Learn Docker - DevOps with Node.js & Express

Master Docker fundamentals through a hands-on course building a Node.js and Express application with MongoDB and Redis databases. Begin with a single container setup, progressively increasing complexity by integrating MongoDB and Redis for authentication. Learn CLI operations before transitioning to Docker Compose, addressing the challenges of moving from development to production environments. Deploy an Ubuntu VM as a production server and utilize Docker Swarm for container orchestration and rolling updates. Cover topics including custom Dockerfiles, image layers, caching, networking, bind mounts, environment variables, CRUD operations, authentication, load balancing with Nginx, and automating deployments. Gain practical experience in DevOps practices and container management throughout the comprehensive 5-hour tutorial.
