bigip_device_group - Manage device groups on a BIG-IP

New in version 2.5.

Synopsis

  • Managing device groups allows you to create HA pairs and clusters of BIG-IP devices. Usage of this module should be done in conjunction with the bigip_configsync_actions to sync configuration across the pair or cluster if auto-sync is disabled.

Requirements

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

  • f5-sdk >= 3.0.9

Parameters

Parameter
Choices/Defaults
Comments
auto_sync
    Choices:
  • no
  • yes
Indicates whether configuration synchronization occurs manually or automatically. When creating a new device group, this option will default to false.
description
Description of the device group.
full_sync
    Choices:
  • no
  • yes
Specifies whether the system synchronizes the entire configuration during synchronization operations. When false, the system performs incremental synchronization operations, based on the cache size specified in max_incremental_sync_size. Incremental configuration synchronization is a mechanism for synchronizing a device-group's configuration among its members, without requiring a full configuration load for each configuration change. In order for this to work, all devices in the device-group must initially agree on the configuration. Typically this requires at least one full configuration load to each device. When creating a new device group, this option will default to false.
max_incremental_sync_size
Specifies the size of the changes cache for incremental sync. For example, using the default, if you make more than 1024 KB worth of incremental changes, the system performs a full synchronization operation. Using incremental synchronization operations can reduce the per-device sync/load time for configuration changes. This setting is relevant only when full_sync is false.
name
required
Specifies the name of the device group.
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.
save_on_auto_sync
    Choices:
  • no
  • yes
When performing an auto-sync, specifies whether the configuration will be saved or not. If false, only the running configuration will be changed on the device(s) being synced to. When creating a new device group, this option will default to false.
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
When state is present, ensures the device group exists.
When state is absent, ensures that the device group is removed.
type
    Choices:
  • sync-failover
  • sync-only
Specifies that the type of group. A sync-failover device group contains devices that synchronize their configuration data and fail over to one another when a device becomes unavailable. A sync-only device group has no such failover. When creating a new device group, this option will default to sync-only. This setting cannot be changed once it has been 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.
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

  • This module is primarily used as a component of configuring HA pairs of BIG-IP devices.
  • Requires BIG-IP >= 12.1.x.
  • 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.

Examples

- name: Create a sync-only device group
  bigip_device_group:
    name: foo-group
    password: secret
    server: lb.mydomain.com
    state: present
    user: admin
  delegate_to: localhost

- name: Create a sync-only device group with auto-sync enabled
  bigip_device_group:
    name: foo-group
    auto_sync: yes
    password: secret
    server: lb.mydomain.com
    state: present
    user: admin
  delegate_to: localhost
