The Complete Practical Docker Guide - Running Node.js Containers

The video tutorial covers setting up and using Node.js with Docker. It begins with an introduction to Node.js and Docker, explaining how Docker can be used to run Node.js applications without installing Node.js locally. The tutorial then guides viewers through pulling a Node.js image from Docker Hub, running it in interactive mode, and executing JavaScript commands. Finally, it demonstrates creating and running a simple Node.js application within a Docker container.
