Name given to the changeset when creating a changeset. Only used when create_changeset=true. By default a name prefixed with Ansible-STACKNAME is generated based on input parameters.

If stack already exists create a changeset instead of directly applying changes. See the AWS Change Sets docs https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-changesets.html.

Name of the CloudFormation stack. |

The path of the file containing the CloudFormation stack policy. A policy cannot be removed once placed, but it can be modified. for instance, allow all updates https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/protect-stack-resources.html#d0e9051 |

If state=present, stack will be created. If state=present and if stack exists and template has changed, it will be updated. If state=absent, stack will be removed. Choices:
|
|
Dictionary of tags to associate with stack and its resources during stack creation. Can be updated later, updating tags removes previous entries. |
|
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 If state=present and the stack does not exist yet, either template, template_body or template_url must be specified (but only one of them). If state=present, the stack does exist, and neither template, template_body nor template_url are specified, the previous template will be reused. |
|
Template body. Use this to pass in the actual body of the CloudFormation template. If state=present and the stack does not exist yet, either template, template_body or template_url must be specified (but only one of them). If state=present, the stack does exist, and neither template, template_body nor template_url are specified, the previous template will be reused. |
|
A list of hashes of all the template variables for the stack. The value can be a string or a dict. Dict can be used to set additional template parameter attributes like UsePreviousValue (see example). Default: |
|
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=present and the stack does not exist yet, either template, template_body or template_url must be specified (but only one of them). If state=present, the stack does exist, and neither template, template_body nor template_url are specified, the previous template will be reused. |

|
When set to Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead. Choices:

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.
