Stop Using Docker Like It’s 2015 (Modern Best Practices)

Docker isn’t a toy anymore. Back in 2015, we all ran docker run -it ubuntu bash, installed Vim in containers, and shipped images bloated with secrets. But it’s 2025—and those habits are holding you back. In this video, I’ll show you how to use Docker the modern way: multi-stage builds, BuildKit caching, health checks, non-root users, .dockerignore, docker compose watch, and more. Whether you’re running local dev or production workloads, stop treating Docker like it’s 2015. What you’ll learn: Why version: in docker-compose is dead (and what to do instead) Adding health checks for reliable restarts Running containers as non-root users for security Using .dockerignore to keep secrets & bloat out of your images Multi-stage builds → smaller, faster, production-ready images BuildKit + cache mounts → blazing fast builds docker compose watch for live reload in dev Why Docker is production-ready (if you configure it right) Stop blaming Docker—start using it like it’s 2025.
