os_subnet - Add/Remove subnet to an OpenStack network

New in version 2.0.

Synopsis

Add or Remove a subnet to an OpenStack network

Requirements (on host that executes module)

  • python >= 2.6
  • python >= 2.7
  • shade

Options

parameter required default choices comments
allocation_pool_end
no None
From the subnet pool the last IP that should be assigned to the virtual machines.
allocation_pool_start
no None
From the subnet pool the starting address from which the IP should be allocated.
api_timeout
no None
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
no
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
no password
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
no
Name of the availability zone.
cacert
no None
A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
cert
no None
A path to a client certificate to use as part of the SSL transaction.
cidr
no None
The CIDR representation of the subnet that should be assigned to the subnet. Required when state is 'present'
cloud
no
Named cloud to operate against. 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.
dns_nameservers
no None
List of DNS nameservers for this subnet.
enable_dhcp
no True
Whether DHCP should be enabled for this subnet.
endpoint_type
no public
  • public
  • internal
  • admin
Endpoint URL type to fetch from the service catalog.
gateway_ip
no None
The ip that would be assigned to the gateway for this subnet
host_routes
no None
A list of host route dictionaries for the subnet.
ip_version
no 4
The IP version of the subnet 4 or 6
ipv6_address_mode
no None
  • dhcpv6-stateful
  • dhcpv6-stateless
  • slaac
IPv6 address mode
ipv6_ra_mode
no None
  • dhcpv6-stateful
  • dhcpv6-stateless
  • slaac
IPv6 router advertisement mode
key
no None
A path to a client key to use as part of the SSL transaction.
name
yes
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
no
Name of the network to which the subnet should be attached
Required when state is 'present'
no_gateway_ip
(added in 2.2)
no
The gateway IP would not be assigned for this subnet
project
(added in 2.1)
no None
Project name or ID containing the subnet (name admin-only)
region_name
no
Name of the region.
state
no present
  • present
  • absent
Indicate desired state of the resource
timeout
no 180
How long should ansible wait for the requested resource.
validate_certs
no True
Whether or not SSL API requests should be verified.
aliases: verify
wait
no yes
  • yes
  • no
Should ansible wait until the requested resource is complete.

Examples

# Create a new (or update an existing) subnet on the specified network
- os_subnet:
    state: present
    network_name: network1
    name: net1subnet
    cidr: 192.168.0.0/24
    dns_nameservers:
       - 8.8.8.7
       - 8.8.8.8
    host_routes:
       - destination: 0.0.0.0/0
         nexthop: 12.34.56.78
       - destination: 192.168.0.0/24
         nexthop: 192.168.0.1

# Delete a subnet
- os_subnet:
    state: absent
    name: net1subnet

# Create an ipv6 stateless subnet
- os_subnet:
    state: present
    name: intv6
    network_name: internal
    ip_version: 6
    cidr: 2db8:1::/64
    dns_nameservers:
        - 2001:4860:4860::8888
        - 2001:4860:4860::8844
    ipv6_ra_mode: dhcpv6-stateless
    ipv6_address_mode: dhcpv6-stateless

Notes

Note

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

Note

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
