air-gapped system, which is isolated from the Internet, you must provide these updates from a
private repository that mirrors the public repositories.
1. Identify the sources corresponding to the public NVIDIA and Canonical repositories that
provide updates to the DGX Station software.
You can identify these sources from the /etc/apt/sources.list file and the contents of
/etc/apt.sources.list.d/ directory, or by using System Settings, Software & Updates.
2. Create and maintain a private repository that mirrors the sources that you identified in the
previous step.
For detailed instructions, refer to Debian Repository Setup (https://wiki.debian.org/
DebianRepository/Setup) on the Debian wiki.
3. Update the sources that provide updates to the DGX Station to use your private repository
instead of the public repositories.
You can update these sources by modifying the /etc/apt/sources.list file and the
contents of /etc/apt.sources.list.d/ directory, or by using System Settings, Software
& Updates.
Future updates to the DGX Station software will be obtained from your private repository.
3.7.2. Loading a Container Image onto an Air-
Gapped DGX Station System
Loading a container image from the NGC Container Registry requires an Internet connection.
On an air-gapped system, which is isolated from the Internet, you must use a removable
medium to copy the container image from a system with an Internet connection to the air-
gapped system.
1. On a system with an Internet connection, log in to the NGC Container Registry and load the
container image that you want.
For instructions, refer to NGC Container Registry for DGX User Guide.
2. Save the container image as a tar archive.
$ docker save nvcr.io/registry-space/repository:tag > archive-file.tar
registry-space
The name of the space within the registry that contains the container image. For
container images provided by NVIDIA, the registry space is nvidia.
repository
The repository that contains the container image. A repository is a collection of all
versions of a container image with the same name. The repository name is the main
container image name.
tag
A tag that identifies the version of the container image.
archive-file
Your choice of name for the archive file to which you are saving the container image.
3. Transfer the image to the air-gapped system by using a removable medium such as a USB
flash drive or DVD-ROM.
