Execute a change set for a CloudFormation stack - AWS CloudFormation

Execute a change set for a CloudFormation stack

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

Important

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a change set, CloudFormation deletes any additional change sets that are associated with the stack because they're no longer valid for the updated stack.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

Note

If the change set was created with express mode (--deployment-config '{"mode": "EXPRESS"}'), CloudFormation applies express mode when you execute the change set. Express mode completes resource operations as soon as configuration is applied, without waiting for full stabilization. For more information, see Express mode.

Stack policies and executing a change set

If you execute a change set on a stack that has a stack policy associated with it, 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. For more information, see Update stacks directly.

Execute a change set (console)
To execute a change set

  1. Open the CloudFormation console at https://console.aws.amazon.com/cloudformation.

  2. On the navigation bar at the top of the screen, choose your AWS Region.

  3. On the Stacks page, choose the name the stack that you want to update.

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

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

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

    CloudFormation immediately starts updating the stack. The CloudFormation console directs you to the Events tab, where you can monitor the progress of the stack update. For more information, see Monitor stack progress.

Execute a change set for nested stacks (console)
To execute a change set for nested stacks

  1. Open the CloudFormation console at https://console.aws.amazon.com/cloudformation.

  2. On the navigation bar at the top of the screen, choose your AWS Region.

  3. On the Stacks page, choose the name the stack that you want to update. You must choose the stack name associated with the root change set.

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

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

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

    Note

    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 Create a change set for a CloudFormation stack process.

    CloudFormation immediately starts updating the stack. The CloudFormation console directs you to the Events tab, where you can monitor the progress of the stack update. For more information, see Monitor stack progress.

To execute a change set (AWS CLI)

  • Run the 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, CloudFormation starts updating the stack. To view the stack's progress, use the describe-stacks command.
