Overview of this book

This is the fourth edition of the industry-acclaimed OpenStack Cloud Computing Cookbook, created by four recognized OpenStack experts. It has now been updated to work with the latest OpenStack builds, using tools and processes based on their collective and vast OpenStack experience. OpenStack Open Source Cloud software is one of the most used cloud infrastructures to support a wide variety of use cases, from software development to big data analysis. It is developed by a thriving community of individual developers from around the globe and backed by most of the leading players in the cloud space today. We make it simple to implement, massively scalable, and able to store a large pool of data and networking resources. OpenStack has a strong ecosystem that helps you provision your cloud storage needs. Add OpenStack's enterprise features to reduce the cost of your business. This book will begin by showing you the steps to build up an OpenStack private cloud environment using Ansible. You'll then discover the uses of cloud services such as the identity service, image service, and compute service. You'll dive into Neutron, the OpenStack Networking service, and get your hands dirty with configuring networks, routers, load balancers, and more. You’ll then gather more expert knowledge on OpenStack cloud computing by managing your cloud's security and migration. After that, we delve into OpenStack Object storage and you’ll see how to manage servers and work with objects, cluster, and storage functionalities. Finally, you will learn about OpenStack dashboard, Ansible, Keystone, and other interesting topics.

Configuring groups in Keystone


If you wish to organize users by their roles, you can create a user group using Keystone groups. Groups are owned by a domain. In this example, we will create one group, reader_group, and set a cloud_admin role to it. We will also add two users to it, reader and reader1. We will also verify that the users belong to the group, as well as remove one of the users afterwards.

Getting ready

Ensure that you are logged on to a correctly configured OpenStack client and can access the OpenStack environment as a user with admin privileges.

Refer to Chapter 2, The OpenStack Client, for details of setting up your environment to use OpenStack command-line client.

How to do it…

In order to create groups and assign users to them, we will need to execute the following steps:

  1. Start by creating a group:

    openstack group create --domain bookstore
        --description "Bookstore reader group"
        reader_group
    
  2. List existing groups:

    openstack group list
    
  3. Add group to the role:

    openstack role...
