Doubt regarding the CronJob about kubernetes HOT 3 CLOSED

Yes, cronjobs in Kubernetes aren't exactly like cronjobs on a server. I'm thinking you might need to read up on sidecar containers. But having never used them myself, that's as far as my recommendation goes.

My tool of choice in Linux is a BASH script so I tend to tackle all manner of problems in kubernetes with scripts. To that end, I'd get the Dockerfile used to build Matomo and add a script just before going to the Entrypoint. Say you want to run a cleanup process every hour, I'd do this:

CMD [ "while true; do cleanup; sleep 3600; done" ]

NOTE: This is untested code but I hope you get the gist.

@ak2766 Thank you for your reply. It really helped me to get closer to the answer. I used command: [] (i.e. CMD [] as you mentioned) in my CRON job to get it done.

I also got to know that we cannot create a cron job for a running pod. But we can reuse the PVC used by the running pod by setting a POD AFFINITY rule in the CRON JOB which matches the label of the same pod.

@ak2766 thanks for helping.
