NVIDIA NGC (nvcr.io)
NVIDIA's registry for GPU Operator, CUDA, Triton, NIM and other GPU images.
| Host | Ports | Purpose | |
|---|---|---|---|
| nvcr.io | 443 | Registry API (manifests and blobs) | required |
| authn.nvidia.com | 443 | Token authentication for nvcr.io | required |
| api.ngc.nvidia.com | 443 | NGC catalog API (used by the ngc CLI, not by plain pulls) | optional |
Notes
For a working GPU node you typically also need the NVIDIA driver repositories (developer.download.nvidia.com) opened for the host OS or the driver container - that is a package repo, not a registry, but it fails in the same change window. Authenticated pulls (NIM, enterprise images) use an API key as password against authn.nvidia.com.
