K8s took a few months to learn well enough to migrate my companies production services, and most of that was Istio. K8s simplifies things and makes life easier. It's just different from traditional Sysadmin methods. Drupal's Organic Groups by itself is way more complex than K8s. I've played guitar for 35 years and really am not very good. Maybe you should pick up a hobby that is actually difficult to "re-calibrate" your scale.
unpopular opinion.<p>The core issue is that Linux userland is a complete utter f*kin mess, and these apps that run on it, cant even depend on the correct libc being installed.<p>The root reason is the linux kernel refuses to fix EVEN known kernel bugs in that it will "break" userland. This is a policy that has been proven to be a serious error, however it takes a long time to show why its an error.<p>Docker & k8s would not be needed if the userland was done right. Fixed at both the kernel and user application level. FreeBSD has jails, but its not even the same in purpose and ablities.<p>Kubernetes is complex, even google says that now. The real fix to these issues that the linux kernel and userland will need to be engineered, not shattered in 1000 pieces. Will this happen ? no, not with redhat and linus. Thus, in the next 5 years there will be a rise of BSD or a fork of linux, that will end the current rule of linus.
