I have to deploy a Cronjob in Kubernetes that will create a Job pod every 15 minutes. The job will check if a service is ready to provide new data. Once this service is ready, the job will take more than 1 hour to complete its execution. The problem revolves around the fact that other jobs are going to be executed during this time.
In short, how can I prevent a job to be executed in Kubernetes Cronjobs when there's already a Job running?
CronJob resource has a property called concurrencyPolicy, here an example:
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: your-cron
spec:
schedule: "*/40 8-18 * * 1-6"
concurrencyPolicy: Forbid
jobTemplate:
spec:
template:
metadata:
labels:
app: your-periodic-job
spec:
containers:
- name: your_container
image: your_image
imagePullPolicy: IfNotPresent
restartPolicy: OnFailure
