f5networks.f5_modules.bigip_gtm_pool_member – Manage GTM pool member settings

Note

This plugin is part of the f5networks.f5_modules collection (version 1.6.0).

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

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


New in version 1.0.0: of f5networks.f5_modules


Synopsis

  • Manages a variety of settings on GTM (now BIG-IP DNS) pool members. The settings that can be adjusted with this module are much more broad that what can be done in the bigip_gtm_pool module. The pool module is intended to allow you to adjust the member order in the pool, not the various settings of the members. The bigip_gtm_pool_member module should be used to adjust all of the other settings.

Parameters

Parameter Choices/Defaults Comments

aggregate

list / elements=dictionary

List of GTM pool member definitions to be created, modified, or removed.

When using aggregates, if one of the aggregate definitions is invalid, the aggregate run will fail, indicating the error it last encountered.

The module will NOT rollback any changes it has made prior to encountering the error.

The module also will not indicate what changes were made prior to failure, therefore we strongly advise you run the module in check mode to make basic validation, prior to module execution.


aliases: members

description

string

The description of the pool member.

limits

dictionary

Specifies resource thresholds or limit requirements at the pool member level.

When you enable one or more limit settings, the system then uses that data to take members in and out of service.

You can define limits for any or all of the limit settings. However, when a member does not meet the resource threshold limit requirement, the system marks the member as unavailable and directs load balancing traffic to another resource.

bits_enabled

boolean

  • no
  • yes

Whether the bits limit is enabled or not.

This parameter allows you to switch on or off the effect of the limit.

bits_limit

integer

Specifies the maximum allowable data throughput rate for the member, in bits per second.

If the network traffic volume exceeds this limit, the system marks the member as unavailable.

connections_enabled

boolean

  • no
  • yes

Whether the current connections limit is enabled or not.

This parameter allows you to switch on or off the effect of the limit.

connections_limit

integer

Specifies the maximum number of concurrent connections, combined, for all of the members.

If the connections exceed this limit, the system marks the server as unavailable.

packets_enabled

boolean

  • no
  • yes

Whether the packets limit is enabled or not.

This parameter allows you to switch on or off the effect of the limit.

packets_limit

integer

Specifies the maximum allowable data transfer rate for the member, in packets per second.

If the network traffic volume exceeds this limit, the system marks the member as unavailable.

member_order

integer

Specifies the order in which the member will appear in the pool.

The system uses this number with load balancing methods that involve prioritizing pool members, such as the Ratio load balancing method.

When creating a new member using this module, if the member_order parameter is not specified, it will default to 0 (first member in the pool).

monitor

string

Specifies the monitor assigned to this pool member.

Pool members only support a single monitor.

If the port of the gtm_virtual_server is *, the accepted values of this parameter will be affected.

If this parameter is not specified when creating a new pool member, the default of default will be used.

To remove the monitor from the pool member, use the value none.

For pool members created on different partitions, you can also specify the full path to the Common monitor. For example, /Common/tcp.

partition

string

Default:

"Common"

Device partition to manage resources on.

pool

string / required

Name of the GTM pool.

For pools created on different partitions, you must specify partition of the pool in the full path format, for example, /FooBar/pool_name.

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

  • 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

  • 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

  • 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.

ratio

integer

Specifies the weight of the pool member for load balancing purposes.

replace_all_with

boolean

  • no ←

  • yes

Removes members not defined in the aggregate parameter.

This operation is all or none, meaning it will stop if there are some pool members that cannot be removed.


aliases: purge

server_name

string

Specifies the GTM server which contains the virtual_server.

state

string

  • present ←

  • absent
  • enabled
  • disabled

Pool member state. When present, ensures the pool member is created and enabled. When absent, ensures the pool member is removed from the system. When enabled or disabled, ensures the pool member is enabled or disabled (respectively) on the remote device.

We recommend you use the members parameter of the bigip_gtm_pool module when adding and removing members, as it provides an easier way of specifying order. If this is not possible, the state parameter here should be used.

Remember that the order of the members will be affected if you add or remove them using this method. To some extent, this can be controlled using the member_order parameter.

type

string / required

  • a
  • aaaa
  • cname
  • mx
  • naptr
  • srv

The type of GTM pool that the member is in.

virtual_server

string

Specifies the name of the GTM virtual server which is assigned to the specified server.



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.
