amazon.aws.cloudformation_info – Obtain information about an AWS CloudFormation stack

Note

This plugin is part of the amazon.aws collection (version 1.5.1).

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 amazon.aws.

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

New in version 1.0.0: of amazon.aws

Synopsis

  • Gets information about an AWS CloudFormation stack.

  • This module was called amazon.aws.cloudformation_facts before Ansible 2.9, returning ansible_facts. Note that the amazon.aws.cloudformation_info module no longer returns ansible_facts!

Requirements

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

  • boto

  • boto3 >= 1.0.0

  • python >= 2.6

Parameters

Parameter

Comments

all_facts

boolean

Get all stack information for the stack.

Choices:

  • no ← (default)

  • yes

aws_access_key

aliases: ec2_access_key, access_key

string

AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used.

If profile is set this parameter is ignored.

Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aws_ca_bundle

path

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

Only used for boto3 based modules.

Note: The CA Bundle is read ‘module’ side and may need to be explicitly copied from the controller if not run locally.

aws_config

dictionary

A dictionary to modify the botocore configuration.

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

Only the ‘user_agent’ key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration.

aws_secret_key

aliases: ec2_secret_key, secret_key

string

AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used.

If profile is set this parameter is ignored.

Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

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:

  • no ← (default)

  • yes

ec2_url

aliases: aws_endpoint_url, endpoint_url

string

Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.

profile

aliases: aws_profile

string

Uses a boto profile. Only works with boto >= 2.24.0.

Using profile will override aws_access_key, aws_secret_key and security_token and support for passing them at the same time as profile has been deprecated.

aws_access_key, aws_secret_key and security_token will be made mutually exclusive with profile after 2022-06-01.

region

aliases: aws_region, ec2_region

string

The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region

security_token

aliases: aws_security_token, access_token

string

AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used.

If profile is set this parameter is ignored.

Passing the security_token and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

stack_change_sets

boolean

Get stack change sets for the stack

Choices:

  • no ← (default)

  • yes

stack_events

boolean

Get stack events for the stack.

Choices:

  • no ← (default)

  • yes

stack_name

string

The name or id of the CloudFormation stack. Gathers information on all stacks by default.

stack_policy

boolean

Get stack policy for the stack.

Choices:

  • no ← (default)

  • yes

stack_resources

boolean

Get stack resources for the stack.

Choices:

  • no ← (default)

  • yes

stack_template

boolean

Get stack template body for the stack.

Choices:

  • no ← (default)

  • yes

validate_certs

boolean

When set to “no”, SSL certificates will not be validated for boto versions >= 2.6.0.

Choices:

  • no

  • yes ← (default)

Notes

Note

  • If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_PROFILE or AWS_DEFAULT_PROFILE, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN, AWS_REGION or EC2_REGION, AWS_CA_BUNDLE

  • Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html

  • AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file

- debug:
    msg: "{{ my_stack.cloudformation[stack_name].stack_outputs }}"

# Get all stack information about a stack
- amazon.aws.cloudformation_info:
    stack_name: my-cloudformation-stack
    all_facts: true

# Get stack resource and stack policy information about a stack
- amazon.aws.cloudformation_info:
    stack_name: my-cloudformation-stack
    stack_resources: true
    stack_policy: true

# Fail if the stack doesn't exist
- name: try to get facts about a stack but fail if it doesn't exist
  amazon.aws.cloudformation_info:
    stack_name: nonexistent-stack
    all_facts: yes
  failed_when: cloudformation['nonexistent-stack'] is undefined
