Building a Hybrid Docker Orchestrator in Go: The Journey from Single VM to Multi-Node Cluster

Short summary

A developer shares the journey of building Gubernator (gbnt), a Go-based container orchestrator positioned between Docker Compose and Kubernetes. The project features decentralized DNS via CoreDNS, local ingress via Caddy, and SQLite-based state management. 100% of the code was co-authored with Antigravity, Google DeepMind's agentic AI pair programmer, which handled debugging complex network behaviors and infrastructure bootstrapping.
