cache

boolean

Toggle to enable/disable the caching of the inventory’s source data, requires a cache plugin setup to work.

Choices:

  • no ← (default)

  • yes

Configuration:

  • INI entry:

    [inventory]
cache = no

  • Environment variable: ANSIBLE_INVENTORY_CACHE

cache_connection

string

Cache connection data or path, read cache plugin documentation for specifics.

Configuration:

  • INI entries:

    [defaults]
fact_caching_connection = None

    [inventory]
cache_connection = None

  • Environment variable: ANSIBLE_CACHE_PLUGIN_CONNECTION

  • Environment variable: ANSIBLE_INVENTORY_CACHE_CONNECTION

cache_plugin

string

Cache plugin to use for the inventory’s source data.

Default: “memory”

Configuration:

  • INI entries:

    [defaults]
fact_caching = memory

cache_plugin = memory

  • Environment variable: ANSIBLE_CACHE_PLUGIN

  • Environment variable: ANSIBLE_INVENTORY_CACHE_PLUGIN

cache_prefix

string

Prefix to use for cache plugin files/tables

Default: “ansible_inventory_”

Configuration:

  • INI entries:

    [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

  • Environment variable: ANSIBLE_INVENTORY_CACHE_TIMEOUT

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: {}

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:

  • no ← (default)

  • yes

keyed_groups

list / elements=dictionary

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)

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:

  • no ← (default)

  • yes

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:

  • no

  • yes ← (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

Notes

Note

  • Ansible versions prior to 2.10 should use the fully qualified plugin name ‘amazon.aws.aws_rds’.

Examples

plugin: aws_rds
regions:
  - us-east-1
  - ca-central-1
keyed_groups:
  - key: 'db_parameter_groups|json_query("[].db_parameter_group_name")'
    prefix: rds_parameter_group
  - key: engine
    prefix: rds
  - key: tags
  - key: region

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.
