I have two service serviceOld serviceNew
I want to achieve the following effect
http://host/any => http://serviceOld/any
http://host/any/aaa => http://serviceOld/any/aaa
http://host/feature => http://serviceNew/feature
http://host/feature/bbb => http://serviceNew/feature/bbb
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/canary: "true"
nginx.ingress.kubernetes.io/canary-by-header: new
nginx.ingress.kubernetes.io/rewrite-target: /
name: v2
namespace: api
spec:
rules:
- host: xxx.com
http:
paths:
- path: /
backend:
serviceName: serviceOld
servicePort: 80
- path: /feature/*
backend:
serviceName: serviceNew
servicePort: 8080
I tried multiple methods and failed to achieve the goal. Can anyone help me?
All you need about rewrite annotation and path can be found in Ingress Rewrite Docs.
As per example on the site:
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
name: rewrite
namespace: default
spec:
rules:
- host: rewrite.bar.com
http:
paths:
- backend:
serviceName: http-svc
servicePort: 80
path: /something(/|$)(.*)
It will redirect:
rewrite.bar.com/something rewrites to rewrite.bar.com/
rewrite.bar.com/something/ rewrites to rewrite.bar.com/
rewrite.bar.com/something/new rewrites to rewrite.bar.com/new
In your case it should looks like:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /$2
name: v2
namespace: api
spec:
rules:
- host: xxx.com
http:
paths:
- path: /any(/|$)(.*)
backend:
serviceName: serviceOld
servicePort: 80
- path: /feature(/|$)(.*)
backend:
serviceName: serviceNew
servicePort: 8080
I found that my version is relatively old. Under the old version, if the ports are different, it will not work properly. Change to the same port or upgrade the ingress version
