I'm not particularly fond of Docker but I don't see it going away any time soon. I acknowledge there has been alternatives around which were better in some aspects than Docker yet haven't worked in a single company that didn't use Docker with Kubernetes or other orchestrators (e.g. AWS ECS). Not saying they don't exist, but it's very rare on my experience (both as fte and as a consultant).

Also I have never met a dedicated "docker expert" as the article calls it. I mean, is there any company out there who's hiring people that only knows Docker? Does that make any sense?

Docker may get replaced by alternatives as they start getting more traction over time but I don't think this will happen all of the sudden - Docker is still relevant for good or for bad.

It would be worrying if something as basic as Docker required an expert's worth of arcane procedures, workarounds, tricks, ancillary tools and so on.

In my experience Docker is almost as trouble-free as it should be, with straightforward tools to make mistakes and undo them; it requires good engineers who know what they want, not wizards who know how to get it.
