Getting started with docker
Docker is a popular way of packaging your applications, or micro services into container images, which can be copied to any running docker server. Docker uses a linux kernel feature - namespacing - which allows it to run applications in isolation away from the operating system, much like virtual machines, avoiding common pitfalls of virtualization like CPU and RAM allocation. Each docker container is much like any standalone application, except for the fact that it’s isolated away from the host OS.
