Streamline AI Model Deployment with Docker Model Runner: A Developer's Guide

Are you looking for a streamlined way to deploy and manage AI models? Docker Model Runner offers a powerful solution for running models within Docker containers, simplifying development and deployment workflows. This guide provides an in-depth look at using Docker Model Runner, enhancing your AI development process.

What is Docker Model Runner?

Docker Model Runner is a backend library designed to work with Docker Desktop. It allows you to manage and interact with AI models directly from your Docker environment, treating models like containerized applications. This approach fosters both flexibility and consistency across different environments.

Currently under rapid development, Docker Model Runner is evolving quickly, so keep an eye on updates. Its goal is to provide a seamless experience for integrating AI models into your Docker workflows.

Key Benefits of Using Docker Model Runner

• Simplified Deployment: Package and deploy your AI models as Docker containers.
• Consistent Environments: Ensure models run consistently across development, testing, and production.
• Easy Management: Manage models through a simple REST API.
• Integration with Docker Desktop: Seamlessly integrates with your existing Docker Desktop setup.

Getting Started with Docker Model Runner

The easiest way to get started is by using the Makefile provided in the project. This simplifies common tasks.

Before you begin, make sure you have:

• Docker Desktop version 4.1 or greater installed.

Using the Makefile

The Makefile provides several helpful commands:

• make build: Compiles the Go application.
• make run: Runs the application locally.
• make clean: Removes the build artifacts.
• make help: Displays all available commands.

To build the application, simply run make build in your terminal. This creates an executable that you can then run locally with make run. If you need a reminder of the available commands, make help is your friend.

Interacting with the Docker Model Runner API

The Docker Model Runner exposes a REST API via a Unix socket file model-runner.sock. You can interact with this API using curl commands. Here are some examples:

Listing Available Models

Get a list of all available models:

curl --unix-socket model-runner.sock localhost/models

Creating a new model

Create a new model using a POST request:

curl --unix-socket model-runner.sock localhost/models/create -X POST -d '{"from": "ai/smollm2"}'

This command tells the Model Runner to create a model based on the "ai/smollm2" base image.

Getting Model Information

Retrieve information about a specific model:

curl --unix-socket model-runner.sock localhost/models/ai/smollm2

Replace ai/smollm2 with the actual model name to get its details. This is helpful for confirming the model's status and configuration.

Chatting with a Model

Send a chat request to a model:

curl --unix-socket model-runner.sock localhost/engines/llama.cpp/v1/chat/completions -X POST -d '{
  "model": "ai/smollm2",
  "messages": [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Hello, how are you?"}
  ]
}'

This command sends a chat message to the specified model ("ai/smollm2"). The message includes a system prompt and a user query. The response will contain the model's reply.

Understanding the Chat Response

The response from the chat endpoint will be in JSON format:

{
  "id": "chat-12345",
  "object": "chat.completion",
  "created": 1682456789,
  "model": "ai/smollm2",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "I'm doing well, thank you for asking! How can I assist you today?"
      },
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 24,
    "completion_tokens": 16,
    "total_tokens": 40
  }
}

Key details include the model's "content", which contains the actual response, and "usage", which shows token consumption.

Deleting a Model

Remove a model from the server:

curl --unix-socket model-runner.sock localhost/models/ai/smollm2 -X DELETE

Remember to replace ai/smollm2 with the model you intend to delete.
