Synopsis

  • Manage DNS resolvers on a BIG-IP system.

Parameters

Parameter

Comments

answer_default_zones

boolean

Specifies whether the system answers DNS queries for the default zones localhost, reverse 127.0.0.1 and ::1, and AS112.

When creating a new resolver, if this parameter is not specified, the default is false, meaning the system passes along the DNS queries for the default zones.

Choices:

  • false

  • true

cache_size

integer

Specifies the size of the internal DNS resolver cache.

When creating a new resolver, if this parameter is not specified, the default is 5767168 bytes.

After the cache reaches this size, when new or refreshed content arrives, the system removes expired and older content and caches the new or updated content.

name

string / required

Specifies the name of the DNS resolver.

partition

string

Device partition to manage resources on.

Default: "Common"

provider

dictionary

added in f5networks.f5_modules 1.0.0

A dict object containing connection details.

auth_provider

string

Configures the auth provider for to obtain authentication tokens from the remote device.

This option is really used when working with BIG-IQ devices.

no_f5_teem

boolean

If yes, TEEM telemetry data is not sent to F5.

You may omit this option by setting the environment variable F5_TELEMETRY_OFF.

Previously used variable F5_TEEM is deprecated as its name was confusing.

Choices:

  • false ← (default)

  • true

password

aliases: pass, pwd

string / required

The password for the user account used to connect to the BIG-IP or the BIG-IQ.

You may omit this option by setting the environment variable F5_PASSWORD.

server

string / required

The BIG-IP host or the BIG-IQ host.

You may omit this option by setting the environment variable F5_SERVER.

server_port

integer

The BIG-IP server port.

You may omit this option by setting the environment variable F5_SERVER_PORT.

Default: 443

timeout

integer

Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.

transport

string

Configures the transport connection to use when connecting to the remote device.

Choices:

  • "rest" ← (default)

user

string / required

The username to connect to the BIG-IP or the BIG-IQ. This user must have administrative privileges on the device.

You may omit this option by setting the environment variable F5_USER.

validate_certs

boolean

If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.

You may omit this option by setting the environment variable F5_VALIDATE_CERTS.

Choices:

route_domain

integer

Specifies the route domain the resolver uses for outbound traffic.

state

string

When present, ensures the resource exists.

  • "absent"

use_ipv4

boolean

Specifies whether the system can use IPv4 to query backend nameservers.

An IPv4 Self IP and default route must be available for these queries to work successfully.

When creating a new resolver, if this parameter is not specified, the default is true.

Choices:

  • false

  • true

use_ipv6

boolean

Specifies whether the system can use IPv6 to query backend nameservers.

An IPv6 Self IP and default route must be available for these queries to work successfully.

When creating a new resolver, if this parameter is not specified, the default is true.

Choices:

  • true

use_tcp

boolean

Specifies whether the system answers and issues TCP-formatted queries.

When creating a new resolver, if this parameter is not specified, the default is true.

Notes

Note

  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.

  • Requires BIG-IP software version >= 12.

  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the f5networks.f5_modules.bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
