os_subnet – Add/Remove subnet to an OpenStack network

Synopsis

  • Add or Remove a subnet to an OpenStack network

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
allocation_pool_end
-
From the subnet pool the last IP that should be assigned to the virtual machines.
allocation_pool_start
-
From the subnet pool the starting address from which the IP should be allocated.
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
cidr
-
The CIDR representation of the subnet that should be assigned to the subnet. Required when state is 'present' and a subnetpool is not specified.
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.
dns_nameservers
-
List of DNS nameservers for this subnet.
enable_dhcp
boolean
    Choices:
  • no
  • yes ←
Whether DHCP should be enabled for this subnet.
extra_specs
-
added in 2.7
 Default:
{}
Dictionary with extra key/value pairs passed to the API
gateway_ip
-
The ip that would be assigned to the gateway for this subnet
host_routes
-
A list of host route dictionaries for the subnet.
interface
string
    Choices:
  • admin
  • internal
  • public ←
Endpoint URL type to fetch from the service catalog.

aliases: endpoint_type
ip_version
-
Default:
4
The IP version of the subnet 4 or 6
ipv6_address_mode
-
    Choices:
  • dhcpv6-stateful
  • dhcpv6-stateless
  • slaac
IPv6 address mode
ipv6_ra_mode
-
    Choices:
  • dhcpv6-stateful
  • dhcpv6-stateless
  • slaac
IPv6 router advertisement mode
name
- / required
The name of the subnet that should be created. Although Neutron allows for non-unique subnet names, this module enforces subnet name uniqueness.
network_name
-
Name of the network to which the subnet should be attached
Required when state is 'present'
no_gateway_ip
boolean
    Choices:
  • no ←
  • yes
The gateway IP would not be assigned for this subnet
project
-
Project name or ID containing the subnet (name admin-only)
region_name
string
Name of the region.
state
-
    Choices:
  • present ←
  • absent
Indicate desired state of the resource
timeout
integer
Default:
180
How long should ansible wait for the requested resource.
use_default_subnetpool
boolean
    Choices:
  • no ←
  • yes
Use the default subnetpool for ip_version to obtain a CIDR.
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/
