thehftguy sometimes has very good articles, but it's obvious he doesn't know/understand much about the container landscape. He would be correct if he said, "The demise of Docker swarm and rise of Kubernetes"

For those that don't know, Kubernetes is a container orchestrator. That means when you have lots of containers, hundreds or thousands and lots of servers to run them on. Instead of wiring them manually and deploying them manually, kubernetes make's it easy. kubernetes will decide which server to run them on and wire them together, if a server goes down, it will restart the down containers on new servers provided you have the capacity.

Imagine that docker is a computer program, kubernetes is the operating system.

Author here. Thank you.

The point is really about docker, not docker swarm. Kubernetes is integrating the whole ecosystem vertically and it's being leveraged to push out docker. There are lots of actors at play incentivized and actively working against docker (not just docker swarm).

I guess it's more of a business and marketing lesson if anything.
