Convert Linux cron expressions to K8s CronJob manifests • Generate production-ready batch/v1 YAML wrappers
Format: Minute Hour Day Month Weekday
System Definition BlockQuickly convert standard Linux cron expressions into production-ready Kubernetes batch/v1 CronJob YAML manifests. Perfect for DevOps engineers.
WebToolkit Pro is engineered for zero-trust environments. This utility processes your sensitive data entirely within your browser using Web Workers.
Enter your standard cron string, desired job name, container image, and execution command. The tool validates the cron expression and dynamically interpolates your parameters into a strictly formatted, syntactically correct YAML manifest.
apiVersion: batch/v1
kind: CronJob
metadata:
name: daily-cleanup
spec:
schedule: "0 2 * * *"
concurrencyPolicy: Forbid
jobTemplate:
spec:
template:
spec:
containers:
- name: cleanup
image: alpine/curl
args: ["-X", "POST", "http://api/cleanup"]
restartPolicy: OnFailureNo. Unlike some Linux distributions or Node.js libraries that support a 6th field for 'seconds', Kubernetes strictly requires the standard 5-field format (`Minute Hour DayOfMonth Month DayOfWeek`).
The generated manifest defaults to `restartPolicy: OnFailure`, which is the best practice for CronJobs to ensure transient failures are retried without infinitely looping crashed pods.
