How to get the current namespace in a Pod?

Question

One way I could think of is to set an environment which value is the namespace of the Pod when defining the Pod.
Getting the namespace dynamically without requiring changes for Pod will be better because it lessens the burden of constructing a Pod.

So is there a way to get current namespace in a Pod?

Try the file:

/var/run/secrets/kubernetes.io/serviceaccount/namespace
