Hello,
I have a debian “Jessie” on my beaglebone black. I have installed docker and the version is “1.6.2”.
For the internet connection on my beaglebone black, i have shared the internet connection of my laptop with my board through USB.
Before i start a docker:
"
root@beaglebone:/home# ifconfig
docker0 Link encap:Ethernet HWaddr 72:91:a5:2c:9b:51

Once i start a docker, and ping 8.8.8.8 i will get the following,
"
root@84f465d6ba6f:/# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

"
and now exit the docker and check ifconfig,
"
root@beaglebone:/home# ifconfig

So there is an additional virtual ethernet and now even on the host, internet connection wont work.
"
root@beaglebone:/home# ping 8.8.8.8
