Synopsis ¶

Gets information about an AWS CloudFormation stack

Requirements ¶

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

boto
boto3 >= 1.0.0
python >= 2.6

Parameters ¶

Parameter	Choices/Defaults	Comments
all_facts	Default: no	Get all stack information for the stack
aws_access_key		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. aliases: ec2_access_key, access_key
aws_secret_key		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. aliases: ec2_secret_key, secret_key
ec2_url		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 (added in 1.6)		Uses a boto profile. Only works with boto >= 2.24.0.
region		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 aliases: aws_region, ec2_region
security_token (added in 1.6)		AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token
stack_events	Default: no	Get stack events for the stack
stack_name		The name or id of the CloudFormation stack. Gathers facts for all stacks by default.
stack_policy	Default: no	Get stack policy for the stack
stack_resources	Default: no	Get stack resources for the stack
stack_template	Default: no	Get stack template body for the stack
validate_certs bool (added in 1.5)	Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

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_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
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

Examples ¶

# Note: These examples do not set authentication details, see the AWS Guide for details.

# Get summary information about a stack
- cloudformation_facts:
    stack_name: my-cloudformation-stack

# Facts are published in ansible_facts['cloudformation'][<stack_name>]
- debug:
    msg: "{{ ansible_facts['cloudformation']['my-cloudformation-stack'] }}"

# Get stack outputs, when you have the stack name available as a fact
- set_fact:
    stack_name: my-awesome-stack

- cloudformation_facts:
    stack_name: "{{ stack_name }}"
  register: my_stack

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

# Get all stack information about a stack
- cloudformation_facts:
    stack_name: my-cloudformation-stack
    all_facts: true

# Get stack resource and stack policy information about a stack
- cloudformation_facts:
    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
  cloudformation_facts:
    stack_name: nonexistent-stack
    all_facts: yes
  failed_when: cloudformation['nonexistent-stack'] is undefined

# Example dictionary outputs for stack_outputs, stack_parameters and stack_resources:
# "stack_outputs": {
#     "ApplicationDatabaseName": "dazvlpr01xj55a.ap-southeast-2.rds.amazonaws.com",
#     ...
# },
# "stack_parameters": {
#     "DatabaseEngine": "mysql",
#     "DatabasePassword": "****",
#     ...
# },
# "stack_resources": {
#     "AutoscalingGroup": "dev-someapp-AutoscalingGroup-1SKEXXBCAN0S7",

#     ...
# }

Return Values ¶

stack_events list	only if all_facts or stack_events is true and the stack exists	All stack events for the stack
stack_outputs dict	if the stack exists	Dictionary of stack outputs keyed by the value of each output 'OutputKey' parameter and corresponding value of each output 'OutputValue' parameter
stack_parameters dict	if the stack exists	Dictionary of stack parameters keyed by the value of each parameter 'ParameterKey' parameter and corresponding value of each parameter 'ParameterValue' parameter
stack_policy dict	only if all_facts or stack_policy is true and the stack exists	Describes the stack policy for the stack
