How to know a Pod's own IP address from inside a container in the Pod?

Question

Kubernetes assigns an IP address for each container, but how can I acquire the IP address from a container in the Pod? I couldn\'t find the way from documentations.

Answer 1

Even simpler to remember than the sed approach is to use awk.

Here is an example, which you can run on your local machine:

kubectl describe pod `` | grep IP | awk '{print $2}'

The IP itself is on column 2 of the output, hence $2 .
