How do I automatically remove completed Kubernetes

Question

Is there a way to automatically remove completed jobs besides making a cronjob to clean up completed jobs?

The K8s Job Documentation states that the intended behavior of completed jobs is for them to remain in a completed state until manually deleted. Because I am running thousands of jobs a day via k8s cronjobs and I don't want to keep completed jobs around.

Answer 1

You can now set history limits, or disable history altogether, so that failed or successful jobs are not kept around indefinitely. See my answer here. Documentation is here.

Answer 2

This is possible from version 1.12 Alpha with ttlSecondsAfterFinished. An example from Clean Up Finished Jobs Automatically:

apiVersion: batch/v1
kind: Job
metadata:
  name: pi-with-ttl
spec:
  ttlSecondsAfterFinished: 100
  template:
    spec:
      containers:
      - name: pi
        image: perl
        command: ["perl",  "-Mbignum=bpi", "-wle", "print bpi(2000)"]
      restartPolicy: Never
