Synopsis

Manages F5 BIG-IP LTM pool members via the REST API.

Parameters

Parameter		Choices/Defaults	Comments
address string			IP address of the pool member. This can be either IPv4 or IPv6. When creating a new pool member, one of either `address` or `fqdn` must be provided. This parameter cannot be updated after it is set. aliases: ip, host
aggregate list / elements=dictionary			List of 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 strong advise you run the module in `check` mode to ensure basic validation prior to executing this module. aliases: members
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. Specifying an empty string will remove the monitors and revert to inheriting from the pool (default). Specifying `none` will remove any health monitoring from the member completely.
	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 `all` is used.
	type string / required	Choices: all at_least	Monitor rule type when `monitors` is specified. When creating a new pool, if this value is not specified, the default of `all` will be used.
connection_limit integer			Pool member connection limit. Setting this to `0` disables the limit.
description string			Pool member description.
fqdn string			FQDN name of the pool member. This can be any name that is a valid RFC 1123 DNS name. Therefore, the only characters that can be used are "A" to "Z", "a" to "z", "0" to "9", the hyphen ("-") and the period ("."). FQDN names must include at least one period; delineating the host from the domain. For example, `host.domain`. FQDN names must end with a letter or a number. When creating a new pool member, one of either `address` or `fqdn` must be provided. This parameter cannot be updated after it is set. aliases: hostname
fqdn_auto_populate boolean		Choices: no yes	Specifies whether the system automatically creates ephemeral nodes using the IP addresses returned by the resolution of a DNS query for a node defined by an FQDN. When `yes`, the system generates an ephemeral node for each IP address returned in response to a DNS query for the FQDN of the node. Additionally, when a DNS response indicates the IP address of an ephemeral node no longer exists, the system deletes the ephemeral node. When `no`, the system resolves a DNS query for the FQDN of the node with the single IP address associated with the FQDN. When creating a new pool member, the default for this parameter is `yes`. Once set this parameter cannot be changed afterwards. This parameter is ignored when `reuse_nodes` is `yes`.
ip_encapsulation string			Specifies the IP encapsulation using either IPIP (IP encapsulation within IP, RFC 2003) or GRE (Generic Router Encapsulation, RFC 2784) on outbound packets (from BIG-IP system to server-pool member). When `none`, disables IP encapsulation. When `inherit`, inherits the IP encapsulation setting from the member's pool. When any other value, the options are None, Inherit from Pool, and Member Specific.
monitors list / elements=string			Specifies the health monitors the system currently uses to monitor this resource.
name string			Name of the node to create, or re-use, when creating a new pool member. This parameter is optional. If not specified, a node name will be created automatically from either the specified `address` or `fqdn`. The `enabled` state is an alias of `present`.
partition string		Default: "Common"	Partition to manage resources on.
pool string / required			Pool name. This pool must exist.
port integer			Pool member port. This value cannot be changed after it has been set.
preserve_node boolean		Choices: no yes	When state is `absent`, the system attempts to remove the node the pool member references. The node will not be removed if it is still referenced by other pool members. If this happens, the module will not raise an error. Setting this to `yes` disables this behavior.
priority_group integer			Specifies a number representing the priority group for the pool member. When adding a new member, the default is `0`, meaning the member has no priority. To specify a priority, you must activate priority group usage when you create a new pool or when adding or removing pool members. When activated, the system load balances traffic according to the priority group number assigned to the pool member. The higher the number, the higher the priority. So a member with a priority of 3 has higher priority than a member with a priority of 1.
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`.
rate_limit integer			Pool member rate limit (connections-per-second). Setting this to `0` disables the limit.
ratio integer			Pool member ratio weight. Valid values range from 1 through 100. New pool members -- unless overridden with this value -- default to 1.
replace_all_with boolean		Choices: 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
reuse_nodes boolean		Choices: no yes ←	Reuses node definitions if requested.
state string		Choices: present ← absent enabled disabled forced_offline	Pool member state.

Notes

Note

In previous versions of this module which used the SDK, the name parameter would act as fqdn if address or fqdn were not provided.
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.
