Infrastructure as Code Cookbook

Using Docker with Vagrant

Development environments can often be mixed, using both virtual machines and Docker containers. While virtual machines include everything needed to run a full operating system like memory, CPU, a kernel and all required libraries, a container is much more lightweight and can share all this with its host, while keeping a good isolation through special kernel features named cgroups. Docker containers helps developers use, share and ship a bundle including everything needed to run their application. Here, we'll show how to use Vagrant to start containers. Since Docker usage is a little different between Linux hosts and other platforms, the reference used here is the native Docker platform—Linux.
