bigip_pool – Manages F5 BIG-IP LTM pools
Synopsis
- Manages F5 BIG-IP LTM pools via iControl REST API.
Requirements
The below requirements are needed on the host that executes this module.
- f5-sdk >= 3.0.16
Parameters
Parameter | Choices/Defaults | Comments | |
---|---|---|---|
description - added in 2.3 | Specifies descriptive text that identifies the pool. | ||
lb_method - added in 1.3 |
| Load balancing method. When creating a new pool, if this value is not specified, the default of round-robin will be used. | |
metadata - added in 2.5 | Arbitrary key/value pairs that you can attach to a pool. This is useful in situations where you might want to annotate a pool to me managed by Ansible. Key names will be stored as strings; this includes names that are numbers. Values for all of the keys will be stored as strings; this includes values that are numbers. Data will be persisted, not ephemeral. | ||
monitor_type - added in 1.3 |
| 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. When single ensures that all specified monitors are checked, but additionally includes checks to make sure you only specified a single monitor.When and_list ensures that all monitors are checked.When m_of_n ensures that quorum of monitors are checked. m_of_n requires that a quorum of 1 or greater be set either in the playbook, or already existing on the device.Both single and and_list are functionally identical since BIG-IP considers all monitors as "a list". | |
monitors - added in 1.3 | Monitor template name list. If the partition is not provided as part of the monitor name, then the partition option will be used instead. | ||
name - / required | Pool name aliases: pool | ||
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 may omit this option by setting the environment variable F5_PASSWORD .aliases: pass, pwd | ||
priority_group_activation - added in 2.6 | Specifies whether the system load balances traffic according to the priority number assigned to the pool member. When creating a new pool, if this parameter is not specified, the default of 0 will be used.To disable this setting, provide the value 0 .Once you enable this setting, you can specify pool member priority when you create a new pool or on a pool member's properties screen. The system treats same-priority pool members as a group. To enable priority group activation, provide a number from 0 to 65535 that represents the minimum number of members that must be available in one priority group before the system directs traffic to members in a lower priority group.When a sufficient number of members become available in the higher priority group, the system again directs traffic to the higher priority group. aliases: minimum_active_members | ||
provider - added in 2.5 | Default: null | A dict object containing connection details. | |
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 | ||
server - / required | The BIG-IP host. You may omit this option by setting the environment variable F5_SERVER . | ||
server_port - | Default: 443 | The BIG-IP server port. You may omit this option by setting the environment variable F5_SERVER_PORT . | |
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. | |
transport - / required |
| Configures the transport connection to use when connecting to the remote device. | |
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 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 - added in 1.3 | Monitor quorum value when monitor_type is m_of_n .Quorum must be a value of 1 or greater when monitor_type is m_of_n . | ||
reselect_tries - added in 2.2 | Sets the number of times the system tries to contact a pool member after a passive failure. | ||
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 . | |
service_down_action - added in 1.3 |
| Sets the action to take when node goes down in pool. | |
slow_ramp_time - added in 1.3 | Sets the ramp-up time (in seconds) to gradually ramp up the load on newly added or freshly detected up pool members. | ||
state - added in 2.5 |
| When present , guarantees that the pool exists with the provided attributes.When absent , removes the pool from the system. | |
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 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
- To add members do a pool, use the
bigip_pool_member
module. Previously, thebigip_pool
module allowed the management of users, but this has been removed in version 2.5 of Ansible. - 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.
