Synopsis

  • Manage (create, update or delete) Open Telekom Cloud VPC subnet.

  • openstacksdk

  • openstacksdk >= 0.36.0

  • otcextensions>=0.24.5

  • python >= 3.6

Parameters

Parameter

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

string

Specifies the AZ to which the subnet belongs.

ca_cert

aliases: cacert

string

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

cidr

string

Specifies the subnet CIDR block.

The value must be within the VPC CIDR block.

The value must be in CIDR format. The subnet mask cannot be greater than 28.

client_cert

aliases: cert

string

A path to a client certificate to use as part of the SSL transaction.

client_key

aliases: key

string

A path to a client key to use as part of the SSL transaction.

cloud

any

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.

description

string

Provides supplementary information about the subnet.

The value can contain no more than 255 characters and cannot contain angle brackets (< or >).

dhcp_enable

boolean

Specifies whether DHCP is enabled for the subnet.

The value can be true (enabled) or false (disabled).

If this parameter is left blank, the system automatically sets it to true by default. If this parameter is set to false, newly created ECSs cannot obtain IP addresses, and usernames and passwords cannot be injected using Cloud-init.

Choices:

  • false

  • true

dns_list

aliases: dnsList

list / elements=string

Specifies the DNS server address list of a subnet.

This field is required if use more than two DNS servers.

This parameter value is the superset of both primary_dns and secondary_dns.

extra_dhcp_opts

list / elements=dictionary

Specifies the NTP server address configured for the subnet.

opt_name

string / required

Specifies the NTP server address name configured for the subnet.

Choices:

  • "ntp"

opt_value

string

Specifies the NTP server address configured for the subnet.

The option ntp for opt_name indicates the NTP server configured for the subnet. Currently, only IPv4 addresses are supported. A maximum of four IP addresses can be configured, and each address must be unique. Multiple IP addresses must be separated using commas (,). The option null for opt_name indicates that no NTP server is configured for the subnet. The parameter value cannot be an empty string.

gateway_ip

string

Specifies the gateway of the subnet.

The value must be an IP address in the subnet.

The value must be a valid IP address.

interface

aliases: endpoint_type

string

Endpoint URL type to fetch from the service catalog.

Choices:

  • "admin"

  • "internal"

  • "public" ← (default)

name

string / required

Specifies the subnet name or ID.

When creating a new subnet, the value can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).

primary_dns

string

Specifies the IP address of DNS server 1 on the subnet.

The value must be an IP address.

region_name

string

Name of the region.

sdk_log_level

string

Log level of the OpenStackSDK

Choices:

  • "ERROR"

  • "WARN" ← (default)

  • "INFO"

  • "DEBUG"

sdk_log_path

string

Path to the logfile of the OpenStackSDK. If empty no log is written

secondary_dns

string

Specifies the IP address of DNS server 2 on the subnet.

The value must be an IP address.

state

string

Indicate desired state of the resource.

Choices:

  • "present" ← (default)

  • "absent"

timeout

integer

How long should ansible wait for the requested resource.

Default: 180

validate_certs

aliases: verify

boolean

Whether or not SSL API requests should be verified.

Before Ansible 2.3 this defaulted to yes.

Choices:

  • false

  • true

vpc

aliases: vpc_id

string / required

Specifies the name or ID of the VPC to which the subnet belongs.

wait

boolean

Should ansible wait until the requested resource is complete.

Choices:

  • false

  • true ← (default)

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/
