Flavors Extensions

This extension verifies that the given flavors exist in openstack.project configured in validator.yml.

Configuration

Create a flavors.yml which describes each flavor you want to check in OpenStack. You can describe a flavor using with the following key/value pairs:

key	value	mandatory
name	string	yes
vcpus	integer	yes
ram	integer [MiB]	yes
ephemeral	integer [GiB]	yes
metadata	key/value pairs	no

Each value is evaluated one to one against the flavor in OpenStack, except for ephemeral which is evaluated in one of the following ways:

• If the flavor only has Root Disk:

  Root Disk >= 3 [GiB] + ephemeral [GiB] + ram [GiB]

• If the flavor has Root Disk and Ephemeral Disk:

  Root Disk >= 3 and Ephemeral Disk >= ephemeral [GiB] + ram [GiB]

The OpenStack admin guide provides an overview of possible metadata.

Once all flavors are defined, configure the extension in the validator.yml:

extensions:
  paths: [./extensions/flavors]
  config:
    flavors:
     expected_flavors: </absolute/path/to/flavors.yml>

Examples

- name: m1.small
    vcpus: 1
    ram: 2048
    ephemeral: 0
- name: m1.medium
    vcpus: 2
    ram: 4096
    ephemeral: 0
    metadata:
      hw_rng:allowed: 'True'
