Flawed? sure.. useless hype?? yeah well are all the people loving it just stupid.. or is it just placebo?
The author makes a lot of conjecture with very, very little backing.
I love docker. I'm a programmer more than a systems engineer. I've used Linux as my sole computing environment for 6+ years. I've deployed countless LAMP stacks; and countable Haskell/postgres stacks.
For both having an extremely portable development/building environment; and dead-simple disbursement of binaries-with-prereqs, Docker has been INCREDIBLY useful to me.
For actual deployment of single-server apps; it might be a bit more trouble than it's worth, in some cases. I have a couple places where I develop and build in Docker; but actually deploy "raw"; because it is easier/fine.
But when you start considering Coreos clusters and docker containers to utilize them; deployment again is made congitively simpler (to us mere mortals) thinking in terms of containers.
I guess this is click-bait; but even as a passive user of Docker, I find it quite offensive; and not well-grounded.
I opened the article with an open mind; thinking someone smarter than me knew something terrible about docker that was going to bite me in the ass some day.. only to instead get the impression of, either being trolled, or that the author is my favorite type of neck-beard elitist.
