docker

Before we dive into some of the highlights from DockerCon 2017, let’s do a quick overview of what Docker is. Quite simply, a “docker container” is a portable container, of sorts, that allows a collection of apps to run on any operating system. How is it possible, you ask, for a docker container to allow any app to “Build, Ship and Run,” as the docker motto says, on any OS? A docker container uses kernel features to produce resource isolation (CPU, memory, block I/O and more) as well as separate namespaces, to isolate the application’s view of the operating system (a visual depiction below).
