What is Docker?
Docker is an open-source platform that uses developing, shipping and running containers. Docker’s workflow makes development, testing, and deployment much easier and much faster. Docker for real-world applications and gain hands-on experience with, deploying and managing market-leading cloud platforms, you must be familiar with the basic concepts of Docker. Docker is the world’s leading software containerization platform. It packages your application into one standardized unit, wrapping it into a complete file system that contains everything needed to run on a server.
Docker Containers help to improve Software development, Application development, and business agility. Docker container starts with a Dockerfile. A Dockerfile is a text file written in an easy-to-understand syntax that includes the instructions to build a Docker image (more on that in a moment). Docker Containers provide a highly efficient and highly granular mechanism for combining software components into the kinds of application and service stacks needed in a modern enterprise, and for keeping those software components updated and maintained.
