Is there any possibility to create a service which is able to route traffic to selected pod(not pod group).
Example: myservice.whatever:1000/podNameAppName to route to custom pod ?
As mentioned by Alassane Ndiaye for internal routing. In addition if this question is related to the external requests you should create more advanced application design.
Please take a look for ADC concept like NGINX ADC, ISTIO Design Pattern and ADC overview.
Basically this task should be implemented at higher level using all benefits from L7 loadbalncing support.
Please take a look also for K8s concepts
Hope this help.
