os_subnets_facts - Retrieve facts about one or more OpenStack subnets.

New in version 2.0.

Synopsis

  • Retrieve facts about one or more subnets from OpenStack.

Requirements

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

  • openstacksdk
  • python >= 2.7

Parameters

Parameter Choices/Defaults Comments
api_timeout
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 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
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
Ignored. Present for backwards compatibility
cacert
A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
cert
A path to a client certificate to use as part of the SSL transaction.
cloud
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.
filters
A dictionary of meta data to use for further filtering. Elements of this dictionary may be additional dictionaries.
interface
(added in 2.3)
    Choices:
  • public ←
  • internal
  • admin
Endpoint URL type to fetch from the service catalog.

aliases: endpoint_type
key
A path to a client key to use as part of the SSL transaction.
region_name
Name of the region.
subnet
Name or ID of the subnet
timeout Default:
180
How long should ansible wait for the requested resource.
verify
bool
    Choices:
  • no
  • yes
Whether or not SSL API requests should be verified. Before 2.3 this defaulted to True.

aliases: validate_certs
wait
bool
    Choices:
  • no
  • yes ←
Should ansible wait until the requested resource is complete.

Notes

Note

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