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 >= 3.0.9
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 can omit this option if the environment variable F5_PASSWORD is set.aliases: pass, pwd | ||
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. 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 |
| 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 |
| Configures the transport connection to use when connecting to the remote device. | |
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 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. | |
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 can omit this option if the environment variable F5_USER is set. | ||
validate_certs (added in 2.0) |
| 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 BIG-IP software version >= 12.
- 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
.
