module: vdirect_commit
author: Evgeny Fedoruk @ Radware LTD (@evgenyfedoruk)
short_description: Commits pending configuration changes on Radware devices
description:
- Commits pending configuration changes on one or more Radware devices via vDirect server.
- For Alteon ADC device, apply, sync and save actions will be performed by default.
Skipping of an action is possible by explicit parameter specifying.
- For Alteon VX Container device, no sync operation will be performed
since sync action is only relevant for Alteon ADC devices.
- For DefensePro and AppWall devices, a bulk commit action will be performed.
Explicit apply, sync and save actions specifying is not relevant.
notes:
- Requires the Radware vdirect-client Python package on the host. This is as easy as
C(pip install vdirect-client)

description:
- If C(no), an HTTP connection will be used instead of the default HTTPS connection,
- may be set as C(VDIRECT_HTTPS) or C(VDIRECT_USE_SSL) environment variable.
required: false
type: bool
default: 'yes'
vdirect_validate_certs:
description:
- If C(no), SSL certificates will not be validated,
- may be set as C(VDIRECT_VALIDATE_CERTS) or C(VDIRECT_VERIFY) environment variable.

required: false
type: bool
default: 'yes'
devices:
description:
- List of Radware Alteon device names for commit operations.
required: true
