f5networks.f5_modules.bigip_profile_dns – Manage DNS profiles on a BIG-IP

Note

This plugin is part of the f5networks.f5_modules collection.

To install it use: ansible-galaxy collection install f5networks.f5_modules.

To use it in a playbook, specify: f5networks.f5_modules.bigip_profile_dns.

New in version 1.0.0: of f5networks.f5_modules

Synopsis

  • Manage DNS profiles on a BIG-IP. There are many DNS profiles options, each with their own adjustments to the standard dns profile. Users of this module should be aware that many of the configurable options have no module default. Instead, the default is assigned by the BIG-IP system itself which, in most cases, is acceptable.

Parameters

Parameter Choices/Defaults Comments
cache_name
string
Specifies the user-created cache the system uses to cache DNS responses.
When you select a cache for the system to use, you must also set enable_dns_cache to yes
enable_cache
boolean
    Choices:
  • no
  • yes
Specifies whether the system caches DNS responses.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
When yes, the BIG-IP system caches DNS responses handled by the virtual servers associated with this profile. When you enable this setting, you must also specify a value for cache_name.
When no, the BIG-IP system does not cache DNS responses handled by the virtual servers associated with this profile. However, the profile retains the association with the DNS cache in the cache_name parameter. Disable this setting when you want to debug the system.
enable_dns_express
boolean
    Choices:
  • no
  • yes
Specifies whether the DNS Express engine is enabled.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
The DNS Express engine receives zone transfers from the authoritative DNS server for the zone. If the enable_zone_transfer setting is also yes on this profile, the DNS Express engine also responds to zone transfer requests made by the nameservers configured as zone transfer clients for the DNS Express zone.
enable_dns_firewall
boolean
    Choices:
  • no
  • yes
Specifies whether the DNS firewall is enabled.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
enable_dnssec
boolean
    Choices:
  • no
  • yes
Specifies whether the system signs responses with DNSSEC keys and replies to DNSSEC specific queries (for example, DNSKEY query type).
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
enable_gtm
boolean
    Choices:
  • no
  • yes
Specifies whether the system uses Global Traffic Manager (now BIG-IP DNS) to manage the response.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
enable_zone_transfer
boolean
    Choices:
  • no
  • yes
Specifies whether the system answers zone transfer requests for a DNS zone created on the system.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
The enable_dns_express and enable_zone_transfer settings on a DNS profile affect how the system responds to zone transfer requests.
When the enable_dns_express and enable_zone_transfer settings are both yes, if a zone transfer request matches a DNS Express zone, DNS Express answers the request.
When the enable_dns_express setting is no and the enable_zone_transfer setting is yes, the BIG-IP system processes zone transfer requests based on the last action and answers the request from local BIND or a pool member.
name
string / required
Specifies the name of the DNS profile.
parent
string
Specifies the profile from which this profile inherits settings.
When creating a new profile, if this parameter is not specified, the default is the system-supplied dns profile.
partition
string
Default:
"Common"
Device partition to manage resources on.
process_recursion_desired
boolean
    Choices:
  • no
  • yes
Specifies whether to process client-side DNS packets with Recursion Desired set in the header.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
If set to no, processing of the packet is subject to the unhandled-query-action option.
provider
dictionary
added in 1.0.0 of f5networks.f5_modules
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
    Choices:
  • no
  • yes
If yes, TEEM telemetry data is not sent to F5.
You may omit this option by setting the environment variable F5_TEEM.
password
string / required
The password for the user account used to connect to the BIG-IP.
You may omit this option by setting the environment variable F5_PASSWORD.

aliases: pass, pwd
server
string / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
integer
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
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
    Choices:
  • rest ←
Configures the transport connection to use when connecting to the remote device.
user
string / required
The username to connect to the BIG-IP with. This user must have administrative privileges on the device.
You may omit this option by setting the environment variable F5_USER.
validate_certs
boolean
    Choices:
  • no
  • yes ←
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.
state
string
    Choices:
  • present ←
  • absent
When present, ensures the profile exists.
When absent, ensures the profile is removed.
unhandled_query_action
string
    Choices:
  • allow
  • drop
  • reject
  • hint
  • no-error
Specifies the action to take when a query does not match a Wide IP or a DNS Express Zone.
When allow, the BIG-IP system forwards queries to a DNS server or pool member. If a pool is not associated with a listener and the Use BIND Server on BIG-IP setting is set to Enabled, requests are forwarded to the local BIND server.
When drop, the BIG-IP system does not respond to the query.
When reject, the BIG-IP system returns the query with the REFUSED return code.
When hint, the BIG-IP system returns the query with a list of root name servers.
When no-error, the BIG-IP system returns the query with the NOERROR return code.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.
use_local_bind
boolean
    Choices:
  • no
  • yes
Specifies whether the system forwards non-wide IP queries to the local BIND server on the BIG-IP system.
For best performance, disable this setting when using a DNS cache.
When creating a new profile, if this parameter is not specified, the default is provided by the parent profile.

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.
