amazon.aws.aws_rds inventory – RDS instance inventory source

Note

This inventory plugin is part of the amazon.aws collection (version 9.0.0).

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 amazon.aws. You need further requirements to be able to use this inventory plugin, see Requirements for details.

To use it in a playbook, specify: amazon.aws.aws_rds.

Synopsis

  • Get instances and clusters from Amazon Web Services RDS.

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

Requirements

The below requirements are needed on the local controller node that executes this inventory.

  • python >= 3.6

  • boto3 >= 1.28.0

  • botocore >= 1.31.0

Parameters

Parameter

Comments

access_key

aliases: aws_access_key_id, aws_access_key, ec2_access_key

string

AWS access key ID.

See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys.

The aws_access_key and profile options are mutually exclusive.

The aws_access_key_id alias was added in release 5.1.0 for consistency with the AWS botocore SDK.

The ec2_access_key alias has been deprecated and will be removed in a release after 2024-12-01.

Configuration:

  • Environment variable: AWS_ACCESS_KEY_ID

  • Environment variable: AWS_ACCESS_KEY

  • Environment variable: EC2_ACCESS_KEY

    Removed in: major release after 2024-12-01

    Why: EC2 in the name implied it was limited to EC2 resources. However, it is used for all connections.

    Alternative: AWS_ACCESS_KEY_ID

assume_role_arn

aliases: iam_role_arn

string

The ARN of the IAM role to assume to perform the lookup.

You should still provide AWS credentials with enough privilege to perform the AssumeRole action.

cache

boolean

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

Choices:

  • false ← (default)

  • true

Configuration:

cache_connection

string

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

Configuration:

cache_plugin

string

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

Default: "memory"

Configuration:

cache_prefix

string

Prefix to use for cache plugin files/tables.

Default: "ansible_inventory_"

Configuration:

cache_timeout

Default: 3600

Configuration:

compose

dictionary

Create vars from jinja2 expressions.

Default: {}

endpoint_url

aliases: aws_endpoint_url, endpoint

string

URL to connect to instead of the default AWS endpoints. While this can be used to connection to other AWS-compatible services the amazon.aws and community.aws collections are only tested against AWS.

The endpoint alias has been deprecated and will be removed in a release after 2024-12-01.

Configuration:

  • Environment variable: AWS_URL

  • Environment variable: EC2_URL

    Removed in: major release after 2024-12-01

    Why: EC2 in the name implied it was limited to EC2 resources. However, it is used for all connections.

    Alternative: AWS_URL

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.

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 keyed_groups[].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 keyed_groups[].separator after the host variable when the value is an empty string.

This option is mutually exclusive with keyed_groups[].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)

profile

aliases: aws_profile, boto_profile

string

A named AWS profile to use for authentication.

See the AWS documentation for more information about named profiles https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html.

The profile option is mutually exclusive with the aws_access_key, aws_secret_key and security_token options.

The boto_profile alias has been deprecated and will be removed in a release after 2024-12-01.

Configuration:

region

aliases: aws_region, ec2_region

string

The AWS region to use.

See the Amazon AWS documentation for more information http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region.

Configuration:

  • Environment variable: AWS_REGION

  • Environment variable: EC2_REGION

    Removed in: major release after 2024-12-01

    Why: EC2 in the name implied it was limited to EC2 resources, when it is used for all connections

    Alternative: AWS_REGION

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: []

secret_key

The secret_key and profile options are mutually exclusive.

The aws_secret_access_key alias was added in release 5.1.0 for consistency with the AWS botocore SDK.

Aliases aws_session_token and session_token were added in release 3.2.0, with the parameter being renamed from security_token to session_token in release 6.0.0.

The security_token, aws_security_token, and access_token aliases have been deprecated and will be removed in a release after 2024-12-01.

Configuration:

  • Environment variable: AWS_SESSION_TOKEN

  • Environment variable: AWS_SECURITY_TOKEN

    Removed in: major release after 2024-12-01

    Why: AWS_SECURITY_TOKEN was used for compatibility with the original boto SDK, support for which has been dropped

    Alternative: AWS_SESSION_TOKEN

  • Environment variable: EC2_SECURITY_TOKEN

    Removed in: major release after 2024-12-01

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

Notes

Note

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

  • Caution: For modules, environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. As such, files may need to be explicitly copied to the ‘host’. For lookup and connection plugins, environment variables and configuration files are read from the Ansible ‘controller’ context and not the ‘host’ context.

  • The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.

  - us-east-1
  - ca-central-1

    prefix: rds_parameter_group
  - key: engine

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.
