## Synopsis

- Manages F5 BIG-IP LTM pool members via iControl SOAP API.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
address string added in 2.2 |  | 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 added in 2.8 |  | List of pool member definitions to be created, modified or removed. aliases: members
availability_requirements dictionary added in 2.8 |  | Specifies, if you activate more than one health monitor, 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 pool (default). Specifying `none` value 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 | 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 added in 2.6 |  | 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 lease one period; delineating the host from the domain. ex. `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 added in 2.6 | 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 added in 2.8 |  | 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 IP encapsulation setting from the member's pool. When any other value, Options are None, Inherit from Pool, and Member Specific.
monitors list added in 2.8 |  | Specifies the health monitors that the system currently uses to monitor this resource.
name string added in 2.6 |  | Name of the node to create, or re-use, when creating a new pool member. This parameter is optional and, 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.
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
pool string / required |  | Pool name. This pool must exist.
port integer / required |  | Pool member port. This value cannot be changed after it has been set.
preserve_node boolean added in 2.1 | Choices: no yes | When state is `absent` attempts to remove the node that 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 added in 2.5 |  | Specifies a number representing the priority group for the pool member. When adding a new member, the default is 0, meaning that 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 2.5 |  | A dict object containing connection details.
| 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`.
| ssh_keyfile path |  | Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. You may omit this option by setting the environment variable `ANSIBLE_NET_SSH_KEYFILE`.
| timeout integer | Default: 10 | 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: cli 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 added in 2.8 | 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
reuse_nodes boolean added in 2.6 | Choices: no yes ← | Reuses node definitions if requested.
server string / required |  | The BIG-IP host. You may omit this option by setting the environment variable `F5_SERVER`.
server_port integer added in 2.2 | Default: 443 | The BIG-IP server port. You may omit this option by setting the environment variable `F5_SERVER_PORT`.
state string / required | Choices: present ← absent enabled disabled forced_offline | Pool member state.
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 added in 2.0 | 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`.

## 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 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.
