I don't speak about services in general. I speak about pods.

Imagine, you have "pod1" in your current context, and "pod2" in another
namespace, call it "another-namespace".

"kubectl get pods" shows you "pod1". "kubectl get pods --namespace
another-namespace" shows you "pod2".

"kubectl exec pod1 -it -- /bin/sh" access pod1 in your current
context. This is what we use when we access via remote file name syntax
"/kubernetes:pod1:".

pod2 is not accessible in your current context. But you could apply
"kubectl exec pod2 -it --namespace another-namespace -- /bin/sh". This
is what I mean with remote-file name syntax "/kubernetes:pod1.another-namespace:".

Is this possible?
