Note

You are viewing the documentation for an older version of boto (boto2).

Boto3, the next version of Boto, is now stable and recommended for general use. It can be used side-by-side with Boto in the same project, so it is easy to start using Boto3 in your existing projects as well as new projects. Going forward, API updates and all new feature work will be focused on Boto3.

For more information, see the documentation for boto3.

boto.cloudformation.connection

class boto.cloudformation.connection.CloudFormationConnection(aws_access_key_id=None, aws_secret_access_key=None, is_secure=True, port=None, proxy=None, proxy_port=None, proxy_user=None, proxy_pass=None, debug=0, https_connection_factory=None, region=None, path='/', converter=None, security_token=None, validate_certs=True, profile_name=None)

AWS CloudFormation AWS CloudFormation enables you to create and manage AWS infrastructure deployments predictably and repeatedly. AWS CloudFormation helps you leverage AWS products such as Amazon EC2, EBS, Amazon SNS, ELB, and Auto Scaling to build highly-reliable, highly scalable, cost effective applications without worrying about creating and configuring the underlying AWS infrastructure.

With AWS CloudFormation, you declare all of your resources and dependencies in a template file. The template defines a collection of resources as a single unit called a stack. AWS CloudFormation creates and deletes all member resources of the stack together and manages all dependencies between the resources for you.

For more information about this product, go to the `CloudFormation Product Page`_.

Amazon CloudFormation makes use of other AWS products. If you need additional technical information about a specific AWS product, you can find the product’s technical documentation at `http://aws.amazon.com/documentation/`_.

DefaultRegionName = 'us-east-1'
cancel_update_stack(stack_name_or_id=None)

Cancels an update on the specified stack. If the call completes successfully, the stack will roll back the update and revert to the previous stack configuration. Only stacks that are in the UPDATE_IN_PROGRESS state can be canceled.

Parameters:stack_name_or_id (string) – The name or the unique identifier associated with the stack.
create_stack(stack_name, template_body=None, template_url=None, parameters=None, notification_arns=None, disable_rollback=None, timeout_in_minutes=None, capabilities=None, tags=None, on_failure=None, stack_policy_body=None, stack_policy_url=None)

Creates a stack as specified in the template. After the call completes successfully, the stack creation starts. You can check the status of the stack via the DescribeStacks API. Currently, the limit for stacks is 20 stacks per account per region.

Parameters:stack_name (string) –
The name associated with the stack. The name must be unique within your
AWS account.
Must contain only alphanumeric characters (case sensitive) and start
with an alpha character. Maximum length of the name is 255 characters.
Parameters:template_body (string) – Structure containing the template body. (For more information, go to `Template Anatomy`_ in the AWS CloudFormation User Guide.)
Conditional: You must pass TemplateBody or TemplateURL. If both are
passed, only TemplateBody is used.
Parameters: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. For more information, go to the `Template Anatomy`_ in the AWS CloudFormation User Guide.
Conditional: You must pass TemplateURL or TemplateBody. If both are
passed, only TemplateBody is used.
Parameters:
  • parameters (list) – A list of key/value tuples that specify input parameters for the stack.
  • disable_rollback (boolean) – Set to True to disable rollback of the stack if stack creation failed. You can specify either DisableRollback or OnFailure, but not both.

Default: False

Parameters:
  • timeout_in_minutes (integer) – The amount of time that can pass before the stack status becomes CREATE_FAILED; if DisableRollback is not set or is set to False, the stack will be rolled back.
  • notification_arns (list) – The Simple Notification Service (SNS) topic ARNs to publish stack related events. You can find your SNS topic ARNs using the `SNS console`_ or your Command Line Interface (CLI).
  • capabilities (list) – The list of capabilities that you want to allow in the stack. If your template contains certain resources, you must specify the CAPABILITY_IAM value for this parameter; otherwise, this action returns an InsufficientCapabilities error. The following resources require you to specify the capabilities parameter: `AWS::CloudFormation::Stack`_, `AWS::IAM::AccessKey`_, `AWS::IAM::Group`_, `AWS::IAM::InstanceProfile`_, `AWS::IAM::Policy`_, `AWS::IAM::Role`_, `AWS::IAM::User`_, and `AWS::IAM::UserToGroupAddition`_.
  • on_failure (string) – Determines what action will be taken if stack creation fails. This must be one of: DO_NOTHING, ROLLBACK, or DELETE. You can specify either OnFailure or DisableRollback, but not both.

Default: ROLLBACK

Parameters:stack_policy_body (string) – Structure containing the stack policy body. (For more information, go to ` Prevent Updates to Stack Resources`_ in the AWS CloudFormation User Guide.)
If you pass StackPolicyBody and StackPolicyURL, only
StackPolicyBody is used.
Parameters:
  • stack_policy_url (string) – Location of a file containing the stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. If you pass StackPolicyBody and StackPolicyURL, only StackPolicyBody is used.

delete_stack(stack_name_or_id)

Deletes a specified stack. Once the call completes successfully, stack deletion starts. Deleted stacks do not show up in the DescribeStacks API if the deletion has been completed successfully.

Parameters:stack_name_or_id (string) – The name or the unique identifier associated with the stack.
describe_stack_events(stack_name_or_id=None, next_token=None)

Returns all stack related events for a specified stack. For more information about a stack’s event history, go to `Stacks`_ in the AWS CloudFormation User Guide. Events are returned, even if the stack never existed or has been successfully deleted.

Parameters:stack_name_or_id (string) – The name or the unique identifier associated with the stack.

Default: There is no default value.

Parameters:next_token (string) – String that identifies the start of the next list of events, if there is one.

Default: There is no default value.

describe_stack_resource(stack_name_or_id, logical_resource_id)

If PhysicalResourceId is specified, the associated resources of the stack that the resource belongs to are returned. Only the first 100 resources will be returned. If your stack has more resources than this, you should use ListStackResources instead. For deleted stacks, DescribeStackResources returns resource information for up to 90 days after the stack has been deleted.

You must specify either StackName or PhysicalResourceId, but not both. In addition, you can specify LogicalResourceId to filter the returned result. For more information about resources, the LogicalResourceId and PhysicalResourceId, go to the `AWS CloudFormation User Guide`_. A ValidationError is returned if you specify both StackName and PhysicalResourceId in the same request.

Required: Conditional. If you do not specify PhysicalResourceId, you
must specify StackName.
