How to Integrate Hugging Face with Kubernetes

Set Up Your Environment

• Ensure you have a Kubernetes cluster running. You can use Minikube for local development or any cloud provider's Kubernetes service for deployment.

 

• Install the necessary CLI tools: kubectl for managing Kubernetes clusters and the Hugging Face CLI for interacting with Hugging Face services.

# Install kubectl
brew install kubectl

# Install Hugging Face CLI
pip install huggingface_hub

Create a Hugging Face Model API

• Sign up for a Hugging Face account and navigate to the Hub. Select a model you want to run.

 

• Create an API token from your Hugging Face account settings and save it securely. You'll need it for accessing the Hugging Face model from your Kubernetes deployment.

Containerize Your Application

• Create a Dockerfile for your application. This file should contain instructions to set up the environment and run your application.

 

• Ensure to install necessary libraries and copy your codebase into the Docker image.

FROM python:3.8-slim

WORKDIR /app

COPY . /app

RUN pip install -r requirements.txt

ENTRYPOINT ["python", "app.py"]

Push Docker Image to a Registry

• Build the Docker image and tag it appropriately.

 

• Push the Docker image to a container registry like Docker Hub or Google Container Registry.

# Build the Docker image
docker build -t username/hf-kubernetes-example:latest .

# Push the Docker image 
docker push username/hf-kubernetes-example:latest

Deploying to Kubernetes

• Create a Kubernetes deployment manifest. This YAML file should include specifications for your app's deployment, such as image location and replication settings.

 

• Apply the deployment manifest to your Kubernetes cluster.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hf-kubernetes-example
spec:
  replicas: 2
  selector:
    matchLabels:
      app: hf-kubernetes-example
  template:
    metadata:
      labels:
        app: hf-kubernetes-example
    spec:
      containers:
      - name: hf-kubernetes-example
        image: username/hf-kubernetes-example:latest
        ports:
        - containerPort: 80
        env:
        - name: HF_API_TOKEN
          valueFrom:
            secretKeyRef:
              name: hf-secret
              key: api-token

Expose Your Application

• Create a Service to expose your application. Use a LoadBalancer if you want external access.

 

• Apply the Service manifest to your Kubernetes cluster.

apiVersion: v1
kind: Service
metadata:
  name: hf-kubernetes-service
spec:
  type: LoadBalancer
  ports:
  - port: 80
  selector:
    app: hf-kubernetes-example

Secure Your Deployment

• Create secrets for sensitive information like API tokens using Kubernetes secrets.

 

• Ensure your application can retrieve these secrets and use them safely.

kubectl create secret generic hf-secret --from-literal=api-token=your_hf_api_token_here

Monitor and Troubleshoot

• Use `kubectl get pods` to check the status of your pods and ensure they're running.

 

• Use `kubectl logs pod_name` to view logs and troubleshoot any issues in your deployment.

# Check the status of all running pods
kubectl get pods

# View detailed logs of a specific pod
kubectl logs <pod_name>
