Cloudformation changesets

0

I am in the need to update a Cloudformation stack that has references of another stack. I created a changeset with the updated template and modified the reference to the actual value. The value of change is the web-acl ID. I am hoping that the minor change I made does not recreate the load balancers. My question is, if I only change the web-acl reference to the value of the actual ID, does it recreate everything when I commit the change.

Hi ,

CloudFormation updates the stack. If there is a diff, it will create the resources and rest of things are updated.

To have a better view, follow below steps:

  • Go to Cloud Formation console.
  • Select your stack. It will take you to stack detail page.
  • Click on Events header ( next to Stack Info ). It will provide granular details on what resources is being created & what is updated.

    I see these changes in the gui and cli, so I think I am good, it's just changing a web-acl ID.

    "Details": [ { "Target": { "Attribute": "Properties", "Name": "WebACLId", "RequiresRecreation": "Conditionally" }, "Evaluation": "Static", "ChangeSource": "DirectModification"

    Thanks for your help.
