In this video, learn what can be updated on a stack once it is created and how to perform such an update.
- [Instructor] Once a stack has been created,…CloudFormation allows you to update…the resources managed by the stack.…Updating a stack allows you to modify parameter…inputs or to change the template itself.…The resulting action will only update…the resources that you modify.…Be advised though that this action…could disrupt running services.…Finally, updating a stack comes in two flavors,…direct update or change sets.…Direct updates occur immediately.…Change sets on the other hand, introduce some additional…steps to make sure everything is going…to end up just the way you want.…
Change sets let you preview changes when updating a stack.…They clarify how CloudFormation will execute the change.…For example, will it update a resource…or delete and recreate it?…They do not indicate the successful outcome…of a change, however.…They can be executed right away or saved for later.…Finally, they expire once…the underlying template gets updated.…After all, a set of proposed changes might…not make any sense anymore once…the stack has been updated underneath it.…
