Validate stack deployments

With pre-deployment validation, you can identify and resolve potential deployment issues before executing your CloudFormation change sets. This feature validates your templates against common failure scenarios, helping you catch issues early in the development cycle.

How pre-deployment validation works

Pre-deployment validation involves these phases:

Create your change set – Generate a change set as you normally would for your CloudFormation stack updates. Pre-deployment validation is enabled by default when creating your change set.
Validation execution – CloudFormation runs multiple validation checks against your template and target environment. Currently 3 types of validation are supported: Property syntax validation against resource schemas, resource name conflict detection with existing resources, and S3 bucket emptiness validation for deletion operations.
Review validation results – CloudFormation provides detailed feedback on any issues found, including precise path pinpointing the issue location in template, eliminating manual template debugging.
Resolve issues – Address identified problems by updating your templates or resolving conflicts before proceeding with deployment.
Execute with confidence – Deploy your change set knowing that common failure scenarios have been validated upfront.

Considerations

As you use pre-deployment validation, keep the following in mind:

Pre-deployment validation focuses on the three common deployment failure scenarios. It doesn't guarantee that your deployment will succeed, but reduces the likelihood of common failures.
Validation modes behave differently:
- FAIL mode prevents change set execution when validation detects errors, ensuring problematic templates cannot proceed to deployment. This applies to property syntax errors and resource naming conflicts.
- WARN mode allows change set creation to succeed despite validation failures, providing warnings that developers can review and address before execution. This applies to constraint violations like S3 bucket emptiness that may be resolvable through manual intervention.
Validation results are tied to the specific change set. If you modify your template, you'll need to create a new change set to get updated validation results.
S3 bucket validation only checks for object presence, not for bucket policies or other constraints that might prevent deletion.

Prerequisites

To use pre-deployment validation, you must have:

The necessary IAM permissions to create change sets and read resources in your account. For S3 bucket emptiness check, you need s3:ListBucket permission.
Access to the Amazon Web Services Regions where your stacks are deployed.
CloudFormation templates that you want to validate before deployment.

Validate templates (console)

Use the following procedure to validate you deployment using the console.

To validate templates before deployment, create a change set

Sign in to the Amazon Web Services Management Console and open the Amazon CloudFormation console at https://console.amazonaws.cn/cloudformation.
On the navigation bar at the top of the screen, choose the Amazon Web Services Region where your stack is located.
On the Stacks page, choose the running stack you want to create a change set for.
In the stack details pane, choose Update Stack, and then choose Create a change set.
On the Create change set for stack-name page, upload your updated template or specify the template source.
Choose Next to proceed through the remaining change set configuration steps.
If the template includes IAM resources, for Capabilities, choose I acknowledge that CloudFormation might create IAM resources. IAM resources can modify permissions in your Amazon account; review these resources to ensure that you're permitting only the actions that you intend. For more information, see Acknowledging IAM resources in CloudFormation templates.
On the Review page, choose Create change set.
CloudFormation will create the change set and run validation checks. Review the validation results in the Deployment validation tab.
If validation passes or you're satisfied with the warnings, choose Execute Change set to deploy your changes.
If validation fails, fix the issues and create a new change set to re-validate your deployment.

Validate Deployment (Amazon CLI)

The Amazon CLI commands for pre-deployment validation include:

create-change-set automatically validating during change set creation.
describe-change-set to verify the change set status
describe-events to review validation results.

Use the following procedure to validate templates using the Amazon CLI.

To validate templates before deployment

Use the create-change-set command:
```
aws cloudformation create-change-set \
  --stack-name MyStack \
  --change-set-name MyChangeSet \
  --change-set-type "CREATE" \
  --template-body file://updated-template.yaml
```
The command returns a ChangeSetId that you can use to check validation results. You can also use the change set name to check the validation results.

Use the describe-events command to review validation status and results:


aws cloudformation describe-events \
  --change-set-id "arn:aws-cn:cloudformation:us-east-1:123456789012:changeSet/MyChangeSet/94498df5-1afb-43b1-9869-9f82b2d877ac"

Example output of a validation errors:


{
   "OperationEvents":[
      {
         "EventId":"9b5c9a29-4704-4ad0-8082-afb49418d55b",
         "StackId":"arn:aws-cn:cloudformation:us-east-1:123456789012:stack/MyStack/c3908380-b357-11f0-a97f-0ad08f35df65",
         "OperationId":"f558b823-e1e3-4de3-a222-e6b930ddcad4",
         "OperationType":"CREATE_CHANGESET",
         "OperationStatus":"FAILED",
         "EventType":"STACK_EVENT",

         "EndTime":"2025-10-27T17:10:02.923Z"
      },
      {
         "EventId":"2d8c3262-3468-4283-82fb-6e780e9e4f1d",
         "StackId":"arn:aws:cloudformation:us-east-1:123456789012:stack/MyStack/c3908380-b357-11f0-a97f-0ad08f35df65",
         "OperationId":"f558b823-e1e3-4de3-a222-e6b930ddcad4",
         "OperationType":"CREATE_CHANGESET",
         "EventType":"VALIDATION_ERROR",
         "LogicalResourceId":"NotificationBucket",
         "PhysicalResourceId":"",
         "ResourceType":"AWS::S3::Bucket",
         "Timestamp":"2025-10-27T17:10:02.461Z",
         "ValidationFailureMode":"FAIL",
         "ValidationName":"PROPERTY_VALIDATION",
         "ValidationStatus":"FAILED",
         "ValidationStatusReason":"#/NotificationConfiguration/QueueConfigurations/0: required key [Event] not found",
         "ValidationPath":"/Resources/NotificationBucket/Properties/NotificationConfiguration/QueueConfigurations/0"
      }
   ]
}

Address any validation errors by updating your template, then create a new change set.

Once validation passes, execute the change set:


aws cloudformation execute-change-set \
  --change-set-name MyChangeSet \
  --stack-name MyStack

Validation types

Pre-deployment validation includes the following types of checks:

Property Syntax Validation – Validates resource properties against Amazon resource schemas. It checks for required properties and valid property values and identifies deprecated or unsupported property combinations.
Resource Name Conflict Detection – Checks for naming conflicts with existing Amazon resources. It validates that resource names meet Amazon naming requirements and identifies potential conflicts before deployment attempts.
S3 Bucket Emptiness Validation – Warns when attempting to delete S3 buckets that contain objects. It provides object counts to help assess deletion impact and helps prevent common S3 deletion failures.

Each validation type provides specific error messages and with error location in the template to help you resolve issues quickly.
