Unfortunately I don't have a good blog article about this.

I actually thought it would be good to write a k8s blog article After Reading this blog.

If you can, click yourself a small cluster in one of the big cloud providers.

Alternativly I think Google has some k8s colabs were you can try it out.

Setting up a small application yourself or looking into what helm charts exist might help .

Like the helm charts for known open source projects like PostgreSQL from bitnami.
