amazon.aws.autoscaling_group_info module – Gather information about EC2 Auto Scaling Groups (ASGs) in AWS

Note

This module is part of the amazon.aws collection (version 5.2.0).

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 module, see Requirements for details.

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

New in amazon.aws 5.0.0

Synopsis

  • Gather information about EC2 Auto Scaling Groups (ASGs) in AWS.

  • Prior to release 5.0.0 this module was called community.aws.ec2_asg_info. The usage did not change.

  • This module was originally added to community.aws in release 1.0.0.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 3.6

  • boto3 >= 1.18.0

  • botocore >= 1.21.0

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_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variables may also be used in decreasing order of preference.

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.

Support for the EC2_ACCESS_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.

aws_ca_bundle

path

The location of a CA Bundle to use when validating SSL certificates.

The AWS_CA_BUNDLE environment variable may also be used.

aws_config

dictionary

A dictionary to modify the botocore configuration.

Parameters can be found in the AWS documentation https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config.

debug_botocore_endpoint_logs

boolean

Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook.

The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.

Choices:

  • false ← (default)

  • true

endpoint_url

aliases: ec2_url, aws_endpoint_url, s3_url

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 AWS_URL or EC2_URL environment variables may also be used, in decreasing order of preference.

The ec2_url and s3_url aliases have been deprecated and will be removed in a release after 2024-12-01.

Support for the EC2_URL environment variable has been deprecated and will be removed in a release after 2024-12-01.

name

string

The prefix or name of the auto scaling group(s) you are searching for.

Note: This is a regular expression match with implicit ‘^’ (beginning of string). Append ‘$’ for a complete name match.

profile

aliases: aws_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.

region

aliases: aws_region, ec2_region

string

The AWS region to use.

For global services such as IAM, Route53 and CloudFront, region is ignored.

The AWS_REGION or EC2_REGION environment variables may also be used.

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

The ec2_region alias has been deprecated and will be removed in a release after 2024-12-01

Support for the EC2_REGION environment variable has been deprecated and will be removed in a release after 2024-12-01.

secret_key

aliases: aws_secret_access_key, aws_secret_key, ec2_secret_key

string

AWS secret access key.

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_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variables may also be used in decreasing order of preference.

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.

The AWS_SESSION_TOKEN, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variables may also be used in decreasing order of preference.

The security_token and profile options are mutually exclusive.

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.

Support for the EC2_SECRET_KEY and AWS_SECURITY_TOKEN environment variables has been deprecated and will be removed in a release after 2024-12-01.

tags

dictionary

A dictionary/hash of tags in the format { tag1_name: ‘tag1_value’, tag2_name: ‘tag2_value’ } to match against the auto scaling group(s) you are searching for.

validate_certs

boolean

When set to false, SSL certificates will not be validated for communication with the AWS APIs.

Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead.

Choices:

  • false

  • true ← (default)

Notes

Note

  • 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.
