Method Based Routing in Nginx Ingress

[abhijitvikash]

Hi Nginx, I want to implement method based routing(GET PUT OPTIONS) in Nginx Ingress. But seems like this is not supported either using :
nginx.ingress.kubernetes.io/configuration-snippet
nginx.ingress.kubernetes.io/server-snippet:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: testing-ingress-01
annotations:
nginx.ingress.kubernetes.io/configuration-snippet: |
set $target_backend "httpd-service.default.svc.cluster.local";
if ($request_method = 'PUT') {
set $target_backend "httpd-service.default.svc.cluster.local"; # Change this to your PUT service if needed
}
if ($request_method = 'GET') {
set $target_backend "httpd-service.default.svc.cluster.local"; # Change this to your GET service if needed
}
proxy_pass http://$target_backend;
spec:
ingressClassName: nginx
rules:

• http:
  paths:
  • path: /
    pathType: ImplementationSpecific
    backend:
    service:
    name: httpd-service
    port:
    number: 80

Hi @abhijitvikash thanks for reporting!

Be sure to check out the docs and the Contributing Guidelines while you wait for a human to take a look at this 🙂

I've parsed the text of your issue and it looks like you might be mixing up the two Ingress Controllers, please take a look at this page to see the differences between nginxinc/kubernetes-ingress (this repo) and kubernetes/ingress-nginx.

Cheers!

Method based routing.
As in, a GET is sent to one service, a PUT to a different service, a POST to yet a different service, and so on.
Did I get that correct?

I am asking because the project offers Method filtering / blocking which might also meet the need.

@brianehlert I think @abhijitvikash is using community project looking at the annotations here.
@abhijitvikash can you please specify which project you're using along with version?

helm template my-nginx ingress-nginx/ingress-nginx --values values-ext.yaml --namespace ingress-nginx > nginx-ingress-external-manifest.yaml

@abhijitvikash Hello there.
That repo you listed is a different NGINX ingress controller project.
This repo is the official NGINX Ingress controller project maintained by NGINX.

You can see our documentation located here:

https://docs.nginx.com/nginx-ingress-controller/

If you are using the ingress resource, you can use snippets:

https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/advanced-configuration-with-snippets/

If you are using our CRD definitions, you can use snippets as well:

https://docs.nginx.com/nginx-ingress-controller/configuration/virtualserver-and-virtualserverroute-resources/#using-snippets

Let us know if that helps.
