ethtool plugin inside container does not work.

[ampatel1]

Hi ethtool plugin developer community,

I have SUT with Intel Broadwell CPU with CentOS 7 as base OS. I am also running CentOS:7 container form docker hub with docker run -it command.

on base OS ethtool plugin work just fine. however inside CentOS 7 container ethtool plugin does not work.

I have invoked container in privileged mode and I am also using "--net=host" option to make network ports and settings visible from base OS to inside container. I have installed "ethtool" package inside centOS 7 container.

still problem persist; inside container ethtool plugin does not work.

I can be reached over ankit.m.patel@intel.com for more details

thanks Ankit

@ankitpatelintel so looks like --net=host and mounting docker/ns seems to provide sufficient info (see https://github.com/docker/docker/issues/14666):

$ docker run --net=host -v /var/run/docker/netns:/var/run/netns intelsdi/snap:xenial

omitting installation of ethtool package:

$ docker exec -it 3d1 /bin/bash

loading the plugin seems to get the correct metrics:
