Executing a change set - AWS CloudFormation

Executing a change set

To make the changes described in a change set to your stack, execute the change set.

Important

After you execute a change set, AWS CloudFormation deletes any additional change sets that are associated with the stack because they are no longer valid for the updated stack. If an update fails, you need to create a new change set.

Stack Policies and Executing a Change Set

If you execute a change set on a stack that has a stack policy associated with it, AWS CloudFormation enforces the policy when it updates the stack. You can't specify a temporary stack policy that overrides the existing policy when you execute a change set. To update a protected resource, you must update the stack policy or use the direct update method.

Execute a change set for nested stacks (console)

To execute a change set for nested stacks (console)

  1. In the AWS CloudFormation console, in Stacks, choose the name the stack that you want to update. You must choose the stack name associated with the root change set.

  2. In the navigation pane, choose Change Sets to view a list of the stack's change sets.

  3. Choose the name of the root change set that you want to execute.

  4. On the change set's details page, choose Execute.

    Note

    AWS CloudFormation executes the changes described in your root change set and nested change sets, if Enabled for change sets for nested stacks was selected during the Creating a change set process.

    AWS CloudFormation immediately starts updating the stack. The AWS CloudFormation console directs you to the Events tab, where you can monitor the progress of the stack update.

To execute a change set (AWS CLI)

  • Run the aws cloudformation execute-change-set command.

    Specify the change set ID of the change set that you want to execute, as shown in the following example:

    aws cloudformation execute-change-set --change-set-name arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet/1a2345b6-0000-00a0-a123-00abc0abc000

    The command in the example executes a change set with the ID arn:aws:cloudformation:us-east-1:123456789012:changeSet/SampleChangeSet/1a2345b6-0000-00a0-a123-00abc0abc000.

    After you run the command, AWS CloudFormation starts updating the stack. To view the stack's progress, use the aws cloudformation describe-stacks command.
