Environment details (AWS, VirtualBox, physical, etc.):

  • VirtualBox host (Ubuntu Vivid from cloud-images.ubuntu.com) running lxd
  • the lxc guest is running Ubuntu Trusty

How reproducible:

Steps to Reproduce:

  1. Boot ubuntu vivid vm in VirtualBox

  2. Install Docker on host (to make sure kernel has everything)

    1. wget -qO- https://get.docker.com/ | sh

  3. Install Lxd Container

    1. sudo apt-get install -y lxd
    2. sudo service lxd start
    3. sudo lxd-images import lxc ubuntu trusty amd64 --alias trusty
    4. sudo lxc launch trusty test
    5. sudo lxc exec test -- /bin/bash

  4. Install Docker on lxc guest

    1. apt-get install wget
    2. wget -qO- https://get.docker.com/ | sh

  5. Try to start Docker

    1. service docker start (fails)
    2. docker -d --exec-driver=lxc (fails)
    3. docker -d (fails)

    docker -d --exec-driver=lxc INFO[0000] +job serveapi(unix:///var/run/docker.sock)
    INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) FATA[0000] Shutting down daemon due to errors: error intializing graphdriver: permission denied

Actual Results:

Expected Results:

docker -d --exec-driver=lxc
...
INFO[0000] Daemon has completed initialization

Additional info:

docker -d --exec-driver=lxc
INFO[0000] +job serveapi(unix:///var/run/docker.sock)   
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) 
FATA[0000] Shutting down daemon due to errors: error intializing graphdriver: permission denied

When trying to run Docker in an ubuntu trusty lxc container created with lxd (cli, not openstack) on an ubuntu vivid host (created with vagrant from a cloud-images.ubuntu.com image) I get the following error:

# docker -d --exec-driver=lxc
INFO[0000] +job serveapi(unix:///var/run/docker.sock)   
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) 
FATA[0000] Shutting down daemon due to errors: error intializing graphdriver: permission denied

Following is a more complete log of what I tried:
