# Support Matrix

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

## Supported Platforms

OpenShell publishes multi-architecture gateway images for `linux/amd64` and `linux/arm64`. The CLI, package-managed gateway, and standalone gateway binary are supported on the following host platforms:

| Platform                         | Architecture          | Status       |
| -------------------------------- | --------------------- | ------------ |
| 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\_64               | Experimental |

On Linux, the `openshell` CLI is a static musl binary and does not require glibc at runtime.

## Standalone Gateway Binary

OpenShell publishes standalone `openshell-gateway` release assets for manual download on these platforms:

| Platform              | Artifact pattern                              |
| --------------------- | --------------------------------------------- |
| Linux x86\_64 (amd64) | `openshell-gateway-x86_64-unknown-linux-gnu`  |
| Linux aarch64 (arm64) | `openshell-gateway-aarch64-unknown-linux-gnu` |
| macOS Apple Silicon   | `openshell-gateway-aarch64-apple-darwin`      |

These artifacts are attached to GitHub releases. Kubernetes deployments should use the Helm chart and the published gateway image.

On Linux, `openshell-gateway` requires glibc 2.31 or newer. Compatible systems include, for example, Ubuntu 20.04+, RHEL 9+, Amazon Linux 2023+, and Fedora 32+.

## Compute Drivers

The gateway can manage sandboxes through several compute drivers.

| Compute Driver | Status                                                                                                                       | Notes                                                              |

| Docker         | Supported for local development and single-machine gateways.                                                                 | Requires Docker Desktop or Docker Engine on the gateway host.      |
| Podman         | Supported for rootless local and workstation workflows.                                                                      | Requires a Podman-compatible socket and rootless networking setup. |
| Kubernetes     | Supported through the [OpenShell Helm chart](https://github.com/NVIDIA/OpenShell/blob/main/deploy/helm/openshell/README.md). | Requires a Kubernetes cluster supplied by the operator.            |
| MicroVM        | Supported for VM-backed sandboxes.                                                                                           | Uses the VM compute driver and libkrun-based runtime.              |

## Software Prerequisites

Install the software for the compute driver you use:

| Component                       | Minimum Version              | Notes                                                                                              |
| ------------------------------- | ---------------------------- | -------------------------------------------------------------------------------------------------- |

## Sandbox Runtime Versions

Sandbox container images are maintained in the [openshell-community](https://github.com/nvidia/openshell-community) repository. Refer to that repository for the current list of installed components and their versions.

## Container Images

OpenShell publishes the gateway image for `linux/amd64` and `linux/arm64`.

| Image   | Reference                                 | Pulled When                                                       |
| ------- | ----------------------------------------- | ----------------------------------------------------------------- |
| Gateway | `ghcr.io/nvidia/openshell/gateway:latest` | Helm chart install or upgrade, or standalone container deployment |

The Helm chart in `deploy/helm/openshell` deploys the gateway StatefulSet, service account, service, persistent storage, and network policy for Kubernetes.

Sandbox images are maintained separately in the [openshell-community](https://github.com/nvidia/openshell-community) repository.

To override the default image references, use Helm values:

| Helm value                       | Purpose                               |
| -------------------------------- | ------------------------------------- |
| `image.repository` / `image.tag` | Override the gateway image reference. |
| `server.sandboxImage`            | Override the default sandbox image.   |

## Kernel Requirements

OpenShell enforces sandbox isolation through two Linux kernel security modules:

| Module                                                         | Requirement | Details                                                                                                                                                                                                                                          |
| -------------------------------------------------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| [Landlock LSM](https://docs.kernel.org/security/landlock.html) | Recommended | Enforces 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. |
| seccomp                                                        | Required    | Filters 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.
