Connect to a service in another pod in same namespace without using namespace in URL

Question

How to access a service from another pod in same namespace without using namespace name in URL?

Can't use this as it is using namespace name in url. <service-name>.<namespace>.svc.cluster.local

Reason: namespace names are dynamic in my setup and not in my control.

Answer 1

You can just directly use the other Service name as a host name if you know it's in the same namespace as your Pod.

http://<service-name>/path

DNS for Services and Pods documents that both svc.cluster.local and <namespace>.svc.cluster.local are added to the default DNS search path (in the container's /etc/resolv.conf file), which makes this work.
