<p class="MsoNormal">Kernel modules aren't loaded per-container but globally for the whole host.<br>
<br>
It's not recommended (and usually blocked by either dropping the<br>
capability or by having apparmor prevent it) to load modules from within<br>
a container. Instead you should make sure all your kernel modules are<br>
loaded from the host before you start your containers.<br>
<br>
I suspect the difference between your server and your colleague's is<br>
that he has some init scripts or something else calling iptables before<br>
he starts his containers which will load any modules required by his<br>
container.<br>
