Stack Name Bulletin For Free

If you don't specify a name, CloudFormation generates a unique physical ID to name the resource. Names must begin with a letter; contain only ASCII letters, digits, and hyphens; and not end with a hyphen or contain two consecutive hyphens. Also, don't manage stack resources outside of CloudFormation.

To update a AWS CloudFormation stack (AWS CLI) Use the aws cloudformation update-stack command to directly update a stack. You specify the stack, and parameter values and capabilities that you want to update, and, if you want use an updated template, the name of the template.

No, it's not possible to change an existing stack's name, either with or without the CDK. Under the hood, cdk deploy sets the stack name with the CloudFormation CreateChangeSet API (then ExecuteChangeSet) on create. The stack name is a unique, immutable id in CloudFormation.

AWS CloudFormation has an overall limit of 128 characters for the name of a stack. Stax adds a 36-character identifier (a UUID) to the CloudFormation stack name. This is to ensure that the stack can be properly assigned against the Workload.

After you delete the stack and verify that the resource was retained, you launch another CloudFormation stack with a different name and import the resource. The result is a new stack with a different name from the original (meeting your security guidelines) but with the same resource as the original stack.

If so, then you probably know that the only way to change the stack name is to delete the original stack and recreate a new one with the updated name. This task might seem easy enough, until you discover that you still need the resources that were deployed with the original stack.

It must start with an alphabetical character and can't be longer than 128 characters. Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. For more information, go to Template anatomy in the CloudFormation User Guide.
