openstack.cloud.subnet – Add/Remove subnet to an OpenStack network

Note

This plugin is part of the openstack.cloud collection (version 1.2.1).

To install it use: ansible-galaxy collection install openstack.cloud.

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


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 >= 3.6

Parameters

Parameter Choices/Defaults Comments

allocation_pool_end

string

From the subnet pool the last IP that should be assigned to the virtual machines.

allocation_pool_start

string

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, 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

string

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


aliases: cacert

cidr

string

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 / elements=string

List of DNS nameservers for this subnet.

enable_dhcp

boolean

  • no
  • yes

Whether DHCP should be enabled for this subnet.

extra_specs

dictionary

Default:

{}

Dictionary with extra key/value pairs passed to the API

gateway_ip

string

The ip that would be assigned to the gateway for this subnet

host_routes

list / elements=dictionary

A list of host route dictionaries for the subnet.

destination

string / required

The destination network (CIDR).

nexthop

string / required

The next hop (aka gateway) for the destination.

interface

string

  • admin
  • internal
  • public

Endpoint URL type to fetch from the service catalog.


aliases: endpoint_type

ip_version

string

  • 4
  • 6

Default:

4

The IP version of the subnet 4 or 6

ipv6_address_mode

string

  • dhcpv6-stateful
  • dhcpv6-stateless
  • slaac

IPv6 address mode

ipv6_ra_mode

string

  • dhcpv6-stateful
  • dhcpv6-stateless
  • slaac

IPv6 router advertisement mode

name

string / 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

string

Name of the network to which the subnet should be attached

Required when state is 'present'

no_gateway_ip

boolean

  • no

  • yes

The gateway IP would not be assigned for this subnet

project

string

Project name or ID containing the subnet (name admin-only)

region_name

string

Name of the region.

state

string

  • 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

  • no

  • yes

Use the default subnetpool for ip_version to obtain a CIDR.

validate_certs

boolean

  • no

  • yes

Whether or not SSL API requests should be verified.

Before Ansible 2.3 this defaulted to yes.


aliases: verify

wait

boolean

  • 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/
