how to configure ingress

Answer 1

If you are using the Nginx ingress you can do routing using
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
name: rewrite
namespace: default
spec:
rules:
- host: rewrite.bar.com
http:
paths:
- backend:
serviceName: service-1
servicePort: 80
path: /service-1(/|$)(.*)
- backend:
serviceName: service-2
servicePort: 80
path: /service-2(/|$)(.*)
For example, the ingress definition above will result in the following rewrites:
rewrite.bar.com/service1 rewrites to rewrite.bar.com/
rewrite.bar.com/service1/ rewrites to rewrite.bar.com/
rewrite.bar.com/service1/new rewrites to rewrite.bar.com/new
Refer : https://kubernetes.github.io/ingress-nginx/examples/rewrite/
Extra
If you don't want to remove service name or rewrite simple use this config
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
kubernetes.io/ingress.class: haproxy
name: simple
namespace: default
spec:
rules:
- host: simple.bar.com
http:
paths:
- backend:
serviceName: service-1
servicePort: 80
path: /service-1
- backend:
serviceName: service-2
servicePort: 80
path: /service-2

Thats how you should do it (nginx ingress):
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: my-ingress
namespace: my-ingress-namespace
spec:
rules:
- host: exturi
http:
paths:
- backend:
service:
name: service1
port:
number: 80
path: /service1/(.*)
pathType: ImplementationSpecific
- backend:
service:
name: service2
port:
number: 80
path: /service2/(.*)
pathType: ImplementationSpecific
status:
loadBalancer:
ingress:
- ip: {}
