How can i change MY_POD_IP via external pod service_name

[sonerkoylu]

Hi.
I used before opentelemetry on docker. It was so easy. But now, i am trying to run my containers on k8s a lot of bad experience with opentelemetry.

When i changed the MY_POD_IP via pod service_name the app could not connect.
