UpdateStackInput

Type: []*string

In some cases, you must explicity acknowledge that your stack template contains certain capabilities in order for AWS CloudFormation to update the stack.

Some stack templates might include resources that can affect permissions

   in your AWS account; for example, by creating new AWS Identity and Access
    Management (IAM) users. For those stacks, you must explicitly acknowledge
    this by specifying one of these capabilities.
 
 

The following IAM resources require you to specify either the CAPABILITY_IAM

   or CAPABILITY_NAMED_IAM capability.
 
 

If you have IAM resources, you can specify either capability.

If you have IAM resources with custom names, you must specify CAPABILITY_NAMED_IAM.

If you don't specify either of these capabilities, AWS CloudFormation returns

   an InsufficientCapabilities error.
 
 

If your stack template contains these resources, we recommend that you review

   all permissions associated with them and edit their permissions if necessary.

   Templates (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html#capabilities).
 
 

Some template contain macros. Macros perform custom processing on templates;

   this can include simple actions like find-and-replace operations, all
    the way to extensive transformations of entire templates. Because of this,
    users typically create a change set from the processed template, so that
    they can review the changes resulting from the macros before actually
    updating the stack. If your stack template contains one or more macros,
    and you choose to update a stack directly from the processed template,
    without first reviewing the resulting changes in a change set, you must
    acknowledge this capability. This includes the AWS::Include (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/create-reusable-transform-function-snippets-and-add-to-your-template-with-aws-include-transform.html)
    and AWS::Serverless (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/transform-aws-serverless.html)
    transforms, which are macros hosted by AWS CloudFormation.
 
 

Change sets do not currently support nested stacks. If you want to update

   a stack from a stack template that contains macros and nested stacks,
    you must update the stack directly from the template using this capability.
 
 

You should only update stacks directly from a stack template that contains

   macros if you know what processing the macro performs.
 
 

Each macro relies on an underlying Lambda service function for processing

   stack templates. Be aware that the Lambda function owner can update the
    function operation without AWS CloudFormation being notified.

   Processing on Templates (http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-macros.html).
 

Type: *string

A unique identifier for this UpdateStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to update a stack with the same name. You might retry UpdateStack requests to ensure that AWS CloudFormation successfully received them.

All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a CreateStack operation with the token token1, then all the StackEvents generated by that operation will have ClientRequestToken set as token1.

In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID, which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002.

Type: []*string

Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that AWS CloudFormation associates with the stack. Specify an empty list to remove all notification topics.

The Parameter data type.

Type: []*string

The template resource types that you have permissions to work with for this update stack action, such as AWS::EC2::Instance, AWS::EC2::*, or Custom::MyCustomInstance.

If the list of resource types doesn't include a resource that you're updating, the stack update fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with AWS Identity and Access Management (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html).

Type: *string

The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to update the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.

If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.

Structure containing the rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.

Rollback triggers enable you to have AWS CloudFormation monitor the state of your application during stack creation and updating, and to roll back that operation if the application breaches the threshold of any of the alarms you've specified. For more information, see Monitor and Roll Back Stack Operations (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-rollback-triggers.html).

Type: *string

The name or unique stack ID of the stack to update.

StackName is a required field

Type: *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.

Type: *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.

Type: *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.

Type: *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.

The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.

Type: *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 (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html) in the AWS CloudFormation User Guide.)

Conditional: You must specify only one of the following parameters: TemplateBody, TemplateURL, or set the UsePreviousTemplate to true.

Type: *string

Location of file containing the template body. The URL must point to a template that is located in an Amazon S3 bucket. For more information, go to Template Anatomy (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html) in the AWS CloudFormation User Guide.

Conditional: You must specify only one of the following parameters: TemplateBody, TemplateURL, or set the UsePreviousTemplate to true.

Type: *bool

Reuse the existing template that is associated with the stack that you are updating.

Conditional: You must specify only one of the following parameters: TemplateBody, TemplateURL, or set the UsePreviousTemplate to true.
