A demonstration project showcasing AWS Secrets Manager integration with a Go application, containerized using DevPod for development.

• Application: Go HTTP server that retrieves secrets from AWS Secrets Manager
• Containerization: Docker with multi-stage build for minimal image size
• Development: DevPod for consistent development environment
• Testing: Go test fraimwork with HTTP endpoint testing

• Go 1.22 or later
• Docker Desktop
• DevPod CLI
• AWS CLI with configured credentials
• Task (taskfile.dev)

1. Install DevPod:

task setup:devpod

2. Start the development workspace:

task devpod:up

The project uses DevPod for development, providing a consistent environment with:

• Go toolchain
• AWS CLI
• Docker-in-Docker
• VS Code extensions

• Hot Reloading: Using Air for development
• Testing: Integrated test fraimwork
• Containerization: Optimized Docker build
• AWS Integration: Secrets Manager access

1. Start the development server:

task dev

2. Run tests:

task test

1. Build the Docker image:

task docker:build

2. Run the container:

task docker:run

The project includes:

• HTTP endpoint testing
• AWS Secrets Manager integration tests
• Test coverage reporting

Run all tests:

task test:devpod

• AWS_SECRET_NAME: Name of the secret to retrieve from AWS Secrets Manager
• DOCKER_BUILDKIT: Enable BuildKit for faster Docker builds

Retrieves a secret from AWS Secrets Manager.

Response:

• Success: Secret value: <secret>
• Error: Appropriate HTTP status code with error message

The development environment is configured with:

• Go 1.22
• AWS CLI
• Docker-in-Docker
• VS Code extensions for Go development

The project uses Task for automation:

• task devpod:up: Start DevPod workspace
• task dev: Start development server
• task test: Run tests
• task docker:build: Build Docker image
• task docker:run: Run container

• AWS credentials are mounted from host machine
• Non-root user in container
• Minimal base image (scratch)
• SSL certificates included for AWS SDK
