2018/11/19 - AWS CloudFormation - 10 updated api methods
Changes Use the CAPABILITY_AUTO_EXPAND capability to create or update a stack directly from a stack template that contains macros, without first reviewing the resulting changes in a change set first.
{'Capabilities': ['CAPABILITY_AUTO_EXPAND']}
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. 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.

string
[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.
string
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 .
string
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 .
boolean
Whether to reuse the template that is associated with the stack to create the change set.
list
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 <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
list
A list of values that you must specify before AWS CloudFormation can update certain stacks. 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 their capabilities by specifying this parameter.
The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM . The following resources require you to specify this parameter: 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 all permissions associated with them and edit their permissions if necessary.
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 this parameter, this action returns an InsufficientCapabilities error.
For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .
(string) --
list
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) --
string
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.
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) -- [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.
list
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) --
list
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.
string
[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.
string
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.
string
A description to help you identify this change set.
string
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 .
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 http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-describing-stacks.html#d0e11995`__ 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.

Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
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
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.

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.
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) --
list
In some cases, you must explicity 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. Change sets do not currently support nested stacks. If you want to create a stack from a stack template that contains macros and nested stacks, you must create the stack directly from the template using this capability.
Warning
You should only create 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.
For more information, see Using AWS CloudFormation Macros to Perform Custom Processing on Templates .
(string) --
list
The template resource types that you have permissions to work with for this create stack action, such as AWS::EC2::Instance , AWS::EC2::* , or Custom::MyCustomInstance . Use the following syntax to describe template resource types: AWS::* (for all AWS resource), Custom::* (for all custom resources), Custom::*logical_ID* `` (for a specific custom resource), ``AWS::*service_name* ::* (for all resources of a particular AWS service), and ``AWS::service_name ::resource_logical_ID `` (for a specific AWS resource).
If the list of resource types doesn't include a resource that you're creating, the stack creation 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 .
(string) --
string
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to create 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.
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
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.
string
Location of a file containing the stack policy. The URL must point to a policy (maximum size: 16 KB) 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.
list
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to the resources created in the stack. A maximum number of 50 tags can be specified.
(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.
string
A unique identifier for this CreateStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to create a stack with the same name. You might retry CreateStack 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 .
boolean
Whether to enable termination protection on the specified stack. If a user attempts to delete a stack with termination protection enabled, the operation fails and the stack remains unchanged. For more information, see Protecting a Stack From Being Deleted in the AWS CloudFormation User Guide . Termination protection is disabled on stacks by default.
For nested stacks , termination protection is set on the root stack and cannot be changed directly on the nested stack.

The name of the change set.
ChangeSetId (string) --
The ARN of the change set.
StackId (string) --
The ARN of the stack that is associated with the change set.
StackName (string) --
The name of the stack that is associated with the change set.
Description (string) --
Information about the change set.
Parameters (list) --
A list of Parameter structures that describes the input parameters and their values used to create 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 <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
CreationTime (datetime) --
The start time when the change set was created, in UTC.
ExecutionStatus (string) --
If the change set execution status is AVAILABLE , you can execute the change set. If you can’t execute the change set, the status indicates why. For example, a change set might be in an UNAVAILABLE state because AWS CloudFormation is still creating it or in an OBSOLETE state because the stack was already updated.
Status (string) --
The current status of the change set, such as CREATE_IN_PROGRESS , CREATE_COMPLETE , or FAILED .
StatusReason (string) --
A description of the change set's status. For example, if your attempt to create a change set failed, AWS CloudFormation shows the error message.
NotificationARNs (list) --
The ARNs of the Amazon Simple Notification Service (Amazon SNS) topics that will be associated with the stack if you execute the change set.
(string) --
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.
Capabilities (list) --
If you execute the change set, the list of capabilities that were explicitly acknowledged when the change set was created.
(string) --
Tags (list) --
If you execute the change set, the tags that will be associated with 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.
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 .
(string) --
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 .
Name (string) --
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.

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 <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
list
In some cases, you must explicity acknowledge that your stack template contains certain capabilities in order for AWS CloudFormation to update 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 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 and AWS::Serverless 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.
Warning
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.
For more information, see Using AWS CloudFormation Macros to Perform Custom Processing on Templates .
(string) --
list
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 .
(string) --
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.
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) -- [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.
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.
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.
list
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.
(string) --
list
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to supported resources in the stack. You can specify a maximum number of 50 tags.
If you don't specify this parameter, AWS CloudFormation doesn't modify the stack's tags. If you specify an empty value, AWS CloudFormation removes all associated 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.
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 .

Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
list
A list of values that you must specify before AWS CloudFormation can create certain stack sets. Some stack set 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 stack sets, you must explicitly acknowledge their capabilities by specifying this parameter.
The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM. The following resources require you to specify this parameter:
AWS::IAM::AccessKey
AWS::IAM::Group
AWS::IAM::InstanceProfile
AWS::IAM::Policy
AWS::IAM::Role
AWS::IAM::User
AWS::IAM::UserToGroupAddition
If your stack template contains these resources, we recommend that you review all permissions that are associated with them and edit their permissions if necessary.
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 this parameter, this action returns an InsufficientCapabilities error.
For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates.
(string) --
list
The key-value pairs to associate with this stack set and the stacks created from it. AWS CloudFormation also propagates these tags to supported resources that are created in the stacks. You can specify a maximum number of 50 tags.
If you specify tags for this parameter, those tags replace any list of tags that are currently associated with this stack set. This means:
If you don't specify this parameter, AWS CloudFormation doesn't modify the stack's tags.
If you specify any tags using this parameter, you must specify all the tags that you want associated with this stack set, even tags you've specifed before (for example, when creating the stack set or during a previous update of the stack set.). Any tags that you don't include in the updated list of tags are removed from the stack set, and therefore from the stacks and resources as well.
If you specify an empty value, AWS CloudFormation removes all currently associated tags.
If you specify new tags as part of an UpdateStackSet action, AWS CloudFormation checks to see if you have the required IAM permission to tag resources. If you omit tags that are currently associated with the stack set from the list of tags you specify, AWS CloudFormation assumes that you want to remove those tags from the stack set, and checks to see if you have permission to untag resources. If you don't have the necessary permission(s), the entire UpdateStackSet action fails with an access denied error, and the stack set is not updated.
(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.
dict
Preferences for how AWS CloudFormation performs this stack set operation.
RegionOrder (list) --
The order of the regions in where you want to perform the stack operation.
(string) --
FailureToleranceCount (integer) --
The number of accounts, per region, for which this operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).
FailureTolerancePercentage (integer) --
The percentage of accounts, per region, for which this stack operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage , but not both.
MaxConcurrentCount (integer) --
The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of FailureToleranceCount —MaxConcurrentCount is at most one more than the FailureToleranceCount .
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
MaxConcurrentPercentage (integer) --
The maximum percentage of accounts in which to perform this operation at one time.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
string
The Amazon Resource Number (ARN) of the IAM role to use to update this stack set.
Specify an IAM role only if you are using customized administrator roles to control which users or groups can manage specific stack sets within the same administrator account. For more information, see Define Permissions for Multiple Administrators in the AWS CloudFormation User Guide .
If you specify a customized administrator role, AWS CloudFormation uses that role to update the stack. If you do not specify a customized administrator role, AWS CloudFormation performs the update using the role previously associated with the stack set, so long as you have permissions to perform operations on the stack set.
string
The name of the IAM execution role to use to update the stack set. If you do not specify an execution role, AWS CloudFormation uses the AWSCloudFormationStackSetExecutionRole role for the stack set operation.
Specify an IAM role only if you are using customized execution roles to control which stack resources users and groups can include in their stack sets.
If you specify a customized execution role, AWS CloudFormation uses that role to update the stack. If you do not specify a customized execution role, AWS CloudFormation performs the update using the role previously associated with the stack set, so long as you have permissions to perform operations on the stack set.
string
The unique ID for this stack set operation.
The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You might retry stack set operation requests to ensure that AWS CloudFormation successfully received them.
If you don't specify an operation ID, AWS CloudFormation generates one automatically.
Repeating this stack set operation with a new operation ID retries all stack instances whose status is OUTDATED .
This field is autopopulated if not provided.
list
The accounts in which to update associated stack instances. If you specify accounts, you must also specify the regions in which to update stack set instances.
To update all the stack instances associated with this stack set, do not specify the Accounts or Regions properties.
If the stack set update includes changes to the template (that is, if the TemplateBody or TemplateURL properties are specified), or the Parameters property, AWS CloudFormation marks all stack instances with a status of OUTDATED prior to updating the stack instances in the specified accounts and regions. If the stack set update does not include changes to the template or parameters, AWS CloudFormation updates the stack instances in the specified accounts and regions, while leaving all other stack instances with their existing stack instance status.
