Docker - A Complete Hands-On Guide - Continuous Integration (CI) with GitHub and Docker Hub

This video tutorial covers the process of setting up continuous integration (CI) using GitHub and Docker Hub. It begins with an introduction to the integration process, followed by creating repositories on both platforms. The tutorial then explains how to connect accounts and configure build settings. It also covers initializing Git, making changes to files, and troubleshooting common errors. Best practices for managing files and directories are discussed, and the video concludes with finalizing the setup and testing the CI process.
