Docker [the technology not the company] has reached a level of success where it is discussed and used by people who are not aware of the technical details of its implementation. It is entirely practical to use Docker without ever visiting Docker's official documentation.

Because Docker is an alternative to the virtual machines with which people tend to have more experience, it is normal for people to fill holes in their knowledge with facts about VM's. Much of the time, this works.

I don't think the title is great, but I think more than anything else it reflects frustration with the complexity of containers and normal disappointment with things that at first appear to be silver bullets.

The future is already here -- it's just not very evenly distributed. -- William Gibson

Author here. Apologies if this came across as clickbait. Would you point to said documentation? I haven't been able to find the parts that illuminate this issue, including on the official architecture page [1]. Thanks!
