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

The container's IP address should be properly configured inside of its network namespace, so any of the standard linux tools can get it. For example, try ifconfig, ip addr show, hostname -I, etc. from an attached shell within one of your containers to test it out.
