Answer 1

What if you do something like this, any request at / will get moved to ui service
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: poc-ingress
spec:
rules:
- host: poc.xxx.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: ui-service
port:
number: 443
- path: /backend
pathType: Prefix
backend:
service:
name: backend-service
port:
number: 443
However still if you are looking for a redirect solution you can follow below option
Add this annotation in ingress :
nginx.ingress.kubernetes.io/server-snippet: |
location ~ / {
rewrite / https://test.example.com/ui permanent;
}
if request comes at / it will get redirected to another domain or ui path as you wish.
You can also create the two ingress looks like this, first one check backend and / while another one handles ui :
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: poc-ingress
annotation:
nginx.ingress.kubernetes.io/server-snippet: |
location ~ / {
rewrite / https://test.example.com/ui permanent;
}
spec:
rules:
- host: poc.xxx.com
http:
paths:
- path: /backend
pathType: Prefix
backend:
service:
name: backend-service
port:
number: 443

apiVersion: networking.k8s.io/v1

metadata:
name: ui-ingress
spec:
rules:
- host: poc.xxx.com
http:
paths:
- path: /ui
pathType: Prefix

service:
name: ui-service
port:

Do not forget to use the ingress class annotation in ingress.
