Executing a Change Set
To make the changes described in a change set to your stack, execute the change set.
After you execute a change set, AWS CloudFormation deletes all change sets that are associated with the stack because they aren't 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.
To execute a change set (console)
In the AWS CloudFormation console, choose the stack that you want to update.
In the stack detail pane, choose Change Sets to view a list of the stack's change sets.
Choose the change set that you want execute.
The AWS CloudFormation console directs you to the detail page of the change set.
Confirm that this is the change set you want to execute, and then choose Execute.
AWS CloudFormation immediately starts updating the stack. You can monitor the progress of the update by viewing the Events tab.
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:Copy
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
After you run the command, AWS CloudFormation starts updating the stack. To view the stack's progress, use the aws cloudformation describe-stacks command.
