os_flavor_facts - Retrieve facts about one or more flavors

New in version 2.1.

Synopsis

Retrieve facts about available OpenStack instance flavors. By default, facts about ALL flavors are retrieved. Filters can be applied to get facts for only matching flavors. For example, you can filter on the amount of RAM available to the flavor, or the number of virtual CPUs available to the flavor, or both. When specifying multiple filters, ALL filters must match on a flavor before that flavor is returned as a fact.

Requirements (on host that executes module)

  • python >= 2.6
  • python >= 2.7
  • shade

Options

parameter required default choices comments
api_timeout
 no None
How long should the socket layer wait before timing out for API calls. If this is omitted, nothing will be passed to the requests library.
auth
 no
Dictionary containing auth information as needed by the cloud's auth plugin strategy. For the default password plugin, this would contain auth_url, username, password, project_name and any information about domains if the cloud supports them. For other plugins, this param will need to contain whatever parameters that auth plugin requires. This parameter is not needed if a named cloud is provided or OpenStack OS_* environment variables are present.
auth_type
 no password
Name of the auth plugin to use. If the cloud uses something other than password authentication, the name of the plugin should be indicated here and the contents of the auth parameter should be updated accordingly.
availability_zone
 no
Name of the availability zone.
cacert
 no None
A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
cert
 no None
A path to a client certificate to use as part of the SSL transaction.
cloud
 no
Named cloud to operate against. Provides default values for auth and auth_type. This parameter is not needed if auth is provided or if OpenStack OS_* environment variables are present.
endpoint_type
 no public
  • public
  • internal
  • admin
Endpoint URL type to fetch from the service catalog.
key
 no None
A path to a client key to use as part of the SSL transaction.
limit
 no None
Limits the number of flavors returned. All matching flavors are returned by default.
name
 no None
A flavor name. Cannot be used with ram or vcpus.
ram
 no
A string used for filtering flavors based on the amount of RAM (in MB) desired. This string accepts the following special values: 'MIN' (return flavors with the minimum amount of RAM), and 'MAX' (return flavors with the maximum amount of RAM).
A specific amount of RAM may also be specified. Any flavors with this exact amount of RAM will be returned.
A range of acceptable RAM may be given using a special syntax. Simply prefix the amount of RAM with one of these acceptable range values: '<', '>', '<=', '>='. These values represent less than, greater than, less than or equal to, and greater than or equal to, respectively.
region_name
 no
Name of the region.
timeout
 no 180
How long should ansible wait for the requested resource.
validate_certs
 no True
Whether or not SSL API requests should be verified.
aliases: verify
vcpus
 no
A string used for filtering flavors based on the number of virtual CPUs desired. Format is the same as the ram parameter.
wait
 no yes
  • yes
  • no
Should ansible wait until the requested resource is complete.

Examples

# Gather facts about all available flavors
- os_flavor_facts:
    cloud: mycloud

# Gather facts for the flavor named "xlarge-flavor"
- os_flavor_facts:
    cloud: mycloud
    name: "xlarge-flavor"

# Get all flavors that have exactly 512 MB of RAM.
- os_flavor_facts:
    cloud: mycloud
    ram: "512"

# Get all flavors that have 1024 MB or more of RAM.
- os_flavor_facts:
    cloud: mycloud
    ram: ">=1024"

# Get a single flavor that has the minimum amount of RAM. Using the 'limit'
# option will guarantee only a single flavor is returned.
- os_flavor_facts:
    cloud: mycloud
    ram: "MIN"
    limit: 1

# Get all flavors with 1024 MB of RAM or more, AND exactly 2 virtual CPUs.
- os_flavor_facts:
    cloud: mycloud
    ram: ">=1024"
    vcpus: "2"

Return Values

disk Size of local disk, in GB. success int 10
id Flavor ID. success string 515256b8-7027-4d73-aa54-4e30a4a4a339

Notes

Note

This module creates a new top-level openstack_flavors fact, which contains a list of unsorted flavors.

Note

The standard OpenStack environment variables, such as OS_USERNAME may be used instead of providing explicit values.

Note

Auth information is driven by os-client-config, which means that values can come from a yaml config file in /etc/ansible/openstack.yaml, /etc/openstack/clouds.yaml or ~/.config/openstack/clouds.yaml, then from standard environment variables, then finally by explicit parameters in plays. More information can be found at http://docs.openstack.org/developer/os-client-config
