“It works in my machine” is a common phrase that you hear developers say when their code breaks in production. To overcome this problem, packaging the application code and its dependencies as one single deployable unit are essential, and docker has become the industry’s de facto standard to achieve this. In this course, “Developing React.js apps in Docker”, you’ll learn to dockerize a React application and learn the steps to develop, debug and deploy it in production. First, you’ll explore the different components that make up a docker file. Next, you’ll discover how to create an image and run docker container. Then, you will learn how to deploy multiple containers, setup networking between them using docker compose. Finally, you’ll learn how to debug the application inside the container and get the container production ready. When you’re finished with this course, you’ll have the skills and knowledge of developing a react application in docker needed to create a highly agile, portable, and independent microservice component.
