Is there a way for a deployment or job to delete itself automatically after finished in kubernetes?

Is there a way for a Deployment or Job to completely delete itself upon completion?

I want it such that when I do kubectl get jobs/deployments/pods they don't show up after they finished (container exited).

One possible way I thought of was to call kubectl delete jobs/deployments/pods from within the container but I'm not sure if that's safe.

I found a related question and answer, but found out it is for CronJobs.

Following that answer, there is a TTL Controller introduced Alpha in 1.12 and Beta in 1.21. You have to manually enable it in Feature Gates before v1.21.

According to the docs:

provides a TTL (time to live) mechanism to limit the lifetime of resource objects that have finished execution. TTL controller only handles Jobs for now, and may be expanded to handle other resources that will finish execution, such as Pods and custom resources.

It could clean up Jobs currently and others in plan.
