详细说明： Chapter 1, Introduction to OpenStack, provides the high-level overview of OpenStack and the projects that make up this cloud platform. This introduction will set the level for the reader on the OpenStack components, concepts, and verbiage. Chapter 2, Introductio n to Ansible, gives the detailed review of Ansible 2.0, its features, and the best practices to set a solid starting foundation. Also, it will review why leveraging Ansible to automate OpenStack tasks is the easiest option. Chapter 3, Creating Multiple Users/Tenants, guides the reader through the process of creating users and tenants within OpenStack manually and the creation considerations in order to automate such a process using Ansible. Chapter 4, Customizing Your Clouds Quotas, makes you understand what quotas are and how they are used to restrict your cloud resources. It shows the reader how to create quotas manually in OpenStack. After this, it explains how to automate this process with Ansible in order to handle the task for multiple tenants at one time. Chapter 5, Snapshot Your Cloud, teaches how to create snapshots of your cloud instances manually within OpenStack and how to automate this process using Ansible. It explores the power of being able to snapshot all instances within a tenant in one shot. Chapter 6, Migrating Instances, introduces the concept of migrating select instances across compute nodes in the traditional OpenStack method. Then, it demonstrates the required steps to automate this task while grouping instances together and shows the additional options Ansible can offer in handling a task of this matter. Chapter 7, Managing Containers on Your Cloud, takes the reader through a few strategies on how you can automate building and deploying containers running on your OpenStack cloud. There are a few approaches now available, but the key is automating the process so that it is a reuseable function. For each approach, the chapter shows the building blocks of how to accomplish this successfully with OpenStack. Chapter 8, Setting up Active-Active Regions, gives the detailed review of a few use cases of setting up an Active-Active OpenStack cloud regions. With that knowledge, you will then physically learn how to automate this to deploy onto your clouds. Chapter 9, Inventory Your Cloud, explores how the reader can dynamically inventory all the OpenStack cloud user resources with one Ansible playbook. It walks them through the necessary metrics to gather and how that information can be stored for later reference. This is a very powerful tool to have as a cloud administrator/operator. Chapter 10, Health Check Your Cloud with Nagios, demonstrates some useful tips and tricks on how to check the health of your cloud manually and leverage Ansible to set up Nagios and the necessary checks to monitor your cloud. Nagios is one of the leading open source monitoring platforms out there and compliments OpenStack and Ansible very well. ...展开收缩
