alternate_lb_method

string

The load balancing mode the system tries if the preferred_lb_method is unsuccessful in picking a pool.

Choices:

  • round-robin

  • return-to-dns

  • none

  • ratio

availability_requirements

dictionary

If you activate more than one health monitor, specifies the number of health monitors that must receive successful responses in order for the link to be considered available.

at_least

integer

Specifies the minimum number of active health monitors that must be successful before the link is considered up.

This parameter is only relevant when a type of at_least is used.

This parameter will be ignored if a type of either all or require is used.

number_of_probers

integer

Specifies the number of probers that should be used when running probes.

When creating a new virtual server, if this parameter is specified, the number_of_probes parameter must also be specified.

The value of this parameter should always be higher than, or equal to, the value of number_of_probers.

This parameter is only relevant when a type of require is used.

This parameter will be ignored if a type of either all or at_least is used.

number_of_probes

integer

Specifies the minimum number of probes that must succeed for this server to be declared up.

When creating a new virtual server, if this parameter is specified, the number_of_probers parameter must also be specified.

The value of this parameter should always be lower than, or equal to, the value of number_of_probers.

This parameter is only relevant when a type of require is used.

This parameter will be ignored if a type of either all or at_least is used.

type

When creating a new pool, if this value is not specified, the default of ‘all’ will be used.

Choices:

  • all

  • at_least

  • require

fallback_ip

string

Specifies the IPv4 or IPv6 address of the server to which the system directs requests when it cannot use one of its pools to do so. Note that the system uses the fallback IP only if you select the fallback_ip load balancing method.

fallback_lb_method

string

The load balancing mode the system tries if both the preferred_lb_method and alternate_lb_methods are unsuccessful in picking a pool.

Choices:

  • round-robin

  • return-to-dns

  • ratio

  • topology

  • static-persistence

  • global-availability

  • none

max_answers_returned

integer

Specifies the maximum number of available virtual servers the system lists in a response.

The maximum is 500.

members

list / elements=dictionary

Members to assign to the pool.

The order of the members in this list is the order they will be listed in the pool.

server

string / required

Name of the server which the pool member is a part of.

virtual_server

string / required

Name of the virtual server, associated with the server, the pool member is a part of.

monitors

list / elements=string

Specifies the health monitors the system currently uses to monitor this resource.

When availability_requirements.type is require, you may only have a single monitor in the monitors list.

name

string / required

Name of the GTM pool.

partition

string

Device partition to manage resources on.

Default: “Common”

preferred_lb_method

string

The load balancing mode the system tries first.

Choices:

  • round-robin

  • return-to-dns

  • ratio

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

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.

integer

The BIG-IP server port.

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

user

string / required

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

  • yes ← (default)

state

string

Choices:

  • present ← (default)

  • absent

  • enabled

  • disabled

ttl

integer

Specifies the number of seconds the IP address, once found, is valid.

type

string / required

The type of GTM pool you want to create.

Choices:

  • a

  • aaaa

  • cname

  • mx

  • naptr

  • srv

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.
