Is it possible for me to upgrade the Kubernetes that comes with Docker Mac? I just downloaded it from Docker Hub today, and the bundled version of Kubernetes is 1.10.11.
No, not really, at least, not as part of the product. The kubernetes orchestrator is baked into the package, and to my knowledge, it not upgradeable in-place within the product itself. Later, more recent versions of docker desktop and docker desktop enterprise will have more recent versions of kubernetes included, often with custom or cherry-picked fixes and security updates backported from later versions of the mainline kubernetes distribution.
For what it’s worth, I have a similar question related to
