bigip_pool_member - Manages F5 BIG-IP LTM pool members

New in version 1.4.

Synopsis

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

Requirements

The below requirements are needed on the host that executes this module.

  • f5-sdk >= 3.0.16

Parameters

Parameter Choices/Defaults Comments
address
(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
connection_limit
Pool member connection limit. Setting this to 0 disables the limit.
description
Pool member description.
fqdn
(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
bool

(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.
This parameter is ignored when reuse_nodes is yes.
name
(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 Default:
Common
Partition
password
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
required
Pool name. This pool must exist.
port
required
Pool member port.
This value cannot be changed after it has been set.
preserve_node
bool

(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
(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
(added in 2.5)
Default:
None
A dict object containing connection details.
ssh_keyfile
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 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.
server
required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
user
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.
server_port Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
password
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
validate_certs
bool
    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.
transport
required
    Choices:
  • rest
  • cli ←
Configures the transport connection to use when connecting to the remote device.
rate_limit
Pool member rate limit (connections-per-second). Setting this to 0 disables the limit.
ratio
Pool member ratio weight. Valid values range from 1 through 100. New pool members -- unless overridden with this value -- default to 1.
reuse_nodes
bool

(added in 2.6)
    Choices:
  • no
  • yes ←
Reuses node definitions if requested.
server
required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
(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
required
    Choices:
  • present ←
  • absent
  • enabled
  • disabled
  • forced_offline
Pool member state.
user
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
bool

(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 the f5-sdk Python package on the host. This is as easy as pip install f5-sdk.
  • 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.
