Build a Full CI/CD Pipeline for a Node.js App: From Zero to Auto-Deploy in One Hour

Description and use

An automated CI/CD workflow for a Node.js app that runs tests, builds a Docker image, pushes to GHCR, and deploys to Fly.io on every push.

Problem

Deploying code manually via SSH and git pull is error‑prone and slow.

Outcome

Automated pipeline reduces deployment time to seconds, eliminates manual steps, and ensures consistent environment via Docker.

Workflow

• Create minimal Node.js app with Express and tests
• Add Jest/Supertest test for root endpoint
• Write Dockerfile and .dockerignore
• Configure GitHub Actions workflow YAML to run tests, build image, push to GHCR, and deploy to Fly.io
• Commit and push to GitHub
• Observe pipeline run and live URL

Evidence

Push your code to GitHub, watch it test itself, build a Docker image, and deploy to a live URL automatically.

Source

A single git push will trigger a pipeline that runs your tests, builds a Docker image, pushes it to a registry, and deploys your app to a live URL with zero manual steps.
