    [default]
fact_caching_prefix = ansible_inventory_

    Removed in: version 2.16 of ansible.builtin

    Why: Fixes typing error in INI section name

    Alternative: Use the ‘defaults’ section instead

    [defaults]
fact_caching_prefix = ansible_inventory_

    [inventory]
cache_prefix = ansible_inventory_

  • Environment variable: ANSIBLE_CACHE_PLUGIN_PREFIX

  • Environment variable: ANSIBLE_INVENTORY_CACHE_PLUGIN_PREFIX

cache_timeout

integer

Cache duration in seconds

Default: 3600

Configuration:

compose

dictionary

Create vars from jinja2 expressions.

Default: {}

filters

string

A dictionary of filter value pairs. Available filters are listed here https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-instances.html#options. If you filter by db-cluster-id and include_clusters is True it will apply to clusters as well.

Default: {}

groups

dictionary

Add hosts to group based on Jinja2 conditionals.

Default: {}

hostvars_prefix

string

added in amazon.aws 3.1.0

The prefix for host variables names coming from AWS.

hostvars_suffix

string

added in amazon.aws 3.1.0

The suffix for host variables names coming from AWS.

iam_role_arn

string

The ARN of the IAM role to assume to perform the inventory lookup. You should still provide AWS credentials with enough privilege to perform the AssumeRole action.

include_clusters

boolean

Whether or not to query for Aurora clusters as well as instances.

Choices:

  • false ← (default)

  • true

keyed_groups

list / elements=dictionary

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

Default: []

default_value

string

added in ansible-core 2.12

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 ansible-core 2.12

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:

  • false

  • true ← (default)

leading_separator

boolean

added in ansible-core 2.11

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:

  • false

  • true ← (default)

regions

string

A list of regions in which to describe RDS instances and clusters. Available regions are listed here https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.RegionsAndAvailabilityZones.html.

Default: []

statuses

list / elements=string

A list of desired states for instances/clusters to be added to inventory. Set to [‘all’] as a shorthand to find everything.

Default: ["creating", "available"]

strict

boolean

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:

  • false ← (default)

  • true

strict_permissions

boolean

By default if an AccessDenied exception is encountered this plugin will fail. You can set strict_permissions to False in the inventory config file which will allow the restrictions to be gracefully skipped.

Choices:

  • false

  • true ← (default)

use_extra_vars

boolean

added in ansible-core 2.11

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

Choices:

  • false ← (default)

  • true

Configuration:

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.
