In Neutron, it is easy to create many private networks that allow communication between your instances. To allow access from your client to these, though, we must create a router on the provider network (an external network) that is routed into our OpenStack environment. This provider network allows us to allocate floating addresses to our instances.
Ensure that you have a suitable client available for using Neutron. If you are using the accompanying Vagrant environment, you can use the controller node. This has the python-neutronclient package installed that provides the neutron command-line client.
If you created this node with Vagrant, you can execute the following command:
vagrant ssh controller
Ensure you have the following credentials set (adjust the path to your certificates and key file to match your environment if not using the Vagrant environment):
export OS_TENANT_NAME=cookbook export OS_USERNAME=admin export OS_PASSWORD...
