Learning OpenStack Networking - Third Edition

By: James Denton

Overview of this book

OpenStack Networking is a pluggable, scalable, and API-driven system to manage physical and virtual networking resources in an OpenStack-based cloud. Like other core OpenStack components, OpenStack Networking can be used by administrators and users to increase the value and maximize the use of existing datacenter resources. This third edition of Learning OpenStack Networking walks you through the installation of OpenStack and provides you with a foundation that can be used to build a scalable and production-ready OpenStack cloud. In the initial chapters, you will review the physical network requirements and architectures necessary for an OpenStack environment that provide core cloud functionality. Then, you’ll move through the installation of the new release of OpenStack using packages from the Ubuntu repository. An overview of Neutron networking foundational concepts, including networks, subnets, and ports will segue into advanced topics such as security groups, distributed virtual routers, virtual load balancers, and VLAN tagging within instances. By the end of this book, you will have built a network infrastructure for your cloud using OpenStack Neutron.

Applying RBAC policies to projects

Before an RBAC policy can be created, you need to have a network or QoS policy that you wish to share among a subset of projects. In the following sections, we will create projects, roles, users, and networks, and I will demonstrate how an access control policy limits the visibility and use of shared resources between the projects versus the default behavior of the shared attribute.

Creating projects and users

Using the openstack client, let's create three projects named ProjectA, ProjectB, and ProjectC, as shown here:

Using the openstack client, create a role named rbacdemo. Then, create a user in each project and apply the rbacdemo role to each user:
