Container Environments

Deploy NeMo Curator in containerized environments for reproducible, scalable data curation pipelines with pre-configured dependencies and optimized runtime settings.

Overview

NeMo Curator provides official Docker containers with all dependencies pre-installed and optimized for production workloads. Containers offer:

• Reproducible Environments: Consistent software stack across development, testing, and production
• Simplified Deployment: No manual dependency installation or environment configuration
• GPU Acceleration: Pre-configured CUDA, cuDNN, and NVIDIA libraries for optimal performance
• Multi-Modal Support: Built-in support for text, image, video, and audio curation
• Cloud-Ready: Compatible with Kubernetes, Docker Swarm, and cloud container orchestries

When to use containers:

• Production deployments requiring consistency and reliability
• Multi-node cluster processing with identical environments
• CI/CD pipelines for automated data curation workflows
• Quick prototyping without local environment setup
• GPU-accelerated processing in cloud environments

Available Containers

Main NeMo Curator Container

The primary container includes comprehensive support for all curation modalities:

Container registry: nvcr.io/nvidia/nemo-curator:container_version“

Supported modalities:

• ✅ Text curation (CPU/GPU)
• ✅ Image curation (GPU required)
• ✅ Video curation (GPU required, FFmpeg included)
• ✅ Audio curation (GPU required for ASR)

Pre-installed components:

• NeMo Curator with all optional dependencies ([all] extras)
• CUDA 12.8.1 with cuDNN
• Python 3.12 with uv package manager
• FFmpeg 8+ with NVENC support (for video processing)
• Ray, Dask, and distributed computing frameworks
• NVIDIA optimized Python packages

Curator Environment

Security Hardening

The container build includes the following security measures:

• ray_dist.jar removal: Ray’s Java support JAR is deleted during the build to remove a bundled jackson-core library affected by GHSA-72hv-8253-57qq (DoS via async JSON parser). NeMo Curator does not use Ray’s Java support, so this has no functional impact. A build-time verification guard fails the build if the JAR is not successfully removed.

Container Build Arguments

The main container accepts these build-time arguments for environment customization:

Environment Usage Examples

Text Curation

Uses the default container environment with CPU or GPU workers depending on the module.

Image Curation

Requires GPU-enabled workers in the container environment.
