Overview
Process of selecting inference backends, endpoints, and filesystem support to define the scope of a custom Triton Inference Server container build.
Description
Before building a custom container, operators must decide which ML frameworks (ONNX Runtime, TensorRT, PyTorch, OpenVINO, Python), network endpoints (HTTP, gRPC, SageMaker, Vertex AI), and cloud storage backends (S3, GCS, Azure) to include. This determines build dependencies, container size, and supported model types. The choice between compose (pre-built binary extraction) and source build (full compilation) depends on customization needs.
The build requirements planning phase is the critical first step in the Custom Container Build workflow. Each selection has downstream consequences:
- Backend selection determines which model frameworks the server can load and execute. Selecting only the backends needed for a deployment scenario reduces the final container image size and attack surface.
- Endpoint selection determines how clients communicate with the server. HTTP and gRPC are the standard protocols, while SageMaker and Vertex AI endpoints enable integration with managed cloud ML platforms.
- Filesystem selection determines where models can be loaded from. Enabling S3, GCS, or Azure Storage allows the server to pull models directly from cloud object stores without local staging.
- GPU enablement determines whether CUDA and TensorRT GPU acceleration are available. Disabling GPU support produces a CPU-only build suitable for edge deployments or cost-sensitive workloads.
Usage
Build requirements planning is performed at the start of every custom container build. Typical scenarios include:
- Minimal production image: Select only the one or two backends needed (e.g., TensorRT + Python), HTTP endpoint, no cloud filesystems. This produces the smallest possible image.
- Full-featured development image: Use
--enable-allto include every backend, endpoint, and filesystem for maximum flexibility during development and testing. - Cloud-native deployment: Select required backends plus the cloud filesystem matching the deployment environment (e.g., S3 for AWS, GCS for GCP).
- Edge/embedded deployment: Select minimal backends, disable GPU if targeting CPU-only hardware, and use the compose path for fastest build times.
Theoretical Basis
The principle follows a modular composition pattern:
- Select backends based on the model formats that will be served
- Determine dependencies that each backend requires (CUDA, cuDNN, TensorRT libraries)
- Choose build path (compose vs source) based on customization needs
The core tradeoff is:
| Factor | More Backends | Fewer Backends |
|---|---|---|
| Container Size | Larger (multi-GB) | Smaller (reduced footprint) |
| Build Time | Longer (more compilation or extraction) | Shorter |
| Model Support | Broader (many frameworks) | Narrower (specific frameworks only) |
| Attack Surface | Larger | Smaller |
The compose path is preferred when no source modifications are needed, as it extracts pre-built binaries from NGC images. The source build path is required when operators need to modify server behavior, add custom backends, enable debug symbols, or build for unsupported platforms.
