module: linode_v4
short_description: Manage instances on the Linode cloud.
description: Manage instances on the Linode cloud.
requirements:
- python >= 2.7
- linode_api4 >= 2.0.0
author:
- Luke Murphy (@decentral1se)
notes:
- No Linode resizing is currently implemented. This module will, in time,
replace the current Linode module which uses deprecated API bindings on the
Linode side.
options:
region:
description:
- The region of the instance. This is a required parameter only when
creating Linode instances. See
U(https://developers.linode.com/api/v4#tag/Regions).
required: false
type: str
image:
description:
- The image of the instance. This is a required parameter only when
creating Linode instances. See
U(https://developers.linode.com/api/v4#tag/Images).
type: str
required: false
type:
description:
- The type of the instance. This is a required parameter only when
creating Linode instances. See
U(https://developers.linode.com/api/v4#tag/Linode-Types).
type: str
required: false
label:
description:
- The instance label. This label is used as the main determiner for
idempotence for the module and is therefore mandatory.
type: str
required: true
group:
description:
- The group that the instance should be marked under. Please note, that
group labelling is deprecated but still supported. The encouraged
method for marking instances is to use tags.
type: str
required: false
tags:
description:
- The tags that the instance should be marked under. See
U(https://developers.linode.com/api/v4#tag/Tags).
required: false
type: list
root_pass:
description:
- The password for the root user. If not specified, one will be
generated. This generated password will be available in the task
success JSON.
required: false
type: str
authorized_keys:
description:
- A list of SSH public key parts to deploy for the root user.
required: false
type: list
state:
description:
- The desired instance state.
type: str
choices:
- present
- absent
required: true
access_token:
description:
- The Linode API v4 access token. It may also be specified by exposing
the C(LINODE_ACCESS_TOKEN) environment variable. See
U(https://developers.linode.com/api/v4#section/Access-and-Authentication).
required: true
