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.

Deleting a Heat stack


To delete a running Heat stack we will make a simple call as shown in this recipe.

Getting ready

Ensure that you are logged on to a correctly configured OpenStack client and can access the OpenStack environment. Refer to Chapter 2, The OpenStack Client for details of setting up your environment to use OpenStack.

How to do it...

In this section, we'll show how to delete a stack.

  1. To delete a running stack named myStack, issue the following command:

    openstack stack delete myStack
    
  2. You will be prompted to confirm this deletion, as shown here. Type y to continue destroying the stack:

  3. You can check on the status of the deletion by listing the created stacks:

    openstack stack list
    

    This will bring back an empty list if there is no stack to show or the following during deletion:

How it works...

In very much the same way that we can launch a stack easily, deleting one is achieved by simply specifying which stack we want to destroy and using the stack delete command.

If you prefer to destroy...
