Tired of chasing the "perfect" container? You've tried distroless for security, scratch for minimalism, Alpine for size, and multi-stage Dockerfiles to trim layers - only to end up wrestling hidden dependencies, drifting tags, and surprise CVEs. Let's leave that behind.
In this 10-minute demo, I'll show you how to transform your CI pipeline with Nix flakes so every build yields a minimal, secure, immutable golden image:
1. Flake-driven CI
Replace your sprawling Dockerfile with a single flake.nix that declaratively pins every OS package, runtime, and library.
2. Automagic minimalism
Nix's purity model pulls only what you need, producing images measured in megabytes, not gigabytes
3. Hermetic dev and CI parity
Leverag nix develop for a dev shell identical to your CI build environment. Say goodbye to "it works on my machine".
Step into the light and and say goodbye to your Dockerfile nightmares.
