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.

Deleting networks


Deleting a network in OpenStack is as easy as invoking the openstack network delete command. Neutron will delete any automatically-created ports associated with the network, like the ones created by/for the DHCP or router namespaces, and will return any automatically-assigned segmentation IDs to the respective pool for allocation to another network.

Getting ready

When deleting a network in OpenStack, ensure that all associated user-created ports have been deleted. This may require deleting instances, detaching and deleting ports from instances, or detaching and deleting ports from routers. When deleting a network, the following information will be necessary:

  • Network name or ID

How to do it…

With the OpenStack client installed on our system, we are able now to delete a network with the following command:

openstack network delete COOKBOOK_TENANT_NETWORK_3

No output is returned.

How it works...

When invoked, the openstack network delete command will instruct Neutron to delete the...
