f5networks.f5_modules.bigip_gtm_pool_member – Manage GTM pool member settings

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_gtm_pool_member.

New in version 1.0.0: of f5networks.f5_modules

Synopsis

  • Manages a variety of settings on GTM 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 it is strongly advised to 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
    Choices:
  • no
  • yes
Whether the bits limit it 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, in bits per second, for the member.
If the network traffic volume exceeds this limit, the system marks the member as unavailable.
connections_enabled
boolean
    Choices:
  • no
  • yes
Whether the current connections limit it 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 member.
If the connections exceed this limit, the system marks the server as unavailable.
packets_enabled
boolean
    Choices:
  • no
  • yes
Whether the packets limit it 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, in packets per second, for the member.
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.
When creating a new pool member, if this parameter is not specified, 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.
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.
ratio
integer
Specifies the weight of the pool member for load balancing purposes.
replace_all_with
boolean
    Choices:
  • no ←
  • yes
Remove members not defined in the aggregate parameter.
This operation is all or none, meaning that 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
    Choices:
  • present ←
  • absent
  • enabled
  • disabled
Pool member state. When present, ensures that the pool member is created and enabled. When absent, ensures that the pool member is removed from the system. When enabled or disabled, ensures that the pool member is enabled or disabled (respectively) on the remote device.
It is recommended that you use the members parameter of the bigip_gtm_pool module when adding and removing members and it provides an easier way of specifying order. If this is not possible, then 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
    Choices:
  • 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.
