Execute 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, 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associated with the stack because they're no longer valid for the updated stack.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 for nested stacks (console)
-
In the 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.
-
In the navigation pane, choose Change sets to view a list
of the stack's change sets.
-
Choose the name of the root change set that you want to execute.
-
On the change set's details page, choose Execute change
set.
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 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.
