Docker & Orchestration Engineering Skill

This skill guides AI agents and engineers to build, standardize, and maintain containerized software environments following the Zero Host Dependencies philosophy:

🛡️ Zero Host Dependencies Invariant:
The host machine requires only Docker (with Compose) and GNU Make.
All runtimes (Bun, Node, PHP, Go, Python), package managers, linters, test runners, and database CLIs MUST execute inside isolated, ephemeral containers.

🧭 Core Architectural Pillars

[ Makefile Orchestrator ] ➔ [ Split Compose Layer ] ➔ [ Multi-Stage Container ]
       (make <target>)         (base vs .dev.yml)        (deps ➔ test ➔ distroless)
