Synopsis

Reads instance inventories from Linode.

Uses a YAML configuration file that ends with linode.(yml|yaml).

Linode labels are used by default as the hostnames.

The default inventory groups are built from groups (deprecated by Linode) and not tags.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 3
  • linode_api4 >= 2.0.0

Parameters

plugin (Required, type=any):

• Marks this as an instance of the 'linode' plugin

• Options: linode, linode.cloud.instance

api_token (Required, type=any):
• The Linode account personal access token.
regions (type=list):
• Populate inventory with instances in this region.
tags (type=list):
• Populate inventory only with instances which have at least one of the tags listed here.
types (type=list):
• Populate inventory with instances with this type.
strict (type=bool):

• If yes make invalid entries a fatal error, otherwise skip and continue.

• Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default.

compose (type=dict):
• Create vars from jinja2 expressions.
groups (type=dict):
• Add hosts to group based on Jinja2 conditionals.
keyed_groups (type=list):

• Add hosts to group based on the values of a variable.

parent_group (type=str):
• parent group for keyed group
prefix (type=str):
• A keyed group name will start with this prefix
separator (type=str, default=_):
• separator used to build the keyed group name
key (type=str):
• The key from input dictionary used to generate groups
default_value (type=str):

• The default value when the host variable's value is an empty string.

• This option is mutually exclusive with keyed_groups[].trailing_separator.

trailing_separator (type=bool, default=True):

• Set this option to False to omit the keyed_groups[].separator after the host variable when the value is an empty string.

• This option is mutually exclusive with keyed_groups[].default_value.

use_extra_vars (type=bool):
• Merge extra vars into the available variables for composition (highest precedence).
leading_separator (type=boolean, default=True):

• Use in conjunction with keyed_groups.

• By default, a keyed group that does not have a prefix or a separator provided will have a name that starts with an underscore.

• This is because the default prefix is "" and the default separator is "_".

• Set this option to False to omit the leading underscore (or other separator) if no prefix is given.

• If the group name is derived from a mapping the separator is still used to concatenate the items.

• To not use a separator in the group name at all, set the separator for the keyed group to an empty string instead.

Examples

# Minimal example. `LINODE_API_TOKEN` is exposed in environment.
plugin: linode.cloud.instance

# Example with regions, types, groups and access token
plugin: linode.cloud.instance
api_token: foobar
regions:
  - eu-west
types:
  - g5-standard-2

# Example with keyed_groups, groups, and compose
plugin: linode.cloud.instance
api_token: foobar
keyed_groups:
  - key: tags
    separator: ''
  - key: region
    prefix: region
groups:
  webservers: "'web' in (tags|list)"
  mailservers: "'mail' in (tags|list)"
compose:
  ansible_port: 2222
