Quoting from the disadvantages section: "Second, Kubernetes excels at automatically fixing problems. But it’s so good at it that containers can crash and be restarted so fast you don’t notice your containers are crashing. "
A key part of Kubernetes is to the bring the state of the system to that of the spec, through a series of watches - and in some places polling (config maps watching in kubectl as of 1.4.x) - this may look like magic, but it's not fixing problems per se its that your desired state of the system (the spec) is different to what is observed (the status). This is not a disadvantage. Kubernetes if not for someone sitting at the terminal expecting a bell or stop the world when problems happens, although I guess you could configure it that way and fight against the system.
