version_added: "2.4"

author: "Trishna Guha (@trishnaguha)"

short_description: Manage the collection of local users on VyOS device
|
|
description:
|
|
- This module provides declarative management of the local usernames
|
|
configured on network devices. It allows playbooks to manage
|
|
either individual usernames or the collection of usernames in the
|
|
current running config. It also supports purging usernames from the
|
|
configuration that are not explicitly defined.
|
|
notes:
|
|
- Tested against VYOS 1.1.7
|
|
options:
|
|
aggregate:
|
|
description:
|
|
- The set of username objects to be configured on the remote
|
|
VyOS device. The list entries can either be the username or
|
|
a hash of username and properties. This argument is mutually
|
|
exclusive with the C(name) argument.
|
|
aliases: ['users', 'collection']
|
|
name:
|
|
description:
|
|
- The username to be configured on the VyOS device.
|
|
This argument accepts a string value and is mutually exclusive
|
|
with the C(aggregate) argument.
|
|
Please note that this option is not same as C(provider username).
|
|
full_name:
|
|
description:
|
|
- The C(full_name) argument provides the full name of the user
|
|
account to be created on the remote device. This argument accepts
|
|
any text string value.
|
|
configured_password:
|
|
description:
|
|
- The password to be configured on the VyOS device. The
|
|
password needs to be provided in clear and it will be encrypted
|
|
on the device.
|
|
Please note that this option is not same as C(provider password).
|
|
update_password:
|
|
description:
|
|
- Since passwords are encrypted in the device running config, this
|
|
argument will instruct the module when to change the password. When
|
|
set to C(always), the password will always be updated in the device
|
|
and when set to C(on_create) the password will be updated only if
|
|
the username is created.
|
|
default: always
|
|
choices: ['on_create', 'always']
|
|
level:
|
|
description:
|
|
- The C(level) argument configures the level of the user when logged
|
|
into the system. This argument accepts string values admin or operator.
|
|
aliases: ['role']
|
|
purge:
|
|
description:
|
|
- Instructs the module to consider the
|
|
resource definition absolute. It will remove any previously
|
|
configured usernames on the device with the exception of the
|
|
`admin` user (the current defined set of users).

- Configures the state of the username definition

as it relates to the device operational configuration. When set

to I(present), the username(s) should be configured in the device active
