Vagrant comes with support out of the box for using Docker as a provider. This allows for your development environments to be backed by Docker containers rather than virtual machines. Additionally, it provides for a good workflow for developing Dockerfiles.
Warning: Docker knowledge assumed. We assume that you know what Docker is and that you are comfortable with the basics of Docker. If not, we recommend starting with another provider such as VirtualBox.
