Need to set the ip and/or any metadata of the deployment to be available as env vars to each pod under the same deployment...
ex: having a 3 replica deploment. need to set env var for other IP address for each of the two other pods. need to set the host name for each other two pods. as of having
HOSTNAME=deplymentNAME-d74cf6f77-q57jx
deplymentNAME_PORT=tcp://10.152.183.27:13000
need to add:
HOSTNAME2=deplymentNAME-d74cf6f77-y67kl
HOSTNAME3=deplymentNAME-d74cf6f77-i90ro
deplymentNAME_PORT2=tcp://10.152.183.45:13000
deplymentNAME_PORT3=tcp://10.152.16.28:13000
those should be available on the three pods relatively. as of now each pod have only its own data, we need to spread others data to the other replicas in the same deployment.

Well, I figured out that my application is a stateful and not stateless application, that requires fixed/stable hostname/storage etc...
I have decided to use the statefulset controller
