Updating your goodies in CloudFormation Stacks

Goal:

Wanna see what happens when one can update CloudFormation stacks w/direct updates & use change sets to update the stack? Well sit back & watch the show.

Lessons Learned:

  • Deploy a stack using AWS CloudFormation Templates
  • Update stack to scale up
  • Update stack to scale out

Deploy a stack using AWS CloudFormation Templates:

  • After downloading the stack, go create key pair. What are you waiting for? Go, quick, run, go!
  • Remember the slick view one can peer into?!
  • Hope your stackin like this?

Update stack to scale up:

  • Yeah, you know what to do. Update the stack EC2 instance to medium. Just do it.
  • To double-check your work, snag that http above in “value”.
    • See the same test page below!?

Update stack to scale out:

  • Lastly snag that bottom yaml file & re-upload into your stack #CHAAAAANGE
  • Difference here is we have 2 new instances added
  • Scroll to bottom of seeing the summary of changes
  • And like before, see the changes happening live!
    • I know, fancy – ooooo ahhhh
