Synopsis ¶

Manages F5 BIG-IP LTM nodes.

Requirements ¶

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

f5-sdk >= 3.0.9

Parameters ¶

Parameter	Choices/Defaults	Comments
address (added in 2.2)		IP address of the node. This can be either IPv4 or IPv6. When creating a new node, one of either `address` or `fqdn` must be provided. This parameter cannot be updated after it is set. aliases: ip, host
description		Specifies descriptive text that identifies the node.
fqdn (added in 2.5)		FQDN name of the node. 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 node, one of either `address` or `fqdn` must be provided. This parameter cannot be updated after it is set. aliases: hostname
monitor_type (added in 1.3)	Choices: and_list m_of_n single	Monitor rule type when `monitors` is specified. When creating a new pool, if this value is not specified, the default of 'and_list' will be used. Both `single` and `and_list` are functionally identical since BIG-IP considers all monitors as "a list". BIG=IP either has a list of many, or it has a list of one. Where they differ is in the extra guards that `single` provides; namely that it only allows a single monitor.
monitors (added in 2.2)		Specifies the health monitors that the system currently uses to monitor this node.
name required		Specifies the name of the node.
partition (added in 2.5)	Default: Common	Device partition to manage resources on.
password required		The password for the user account used to connect to the BIG-IP. You can omit this option if the environment variable `F5_PASSWORD` is set. aliases: pass, pwd
provider (added in 2.5)		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. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_SSH_KEYFILE` will be used instead.
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 can omit this option if the environment variable `F5_SERVER` is set.
user required		The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You can omit this option if the environment variable `F5_USER` is set.
server_port	Default: 443	The BIG-IP server port. You can omit this option if the environment variable `F5_SERVER_PORT` is set.
password required		The password for the user account used to connect to the BIG-IP. You can omit this option if the environment variable `F5_PASSWORD` is set. aliases: pass, pwd
validate_certs	Choices: no yes ←	If `no`, SSL certificates will not be validated. Use this only on personally controlled sites using self-signed certificates. You can omit this option if the environment variable `F5_VALIDATE_CERTS` is set.
transport required	Choices: rest cli ←	Configures the transport connection to use when connecting to the remote device.
quorum (added in 2.2)		Monitor quorum value when `monitor_type` is `m_of_n`.
server required		The BIG-IP host. You can omit this option if the environment variable `F5_SERVER` is set.
server_port (added in 2.2)	Default: 443	The BIG-IP server port. You can omit this option if the environment variable `F5_SERVER_PORT` is set.
state	Choices: present ← absent enabled disabled offline	Specifies the current state of the node. `enabled` (All traffic allowed), specifies that system sends traffic to this node regardless of the node's state. `disabled` (Only persistent or active connections allowed), Specifies that the node can handle only persistent or active connections. `offline` (Only active connections allowed), Specifies that the node can handle only active connections. In all cases except `absent`, the node will be created if it does not yet exist. Be particularly careful about changing the status of a node whose FQDN cannot be resolved. These situations disable your ability to change their `state` to `disabled` or `offline`. They will remain in an Unavailable - Enabled state.
user required		The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You can omit this option if the environment variable `F5_USER` is set.
validate_certs (added in 2.0)	Choices: no yes ←	If `no`, SSL certificates will not be validated. Use this only on personally controlled sites using self-signed certificates. You can omit this option if the environment variable `F5_VALIDATE_CERTS` is set.

Notes ¶

Note

Requires the netaddr Python package on the host. This is as easy as pip install netaddr
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.
