This page lists the platform, software, runtime, and kernel requirements for running OpenShell.

Supported Platforms

OpenShell publishes multi-architecture container images for linux/amd64 and linux/arm64. The CLI is supported on the following host platforms:

PlatformArchitectureStatus
Linux (Debian/Ubuntu)x86_64 (amd64)Supported
Linux (Debian/Ubuntu)aarch64 (arm64)Supported
macOS (Docker Desktop)Apple Silicon (arm64)Supported
Windows (WSL 2 + Docker Desktop)x86_64Experimental

Software Prerequisites

The following software must be installed on the host before using the OpenShell CLI:

ComponentMinimum VersionNotes
Docker Desktop or Docker Engine28.04Must be running before any openshell command.

Sandbox Runtime Versions

Sandbox container images are maintained in the openshell-community repository. Refer to that repository for the current list of installed components and their versions.

Container Images

OpenShell publishes two container images. Both are published for linux/amd64 and linux/arm64.

ImageReferencePulled When
Clusterghcr.io/nvidia/openshell/cluster:latestopenshell gateway start
Gatewayghcr.io/nvidia/openshell/gateway:latestCluster startup (via Helm chart)

The cluster image bundles the Helm charts, Kubernetes manifests, and the openshell-sandbox supervisor binary required to bootstrap the control plane. The supervisor binary is side-loaded into sandbox pods at runtime through a read-only host volume mount. The gateway image is pulled at cluster startup and runs the API server.

Sandbox images are maintained separately in the openshell-community repository.

To override the default image references, set the following environment variables:

VariablePurpose
OPENSHELL_CLUSTER_IMAGEOverride the cluster image reference.
OPENSHELL_COMMUNITY_REGISTRYOverride the registry for community sandbox images.

Kernel Requirements

OpenShell enforces sandbox isolation through two Linux kernel security modules:

ModuleRequirementDetails
Landlock LSMRecommendedEnforces filesystem access restrictions at the kernel level. The best_effort compatibility mode uses the highest Landlock ABI the host kernel supports. The hard_requirement mode fails sandbox creation if the required ABI is unavailable.
seccompRequiredFilters dangerous system calls. Available on all modern Linux kernels (3.17+).

On macOS, these kernel modules run inside the Docker Desktop Linux VM, not on the host kernel.

Agent Compatibility
