batch/v1beta1 CronJob is deprecated in v1.21+

[tommady]

Hi,
I am using the kubegres for a while in the EKS k8s v1.21 cluster and my log keeps showing the below message

batch/v1beta1 CronJob is deprecated in v1.21+, unavailable in v1.25+; use batch/v1 CronJob

I am not sure if it needed to be fixed right now, but I'd be glad to upgrade it.

I tried to create a PR,
(yet but following the contribution guide I have to open an issue first)

so here I am.
please guide me if I was doing anything wrong 🙇🏻
Thanks!

@tommady , that's just a warning, and such warnings are quite popular when things are deprecated.

Remember, people still run older version of k8s, for example, a cluster could be on say, v1.18 and if we try to use batch/v1 (instead of batch/v1beta1) on such a cluster, it might fail.

Applying this upgrade means that a minimum k8s version of 1.21. is needed. In the end it will be up to the maintainers to decide.

I think it might be better to update the readme with the supported k8s versions for each release.

Oh yes you are right.
Sorry for the bothering.

I'm sorry to comment this issue but Kubernetes 1.25 is out now, it means Kubegres can't work anymore if a cluster is upgraded to the latest version. It can prevent some people to upgrade their cluster(s).

Maybe this issue should be re-opened? At least a warning on the README.md would be nice.
