Enable feature gates TTLAfterFinished

[rverma-nikiai]

Environment:

• AWS Region: ap-south-1
• Instance Type(s): r4.large
• EKS Platform version (use aws eks describe-cluster --name <name> --query cluster.platformVersion): eks.1
• Kubernetes version (use aws eks describe-cluster --name <name> --query cluster.version): 1.12
• AMI Version: ami-09c3eb35bb3be46a4

Wondering how can we enable a particular feature gate? Mostly TTLAfterFinished.

Hi @rverma-nikiai most managed Kubernetes Control Planes like EKS/GKE/AKE enable only Beta feature gates and do not enable any Alpha feature gates.

TTLAfterFinished is an Alpha feature for 1.12 and I would guess that AWS will not be enabling it until it graduates to be a Beta feature. AFAIK it is still Alpha in 1.14.

TTLAfterFinished is also a control plane feature, so it is not really relevant to the node AMI. You might be better to request it on the AWS containers team road map project.

@rverma-nikiai @whereisaaron summed it up pretty well. Can you open an issue on the roadmap, since this doesn't affect the AMI?
