A Comprehensive Tutorial on Deploying a Scalable Machine Learning Service on Kubernetes
Overview of the Tutorial
This tutorial covers the entire pipeline of deploying a Sentiment Analysis model — from model development to scalable, monitored production deployment on Kubernetes.
Here’s a glimpse of what you will build and learn:
- Sentiment Analysis Model developed with Scikit-Learn for natural language processing tasks.
- A FastAPI-based REST API serving the model, enabling easy, low-latency inference.
- Containerization using Docker or Podman to package the application and dependencies.
- Kubernetes Deployment, including setup of clusters, persistent storage for model artifacts, and auto-scaling using the Horizontal Pod Autoscaler (HPA).
- Real-time monitoring using Prometheus to track application health and performance metrics.
This project equips you with practical MLOps skills to deploy and maintain machine learning applications at scale.
What You’ll Learn
- Building and training a sentiment analysis model with Scikit-Learn.
- Designing a RESTful API using FastAPI for seamless model inference.
- Containerizing ML services with Docker or Podman for portability.
- Creating and managing Kubernetes clusters with Kind (Kubernetes in Docker).
- Configuring Persistent Volumes (PV) and Persistent Volume Claims (PVC) for reliable storage.
- Managing application configurations with Kubernetes ConfigMaps.
- Implementing Horizontal Pod Autoscaling (HPA) for dynamic load management.
- Setting up Prometheus monitoring for real-time insights and alerts.
- Testing APIs and Prometheus metrics along with common debugging practices.
