Built with developer experience in mind, Tensorkube simplifies the process of deploying serverless GPU apps. In this guide, we will walk you through the process of deploying jina-embeddings-v2-base-code model on your private cloud. Jina-embeddings-v2-base-code is an multilingual embedding model speaks English and 30 widely used programming languages

​
Prerequisites

Before you begin, ensure you have configured Tensorkube on your AWS account. If you haven’t done that yet, follow the Getting Started guide.

​
Deploying Jina with Tensorfuse

Each tensorkube deployment requires two things - your code and your environment (as a Dockerfile). While deploying machine learning models, it is beneficial if your model is also a part of your container image. This reduces cold-start times by a significant margin. We are using the Huggingface Text Embeddings Inference toolkit to make our models utilise the full GPU capacity. You can try any of the supported model here.

​
Code files

We will use an nginx server to start our app. We will configure the /readiness endpoint to return a 200 status code. Remember that Tensorfuse uses this endpoint to check the health of your deployment. The Huggingface TEI toolkit serves embeddings at /embed and hence we configure all other endpoints to route to the TEI toolkit which is running on port 8000.
nginx.conf
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;

    worker_connections  1024;

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen 80;

        client_max_body_size 200M;

        location /readiness {
            return 200 'true';
            add_header Content-Type text/plain;
        }

        location / {
            # You may need to adjust this if your application is not running on localhost:8000
            proxy_pass http://127.0.0.1:8000;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
        }
    }
}

​
Environment files (Dockerfile)

Next, create a Dockerfile. Given below is a simple Dockerfile that you can use:
Dockerfile
# Use the Hugging Face base image
FROM ghcr.io/huggingface/text-embeddings-inference:86-1.5

# Install Python 3.10, Nginx, and other dependencies
RUN apt-get update && apt-get install -y \
    python3.10 \
    python3.10-dev \
    python3-pip \
    nginx \
    && rm -rf /var/lib/apt/lists/*

# Set Python 3.10 as the default Python version
RUN ln -s /usr/bin/python3.10 /usr/bin/python

# Upgrade pip and install the requests library
RUN pip3 install --no-cache-dir --upgrade pip && pip install requests

# Copy the Nginx configuration file
COPY nginx.conf /etc/nginx/nginx.conf

# Expose port 80 for Nginx
EXPOSE 80

# Start both Nginx and the text-embeddings-router
CMD ["sh", "-c", "nginx && text-embeddings-router --json-output --max-batch-tokens 163840 --model-id jinaai/jina-embeddings-v2-base-code --port 8000"]

​
Deploying the app

Jina is now ready to be deployed on Tensorkube. Navigate to your project root and run the following command: 
tensorkube deploy --gpus 1 --gpu-type a10g
Jina embedding model is now deployed on your AWS account. You can access your app at the URL provided in the output or using the following command: 
tensorkube list deployments
And that’s it! You have successfully deployed Jina embedding model on serverless GPUs using Tensorkube. 🚀 To test it out you can run the following command by replacing the URL with the one provided in the output: 

curl -X POST -H "Content-Type: application/json" -d '{"inputs":"&int x = &y"}' <YOUR_URL_HERE>/embed
You can also send multiple inputs in a batch. For example, 

curl <YOUR_URL_HERE>/embed \
    -X POST \
    -d '{"inputs":["Today is a nice day", "I like you"]}' \
    -H 'Content-Type: application/json'
You can also use the readiness endpoint to wake up your nodes in case you are expecting incoming traffic 
curl <YOUR_APP_URL_HERE>/readiness
