New in version 2.8.


Synopsis

  • Manage DNS resolver on a BIG-IP.

Parameters

  • yes

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 no, meaning that the system passes along the DNS queries for the default zones.

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.

string / required

Specifies the name of the DNS resolver.

Default:

"Common"

Device partition to manage resources on.

password

aliases: pass, pwd

provider

dictionary

added in 2.5

A dict object containing connection details.

password

string / required

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

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 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.

    name: resolver1
    provider:
      password: secret
      server: lb.mydomain.com
