bigip_node – Manages F5 BIG-IP LTM nodes
Synopsis
- Manages F5 BIG-IP LTM nodes.
Parameters
Parameter | Choices/Defaults | Comments | |
---|---|---|---|
address string 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 | ||
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. | ||
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 - |
| 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 added in 2.7 | 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 added in 2.7 | 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 string 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 | ||
fqdn_address_type string added in 2.6 |
| 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. | |
fqdn_auto_populate boolean added in 2.6 |
| 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 node, if this parameter is not specified and fqdn is specified, this parameter will default to yes .This parameter cannot be changed after it has been set. | |
fqdn_down_interval integer added in 2.6 | 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 added in 2.6 | Specifies the interval in 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 akin to specifying 3600 .When creating a new node, if this parameter is not specified and fqdn is specified, this parameter will default to 3600 . | ||
monitor_type string |
| 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 list added in 2.2 | Specifies the health monitors that the system currently uses to monitor this node. | ||
name string / required | Specifies the name of the node. | ||
partition string added in 2.5 | Default: "Common" | Device 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 | ||
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 |
| 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 |
| 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 . | |
quorum integer added in 2.2 | Monitor quorum value when monitor_type is m_of_n . | ||
rate_limit integer added in 2.7 | Node rate limit (connections-per-second). Setting this to 0 disables the limit. | ||
ratio integer added in 2.7 | 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. | ||
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 |
| 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 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 |
| 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.
