Applications can be packaged and deployed in multiple ways using Docker. Working with Docker containers, images, and client daemon help administrators, developers, and testers quickly access updated applications and make necessary changes before production. In this course, you will learn understand the concept of Dockerization, how to work with Docker containers, Docker images, link containers, and manage data in containers.
