Often times, requirements change; there is a demand for more performance, or business needs change. Whatever be the reason, your existing flavors may not meet the needs of those consuming cloud resources. When a given flavor is no longer suitable, it will need to be deleted.
To change attributes of a flavor for Nova, you will need the following:
- The
openstackcommand-line client - The
openrcfile containing appropriate credentials - The name of the flavor to delete
The following commands are used to delete a flavor:
- First, list the flavors available:
openstack flavor listThis will bring back a list of flavors like the following:
- To delete the flavor, execute the following command:
openstack flavor delete openstack.cookbook - List the flavors again to view updated attributes:
