Docker and Kubernetes

DOWNLOAD PDF

Docker is the world’s leading software containerization platform. It packages your application into one standardised unit, wrapping it into a complete file system that contains everything needed to run on a server. Kubernetes is a system created by Google to automate the deployment, scaling and management of containerized applications (like the ones Docker creates). The two combined make life a breeze for anyone needing to transport, install and maintain complex software applications anywhere.
