Adds the bigip_configsync_actions module (#26506)
This module is required as part of HA configuration of a set of BIG-IPs. It is used to initiate and way for configuration syncing to happen. Unit tests are provided. Integration tests can be found here https://github.com/F5Networks/f5-ansible/blob/devel/test/integration/bigip_configsync_actions.yaml#L23 https://github.com/F5Networks/f5-ansible/tree/devel/test/integration/targets/bigip_configsync_actions/tasks

module: bigip_configsync_actions
|
||||
short_description: Perform different actions related to config-sync.
|
||||
description:
|
||||
- Allows one to run different config-sync actions. These actions allow
|
||||
you to manually sync your configuration across multiple BIG-IPs when
|
||||
those devices are in an HA pair.
|
||||
version_added: "2.4"
|
||||
options:
|
||||
device_group:
|
||||
description:
|
||||
- The device group that you want to perform config-sync actions on.
|
||||
required: True
|
||||
sync_device_to_group:
|
||||
description:
|
||||
- Specifies that the system synchronizes configuration data from this
|
||||
device to other members of the device group. In this case, the device
|
||||
will do a "push" to all the other devices in the group. This option
|
||||
is mutually exclusive with the C(sync_group_to_device) option.
|
||||
choices:
|
||||
- yes
|
||||
- no
|
||||
sync_most_recent_to_device:
|
||||
description:
|
||||
- Specifies that the system synchronizes configuration data from the
|
||||
device with the most recent configuration. In this case, the device
|
||||
will do a "pull" from the most recently updated device. This option
|
||||
is mutually exclusive with the C(sync_device_to_group) options.
|
||||
choices:
|
||||
- yes
|
||||
- no
|
||||
overwrite_config:
|
||||
description:
|
||||
- Indicates that the sync operation overwrites the configuration on
|
||||
the target.
|
||||
default: no
|
||||
choices:
|
||||
- yes
|
||||
- no
|
||||
notes:
|
||||
- Requires the f5-sdk Python package on the host. This is as easy as pip
|
||||
install f5-sdk.
|
||||
- Requires the objectpath Python package on the host. This is as easy as pip
|
||||
install objectpath.
|
||||
requirements:
|
||||
- f5-sdk >= 2.2.3
