Description

Creates a list of changes that will be applied to a stack so that you can review the changes before executing them. You can create a change set for a stack that doesn't exist or an existing stack. If you create a change set for a stack that doesn't exist, the change set shows all of the resources that CloudFormation will create. If you create a change set for an existing stack, CloudFormation compares the stack's information with the information that you submit in the change set and lists the differences. Use change sets to understand which resources CloudFormation will create or change, and how it will change resources in an existing stack, before you create or update a stack. To create a change set for a stack that doesn't exist, for the ChangeSetType parameter, specify CREATE. To create a change set for an existing stack, specify UPDATE for the ChangeSetType parameter. To create a change set for an import operation, specify IMPORT for the ChangeSetType parameter. After the CreateChangeSet call successfully completes, CloudFormation starts creating the change set. To check the status of the change set or to review it, use the DescribeChangeSet action. When you are satisfied with the changes the change set will make, execute the change set by using the ExecuteChangeSet action. CloudFormation doesn't make changes until you execute the change set. To create a change set for the entire stack hierarchy, set IncludeNestedStacks to True.

Parameters

-Capability <String[]>
In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for CloudFormation to create the stack.
  • CAPABILITY_IAM and CAPABILITY_NAMED_IAMSome stack templates might include resources that can affect permissions in your Amazon Web Services account; for example, by creating new 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, 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.For more information, see Acknowledging IAM resources in CloudFormation templates.
  • CAPABILITY_AUTO_EXPANDSome 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 creating the stack. If your stack template contains one or more macros, and you choose to create 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 and AWS::Serverless transforms, which are macros hosted by CloudFormation.This capacity doesn't apply to creating change sets, and specifying it when creating change sets has no effect.If you want to create a stack from a stack template that contains macros and nested stacks, you must create or update the stack directly from the template using the CreateStack or UpdateStack action, and specifying this capability.For more information on macros, see Using CloudFormation macros to perform custom processing on templates.

AliasesCapabilities
-ChangeSetName <String>
The name of the change set. The name must be unique among all change sets that are associated with the specified stack.A change set name can contain only alphanumeric, case sensitive characters, and hyphens. It must start with an alphabetical character and can't exceed 128 characters.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-ChangeSetType <ChangeSetType>
The type of change set operation. To create a change set for a new stack, specify CREATE. To create a change set for an existing stack, specify UPDATE. To create a change set for an import operation, specify IMPORT.If you create a change set for a new stack, CloudFormation creates a stack with a unique stack ID, but no template or resources. The stack will be in the REVIEW_IN_PROGRESS state until you execute the change set.By default, CloudFormation specifies UPDATE. You can't use the UPDATE type to create a change set for a new stack or the CREATE type to create a change set for an existing stack.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientToken <String>
A unique identifier for this CreateChangeSet request. Specify this token if you plan to retry requests so that CloudFormation knows that you're not attempting to create another change set with the same name. You might retry CreateChangeSet requests to ensure that CloudFormation successfully received them.

The template resource types that you have permissions to work with if you execute this change set, such as AWS::EC2::Instance, AWS::EC2::*, or Custom::MyCustomInstance.If the list of resource types doesn't include a resource type that you're updating, the stack update fails. By default, CloudFormation grants permissions to all resource types. Identity and Access Management (IAM) uses this parameter for condition keys in IAM policies for CloudFormation. For more information, see Controlling access with Identity and Access Management in the CloudFormation User Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesResourceTypes
-RoleARN <String>
The Amazon Resource Name (ARN) of an Identity and Access Management (IAM) role that CloudFormation assumes when executing the change set. CloudFormation uses the role's credentials to make calls on your behalf. CloudFormation uses this role for all future operations on the stack. Provided that users have permission to operate on the stack, CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least permission.If you don't specify a value, CloudFormation uses the role that was previously associated with the stack. If no role is available, CloudFormation uses a temporary session that is generated from your user credentials.
