ob
A Job creates one or more Pods and will continue to retry execution of the Pods until a specified number of them successfully terminate.
apiVersion: batch/v1
kind: Job
metadata:
name: job
spec:
template:
containers:
– name: nginx
image: nginx:latest
command: [”/bin/sh”, “-c”, “date;”]

As pods successfully complete, the Job tracks the successful completions.
When a specified number of successful completions is reached, the task (Job) is complete.

Each of those tasks should be configured to recur indefinitely (for example: once a day / week / month).
