Another good point is that Docker's layered filesystem allows for caching that greatly benefits the use case you're describing. We have an old .net app we pushed to servers via zip files, and the sheer size of the zip ended up being a burden after many deployments. Docker's caching and "docker prune" make things a lot easier.
