Stop wasting resources and compromising security! 🚀 In this Docker tutorial, we reveal the pro techniques used by senior developers to build containers that are faster, smaller, and more secure. Learn the best practices that will take your Docker workflow from basic to production-ready. We'll give you a live, side-by-side comparison of container performance so you can see the massive difference these techniques make. Utilities Source Code: What You'll Learn: ✅ Master Multi-Stage Builds: Slash image size by 5x and drastically reduce CPU & memory usage. ✅ Leverage .dockerignore: Speed up builds and improve security by excluding unnecessary files. ✅ Choose & Pin Base Images: Ensure stability and security by using minimal, versioned images. ✅ Run as Non-Root User: Implement the principle of least privilege to harden your container security. ✅ Use Immutable Tags: Guarantee reproducible deployments and easy rollbacks. ✅ Enforce Resource Limits: Prevent "noisy neighbor" problems and ensure system stability. These Docker pro techniques are essential for anyone deploying applications in development, staging, or production environments.
