How to get logs of jobs created by a cronjob?
From documentation of CronJobs and Jobs
A Cron Job creates Jobs on a time-based schedule
...
A job creates one or more pods and ensures that a specified number of them successfully terminate.
All you need is to view logs for a pod that was created for the job.
Find your job with
kubectl get jobs. This will return your CronJob name with a timestampFind pod for executed job
kubectl get pods -l job-name=your-job-@timestampUse
kubectl logs your-job-@timestamp-idto view logs
Here's an example of bash script that does all the above and outputs logs for every job's pod.
jobs=( $(kubectl get jobs --no-headers -o custom-columns=":metadata.name") )for job in "${jobs[@]}"do pod=$(kubectl get pods -l job-name=$job --no-headers -o custom-columns=":metadata.name") kubectl logs $poddone
