I dunno man, k8s is pretty simple, but only if you make it so, I have built (early on) complicated setups with all kinds of functionality, but the complexity was rarely used. I now manage clusters and deployments on those clusters with code, terraform to be exact (tcl expect for instances when terraform can't hang yet) I built a gui interface for terraform to manage deployments of kubernetes on various clouds and bare metal and to manage the deployments To kubernetes. \n Maybe one day this will get too complex and we'll do something else but so far so good.
