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a change set, CloudFormation deletes any additional change sets that are associated with the stack because they're no longer valid for the updated stack.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.
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.
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, CloudFormation starts updating the stack. To view the stack's progress, use the aws cloudformation describe-stacks command.
