Re: all the other things mentioned — I presume the point of Docker in that list is that the system-software packages mentioned are inside the shipped Docker image. It's an "appliance."

"Ships as a Docker image" might, for a lot of projects, just be a roundabout version of "it's a .zip file; unpack it into /opt"—but I think it's justified if your project is essentially a bunch of distro packages with a layer of policy-glue making them interoperate in a special way. Like OpenStack DevStack, or a NAS server appliance, or an "all-in-one" [L]AMP stack.

Fair enough. However, my opinion of this matter still stands. I think something like a library or even an executable/process should try to decouple itself from deployment process; and should be designed as such. Its very opinionated - I must admit - but it tends to take away a lot of friction from adopting. Also, usually, when we add things like Docker to the mix, it is quiet unclear if the said microservice can function without Docker (perhaps it's using something X specific and cannot work without it); if it can, lets mention it otherwise even if it is something I want, I won't spend the time to test it myself (yeah I am very a very picky lad I know but I bet this is something a lot of people do)

What are you talking about. Docker is a tool that positively contributes to the deployment experience and reduces friction in adoption. It is one of the tools that directly contributed to the adoption of microservices because it makes dealing with a large number of services (500+) sane and possible.

You should learn more about docker and dev-ops, because with microservices the focus is increasingly towards having developers support their services end-to-end, which means the devs are responsible for deploying/supporting the services they wrote in production.

Well its one more things to install for starters. Do I need a specific version of docker to run with this? To me it's just an extra layer of complexity.
