Docker Quickstart Guide for Ultralytics

Ultralytics Docker Package Visual

This guide serves as a comprehensive introduction to setting up a Docker environment for your Ultralytics projects. Docker is a platform for developing, shipping, and running applications in containers. It is particularly beneficial for ensuring that the software will always run the same, regardless of where it's deployed. For more details, visit the Ultralytics Docker repository on Docker Hub.

Docker Pulls

What You Will Learn

  • Setting up Docker with NVIDIA support
  • Installing Ultralytics Docker images
  • Running Ultralytics in a Docker container
  • Mounting local directories into the container

Prerequisites

  • Make sure Docker is installed on your system. If not, you can download and install it from Docker's website.
  • Ensure that your system has an NVIDIA GPU and NVIDIA drivers are installed.

Setting up Docker with NVIDIA Support

First, verify that the NVIDIA drivers are properly installed by running:

nvidia-smi

Installing NVIDIA Docker Runtime

Now, let's install the NVIDIA Docker runtime to enable GPU support in Docker containers:

# Add NVIDIA package repositories
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
distribution=$(lsb_release -cs)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list

# Install NVIDIA Docker runtime
sudo apt-get update
sudo apt-get install -y nvidia-docker2

# Restart Docker service to apply changes
sudo systemctl restart docker

Verify NVIDIA Runtime with Docker

Run docker info | grep -i runtime to ensure that nvidia appears in the list of runtimes:

docker info | grep -i runtime

Installing Ultralytics Docker Images

Ultralytics offers several Docker images optimized for various platforms and use-cases:

  • Dockerfile: GPU image, ideal for training.
  • Dockerfile-arm64: For ARM64 architecture, suitable for devices like Raspberry Pi.
  • Dockerfile-cpu: CPU-only version for inference and non-GPU environments.
  • Dockerfile-jetson: Optimized for NVIDIA Jetson devices.
  • Dockerfile-python: Minimal Python environment for lightweight applications.
  • Dockerfile-conda: Includes Miniconda3 and Ultralytics package installed via Conda.

To pull the latest image:

# Set image name as a variable
t=ultralytics/ultralytics:latest

# Pull the latest Ultralytics image from Docker Hub
sudo docker pull $t

Running Ultralytics in Docker Container

Here's how to execute the Ultralytics Docker container:

# Run with all GPUs
sudo docker run -it --ipc=host --gpus all $t

# Run specifying which GPUs to use
sudo docker run -it --ipc=host --gpus '"device=2,3"' $t

The -it flag assigns a pseudo-TTY and keeps stdin open, allowing you to interact with the container. The --ipc=host flag enables sharing of host's IPC namespace, essential for sharing memory between processes. The --gpus flag allows the container to access the host's GPUs.

Note on File Accessibility

To work with files on your local machine within the container, you can use Docker volumes:

# Mount a local directory into the container
sudo docker run -it --ipc=host --gpus all -v /path/on/host:/path/in/container $t

Replace /path/on/host with the directory path on your local machine and /path/in/container with the desired path inside the Docker container.


Congratulations! You're now set up to use Ultralytics with Docker and ready to take advantage of its powerful capabilities. For alternate installation methods, feel free to explore the Ultralytics quickstart documentation.
