title: How to change mtu size inside docker container?
body: <p>I would like to change the MTU size from specific container, not at docker host, but any command are working, I've tried:
  <strong>ifconfig eth0 mtu 1400</strong> and <strong>ip link set mtu 1400 dev eth0</strong>, but I've got "operation not permited", I'm already root user.</p>
