🚀 FastAPI SageMaker Integration

📖 Overview

This application is a simple FastAPI web service that integrates with AWS SageMaker for predictions. It's designed to fetch environment variables for AWS authentication and invoke a specific SageMaker endpoint to get predictions.

✨ Features:

1. 1.🙌 Welcome Route: Accessing the root URL (/) provides a welcome message indicating the service is up and running.

1. 1.🔍 Environment Variables Check: The /check-env-vars/ route allows for a quick check on the AWS environment variables. It shows if the AWS_ACCESS_KEY_ID and ENDPOINT_NAME have been set up correctly while keeping the AWS_SECRET_ACCESS_KEY hidden for security purposes.

1. 1.🔮 Prediction Route: The /predict/ route enables you to make prediction requests to a pre-configured SageMaker endpoint. The app interfaces with the SageMaker runtime using the provided AWS credentials, and forwards the user's input for predictions.

⚙️ Setup:

📡 Get SageMaker Endpoints

To obtain the list of SageMaker endpoints:

aws sagemaker list-endpoints --region your-region-name

🌍 Export Your Environment Variables

Set up the required environment variables:

export AWS_ACCESS_KEY_ID='YOUR_AWS_ACCESS_KEY_ID'
export AWS_SECRET_ACCESS_KEY='YOUR_SECRET_KEY'
export ENDPOINT_NAME='YOUR_ENDPOINT_NAME'

🏃 Running the FastAPI Application:

You can start the FastAPI application using the following:

uvicorn app:app --reload
uvicorn app:app --reload --port 8080

Or simply run:

python app.py

If you're using AWS Cloud9, view the running FastAPI app by navigating to: Tools > Preview Running Applications.

🔗 Testing the Endpoints:

• —🌐 Using a Web Browser: For GET requests, simply open a web browser and navigate to the endpoint URL (e.g., http://localhost:8000/predict/). However, our prediction endpoint requires a POST request.

• —🔧 Using curl: To make a POST request, use the following curl command:

curl -X POST "http://localhost:8000/predict/" -H "accept: application/json" -H "Content-Type: application/json" -d "{\"data\":\"YourDataHere\"}"

🛠️ Using Git inside Cloud9:

Set your Git configuration if prompted:

git config --global user.name "Your Name"
git config --global user.email you@example.com

To fix the identity for a specific commit:

git commit --amend --reset-author
