f5networks.f5_modules.bigip_node module – Manages F5 BIG-IP LTM nodes

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_node.

New in f5networks.f5_modules 1.0.0

Synopsis

• Manages F5 BIG-IP LTM nodes.

Parameters

Parameter	Comments
address aliases: ip, host string	IP address of the node. This can be either IPv4 or IPv6. When creating a new node, you must provide one of either address or fqdn. This parameter cannot be updated after it is set.
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.
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	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. Choices: "all" "at_least"
connection_limit integer	Node connection limit. Setting this to 0 disables the limit.
description string	Specifies descriptive text that identifies the node. You can remove a description by either specifying an empty string, or by specifying the special value none.
dynamic_ratio integer	The dynamic ratio number for the node. Used for dynamic ratio load balancing. When creating a new node, if this parameter is not specified, the default of 1 will be used.
fqdn aliases: hostname string	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 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 node, you must provide one of either address or fqdn provided. This parameter cannot be updated after it is set.
fqdn_address_type string	Specifies whether the FQDN of the node resolves to an IPv4 or IPv6 address. When creating a new node, if this parameter is not specified and fqdn is specified, this parameter will default to ipv4. This parameter cannot be changed after it has been set. Choices: "ipv4" "ipv6" "all"
fqdn_auto_populate boolean	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 true, 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 false, 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 node, if this parameter is not specified and fqdn is specified, this parameter defaults to true. This parameter cannot be changed after it has been set. Choices: false true
fqdn_down_interval integer	Specifies the interval in which a query occurs, when the DNS server is down. The associated monitor continues polling as long as the DNS server is down. When creating a new node, if this parameter is not specified and fqdn is specified, this parameter will default to 5.
fqdn_up_interval string	Specifies the interval at which a query occurs, when the DNS server is up. The associated monitor attempts to probe three times, and marks the server down if it there is no response within the span of three times the interval value, in seconds. This parameter accepts a value of ttl to query, based off of the TTL of the FQDN. The default TTL interval is similar to specifying 3600. When creating a new node, if this parameter is not specified and fqdn is specified, this parameter will default to 3600.
monitors list / elements=string	Specifies the health monitors the system currently uses to monitor this node.
name string / required	Specifies the name of the node.
partition string	Device partition to manage resources on. Default: "Common"
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)
rate_limit integer	Node rate limit (connections-per-second). Setting this to 0 disables the limit.
ratio integer	Node ratio weight. Valid values range from 1 through 100. When creating a new node, if this parameter is not specified, the default of 1 will be used.
state string	Specifies the current state of the node. enabled (All traffic allowed), specifies the system sends traffic to this node regardless of the node’s state. disabled (Only persistent or active connections allowed), specifies the node can handle only persistent or active connections. offline (Only active connections allowed), specifies 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. Choices: "present" ← (default) "absent" "enabled" "disabled" "offline"

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.
