Synopsis

Launches or updates an AWS CloudFormation stack and waits for it complete.

Requirements (on host that executes module)

boto
botocore>=1.4.57
python >= 2.6

Options

parameter	required	default	choices	comments
aws_access_key	no			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	no			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
changeset_name (added in 2.4)	no			Name given to the changeset when creating a changeset, only used when create_changeset is true. By default a name prefixed with Ansible-STACKNAME is generated based on input parameters. See the AWS Change Sets docs http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-changesets.html
create_changeset (added in 2.4)	no			If stack already exists create a changeset instead of directly applying changes. See the AWS Change Sets docs http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-changesets.html. WARNING: if the stack does not exist, it will be created without changeset. If the state is absent, the stack will be deleted immediately with no changeset.
disable_rollback	no	false	true false	If a stacks fails to form, rollback will remove the stack
ec2_url	no			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.
notification_arns (added in 2.0)	no			The Simple Notification Service (SNS) topic ARNs to publish stack related events.
profile (added in 1.6)	no			Uses a boto profile. Only works with boto >= 2.24.0.
region	no			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
role_arn (added in 2.3)	no			The role that AWS CloudFormation assumes to create the stack. See the AWS CloudFormation Service Role docs http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-servicerole.html
security_token (added in 1.6)	no			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_name	yes			name of the cloudformation stack
stack_policy (added in 1.9)	no			the path of the cloudformation stack policy. A policy cannot be removed once placed, but it can be modified. (for instance, [allow all updates](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/protect-stack-resources.html#d0e9051)
state	yes			If state is "present", stack will be created. If state is "present" and if stack exists and template has changed, it will be updated. If state is "absent", stack will be removed.
tags (added in 1.4)	no			Dictionary of tags to associate with stack and its resources during stack creation. Can be updated later, updating tags removes previous entries.
template	no			The local path of the cloudformation template. This must be the full path to the file, relative to the working directory. If using roles this may look like "roles/cloudformation/files/cloudformation-example.json". If 'state' is 'present' and the stack does not exist yet, either 'template' or 'template_url' must be specified (but not both). If 'state' is present, the stack does exist, and neither 'template' nor 'template_url' are specified, the previous template will be reused.
template_format (added in 2.0)	no	json	json yaml	(deprecated) For local templates, allows specification of json or yaml format. Templates are now passed raw to CloudFormation regardless of format. This parameter is ignored since Ansible 2.3.
template_parameters	no			a list of hashes of all the template variables for the stack
template_url (added in 2.0)	no			Location of file containing the template body. The URL must point to a template (max size 307,200 bytes) located in an S3 bucket in the same region as the stack. If 'state' is 'present' and the stack does not exist yet, either 'template' or 'template_url' must be specified (but not both). If 'state' is present, the stack does exist, and neither 'template' nor 'template_url' are specified, the previous template will be reused.
validate_certs (added in 1.5)	no	yes	yes no	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

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_resources	AWS stack resources and their status. List of dictionaries, one dict per resource.	state == present	list	[{'status': 'UPDATE_COMPLETE', 'physical_resource_id': 'cloudformation2-CFTestSg-16UQ4CYQ57O9F', 'logical_resource_id': 'CFTestSg', 'status_reason': None, 'last_updated_time': '2016-10-11T19:40:14.979000+00:00', 'resource_type': 'AWS::EC2::SecurityGroup'}]
stack_outputs	A key:value dictionary of all the stack outputs currently defined. If there are no stack outputs, it is an empty dictionary.	state == present	dict	{'MySg': 'AnsibleModuleTestYAML-CFTestSg-C8UVS567B6NS'}
events	Most recent events in Cloudformation's event log. This may be from a previous run in some cases.	always	list	['StackEvent AWS::CloudFormation::Stack stackname UPDATE_COMPLETE', 'StackEvent AWS::CloudFormation::Stack stackname UPDATE_COMPLETE_CLEANUP_IN_PROGRESS']
log	Debugging logs. Useful when modifying or finding an error.	always	list	['updating stack']

Notes

Note

As of version 2.3, migrated to boto3 to enable new features. To match existing behavior, YAML parsing is done in the module, not given to AWS as YAML. This will change (in fact, it may change before 2.3 is out).
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

Status
