I'm using nginx.ingress.kubernetes.io/permanent-redirect: https://www.google.com but want to pass down parameters after / in the redirect. But can't get it to work with pure ingress-nginx, would be sweet if you could set /$1 or something similar. Is this possible with a mix of other annotations or tricks?
For example https://www.example.com/hello
Should redirect to https://www.google.com/hello
It is possible to do this kind of redirection with following ingress.kubernetes.io/configuration-snippet configuration:
My ingress.yaml:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress-redirect
annotations:
nginx.ingress.kubernetes.io/server-snippet: |
return 301 http://www.google.com$request_uri;
spec:
rules:
- host: www.example.com
http:
paths:
- path: /
backend:
serviceName: servicename
servicePort: 80Apply ingress configuration:
$ kubectl apply -f ingress.yaml
ingress.extensions/ingress-redirect createdVerify ingress configuration and check its address.
$ kubectl describe ingress
Name: ingress-redirect
Namespace: default
Address: 10.156.0.33
Default backend: default-http-backend:80 (<none>)

And Finally test the if redirection works:
$ curl -v http://10.156.0.33/test/with?some=query -H "Host: www.example.com"
