Flavors CLI reference

See https://docs.openstack.org/nova/2023.2/cli/index.html.

These commands allow you to create, list, show, delete, and manage properties and access for flavors. The <flavor_id_or_name> and <project_id> in the commands are placeholders that should be replaced with the actual IDs or names of the flavors and projects. Here is a list of some common commands for working with flavors.
