 'ResourcesToImport': [{'LogicalResourceId': 'string',
                        'ResourceIdentifier': {'string': 'string'},
                        'ResourceType': 'string'}]}

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 AWS CloudFormation will create. If you create a change set for an existing stack, AWS 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 AWS 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, AWS 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. AWS CloudFormation doesn't make changes until you execute the change set.

type StackName:

string

param StackName:

[REQUIRED]

The name or the unique ID of the stack for which you are creating a change set. AWS CloudFormation generates the change set by comparing this stack's information with the information that you submit, such as a modified template or different parameter input values.

type TemplateBody:

string

param TemplateBody:

A structure that contains the body of the revised template, with a minimum length of 1 byte and a maximum length of 51,200 bytes. AWS CloudFormation generates the change set by comparing this template with the template of the stack that you specified.

Conditional: You must specify only TemplateBody or TemplateURL.

type TemplateURL:

string

param TemplateURL:

The location of the file that contains the revised template. The URL must point to a template (max size: 460,800 bytes) that is located in an S3 bucket. AWS CloudFormation generates the change set by comparing this template with the stack that you specified.

Conditional: You must specify only TemplateBody or TemplateURL.

type UsePreviousTemplate:

boolean

param UsePreviousTemplate:

Whether to reuse the template that is associated with the stack to create the change set.

type Parameters:

list

param Parameters:

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

    • ResolvedValue (string) --

      Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for SSM parameter types in the template.

type Capabilities:

list

param Capabilities:

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

  • CAPABILITY_IAM and CAPABILITY_NAMED_IAM 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.

For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates.

  • CAPABILITY_AUTO_EXPAND 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 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 AWS CloudFormation.

  • (string) --

type ResourceTypes:

list

param ResourceTypes:

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, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for condition keys in IAM policies for AWS CloudFormation. For more information, see Controlling Access with AWS Identity and Access Management in the AWS CloudFormation User Guide.

  • (string) --

type RoleARN:

string

param RoleARN:

The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes when executing the change set. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation 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.

type RollbackConfiguration:

dict

param RollbackConfiguration:

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

  • RollbackTriggers (list) --

    The triggers to monitor during stack creation or update actions.

    By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:

    • To use the rollback triggers previously specified for this stack, if any, don't specify this parameter.

    • To specify new or updated rollback triggers, you must specify all the triggers that you want used for this stack, even triggers you've specifed before (for example, when creating the stack or during a previous stack update). Any triggers that you don't include in the updated list of triggers are no longer applied to the stack.

    • To remove all currently specified triggers, specify an empty list for this parameter.

    If a specified trigger is missing, the entire stack operation fails and is rolled back.

    • (dict) --

      A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.

      • Arn (string) -- [REQUIRED]

        The Amazon Resource Name (ARN) of the rollback trigger.

        If a specified trigger is missing, the entire stack operation fails and is rolled back.

      • Type (string) -- [REQUIRED]

        The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.

  • MonitoringTimeInMinutes (integer) --

    The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.

    The default is 0 minutes.

    If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack, for example) as necessary.

    If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.

type NotificationARNs:

list

param NotificationARNs:

The Amazon Resource Names (ARNs) of Amazon Simple Notification Service (Amazon SNS) topics that AWS CloudFormation associates with the stack. To remove all associated notification topics, specify an empty list.

  • (string) --

type Tags:

list

param Tags:

Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to resources in the stack. You can specify a maximum of 50 tags.

  • (dict) --

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

    • Key (string) -- [REQUIRED]

      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:.

    • Value (string) -- [REQUIRED]

      Required. A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.

type ChangeSetName:

string

param ChangeSetName:

[REQUIRED]

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 alphabetic character and cannot exceed 128 characters.

type ClientToken:

string

param ClientToken:

A unique identifier for this CreateChangeSet request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to create another change set with the same name. You might retry CreateChangeSet requests to ensure that AWS CloudFormation successfully received them.

type Description:

string

param Description:

A description to help you identify this change set.

type ChangeSetType:

string

param 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, AWS 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, AWS 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.

type ResourcesToImport:

list

param ResourcesToImport:

The resources to import into your stack.

  • (dict) --

    Describes the target resource of an import operation.

    • ResourceType (string) -- [REQUIRED]

      The type of resource to import into your stack, such as AWS::S3::Bucket.

    • LogicalResourceId (string) -- [REQUIRED]

      The logical ID of the target resource as specified in the template.

    • ResourceIdentifier (dict) -- [REQUIRED]

      A key-value pair that identifies the target resource. The key is an identifier property (for example, BucketName for AWS::S3::Bucket resources) and the value is the actual property value (for example, MyS3Bucket).

      • (string) --

        • (string) --

rtype:

dict

returns:

            The Amazon Resource Name (ARN) of the rollback trigger.

            If a specified trigger is missing, the entire stack operation fails and is rolled back.

          • Type (string) --

            The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.

      • MonitoringTimeInMinutes (integer) --

      • (dict) --

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

        • Value (string) --

          Required. A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.

    • Changes (list) --

      A list of Change structures that describes the resources AWS CloudFormation changes if you execute the change set.

      • (dict) --

        The Change structure describes the changes AWS CloudFormation will perform if you execute the change set.

        • Type (string) --

          The type of entity that AWS CloudFormation changes. Currently, the only entity type is Resource.

        • ResourceChange (dict) --

          A ResourceChange structure that describes the resource and action that AWS CloudFormation will perform.

          • Action (string) --

            The action that AWS CloudFormation takes on the resource, such as Add (adds a new resource), Modify (changes a resource), or Remove (deletes a resource).

          • LogicalResourceId (string) --

            The resource's logical ID, which is defined in the stack's template.

          • PhysicalResourceId (string) --

            The resource's physical ID (resource name). Resources that you are adding don't have physical IDs because they haven't been created.

          • ResourceType (string) --

            The type of AWS CloudFormation resource, such as AWS::S3::Bucket.

          • Replacement (string) --

            For the Modify action, indicates whether AWS CloudFormation will replace the resource by creating a new one and deleting the old one. This value depends on the value of the RequiresRecreation property in the ResourceTargetDefinition structure. For example, if the RequiresRecreation field is Always and the Evaluation field is Static, Replacement is True. If the RequiresRecreation field is Always and the Evaluation field is Dynamic, Replacement is Conditionally.

            If you have multiple changes with different RequiresRecreation values, the Replacement value depends on the change with the most impact. A RequiresRecreation value of Always has the most impact, followed by Conditionally, and then Never.

          • Scope (list) --

            For the Modify action, indicates which resource attribute is triggering this update, such as a change in the resource attribute's Metadata, Properties, or Tags.

          • Details (list) --

            For the Modify action, a list of ResourceChangeDetail structures that describes the changes that AWS CloudFormation will make to the resource.

            • (dict) --

              For a resource with Modify as the action, the ResourceChange structure describes the changes AWS CloudFormation will make to that resource.

              • Target (dict) --

                A ResourceTargetDefinition structure that describes the field that AWS CloudFormation will change and whether the resource will be recreated.

                • Attribute (string) --

                  Indicates which resource attribute is triggering this update, such as a change in the resource attribute's Metadata, Properties, or Tags.

                  If the Attribute value is Properties, the name of the property. For all other attributes, the value is null.

                • RequiresRecreation (string) --

                  If the Attribute value is Properties, indicates whether a change to this property causes the resource to be recreated. The value can be Never, Always, or Conditionally. To determine the conditions for a Conditionally recreation, see the update behavior for that property in the AWS CloudFormation User Guide.

              • Evaluation (string) --

                Indicates whether AWS CloudFormation can determine the target value, and whether the target value will change before you execute a change set.

                For Static evaluations, AWS CloudFormation can determine that the target value will change, and its value. For example, if you directly modify the InstanceType property of an EC2 instance, AWS CloudFormation knows that this property value will change, and its value, so this is a Static evaluation.

                For Dynamic evaluations, cannot determine the target value because it depends on the result of an intrinsic function, such as a Ref or Fn::GetAtt intrinsic function, when the stack is updated. For example, if your template includes a reference to a resource that is conditionally recreated, the value of the reference (the physical ID of the resource) might change, depending on if the resource is recreated. If the resource is recreated, it will have a new physical ID, so all references to that resource will also be updated.

              • ChangeSource (string) --

                The group to which the CausingEntity value belongs. There are five entity groups:

                • ResourceReference entities are Ref intrinsic functions that refer to resources in the template, such as { "Ref" : "MyEC2InstanceResource" }.

                • ParameterReference entities are Ref intrinsic functions that get template parameter values, such as { "Ref" : "MyPasswordParameter" }.

                • ResourceAttribute entities are Fn::GetAtt intrinsic functions that get resource attribute values, such as { "Fn::GetAtt" : [ "MyEC2InstanceResource", "PublicDnsName" ] }.

                • DirectModification entities are changes that are made directly to the template.

                • Automatic entities are AWS::CloudFormation::Stack resource types, which are also known as nested stacks. If you made no changes to the AWS::CloudFormation::Stack resource, AWS CloudFormation sets the ChangeSource to Automatic because the nested stack's template might have changed. Changes to a nested stack's template aren't visible to AWS CloudFormation until you run an update on the parent stack.

              • CausingEntity (string) --

                The identity of the entity that triggered this change. This entity is a member of the group that is specified by the ChangeSource field. For example, if you modified the value of the KeyPairName parameter, the CausingEntity is the name of the parameter ( KeyPairName).

                If the ChangeSource value is DirectModification, no value is given for CausingEntity.

    • NextToken (string) --

      If the output exceeds 1 MB, a string that identifies the next page of changes. If there is no additional page, this value is null.

        • PhysicalResourceId (string) --

          The name or unique identifier associated with the physical instance of the resource.

        • ResourceType (string) --

          Type of resource. (For more information, go to AWS Resource Types Reference in the AWS CloudFormation User Guide.)

        • Timestamp (datetime) --

          Time the status was updated.

        • ResourceStatus (string) --

          Current status of the resource.

        • ResourceStatusReason (string) --

          Success/failure message associated with the resource.

        • ResourceProperties (string) --

          BLOB of the properties used to create the resource.

        • ClientRequestToken (string) --

          The token passed to the operation that generated this event.

          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.

    • NextToken (string) --

      If the output exceeds 1 MB in size, a string that identifies the next page of events. If no additional page exists, this value is null.

            • 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 input 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.

            • ResolvedValue (string) --

              Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for SSM parameter types in the template.

        • CreationTime (datetime) --

          The time at which the stack was created.

        • DeletionTime (datetime) --

          The time the stack was deleted.

        • LastUpdatedTime (datetime) --

          The time the stack was last updated. This field will only be returned if the stack has been updated at least once.

        • RollbackConfiguration (dict) --

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

          • RollbackTriggers (list) --

            The triggers to monitor during stack creation or update actions.

            By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:

            • To use the rollback triggers previously specified for this stack, if any, don't specify this parameter.

            • To specify new or updated rollback triggers, you must specify all the triggers that you want used for this stack, even triggers you've specifed before (for example, when creating the stack or during a previous stack update). Any triggers that you don't include in the updated list of triggers are no longer applied to the stack.

            • To remove all currently specified triggers, specify an empty list for this parameter.

            If a specified trigger is missing, the entire stack operation fails and is rolled back.

            • (dict) --

              A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.

              • Arn (string) --

                The Amazon Resource Name (ARN) of the rollback trigger.

                If a specified trigger is missing, the entire stack operation fails and is rolled back.

              • Type (string) --

                The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.

          • MonitoringTimeInMinutes (integer) --

            The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.

            The default is 0 minutes.

            If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack, for example) as necessary.

            If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.

        • StackStatus (string) --

          Current status of the stack.

        • StackStatusReason (string) --

          Success/failure message associated with the stack status.

        • DisableRollback (boolean) --

          Boolean to enable or disable rollback on stack creation failures:

          • true: disable rollback

          • false: enable rollback

        • NotificationARNs (list) --

          SNS topic ARNs to which stack related events are published.

          • (string) --

        • TimeoutInMinutes (integer) --

          The amount of time within which stack creation should complete.

        • Capabilities (list) --

          The capabilities allowed in the stack.

          • (string) --

        • Outputs (list) --

        • RoleARN (string) --

          The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that is associated with the stack. During a stack operation, AWS CloudFormation uses this role's credentials to make calls on your behalf.

        • Tags (list) --

          A list of ``Tag``s that specify information about the stack.

          • (dict) --

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

            • Value (string) --

              Required. A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.

        • EnableTerminationProtection (boolean) --

          Whether termination protection is enabled for the stack.

          For nested stacks, termination protection is set on the root stack and cannot be changed directly on the nested stack. For more information, see Protecting a Stack From Being Deleted in the AWS CloudFormation User Guide.

        • ParentId (string) --

          For nested stacks--stacks created as resources for another stack--the stack ID of the direct parent of this stack. For the first level of nested stacks, the root stack is also the parent stack.

          For more information, see Working with Nested Stacks in the AWS CloudFormation User Guide.

        • RootId (string) --

          For nested stacks--stacks created as resources for another stack--the stack ID of the top-level stack to which the nested stack ultimately belongs.

          For more information, see Working with Nested Stacks in the AWS CloudFormation User Guide.

        • DriftInformation (dict) --

          Information on whether a stack's actual configuration differs, or has drifted, from it's expected configuration, as defined in the stack template and any values specified as template parameters. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources.

          • StackDriftStatus (string) --

            Status of the stack's actual configuration compared to its expected template configuration.

            • DRIFTED: The stack differs from its expected template configuration. A stack is considered to have drifted if one or more of its resources have drifted.

            • NOT_CHECKED: AWS CloudFormation has not checked if the stack differs from its expected template configuration.

            • IN_SYNC: The stack's actual configuration matches its expected template configuration.

            • UNKNOWN: This value is reserved for future use.

          • LastCheckTimestamp (datetime) --

            Most recent time when a drift detection operation was initiated on the stack, or any of its individual resources that support drift detection.

    • NextToken (string) --

      If the output exceeds 1 MB in size, a string that identifies the next page of stacks. If no additional page exists, this value is null.

Returns information about a new or existing template. The GetTemplateSummary action is useful for viewing parameter information, such as default parameter values and parameter types, before you create or update a stack or stack set.

You can use the GetTemplateSummary action when you submit a template, or you can get template information for a stack set, or a running or deleted stack.

For deleted stacks, GetTemplateSummary returns the template information for up to 90 days after the stack has been deleted. If the template does not exist, a ValidationError is returned.

          The time the stack was deleted.

        • StackStatus (string) --

          The current status of the stack.

        • StackStatusReason (string) --

          Success/Failure message associated with the stack status.

        • ParentId (string) --

          For nested stacks--stacks created as resources for another stack--the stack ID of the direct parent of this stack. For the first level of nested stacks, the root stack is also the parent stack.

          For more information, see Working with Nested Stacks in the AWS CloudFormation User Guide.

        • RootId (string) --

          For nested stacks--stacks created as resources for another stack--the stack ID of the top-level stack to which the nested stack ultimately belongs.

          For more information, see Working with Nested Stacks in the AWS CloudFormation User Guide.

        • DriftInformation (dict) --

          Summarizes information on whether a stack's actual configuration differs, or has drifted, from it's expected configuration, as defined in the stack template and any values specified as template parameters. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources.

          • StackDriftStatus (string) --

            Status of the stack's actual configuration compared to its expected template configuration.

            • DRIFTED: The stack differs from its expected template configuration. A stack is considered to have drifted if one or more of its resources have drifted.

            • NOT_CHECKED: AWS CloudFormation has not checked if the stack differs from its expected template configuration.

            • IN_SYNC: The stack's actual configuration matches its expected template configuration.

            • UNKNOWN: This value is reserved for future use.

          • LastCheckTimestamp (datetime) --

            Most recent time when a drift detection operation was initiated on the stack, or any of its individual resources that support drift detection.

    • NextToken (string) --

      If the output exceeds 1 MB in size, a string that identifies the next page of stacks. If no additional page exists, this value is null.
