Deep dives into resilient infrastructure, CI/CD automation, and the engineering decisions that keep production systems alive.
Docker: From Zero to Production · Part 676% of Docker Hub images have known vulnerabilities. Here's how to close the gaps attackers actually exploit - root containers, leaked secrets, wide-open capabilities, and frozen base images.
Docker: From Zero to Production · Part 5Understand exactly what Docker Compose does under the hood, how depends_on actually works, and the secrets of production-ready yaml setups.
Docker: From Zero to Production · Part 4You set up a firewall rule to block a port. Docker quietly ignores it. Here's why.
Docker: From Zero to Production · Part 3One Dockerfile ordering mistake is silently wasting hours of your week. A deep dive into how Docker image layers work, how the build cache thinks, and why multi-stage builds can shrink a 1GB image down to 12MB.
Docker: From Zero to Production · Part 2Spoiler: it's not magic. It's three Linux kernel features that took 11 years to build. A deep dive into namespaces, cgroups, OverlayFS, and the hidden call chain behind 'docker run'.
Docker: From Zero to Production · Part 1The tool that changed how we ship software - born from a 5-minute talk that got cut off. The story of the 'works on my machine' problem, why VMs couldn't fully solve it, and the kernel-sharing insight that made containers click.
Seven articles that take you from 'why does Docker exist' to running a real CI/CD pipeline with multi-arch builds. Each one standalone, but they build on each other — the series most Docker tutorials never write.
