -> Errors: No locations matched

For more details, see this explanation of Ingress Path Matching and examples from NGINX Docs:

  • Examples show how to use advanced NGINX features in Ingress resources with annotations.
  • Examples of Custom Resources show how to use VirtualServer and VirtualServerResources for a few use cases.

Check your app

Check your app, maybe it forward non-authorized requests to /login url. You may use curl -v or wget, e.g:

curl -v -L http://example.com/service/test1 | egrep "^> (Host:|GET)"
wget  http://example.com/service/test1 2>&1 | grep Location

Howto debug nginx ingress

There is an Nginx debug mode for debugging nginx locations and redirects. To enable it, use --v=5 in kubectl edit deploy.

See: k8s debug logging:

Using the flag --v=XX it is possible to increase the level of logging. This is performed by editing the deployment.

$ kubectl get deploy -n <namespace-of-ingress-controller>
default-http-backend       1         1         1            1           35m
nginx-ingress-controller   1         1         1            1           35m

$ kubectl edit deploy -n <namespace-of-ingress-controller> nginx-ingress-controller
# Add --v=X to "- args", where X is an integer
  • --v=2 shows details using diff about the changes in the configuration in nginx
  • --v=3 shows details about the service, Ingress rule, endpoint changes and it dumps the nginx configuration in JSON format
  • --v=5 configures NGINX in debug mode
  • The /login page was coming from the container, it was not the nginx redirects. Thanks, debug mode helped in unfold the ingress Apr 4, 2020 at 5:08
  • Hi @pradeep-upadhyay. Glad that my answer helped you. Correct, nginx redirects work as I described. And redirects to /login was due to application. As I wrote: 'Your configuration is correct.'
