Kubernetes routing to specific pod in function of a param in url - kubernetes

Question

The need I have just looks like this stuff :
apiVersion: apps/v1beta1
kind: StatefulSet
metadata:
name: http
spec:
serviceName: "nginx-set"
replicas: 2
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: gcr.io/google_containers/nginx-slim:0.8
ports:
- containerPort: 80
name: http
----
apiVersion: v1
kind: Service
metadata:
name: nginx-set
labels:
app: nginx
spec:
ports:
- port: 80
name: http
clusterIP: None
selector:
app: nginx
Here is the interesting part :
apiVersion: voyager.appscode.com/v1beta1
kind: Ingress
metadata:
name: test-ingress
namespace: default
spec:
rules:
- host: appscode.example.com
http:
paths:
- path: '/testPath'
backend:
hostNames:
- web-0
serviceName: nginx-set #! There is no extra service. This
servicePort: '80' # is the Statefulset's Headless Service
I'm able to target a specific pod because of setting the hostName in function of the url.
Now I'd like to know if it's possible in kubernetes to create a rule like that
apiVersion: voyager.appscode.com/v1beta1
kind: Ingress
metadata:
name: test-ingress
namespace: default
spec:
rules:
- host: appscode.example.com
http:
paths:
- path: '/connect/(\d+)'
backend:
hostNames:
- web-(result of regex match with \d+)
serviceName: nginx-set #! There is no extra service. This
servicePort: '80' # is the Statefulset's Headless Service
or if I have to wrote a rule for each pod ?

Sorry that isn't possible, the best solution is to create multiple paths, each one referencing one pod:
apiVersion: voyager.appscode.com/v1beta1
kind: Ingress
metadata:
name: test-ingress
namespace: default
spec:
rules:
- host: appscode.example.com
http:
paths:
- path: '/connect/0'
backend:
hostNames:
- web-0
serviceName: nginx-set
servicePort: '80'
- path: '/connect/1'
backend:
hostNames:
- web-1
serviceName: nginx-set
servicePort: '80'
