Synopsis

  • Manage DNS resolvers on a BIG-IP system.

  • 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 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.
name
string / required
Specifies the name of the DNS resolver.
partition

"Common"
Device partition to manage resources on.
provider

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.

Examples

    name: resolver1
    provider:
