Public bug reported:
Steps to reproduce:
1. Take any fresh installation of Ubuntu 16.04. I used Vagrant to
reproduce this bug, but it also reproduces on my VM with Ubuntu 16.04 in
Azure.
2. Upgrade kernel to current latest release (linux-
image-4.4.0-36-generic).
# uname -r
4.4.0-36-generic
3. Install Docker 1.11.2 from Ubuntu repositories (also can be
reproduced with Docker 1.12.1 from official Docker repositories for
Debian/Ubuntu):
# apt install docker.io
4. Use overlayfs as storage driver in Docker. Edit /etc/default/docker
and add DOCKER_OPTS="--storage-driver=overlay":
# echo 'DOCKER_OPTS="--storage-driver=overlay"' >> /etc/default/docker
# systemctl restart docker
# docker info
