Here's another Tidbit, that I had half forgotten - Docker wasn't Kubernetes native platform. https://youtu.be/YrxnVKZeqK8?t=598 - Google originally was going to launch k8s far more borg-like, using https://github.com/google/lmctfy as the container engine. LMCTFY is the most direct part of Borg released to the outside world. It is the container engine of the Borglet (analogous to the Kubelet) ripped out fairly directly.
