The Complete Practical Docker Guide - Building Docker Image for the Frontend App

The video tutorial explains the process of building a custom Docker image for a front-end application. It covers the six steps involved in the build process, including copying files, running commands, and optimizing the rebuild process using cached layers. The tutorial demonstrates how to prepare for the Docker build by removing the node_modules folder and executing the build command. It also details the steps Docker takes during the build, such as pulling the node image, installing dependencies, and exporting the final image. Finally, the video shows how to tag the Docker image for easy identification and use.
