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

Note

This inventory plugin is part of the community.general collection (version 4.8.1).

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

    Why: Fixes typing error in INI section name

    Alternative: Use the ‘defaults’ section instead

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=dictionary

added in 2.0.0 of community.general

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

Default: []

default_value

string

added in 2.12 of ansible.builtin

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

This option is mutually exclusive with trailing_separator.

key

string

The key from input dictionary used to generate groups

parent_group

string

parent group for keyed group

prefix

string

A keyed group name will start with this prefix

Default: “”

separator

string

separator used to build the keyed group name

Default: “_”

trailing_separator

boolean

added in 2.12 of ansible.builtin

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

This option is mutually exclusive with default_value.

Choices:

  • no

  • yes ← (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:

  • no ← (default)

  • yes

Configuration:

  • INI entry:

    [inventory_plugins]
    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

# You can use Jinja to template the access token.
plugin: community.general.linode
access_token: "{{ lookup('ini', 'token', section='your_username', file='~/.config/linode-cli') }}"
# For older Ansible versions, you need to write this as:
# access_token: "{{ lookup('ini', 'token section=your_username file=~/.config/linode-cli') }}"

# 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"

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
