[lxc-users] iptabes kernel modules not loading in containers

[John Baker]

Hi,

I'm using lxc in 12.04.4 LTS and seem to have a chronic issue with the
iptables modfule not loading inside a container. I have found that it does
sometimes work and my coworker never seems to have problems with it in the
servers he runs. But it happens all the time on mine and I can't see
anything at all that we do differently. Sometimes it will start running
inside a container and then mysteriously have stopped next time I check in.
I can't find any error messages pertaining to it besides the one I get when
I try to load rules or view the set loaded.

The only fix I have been able to come up with is to manually
copy /lib/modules/<kernel ver.>-generic/modules.dep and net directory from
the host into the container. Then it seems willing to load iptables modules
consistently but always breaks when the kernel is updated on the host and
has to be redone.

Any ideas on what I might be missing? Is there a cgroup I should include
for sharing iptables modules?
