DevOps Engineering

Purpose

DevOps solves the "works on my machine" problem by codifying the build, test, and deploy process into a repeatable, automated pipeline. For vibe-coders, this is often the last step they think about and the first step that breaks in production. This skill builds the deployment pipeline alongside the application, not after.

SOP: CI/CD and Containerization

Step 1 - Stack Discovery

Before applying any templates, ask:

"What's your hosting provider? (e.g., Vercel, Railway, AWS ECS, GCP Cloud Run, Fly.io) And where is your repository? (GitHub, GitLab, Bitbucket)"

The CI/CD platform and Dockerfile structure depend on these choices. Most Next.js frontends go to Vercel (no Dockerfile needed). FastAPI backends go to Railway, Fly.io, or a container registry.

Step 2 - Dockerfile (FastAPI Backend)

Use a multi-stage build to keep the production image small:
