module: bigip_configsync_action
|
|
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.
|
|
type: bool
|
|
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.
|
|
type: bool
|
|
overwrite_config:
|
|
description:
|
|
- Indicates that the sync operation overwrites the configuration on
|
|
the target.
|
|
default: no
|
|
type: bool
|
|
notes:
|
|
- Requires the objectpath Python package on the host. This is as easy as
|
|
C(pip install objectpath).
