Introduction to Docker and Containers

Overview

Docker containers have become the most common part of the process of packaging up and deploying applications. Large-scale technology giants such as Amazon, Google, and Microsoft rely on them so developers need to understand how to use containers. A Docker container is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings. Docker streamlines the development lifecycle by allowing developers to work in standardized environments using local containers which provide your applications and services. Containers are great for continuous integration and continuous delivery (CI/CD) workflows. In this course, Noureddin introduces Docker and containerization technology, why it is useful, and what the clear benefits are. He covers how to install Docker, how to run containers successfully, and how to professionally containerize applications with Dockerfile. This course offers a glimpse into real-world applications to show how the containerization and deployment process work.
