Deleting a host aggregate

When a host aggregate no longer applies in a given environment, it can be deleted. A host aggregate must have all hosts removed before it can be removed.

Getting ready

To delete a host aggregate, you will need the following information:

• The openstack command-line client

• The openrc file containing appropriate credentials

• The name or ID of the aggregate

For the following example, we will delete the cookbook-threadripper-hosts aggregate.

How to do it…

The following commands are used to delete a host aggregate:

1. First, list the existing aggregates:

   openstack aggregate list
   

   This will bring back the following output:

   

2. Confirm that the aggregate has no hosts (Refer to the Removing a compute host from a host aggregate recipe if necessary):

   openstack aggregate show cookbook-threadripper-hosts
   

   This will bring back the following output:

   

3. Now we can delete the aggregate with the following command:

   openstack aggregate delete cookbook-threadripper-hosts
   

   Note

   This command produces no output...
