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.

Adding a compute host using OpenStack-Ansible


In order to run instances, OpenStack Compute needs to be aware of the physical resources on which to run the instances. As OpenStack has grown and matured over time, the process for adding a host has also grown with it. OpenStack-Ansible provides a very convenient and consistent method for adding new compute hosts which allows you to scale your environment as your needs grow. A compute host runs the nova-compute service and the hypervisor that spawns the appropriate instance type requested.

Getting ready

In order to add a compute host to an OpenStack cluster using openstack-ansible, you will need the following information:

  • The IP address of the host

  • SSH access to the host

  • The SSH key from your deployment host

  • Access to the deployment host

The values used in our example are as follows:

  • Compute host: 172.29.236.15

  • Deployment host: controller-01.cook.book

We assume that your environment was already installed using OpenStack-Ansible as described in Chapter...
