Teardown EKS Quick Start Stack

This will remove the EKS cluster and all that it contains.

  1. Open the AWS CloudFormation console and on the upper right, in the region selector Select us-east-2
  2. Set ‘View nested’ (toggle) to off
  3. Select the stack that created the EKS cluster (default name for these docs = spot2azuseast2)
  4. In the upper right, Click Delete (button)

Optionally Remove the Advanced Configuration Stack

The advanced configuration stack only hold parameters and does not consume any resources, if you might use it again to redeploy a stack with the same configuration, it is more efficient to not tear it down.

  4. In the upper right, Click Delete (button)
