stack_name

string / required

Name of the CloudFormation stack.

stack_policy

string

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

stack_policy_body

json

added in amazon.aws 1.5.0

The CloudFormation stack policy in JSON. 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

stack_policy_on_update_body

json

added in amazon.aws 1.5.0

the body of the cloudformation stack policy only applied during this update.

state

string

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:

  • "present" ← (default)

  • "absent"

tags

dictionary

Dictionary of tags to associate with stack and its resources during stack creation.

Can be updated later, updating tags removes previous entries.

template

path

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=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

string

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.

template_parameters

dictionary

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: {}

template_url

string

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.

termination_protection

boolean

Enable or disable termination protection on the stack.

Choices:

  • false

  • true

validate_certs

boolean

When set to false, SSL certificates will not be validated for communication with the AWS APIs.

Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead.

Choices:

  • false

  • true ← (default)

Notes

Note

  • Caution: Environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. Files may need to be explicitly copied to the ‘host’.

  • 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.
