Containers 101

Container technology is a way to create a virtual environment by using an isolated process on a host computer. The isolated process, the container, has its own set of file system resources and subordinate processes. And, the container does not intrude on the host system, nor does the host system intrude on the container.

A container runs on the kernel of the host computer (see Figure 1). A component called, a container manager, makes it so that the container can run on the host.
