openstack.cloud.compute_flavor_info module – Retrieve information about one or more flavors

Note

This module is part of the openstack.cloud collection (version 1.10.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install openstack.cloud. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: openstack.cloud.compute_flavor_info.

Synopsis

  • Retrieve information about available OpenStack instance flavors. By default, information about ALL flavors are retrieved. Filters can be applied to get information 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.

  • This module was called openstack.cloud.compute_flavor_facts before Ansible 2.9, returning ansible_facts. Note that the openstack.cloud.compute_flavor_info module no longer returns ansible_facts!

Requirements

The below requirements are needed on the host that executes this module.

  • openstacksdk

  • openstacksdk >= 0.36, < 0.99.0

  • python >= 3.6

Parameters

Parameter

Comments

api_timeout

integer

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

dictionary

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 (for example, user_domain_name or project_domain_name) 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

string

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

string

Ignored. Present for backwards compatibility

ca_cert

aliases: cacert

string

A path to a CA Cert bundle that can be used as part of verifying SSL API requests.

client_cert

aliases: cert

string

A path to a client certificate to use as part of the SSL transaction.

client_key

aliases: key

string

A path to a client key to use as part of the SSL transaction.

cloud

any

Named cloud or cloud config to operate against. If cloud is a string, it references a named cloud config as defined in an OpenStack clouds.yaml file. 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. If cloud is a dict, it contains a complete cloud configuration like would be in a section of clouds.yaml.

ephemeral

string

A string used for filtering flavors based on the amount of ephemeral storage. Format is the same as the ram parameter

interface

aliases: endpoint_type

string

Endpoint URL type to fetch from the service catalog.

Choices:

  • "admin"

  • "internal"

  • "public" ← (default)

limit

integer

Limits the number of flavors returned. All matching flavors are returned by default.

name

string

A flavor name. Cannot be used with ram or vcpus or ephemeral.

ram

string

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

string

Name of the region.

sdk_log_level

string

Log level of the OpenStackSDK

Choices:

  • "INFO" ← (default)

  • "DEBUG"

sdk_log_path

string

Path to the logfile of the OpenStackSDK. If empty no log is written

timeout

integer

How long should ansible wait for the requested resource.

Default: 180

validate_certs

aliases: verify

boolean

Whether or not SSL API requests should be verified.

Before Ansible 2.3 this defaulted to yes.

Choices:

  • false

  • true

vcpus

string

A string used for filtering flavors based on the number of virtual CPUs desired. Format is the same as the ram parameter.

wait

boolean

Should ansible wait until the requested resource is complete.

Choices:

  • false

  • true ← (default)

Notes

Note

  • The result contains a list of unsorted flavors.

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

  • Auth information is driven by openstacksdk, 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 https://docs.openstack.org/openstacksdk/

Examples

# Gather information about all available flavors
- openstack.cloud.compute_flavor_info:
    cloud: mycloud
  register: result

- debug:
    msg: "{{ result.openstack_flavors }}"

# Gather information for the flavor named "xlarge-flavor"
- openstack.cloud.compute_flavor_info:
    cloud: mycloud
    name: "xlarge-flavor"

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

# Get all flavors that have 1024 MB or more of RAM.
- openstack.cloud.compute_flavor_info:
    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.
- openstack.cloud.compute_flavor_info:
    cloud: mycloud
