Serverless CI/CD pipelines via Lambda & GitHub Actions
Why Choose This Project
-
Traditional CI/CD pipelines often require maintaining build servers and runners, which increases cost and complexity.
-
Serverless CI/CD eliminates infrastructure overhead by using AWS Lambda for pipeline execution and GitHub Actions for orchestration.
-
It provides a cost-efficient, scalable, and automated deployment pipeline ideal for cloud-native applications.
What You Get
-
A serverless CI/CD pipeline that integrates GitHub Actions, AWS Lambda, and AWS services (CodeBuild/CodeDeploy/S3/ECS/EKS).
-
Automatic build, test, and deployment on code pushes or pull requests.
-
Real-time monitoring of pipeline execution using AWS CloudWatch.
Key Features
| Feature | Description |
|---|---|
| GitHub Actions Integration | Triggers build & deployment workflows automatically when code is pushed. |
| Serverless Execution | Uses AWS Lambda for build/deploy steps instead of dedicated CI servers. |
| Multi-Environment Deployments | Supports dev, staging, and production pipelines. |
| Automated Testing | Runs unit/integration tests as part of the pipeline. |
| Cost Optimization | Pay-per-use model since Lambda runs only when triggered. |
| Notifications | Pipeline success/failure alerts via Amazon SNS/Slack/Email. |
Technology Stack
Frontend/Client
-
GitHub Repository (source code)
-
GitHub Actions Workflows
Backend / Serverless Pipeline
-
AWS Lambda – Executes CI/CD tasks
-
AWS CodeBuild – For build & testing
-
AWS CodeDeploy / ECS / EKS – For deployment
Storage & Artifact Management
-
Amazon S3 – Stores build artifacts
-
Amazon ECR – For container images (if Docker-based apps)

Workflow
-
Code Push to GitHub
-
Developer commits code → GitHub Actions workflow triggers.
-
-
GitHub Actions Workflow
-
Workflow sends event payload to AWS Lambda.
-
-
Build & Test Phase
-
Lambda invokes AWS CodeBuild for compiling code & running tests.
-
-
Artifact Storage
-
Build artifacts pushed to S3 or ECR (for Docker images).
-
-
Deployment Phase
-
Lambda triggers CodeDeploy, ECS, or EKS for application deployment.
-
-
Monitoring & Notifications
-
Logs sent to CloudWatch.
-
Alerts via SNS/Slack on success/failure.
-
Main Modules
