type Controller struct {

}

The SSM Invalidation controller is responsible for invalidating "latest" SSM parameters when they point to deprecated AMIs. This can occur when an EKS-optimized AMI with a regression is released, and the AMI team chooses to deprecate the AMI. Normally, SSM parameter cache entries expire after 24 hours to prevent a thundering herd upon a new AMI release, however Karpenter should react faster when an AMI is deprecated. This controller will ensure Karpenter reacts to AMI deprecations within it's polling period (30m).
