You are correct. cgroups v1 came from Google (mostly Paul Menage, if I recall my history). OP is in a sense slightly correct without realizing it that Borg predates cgroups themselves, but I'd wager Googlers would agree that they're pretty happily married at this point. Kubernetes just doubles down on what Borg learned in some ways (and discards others). There's a distinction between containers the concept and Linux containers, of course, but yes. You've got it right.
