Connect Runtime Container to Your Operation

Based on the notes provided in the image, I'll help you create a tutorial on accessing the agent runtime after deploying it to Docker. This tutorial will explain the steps for building the Docker container, deploying the agent, and accessing the runtime for inference or interaction.

Tutorial: Accessing the Agent Runtime After Deploying to Docker

Once you have packaged and deployed your agent inside a Docker container, the next step is accessing its runtime for operations like model inference. This tutorial will guide you through the process of building and running the Docker container and then connecting to the agent's runtime for further interactions.

Step 1: Preparing the Dockerfile and Environment

To deploy the agent to Docker, we need to first create a Dockerfile. The Dockerfile will package the necessary runtime, model, and environment for the agent.

  1. Dockerfile Setup: Your Dockerfile should contain the following key components:

    • Base Image: Use a Python base image (or any base that supports the necessary libraries).

    • Copy Model Files: Copy the pre-trained model (e.g., .gz file) to the container.

    • Install Dependencies: Install any required Python libraries (like OHTTP or other packages for the agent).

Here’s an example Dockerfile:

# Use an official Python runtime as the base image
FROM python:3.10-slim

# Set the working directory
WORKDIR /usr/src/app

# Copy the necessary files into the Docker image
COPY . .

# Install any dependencies specified in requirements.txt
RUN pip install --no-cache-dir -r requirements.txt

# Expose port 8000 for the HTTP server
EXPOSE 8000

# Command to run the server when the container starts
CMD ["python", "agent_inference.py"]

Step 2: Building the Docker Image

  1. Building the Image: You can build the Docker image by running the following command in the terminal. This will take the Dockerfile and the associated files (like the pre-trained model) and create an image.

docker build -t my-agent-runtime .

  • The -t flag allows you to tag the image (my-agent-runtime), which makes it easier to reference later.

  • Make sure that the model file (agent.gz) and all relevant scripts are reachable within the Docker context (i.e., the directory from which you are building).

  1. Checking the Image: Once the build is complete, you can verify that the image was created successfully by running:

docker images

Step 3: Running the Docker Container

Now that the image is built, the next step is to run it in a container. You will run the Docker container in an interactive mode to access the runtime.

docker run -it -p 8000:8000 my-agent-runtime

  • -it: Runs the container interactively.

  • -p 8000:8000: Maps port 8000 from the container to port 8000 on your local machine so that you can access the HTTP server for the agent runtime.

The HTTP server should now be up and running within the container, ready to handle model inference or other tasks.

Step 4: Accessing the Agent Runtime

With the Docker container running, you can now connect to the agent's runtime. The runtime will be an HTTP server, as mentioned in your notes. You can access it through a POST request for model inference or other operations.

  1. Sending Requests to the Agent: You can send a POST request to the running server using a tool like curl, Postman, or any Python HTTP library (such as requests).

Here’s an example using curl:

curl -X POST http://localhost:8000/infer -d '{"input_data": "your_input_here"}'

This request will:

  • POST data to the /infer endpoint on localhost:8000, which is being forwarded from the Docker container.

  • The agent will handle the request, infer the model, and return the result.

  1. Interacting with the Agent: If you prefer to interact with the agent directly, you can also enter the container’s interactive mode and run commands.

docker exec -it <container_id> bash

This will open a shell inside the running Docker container, allowing you to execute any runtime commands manually.

Step 5: Automating the Process

For convenience, you can automate the entire process of building the image, running the container, and interacting with the agent by creating a script.

Here’s a basic example of an automation script:

#!/bin/bash

# Build the Docker image
docker build -t my-agent-runtime .

# Run the Docker container
docker run -it -p 8000:8000 my-agent-runtime

Save this as run_agent.sh, and then execute it:

bash run_agent.sh

This script will:

  • Build the Docker image.

  • Run the container, mapping the necessary port and exposing the HTTP server for inference.

Step 6: Troubleshooting and Debugging

If the container fails to start, or if the server doesn't respond, you can debug the container by checking the logs:

docker logs <container_id>

This command will display the output of the running container, which can help diagnose issues like missing dependencies or server errors.

Conclusion

In this tutorial, we walked through the process of:

  • Building a Docker image with your agent and its runtime.

  • Running the Docker container interactively to expose the agent’s HTTP server.

  • Accessing the agent runtime by sending HTTP requests for inference or other tasks.

By following these steps, you can deploy and interact with your Composabl agent in a Dockerized environment._
