I have configured nginx-ingress-controller in kubernetes and I am trying to achieve method based routing from kubernetes.
This is my ingress.yaml file below:
kind: Ingress
metadata:
name: cafe-ingress-with-annotations
annotations:
kubernetes.io/ingress.class: "nginx"
#nginx.ingress.kubernetes.io/use-regex: "true"
#nginx.ingress.kubernetes.io/app-root: /
#nginx.ingress.kubernetes.io/ssl-redirect: "true"
nginx.ingress.kubernetes.io/configuration-snippet: |
location /tea {
limit_except GET {
deny all;
}
}
spec:
rules:
- host: cafe.example.com
http:
paths:
- path: /tea
backend:
serviceName: tea-svc
servicePort: 80
- path: /coffee
backend:
serviceName: coffee-svc
servicePort: 80according to the annotation defined it is supposed to block all other methods like POST/DELETE...etc except GET method. But it is not denying any of the methods. Please help me how can I achieve method based routing using limit_except in nginx. Thanks in advance.
As you can read in here, the configuration-snippet annotation is used for adding an additional configuration to the NGINX location.
If you want to add custom locations in the server block, you need to use server-snippet annotation. As you can read here:
Using the annotation
nginx.ingress.kubernetes.io/server-snippetit is possible to add custom configuration in the server configuration block.
The following Ingress manifest should work:
kind: Ingress
metadata:
name: cafe-ingress-with-annotations
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/server-snippet: |
location /tea {
limit_except GET {
deny all;
}
}
spec:
rules:
- host: cafe.example.com
http:
paths:
- path: /tea
backend:
serviceName: tea-svc
servicePort: 80
- path: /coffee
backend:
serviceName: coffee-svc
servicePort: 80
