I haven't used k8s in quite a few years, what would you recommend I look at these days to get a good overview and understand all the different pieces in the ecosystem?
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.
