kubernetes: Cannot get TTLAfterFinished to work in 1.12.1

What happened: Trying to enable the TTLAfterFinished feature gate to use the Job cleanup feature, and the feature does not work after enabling. What you expected to happen: The Job to be deleted 100s after hitting the Completed state. How to reproduce it (as minimally and precisely as possible): I added the following to the api-server and controller manifests: –feature-gates=“TTLAfterFinished=true” After a restart, both show the item present. Then launched a Job with “ttlSecondsAfterFinished: 100” set under .spec. Anything else we need to know?:

Environment:

Kubernetes version (use kubectl version): 1.12.1
Cloud provider or hardware configuration: Bare metal
OS (e.g. from /etc/os-release): Ubuntu 18.04
Kernel (e.g. uname -a): 4.15.0-34-generic
Install tools: kubespray
Others:

/kind bug

TTLAfterFinished not working for me either. Am I doing it right?

Could it be that I have quotes around the feature-gate?

Also: https://github.com/kubernetes/minikube/issues/3805

It does seem to work for me:

$ minikube start --feature-gates="TTLAfterFinished=true"
$ kubectl apply -f my-cron.yml
cronjob.batch/my-cron-1 created

(where my-cron.yml contains ttlSecondsAfterFinished)

$ minikube version
minikube version: v0.34.1
