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 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

# 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",
#     "AutoscalingSecurityGroup": "sg-abcd1234",
#     "ApplicationDatabase": "dazvlpr01xj55a",
#     "EcsTaskDefinition": "arn:aws:ecs:ap-southeast-2:123456789:task-definition/dev-someapp-EcsTaskDefinition-1F2VM9QB0I7K9:1"
#     ...
# }

Return Values

Common return values are documented here Return Values, the following are the fields unique to this module:

name description returned type sample
stack_description
Summary facts about the stack
 always dict
stack_template
Describes the stack template for the stack
 only if all_facts or stack_template is true dict
stack_policy
Describes the stack policy for the stack
 only if all_facts or stack_policy is true dict
stack_outputs
Dictionary of stack outputs keyed by the value of each output 'OutputKey' parameter and corresponding value of each output 'OutputValue' parameter
 always dict
stack_events
All stack events for the stack
 only if all_facts or stack_events is true list
stack_parameters
Dictionary of stack parameters keyed by the value of each parameter 'ParameterKey' parameter and corresponding value of each parameter 'ParameterValue' parameter
 always dict
stack_resources
Dictionary of stack resources keyed by the value of each resource 'LogicalResourceId' parameter and corresponding value of each resource 'PhysicalResourceId' parameter
 only if all_facts or stack_resourses is true dict
stack_resource_list
Describes stack resources for the stack
 only if all_facts or stack_resourses is true list

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 http://boto.readthedocs.org/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
