Docker Image

A docker image is a self-contained, layered archive containing an application and all of its OS dependancies and is the artifact of running a docker build. The image is what gets stored in a docker registry.


A Dockerfile is a lightweight DSL that contains all the commands a user could call on the command line to assemble an image in order to run an application.


Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes builds upon 15 years of experience of running production workloads at Google, combined with best-of-breed ideas and practices from the community.
