This commit extends the existing Docker driver to leverage Nova to provision sandbox. In other words, there are two drivers: 1. docker.driver.DockerDriver (default) 2. docker.driver.NovaDockerDriver Users can choose which driver they want to use. The major difference is the second driver integrate with Neutron, Neutron is used to provide networking for container. The files under nova/* were copied from nova-docker with minor modification (mainly for fixing bugs and removing unused codes). In particular, nova/virt/docker/driver.py contains a DockerDriver for Nova. It implements the Nova virt driver interface using docker. This custom virt driver is used to create/delete/manage sandbox containers. At this commit, we hardcoded the flavor to m1.small and nics to 'auto' when creating sandbox instances. We might make them as parameters and specified by end-users. The flavor will decide the resource constraints of the container and nics will decide how the networking of the container being configured. The docker image kubernetes/pause is chosen to be the image of the sandbox container, since its size is small and statisfies what we want (an empty container that keeps running). When creating the sandbox, we haven't specify the security group yet so the default security group is used. Users need to open ports in that security groups to access container from outside. Later, we could create a custom security group for each container, and automatically open ports that are exposed by the container.

DevStack Integration
This directory contains the files necessary to integrate zun with devstack.
Refer the quickstart guide at https://github.com/openstack/zun/blob/master/doc/source/dev/quickstart.rst for more information on using devstack and zun.
To install zun into devstack, add the following settings to enable the zun plugin:
cat > /opt/stack/devstack/local.conf << END
[[local|localrc]]
enable_plugin zun https://git.openstack.org/openstack/zun master
ENDThen run devstack normally:
cd /opt/stack/devstack
./stack.sh
