Honestly? Pretty fucking awesome if you get it configured correctly. I don't think it's super useful for production (I prefer chef/vagrant) but for dev boxes it's incredible at producing consistent environments even on different OSes and architectures.

Anything that makes it less painful for a dev to destroy and rebuild an environment that's corrupt or even just a bit spooky pays for itself almost immediately.

Yeah!

Docker and OCI get abused a lot to thoughtlessly ship a copy of the developer's laptop into production.

Life is so much simpler after taking the time to build thoughtful correct recipes in an orchestration tool.

Exactly. The learning curve is mean, but it's worth it quickly as soon as the first mystery bug dies in a rebuild fire.
