Update Stack

cloudformation_update_stack

R Documentation

Updates a stack as specified in the template

Description

Updates a stack as specified in the template. After the call completes successfully, the stack update starts. You can check the status of the stack through the describe_stacks action.

To get a copy of the template for an existing stack, you can use the get_template action.

For more information about updating a stack and monitoring the progress of the update, see Managing Amazon Web Services resources as a single unit with CloudFormation stacks in the CloudFormation User Guide.

Arguments

StackName	[required] The name or unique stack ID of the stack to update.
TemplateBody	Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. Conditional: You must specify only one of the following parameters: TemplateBody, TemplateURL, or set the UsePreviousTemplate to true.
TemplateURL	The URL of a file containing the template body. The URL must point to a template that's located in an Amazon S3 bucket or a Systems Manager document. The location for an Amazon S3 bucket must start with ⁠https://⁠. Conditional: You must specify only one of the following parameters: TemplateBody, TemplateURL, or set the UsePreviousTemplate to true.
UsePreviousTemplate	Reuse the existing template that is associated with the stack that you are updating. Conditional: You must specify only one of the following parameters: TemplateBody, TemplateURL, or set the UsePreviousTemplate to true.
StackPolicyDuringUpdateBody	Structure containing the temporary overriding stack policy body. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both. If you want to update protected resources, specify a temporary overriding stack policy during this update. If you don't specify a stack policy, the current policy that is associated with the stack will be used.
StackPolicyDuringUpdateURL	Location of a file containing the temporary overriding stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same Region as the stack. The location for an Amazon S3 bucket must start with ⁠https://⁠. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both. If you want to update protected resources, specify a temporary overriding stack policy during this update. If you don't specify a stack policy, the current policy that is associated with the stack will be used.
Parameters	A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.
Capabilities	In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for CloudFormation to update the stack. CAPABILITY_IAM and CAPABILITY_NAMED_IAM Some stack templates might include resources that can affect permissions in your Amazon Web Services account, for example, by creating new 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 suggest that you review all permissions associated with them and edit their permissions if necessary. AWS::IAM::AccessKey AWS::IAM::Group AWS::IAM::InstanceProfile AWS::IAM::ManagedPolicy AWS::IAM::Policy AWS::IAM::Role AWS::IAM::User AWS::IAM::UserToGroupAddition For more information, see Acknowledging IAM resources in 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 CloudFormation. If you want to update a stack from a stack template that contains macros and nested stacks, you must update the stack directly from the template using this capability. You should only update stacks directly from a stack template that contains macros if you know what processing the macro performs. Each macro relies on an underlying Lambda service function for processing stack templates. Be aware that the Lambda function owner can update the function operation without CloudFormation being notified. For more information, see Perform custom processing on CloudFormation templates with template macros. Only one of the Capabilities and ResourceType parameters can be specified.
ResourceTypes	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, CloudFormation grants permissions to all resource types. IAM uses this parameter for CloudFormation-specific condition keys in IAM policies. For more information, see Control access with Identity and Access Management. Only one of the Capabilities and ResourceType parameters can be specified.
RoleARN	The Amazon Resource Name (ARN) of an IAM role that CloudFormation assumes to update the stack. CloudFormation uses the role's credentials to make calls on your behalf. CloudFormation always 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 privilege. 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.
RollbackConfiguration	The rollback triggers for CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
StackPolicyBody	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 don't specify a stack policy, the current policy that is associated with the stack is unchanged.
StackPolicyURL	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. The location for an Amazon S3 bucket must start with ⁠https://⁠. 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 don't specify a stack policy, the current policy that is associated with the stack is unchanged.
NotificationARNs	Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that CloudFormation associates with the stack. Specify an empty list to remove all notification topics.
Tags	Key-value pairs to associate with this stack. 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, CloudFormation doesn't modify the stack's tags. If you specify an empty value, CloudFormation removes all associated tags.
DisableRollback	Preserve the state of previously provisioned resources when an operation fails. Default: False
ClientRequestToken	A unique identifier for this update_stack request. Specify this token if you plan to retry requests so that CloudFormation knows that you're not attempting to update a stack with the same name. You might retry update_stack requests to ensure that 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 create_stack 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.
RetainExceptOnCreate	When set to true, newly created resources are deleted when the operation rolls back. This includes newly created resources marked with a deletion policy of Retain. Default: false
