Vagrant vs. Docker

Vagrant uses kernel-level isolation whereas Docker uses userland-level isolation. In practice, this means Vagrant will provide more isolation from your virtual machines than Docker, but Docker will be faster to boot machines. After booting, speeds are roughly equivalent.

Docker also lacks support for certain operating systems (like Windows and BSD). If your target deployment is a Windows environment, Docker will not provide the same production parity as a tool like Vagrant.

Both Vagrant and Docker have a vast library of community-contributed "images" or "boxes" to choose from.
