Zun DevStack installation

We will now look at how to install a development setup of Zun using DevStack:

Create a root directory for DevStack if needed:

$ sudo mkdir -p /opt/stack$ sudo chown $USER /opt/stack

To clone DevStack repository, do the following:

$ git clone https://git.openstack.org/openstack-dev/devstack 
/opt/stack/devstack

Now, create a minimal local.conf for running the DevStack setup. We will enable the following plugins to create a Zun setup:

• devstack-plugin-container: This plugin installs Docker
• kuryr-libnetwork: This is the Docker libnetwork driver that uses Neutron to provide networking services
