how to change MTU inside docker container on ubuntu 14.4

I want to change MTU(Maximum Transmission Unit) inside docker which is running on ubuntu 14.04. Also docker container running with ubuntu 14.04.

The problem is that its docker0 interface on host os can change the MTU value from 1500 to 9000 but its doesn’t gives affects inside docker os. means inside docker it is running with a older value i.e 1500. And when I restart the docker services on host machine its all changes goes to default.

    See docs.docker.com/articles/networking/#docker0 extract “

    --mtu=BYTES — override the maximum packet length on docker0.
    

    On Ubuntu you would add these to the DOCKER_OPTS setting in /etc/default/docker on your Docker host and restarting the Docker service.”
