This is a silly article really. If a company looks for a specific skill set like Docker or Kubernetes, I think the company is hiring people who would become irrelevant after 5 years because you never know what newfangled orchestration tools would be the "right way to do it" then. Fortunately, companies do not hire in a silly way like this. Sure they write "Kubernetes" as one of the many things in their job descriptions but all companies I have interviewed with would be equally okay to hire someone who demonstrates strong Docker skills or strong sysadmin skills or even strong OS skills.

These skills are transferrable from one implementation to another. It makes no sense in this age to put all our eggs in one Kubernetes basket to be hireable. Expertise of the underlying computer science and engineering is far more important.
