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.

Common OpenStack server (instances) tasks


This section outlines a number of common commands that can be run when operating with instances (for example, virtual machines). For more detailed information and explanation of each task, refer to Chapter 5, Nova – OpenStack Compute.

Getting ready

Ensure that you have the OpenStack clients installed as described in the first recipes of this chapter.

How to do it…

Carry out the following to launch and manipulate running instances:

Launching an instance

To launch in an instance from the command line, you need the following information:

  • An image

  • A network

  • A flavor

  • An optional security group (default is used otherwise)

  • An optional key (if you intend to access the instance)

Carry out the following steps to launch an instance from the command line:

  1. First, list the images available:

    openstack image list
    
  2. Now we list the networks available (it will be the UUID of the Network we will use):

    openstack network list
    
  3. We need a flavor, if you need reminding of them, list them...
