f5networks.f5_modules.bigip_pool module – Manages F5 BIG-IP LTM pools

Note

This module is part of the f5networks.f5_modules collection (version 1.25.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install f5networks.f5\_modules.

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

New in f5networks.f5_modules 1.0.0

Synopsis

• Manages F5 BIG-IP LTM pools via iControl REST API.

Parameters

Parameter	Comments
aggregate aliases: pools list / elements=dictionary	List of pool 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 which changes were made prior to failure. Therefore we strongly advise you run the module in check mode to ensure basic validation prior to executing this module.
description string	Specifies descriptive text that identifies the pool.
lb_method string	Load balancing method. When creating a new pool, if this value is not specified, the default of round-robin is used. Choices: "dynamic-ratio-member" "dynamic-ratio-node" "fastest-app-response" "fastest-node" "least-connections-member" "least-connections-node" "least-sessions" "observed-member" "observed-node" "predictive-member" "predictive-node" "ratio-least-connections-member" "ratio-least-connections-node" "ratio-member" "ratio-node" "ratio-session" "round-robin" "weighted-least-connections-member" "weighted-least-connections-node"
metadata any	Arbitrary key/value pairs you can attach to a pool. This is useful in situations where you might want to annotate a pool to be managed by Ansible. Key names are stored as strings; this includes names that are numbers. Values for all of the keys are stored as strings; this includes values that are numbers. Data will be persisted, not ephemeral.
min_up_members integer	Specifies the minimum number of pool members that must be up, otherwise, the system takes the action specified in the min-up-members-action option. Use this option for gateway pools in a redundant system where a unit number is applied to the pool. This indicates the pool is configured only on the specified unit. When creating a new pool, if this parameter is not specified, the default is 0.
min_up_members_action string	Specifies the action to take if min_up_members_checking is enabled and the number of active pool members falls below the number specified in the min_up_members option. When creating a new pool, if this parameter is not specified, the default is failover. Choices: "failover" "reboot" "restart-all"
min_up_members_checking string	Enables or disables the min_up_members feature. If you enable this feature, you must also specify a value for both the min_up_members and min_up_members_action options. When creating a new pool, if this parameter is not specified, the default is disabled. Choices: "enabled" "disabled"
monitor_type aliases: availability_requirements_type string	Monitor rule type when monitors is specified. When creating a new pool, if this value is not specified, the default of and_list is used. When single, ensures all specified monitors are checked, but additionally includes checks to make sure you only specified a single monitor. When and_list, ensures all monitors are checked. When m_of_n, ensures quorum of monitors are checked. m_of_n requires a quorum of 1 or greater be set either in the playbook, or already exist on the device. Both single and and_list are functionally identical, as BIG-IP considers all monitors as “a list”. Choices: "and_list" "m_of_n" "single"
monitors list / elements=string	Monitor template name list. If the partition is not provided as part of the monitor name, the partition option is used instead.
name aliases: pool string	Pool name
partition string	Device partition to manage resources on. Default: "Common"
priority_group_activation aliases: minimum_active_members integer	Specifies whether the system load balances traffic according to the priority number assigned to the pool member. When creating a new pool, if this parameter is not specified, the default of 0 is used. To disable this setting, provide the value 0. Once you enable this setting, you can specify pool member priority when you create a new pool or on a pool member’s properties screen. The system treats same-priority pool members as a group. To enable priority group activation, provide a number from 0 to 65535 that represents the minimum number of members that must be available in one priority group before the system directs traffic to members in a lower priority group. When a sufficient number of members become available in the higher priority group, the system again directs traffic to the higher priority group.
provider dictionary added in f5networks.f5_modules 1.0.0	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. Choices: false ← (default) true
password aliases: pass, pwd 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.
server string / required	The BIG-IP host. You may omit this option by setting the environment variable F5_SERVER.
server_port integer	The BIG-IP server port. You may omit this option by setting the environment variable F5_SERVER_PORT. Default: 443
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	Configures the transport connection to use when connecting to the remote device. Choices: "rest" ← (default)
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	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. Choices: false true ← (default)
quorum aliases: availability_requirements_at_least integer	Monitor quorum value when monitor_type is m_of_n. Quorum must be a value of 1 or greater when monitor_type is m_of_n.
replace_all_with aliases: purge boolean	Removes pools not defined in the aggregate parameter. This operation is all or none, meaning it will stop if there are some pools that cannot be removed. Choices: false ← (default) true
reselect_tries integer	Sets the number of times the system tries to contact a pool member after a passive failure.
service_down_action string	Sets the action to take when node goes down in pool. Choices: "none" "reset" "drop" "reselect"
slow_ramp_time integer	Sets the ramp-up time (in seconds) to gradually ramp up the load on newly added or freshly detected up pool members.
state string	When present, guarantees the pool exists with the provided attributes. When absent, removes the pool from the system. Choices: "absent" "present" ← (default)

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.
