{'ResourcesToSkip': ['string']}
For a specified stack that is in the UPDATE_ROLLBACK_FAILED state, continues rolling it back to the UPDATE_ROLLBACK_COMPLETE state. Depending on the cause of the failure, you can manually fix the error and continue the rollback. By continuing the rollback, you can return your stack to a working state (the UPDATE_ROLLBACK_COMPLETE state), and then try to update the stack again.
A stack goes into the UPDATE_ROLLBACK_FAILED state when AWS CloudFormation cannot roll back all changes after a failed stack update. For example, you might have a stack that is rolling back to an old database instance that was deleted outside of AWS CloudFormation. Because AWS CloudFormation doesn't know the database was deleted, it assumes that the database instance still exists and attempts to roll back to it, causing the update rollback to fail.
Request Syntax
client.continue_update_rollback(
StackName='string',
RoleARN='string',
ResourcesToSkip=[
'string',
]
)
string
[REQUIRED]
The name or the unique ID of the stack that you want to continue rolling back.
Note
Don't specify the name of a nested stack (a stack that was created by using the AWS::CloudFormation::Stack resource). Instead, use this operation on the parent stack (the stack that contains the AWS::CloudFormation::Stack resource).
string
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to roll back 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.
list
A list of the logical IDs of the resources that AWS CloudFormation skips during the continue update rollback operation. You can specify only resources that are in the UPDATE_FAILED state because a rollback failed. You can't specify resources that are in the UPDATE_FAILED state for other reasons, for example, because an update was canceled. To check why a resource update failed, use the DescribeStackResources action, and view the resource status reason.
Warning
Specify this property to skip rolling back resources that AWS CloudFormation can't successfully roll back. We recommend that you troubleshoot resources before skipping them. AWS CloudFormation sets the status of the specified resources to UPDATE_COMPLETE and continues to roll back the stack. After the rollback is complete, the state of the skipped resources will be inconsistent with the state of the resources in the stack template. Before performing another stack update, you must update the stack or resources to be consistent with each other. If you don't, subsequent stack updates might fail, and the stack will become unrecoverable.
Specify the minimum number of resources required to successfully roll back your stack. For example, a failed resource update might cause dependent resources to fail. In this case, it might not be necessary to skip the dependent resources.
To specify resources in a nested stack, use the following format: NestedStackName.ResourceLogicalID . You can specify a nested stack resource (the logical ID of an AWS::CloudFormation::Stack resource) only if it's in one of the following states: DELETE_IN_PROGRESS , DELETE_COMPLETE , or DELETE_FAILED .

{'ChangeSetType': 'CREATE | UPDATE'}
Response {'StackId': 'string'}
Creates a list of changes for a stack. AWS CloudFormation generates the change set by comparing the template's information with the information that you submit. A change set can help you understand which resources AWS CloudFormation will change, and how it will change them, before you update your stack. Change sets allow you to check before making a change to avoid deleting or replacing critical resources.
AWS CloudFormation doesn't make any changes to the stack when you create a change set. To make the specified changes, you must execute the change set by using the ExecuteChangeSet action.
After the call successfully completes, AWS CloudFormation starts creating the change set. To check the status of the change set, use the DescribeChangeSet action.
Request Syntax

)
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 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.
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 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.
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 10 tags.

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. Valid values are CREATE and UPDATE :
CREATE - Specify for a change set for a stack that does not yet exist. The stack has an expected unique ID, but no template or resources. It can include multiple change sets.
UPDATE - Specify for a change set for an existing stack.
