community.general.linode – Ansible dynamic inventory plugin for Linode.

Note

This plugin is part of the community.general collection (version 3.8.3).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.linode.

Synopsis

  • Reads inventories from the Linode API v4.

  • 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 local controller node that executes this inventory.

  • python >= 2.7

  • linode_api4 >= 2.0.0

Parameters

Parameter

Comments

access_token

string / required

The Linode account personal access token.

Configuration:

  • Environment variable: LINODE_ACCESS_TOKEN

compose

dictionary

added in 2.0.0 of community.general

Create vars from jinja2 expressions.

Default: {}

groups

dictionary

added in 2.0.0 of community.general

Add hosts to group based on Jinja2 conditionals.

Default: {}

ip_style

string

added in 3.6.0 of community.general

Populate hostvars with all information available from the Linode APIv4.

Choices:

  • plain ← (default)

  • api

keyed_groups

list / elements=string

added in 2.0.0 of community.general

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

Default: []

leading_separator

boolean

added in 2.11 of ansible.builtin

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.

Choices:

  • no

  • yes ← (default)

plugin

string / required

Marks this as an instance of the ‘linode’ plugin.

Choices:

  • linode

  • community.general.linode

regions

list / elements=string

Populate inventory with instances in this region.

Default: []

strict

boolean

added in 2.0.0 of community.general

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.

Choices:

  • no ← (default)

  • yes

tags

list / elements=string

added in 2.0.0 of community.general

Populate inventory only with instances which have at least one of the tags listed here.

Default: []

types

list / elements=string

Populate inventory with instances with this type.

Default: []

use_extra_vars

boolean

added in 2.11 of ansible.builtin

Merge extra vars into the available variables for composition (highest precedence).

Choices:

use_extra_vars = no

  • Environment variable: ANSIBLE_INVENTORY_USE_EXTRA_VARS

Examples

# Minimal example. `LINODE_ACCESS_TOKEN` is exposed in environment.
plugin: community.general.linode

# Example with regions, types, groups and access token
plugin: community.general.linode
access_token: foobar
regions:
  - eu-west
types:
  - g5-standard-2

# Example with keyed_groups, groups, and compose
plugin: community.general.linode
access_token: foobar
keyed_groups:
  - key: tags
    separator: ''
  - key: region
    prefix: region
groups:
  webservers: "'web' in (tags|list)"
  mailservers: "'mail' in (tags|list)"
compose:
  # By default, Ansible tries to connect to the label of the instance.
  # Since that might not be a valid name to connect to, you can
  # replace it with the first IPv4 address of the linode as follows:
  ansible_ssh_host: ipv4[0]
  ansible_port: 2222

# Example where control traffic limited to internal network
plugin: community.general.linode
access_token: foobar
ip_style: api
compose:
  ansible_host: "ipv4 | community.general.json_query('[?public==`false`].address') | first"
