Building a Docker image factory from scratch in Go (300 lines, no daemon)
Posted: Thu Jul 30, 2026 2:24 pm
Hi everyone,
I recently wrote an article about building a Docker image factory from scratch using Go. The goal was to create a minimal, OCI-compliant image builder without relying on a daemon or external cache, all in about 300 lines of standard library code.
I thought this might be interesting to the OSDev community, especially those who work with containerization or are curious about how these tools are implemented under the hood.

I'd love to hear your thoughts or any feedback you might have on the approach!
