Learn Docker - DevOps with Node.js & Express - Transcript [EN]

The video walks through building a Node.js and Express app inside Docker, starting from a simple Express server to creating a custom Docker image, then running and debugging containers. It covers Docker basics like Dockerfiles, images, containers, port mapping, and environment variables, and introduces development workflows using bind mounts, nodemon, and Docker volumes. It then expands to Docker Compose for multi-container setups, including a MongoDB database, and discusses production considerations with separate dev and prod configurations. The tutorial emphasizes practical tips for speeding development with caching, volumes, and environment management, and ends with more advanced topics like production builds and data persistence.
