title: how to change MTU inside docker container on ubuntu 14.4
body: <p>I want to change <em>MTU(Maximum Transmission Unit)</em> inside <code>docker</code> which is running on ubuntu 14.04. Also docker container running with ubuntu 14.04. </p>
  
  <p>The problem is that its <code>docker0</code> 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.</p>
  
  <p>I had also tried with creating bridge connection with new interface but while I up that interface its down my whole network and doesn't work anymore.</p>
  
  <p>Help will be highly appreciated</p>
