"You mean I can push code to GitHub and AWS will auto-deploy it?!"
Yes. You can. And itโs easier than you think.
In this post, Iโll walk you through building a complete CI/CD pipeline on AWS using CodePipeline + GitHub โ step by step, with simple language, real-life analogies, and practical code snippets.
Whether youโre deploying a static site, Node.js app, or Docker container, this guide will help you go from zero to auto-deploy hero in under 20 minutes.
Letโs roll! ๐ฏ
๐ง What is CI/CD (in Human Language)?
CI/CD = Continuous Integration + Continuous Deployment
- CI: Every time you push code, it's tested and packaged automatically
- CD: That packaged code gets deployed to your server โ no more manual copy-pasting!
Think of it like setting up a robot that listens to GitHub and launches your app every time you update it.
๐ ๏ธ Tools Youโll Use
Tool | Purpose |
---|---|
GitHub | Where your source code lives |
CodePipeline | Orchestrates the CI/CD process |
CodeBuild | Optional: Builds, tests, or packages your app |
S3 / EC2 / Lambda / ECS | Final deployment destination |
๐งฐ Prerequisites
- A GitHub repo with your app (even a basic HTML file will work)
- AWS account with permissions to use CodePipeline, CodeBuild, S3, EC2, etc.
- Basic knowledge of Git
๐ฆ Step-by-Step: Create Your First AWS CI/CD Pipeline
Step 1: Connect GitHub to AWS
- Go to AWS Console โ CodePipeline
- Click Create pipeline
- Name your pipeline (e.g.,
my-awesome-pipeline
) - In Source, choose:
- Provider:
GitHub (version 2)
- Connect your GitHub account
- Choose your repo + branch
Step 2: Add a Build Stage (Optional)
If you need to compile or test your code:
- Add a Build stage using AWS CodeBuild
- Provide a
buildspec.yml
file in your repo:
version: 0.2
phases:
build:
commands:
- echo "Building..."
- npm install
- npm run build
artifacts:
files:
- '**/*'
If you're just deploying static files, you can skip this step.
Step 3: Add Deploy Stage
Choose where to deploy:
- S3 (for static websites)
- EC2 (via CodeDeploy)
- ECS / Lambda for containers or serverless
๐ฆ Example: Deploy to S3
- Create an S3 bucket
- In the Deploy stage, choose "Amazon S3"
- Provide the bucket name
- AWS will upload your build artifacts automatically
๐ Done! Push code to GitHub โ Pipeline triggers โ S3 gets updated
๐ Real-Life Example: Deploying a React App to S3
- Add this
buildspec.yml
to your React repo:
version: 0.2
phases:
install:
commands:
- npm install
build:
commands:
- npm run build
artifacts:
base-directory: build
files:
- '**/*'
- Build stage runs
npm run build
and prepares files - Deploy stage pushes the
/build
folder to S3
Push to GitHub and watch the magic happen ๐ฎ
๐ง Why Use CodePipeline?
- โ Fully managed, no servers to maintain
- โ Pay-as-you-go pricing
- โ Deep integration with AWS services
- โ Easy rollback, logs, and versioning
And best of all โ no more "it works on my machine" excuses ๐ป๐ฅ
โ ๏ธ CI/CD Best Practices
- โ Use separate pipelines for staging & production
- โ Add tests in the build phase
- โ Use IAM roles โ never hardcode AWS keys
- โ Enable notifications with SNS or Slack
๐ Final Thoughts + Bonus Tip
CI/CD isnโt just a buzzword โ itโs how modern devs ship fast and ship safe. With GitHub + AWS CodePipeline, you can automate your deployments like a pro.
๐ก Bonus: Use GitHub Webhooks + AWS Lambda for ultra-custom workflows.
