"If you expect anything positive from Docker, or its maintainers, then you're shit outta luck.[..]If your development workflow is sane, then you will already understand that Docker is unnecessary[..]Docker would have been a cute idea 8 years ago, but it's pretty much useless today"

Umm ok? Judgement, jumping to conclusions. Take out some of that kind of tone and you have some legitimate criticisms of docker that might be taken more seriously.

There are some real warts in the docker core & community, and a high barrier of entry for multi-node deployments and isolated networks, but on the flipside, deterministic image build & deployment is a big win compared to many other ways of doing this stuff (at scale).

IMO, one of the biggest positives that Docker-like provisioning encourages is clustered-by-default architectures. When you build around failure by assuming nodes come and go (as easily as Docker makes it) your platform availability is likely to be more resilient to some types of failure.
