CloudFormation

Client

class CloudFormation.Client

A low-level client representing AWS CloudFormation:

import boto3

client = boto3.client('cloudformation')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters:operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns:True if the operation can be paginated, False otherwise.
cancel_update_stack(**kwargs)

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.

Note

Only stacks that are in the UPDATE_IN_PROGRESS state can be canceled.

Request Syntax

response = client.cancel_update_stack(
    StackName='string'
)
Parameters:StackName (string) --

[REQUIRED]

The name or the unique stack ID that is associated with the stack.

Returns:None
create_stack(**kwargs)

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.

Request Syntax

response = client.create_stack(
    StackName='string',
    TemplateBody='string',
    TemplateURL='string',
    Parameters=[
        {
            'ParameterKey': 'string',

        },
    ]
)
Parameters:
  • StackName (string) --

    [REQUIRED]

    The name that is associated with the stack. The name must be unique in the region in which you are creating the stack.

    Note

    A stack name can contain only alphanumeric characters (case sensitive) and hyphens. It must start with an alphabetic character and cannot be longer than 255 characters.

  • TemplateBody (string) --

    Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. For more information, go to Template Anatomy in the AWS CloudFormation User Guide.

    Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.

  • TemplateURL (string) --

    Location of file containing the template body. The URL must point to a template (max size: 460,800 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 specify either the TemplateBody or the TemplateURL parameter, but not both.

  • Parameters (list) --

    A list of Parameter structures that specify input parameters for the stack.

    • (dict) --

      The Parameter data type.

      • ParameterKey (string) --

        The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.

      • ParameterValue (string) --

        The value associated with the parameter.

      • UsePreviousValue (boolean) --

        During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.

  • DisableRollback (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

  • TimeoutInMinutes (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.
  • NotificationARNs (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).

    • (string) --
  • Capabilities (list) --

    A list of capabilities that you must specify before AWS CloudFormation can create or update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.

    Currently, the only valid value is CAPABILITY_IAM , which is required for the following resources: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review any permissions associated with them. If you don't specify this parameter, this action returns an InsufficientCapabilities error.

    • (string) --
  • OnFailure (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

  • StackPolicyBody (string) -- Structure containing the stack policy body. For more information, go to Prevent Updates to Stack Resources in the AWS CloudFormation User Guide. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
  • StackPolicyURL (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. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
  • Tags (list) --

    A set of user-defined Tags to associate with this stack, represented by key/value pairs. Tags defined for the stack are propagated to EC2 resources that are created as part of the stack. A maximum number of 10 tags can be specified.

    • (dict) --

      The Tag type is used by CreateStack in the Tags parameter. It allows you to specify a key/value pair that can be used to store information related to cost allocation for an AWS CloudFormation stack.

      • Key (string) --

        Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .

)
Parameters:
  • StackName (string) --

    [REQUIRED]

    The name or unique stack ID that you want to associate a policy with.

signal_resource(**kwargs)

Sends a signal to the specified resource with a success or failure status. You can use the SignalResource API in conjunction with a creation policy or update policy. AWS CloudFormation doesn't proceed with a stack creation or update until resources receive the required number of signals or the timeout period is exceeded. The SignalResource API is useful in cases where you want to send signals from anywhere other than an Amazon EC2 instance.

Request Syntax

response = client.signal_resource(
    StackName='string',
    LogicalResourceId='string',
    UniqueId='string',
    Status='SUCCESS'|'FAILURE'

  • Status (string) --

    [REQUIRED]

    The status of the signal, which is either success or failure. A failure signal causes AWS CloudFormation to immediately fail the stack creation or update.

Returns:

None

update_stack(**kwargs)

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

cancel_update()

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.

Note

Only stacks that are in the UPDATE_IN_PROGRESS state can be canceled.

Request Syntax

response = stack.cancel_update()
Returns:None
delete()

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.

Request Syntax

response = stack.delete()
Returns:None
load()

Calls cloudformation.Client.describe_stacks() to update the attributes of the Stack resource

Request Syntax

stack.load()
Returns:None
reload()

Calls cloudformation.Client.describe_stacks() to update the attributes of the Stack resource

Request Syntax

stack.reload()
Returns:None
update(**kwargs)

Updates a stack as specified in the template. After the call completes successfully, the stack update starts. You can check the status of the stack via the DescribeStacks action.

To get a copy of the template for an existing stack, you can use the GetTemplate action.

Tags that were associated with this stack during creation time will still be associated with the stack after an UpdateStack operation.

For more information about creating an update template, updating a stack, and monitoring the progress of the update, see Updating a Stack .

Request Syntax

response = stack.update(
    TemplateBody='string',
    TemplateURL='string',
    UsePreviousTemplate=True|False,
    StackPolicyDuringUpdateBody='string',
    StackPolicyDuringUpdateURL='string',
    Parameters=[
        {
            'ParameterKey': 'string',
            'ParameterValue': 'string',
            'UsePreviousValue': True|False
        },
    ],
    Capabilities=[
        'CAPABILITY_IAM',
    ],
    StackPolicyBody='string',
    StackPolicyURL='string',
    NotificationARNs=[
        'string',
    ]
)
Parameters:
  • TemplateBody (string) --

    Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. (For more information, go to Template Anatomy in the AWS CloudFormation User Guide.)

    Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.

  • TemplateURL (string) --

    Location of file containing the template body. The URL must point to a template located in an S3 bucket in the same region as the stack. For more information, go to Template Anatomy in the AWS CloudFormation User Guide.

    Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.

  • UsePreviousTemplate (boolean) -- Reuse the existing template that is associated with the stack that you are updating.
  • StackPolicyDuringUpdateBody (string) --

    Structure containing the temporary overriding stack policy body. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.

    If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.

  • StackPolicyDuringUpdateURL (string) --

    Location of a file containing the temporary overriding stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.

    If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.

  • Parameters (list) --

    A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.

    • (dict) --

      The Parameter data type.

      • ParameterKey (string) --

        The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.

      • ParameterValue (string) --

        The value associated with the parameter.

      • UsePreviousValue (boolean) --

        During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.

  • Capabilities (list) --

    A list of capabilities that you must specify before AWS CloudFormation can create or update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter. Currently, the only valid value is CAPABILITY_IAM , which is required for the following resources: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review any permissions associated with them. If you don't specify this parameter, this action returns an InsufficientCapabilities error.

    • (string) --
  • StackPolicyBody (string) --

    Structure containing a new stack policy body. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

    You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.

  • StackPolicyURL (string) --

    Location of a file containing the updated stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

    You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.

  • NotificationARNs (list) --

    Update the ARNs for the Amazon SNS topics that are associated with the stack.

    • (string) --
Return type:

dict

Returns:
