I have a deployment configured with five replicas:

kubectl get pods

NAME                   READY     STATUS    RESTARTS   AGE
test-581957695-cbjtm   1/1       Running   3          1d
test-581957695-dnv8s   1/1       Running   1          1d
test-581957695-fv467   1/1       Running   1          1d
test-581957695-m74lc   1/1       Running   0          1d
test-581957695-s6cx0   1/1       Running   1          1d

kubectl describe services hellokube-service

...
Endpoints:      172.30.242.200:8080,172.30.242.201:8080,172.30.242.202:8080 + 2 more...
...

I need when a new replica is started that an external service contact with that replica to make some configuration on it.

Is it possible to connect directly with a specific replica using TCP/IP?

Thank you.
