Hello World App Deployment on AWS ECS with Fargate using Terraform and GitHub Actions

This guide walks you through the process of deploying a simple "Hello World" Node.js application on AWS ECS (Elastic Container Service) with Fargate using Terraform for infrastructure provisioning and GitHub Actions for Continuous Deployment.

1. Node.js Application

Create a simple "Hello World" Node.js application.

app/index.js

const express = require('express');
const app = express();

app.get('/', (req, res) => {
  res.send('Hello, World!');
});

const port = process.env.PORT || 3000;
app.listen(port, () => {
  console.log(`App running on port ${port}`);
});

2. Dockerfile

Create a Dockerfile to containerize the Node.js application.

Dockerfile

FROM node:14

# Create app directory
WORKDIR /usr/src/app

# Install app dependencies
COPY package*.json ./
RUN npm install

# Bundle app source
COPY . .

# Expose port
EXPOSE 3000

# Run the application
CMD [ "node", "app/index.js" ]

3. Terraform Configuration

Define the Terraform configuration to set up AWS infrastructure.

terraform/variables.tf

[...]

terraform/main.tf

[...]

terraform/terraform.tfvars

[...]

terraform/outputs.tf

[...]

4. GitHub Actions Workflow

Set up the GitHub Actions workflow to automate deployment.

.github/workflows/deploy.yml

[...]

5. GitHub Secrets

Configure necessary secrets in your GitHub repository.

Execution Steps

1. Initialize Terraform:

   cd terraform
   terraform init

2. Apply Terraform Configuration:

   terraform apply -var "docker_image=<YOUR_DOCKER_IMAGE_URL>"

3. Commit and Push Code to GitHub:

   git add .
   git commit -m "Initial commit"
   git push origin main

Upon pushing to the main branch, GitHub Actions will trigger, building and deploying your Node.js app to AWS ECS Fargate.

This setup ensures a fully automated pipeline for deploying a "Hello World" Node.js application using Terraform and GitHub Actions on AWS ECS with Fargate.
