Deploying Your Model with Triton in 3 Simple Steps

Getting started with Triton Inference Server is remarkably straightforward. Follow these three steps to quickly deploy and serve your AI models:

1. Set up your Model Repository:
   Begin by cloning the Triton Server repository and fetching example models. This establishes the foundation for organizing your models for Triton to access.

   git clone -b r25.01 https://github.com/triton-inference-server/server.git
   cd server/docs/examples
   ./fetch_models.sh

2. Launch Triton Server with Docker:
   Utilize the NVIDIA NGC Triton container to launch the server. This containerized approach simplifies deployment and ensures a consistent environment. Mount your model repository to make your models available to Triton.

   docker run --gpus=1 --rm --net=host -v ${PWD}/model_repository:/models nvcr.io/nvidia/tritonserver:25.01-py3 tritonserver --model-repository=/models

3. Send an Inference Request:
   In a separate terminal, use the Triton SDK container to send an inference request to your deployed model. This step demonstrates how client applications interact with Triton. The example uses the image_client to send an image for inference to the densenet_onnx model.

   docker run -it --rm --net=host nvcr.io/nvidia/tritonserver:25.01-py3-sdk /workspace/install/bin/image_client -m densenet_onnx -c 3 -s INCEPTION /workspace/images/mug.jpg

   Upon successful inference, you should receive a response similar to the following, indicating the model’s predictions:

   Image '/workspace/images/mug.jpg':
       15.346230 (504) = COFFEE MUG
       13.224326 (968) = CUP
       10.422965 (505) = COFFEEPOT
