How to rewrite a path to a backend service dropping the prefix and passing the remaining path?
Hello,
I am not sure whether my posting is appropriate in this area, so please delete it if there is a violation of posting rules...
This must be a common task, but I cannot figure out how to do the following fanout rewrite in our nginx ingress:
http://abcccc.com/httpbin/anything -> /anything (the httpbin backend service)
When I create the following ingress with a path of '/' and send the query, I receive a proper response.
curl -I -k http://abczzz.com/anything
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: mikie-ingress
namespace: mikie
spec:
ingressClassName: nginx
rules:
- host: abczzz.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: httpbin-service
port:
number: 8999
What I really need is to be able to redirect to different services off of this single host, so I changed the ingress to the following, but the query always fails with a 404. Basically, I want the /httpbin to disappear and pass the path onto the backend service, httpbin.
curl -I -k http://abczzz.com/httpbin/anything
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: mikie-ingress
namespace: mikie
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
ingressClassName: nginx
rules:
- host: abczzz.com
http:
paths:
- path: /httpbin(/|$)(.*)
pathType: Prefix
backend:
service:
name: httpbin-service
port:
number: 8999
Thank you for your time and interest,
Mike
