Automatically delete completed Jobs.
In some cases, you cannot customize the kubernetes's component arguments. So it's impossible to support the job's ttlSecondsAfterFinished feature by add --feature-gates=TTLAfterFinished=true to controller, apiserver, scheduler arguments list.
And so it's come.
You just need to add a annotations(kube-job-cleaner/ttlSecondsAfterFinished) in the job. For example,
apiVersion: batch/v1
kind: Job
metadata:
name: pi
annotations:
kube-job-cleaner/ttlSecondsAfterFinished: "30"
spec:
template:
spec:
containers:
- name: pi
image: perl
command: ["perl", "-Mbignum=bpi", "-wle", "print bpi(2000)"]
restartPolicy: NeverThis is a example in kubernets cluster. Also you can deploy out of cluster.
