Synopsis

Retrieve information about one or more subnets from OpenStack.
This module was called os_subnets_facts before Ansible 2.9, returning ansible_facts. Note that the os_subnets_info module no longer returns ansible_facts!

Aliases: os_subnets_facts

Requirements

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

openstacksdk
openstacksdk >= 0.12.0
python >= 2.7

Parameters

Parameter	Choices/Defaults	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, os_user_domain_name or os_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 -		Ignored. Present for backwards compatibility
ca_cert string		A path to a CA Cert bundle that can be used as part of verifying SSL API requests. aliases: cacert
client_cert string		A path to a client certificate to use as part of the SSL transaction. aliases: cert
client_key string		A path to a client key to use as part of the SSL transaction. aliases: key
cloud raw		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 string	Choices: admin internal public ←	Endpoint URL type to fetch from the service catalog. aliases: endpoint_type
name -		Name or ID of the subnet. Alias 'subnet' added in version 2.8. aliases: subnet
region_name string		Name of the region.
timeout integer	Default: 180	How long should ansible wait for the requested resource.
validate_certs boolean	Choices: no ← yes	Whether or not SSL API requests should be verified. Before Ansible 2.3 this defaulted to `yes`. aliases: verify
wait boolean	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 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/
