Deploy Any Node.js App to Render with Docker and GitHub Actions in Minutes

This is your complete, copy-paste-ready guide to set up automated deployment for any Node.js application. Whether you're building a REST API, web app, or micro-service system, this tutorial will get you from zero to production deployment in under 30 minutes.

What You'll Build

✅ Universal Node.js app - works with any framework (Express, Fastify, NestJS, etc.)

✅ Docker containerization - consistent deployment across environments

✅ GitHub Actions CI/CD - automated testing, building, and deployment

✅ Render cloud deployment - production-ready hosting with automatic scaling

✅ Zero-downtime deployments - blue-green deployment with health checks

Project Structure

If you don't have a Node.js project at hand, you can use this repository to follow the steps in this tutorial.

Complete Deployment Guide

Step 1: Copy the Required Files

1. In your repository, create `.github/workflows/three-stage.yml` with the following structure. You can copy the config from this link.

   
   

After you run the command, you will be able to see this in your working directory.

This is the content of the `three-stage.yml`:

Step 2: Create Dockerfile

Step 3: Customize Your Configuration

Change these 3 values only:

1. App Port: Update `APP_PORT` in `deploy.yml` (default: 10000)

2. App Name: Update `DOCKER_IMAGE` in `deploy.yml` (e.g., "my-node-app")

3. Health Check: Update `HEALTH_CHECK_PATH` in `deploy.yml` (default: "/health")

   
   

Step 4: Set Up Render Deploy Hook

A deploy hook lets you trigger deployments securely from GitHub Actions.

1. On the left menu bar on your Render project page, choose Settings.

2. Copy the URL under Deploy Hook.

3. On your GitHub repository, go to → Settings → Secrets and Variables → Actions.

   
   

1. Click on New repository secret.

   
   

1. Use `RENDER_DEPLOY_HOOK` as the secret's name and the copied URL as the secret's value. Click on Add secret!

   
   

Step 5: Commit and Push Your Changes

1. Commit and push your changes:

   
   

Step 6: Monitor Deployment

1. Check the GitHub Actions tab for build progress.

2. View the Render dashboard for deployment status.

3. Test your deployed app at your Render URL.
