This is a Python wrapper for the setns() system call.

Examples

Show interface configuration inside a named network namespace:

import netns
import subprocess

with netns.NetNS(nsname='myns'):
    subprocess.call(['ip', 'a'])

Inspect the interface configuration inside a docker container (assuming that you have retrieved the container pid via docker inspect output or by using the Docker API):

with netns.NetNS(nspid=29435):
    subprocess.call(['ip', 'a'])

Create a socket inside a network namespace:

sock = netns.socket(netns.get_ns_path(nsname='myns'))
