* feat(k8s): add namespace-per-workspace support (RFC 0011 Phase 3) Implement three workspace namespace modes for the Kubernetes compute driver: shared (default, preserves current single-namespace behavior), managed (auto-creates/deletes namespaces per workspace), and operator (pre-provisioned namespaces with dynamic discovery via label selector or drop-in allowlist file). Key changes: - WorkspaceMode enum and namespace resolution in driver config - Managed namespace lifecycle with ServiceAccount and OpenShift SCC annotation propagation - Cluster-wide sandbox CR watchers for managed/operator modes - NamespaceValidator (Exact/Prefix/Allowlist) for SA token auth - Workspace-aware credential secret storage - Helm ClusterRole for multi-namespace RBAC - Gateway config, architecture, and reference docs Signed-off-by: Derek Carr <decarr@redhat.com> * test(k8s): add e2e tests for workspace namespace modes Add end-to-end tests for managed and operator workspace modes introduced in RFC 0011 Phase 3. The managed mode tests verify namespace creation with correct labels, ServiceAccount provisioning, sandbox CR placement, and namespace survival with remaining sandboxes. The operator mode tests verify rejection of unlabeled and nonexistent namespaces. The positive operator path (sandbox in labeled namespace) is known to fail due to an RBAC gap and will be addressed separately. Also fixes Helm 4 compatibility: move SPDX license headers inside conditional guards in 8 chart templates to prevent empty comment-only documents, and fix a trailing whitespace trimmer in clusterrole.yaml that concatenated the license header with apiVersion. Adds cleanup sweep in with-kube-gateway.sh to remove managed and operator namespaces before Helm uninstall, and mise tasks for running each mode independently. Signed-off-by: Derek Carr <decarr@redhat.com> * feat(k8s): add operator namespace label watcher Spawn a background kube::runtime::watcher in the K8s driver that watches namespaces matching the configured label selector and populates the OperatorNamespaceAllowlist at runtime. The driver owns the allowlist and exposes its Arc so the server can share the same set with the SA token authenticator. create_sandbox now gates pod creation on the allowlist in operator mode — workspaces whose namespace is not yet labeled are rejected at resource render time rather than silently proceeding. Workspace lifecycle itself is unaffected; only sandbox (resource) creation is gated. Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): harden operator mode and address review findings Close the fail-open gap in operator mode when only operator_namespace_file is configured: the allowlist is now created unconditionally in operator mode (fail-closed from startup). Implement the namespace file watcher using the notify crate, following the TLS hot-reload pattern (parent-directory watch, 1s debounce, ConfigMap symlink-swap safe). The file format is a JSON array of namespace name strings. Additional fixes from the 10-reviewer audit: - Change allowlist rejection from InvalidArgument to FailedPrecondition so callers know the request may succeed later once the namespace is provisioned. - NamespaceValidator::Allowlist now holds the OperatorNamespaceAllowlist newtype instead of a raw Arc<RwLock<BTreeSet>>, eliminating silent denial on RwLock poison. - Verify LABEL_MANAGED_BY and LABEL_GATEWAY_ID ownership before deleting a managed namespace. - Replace fixed 5s sleep in operator e2e test with a 30s poll loop. - Add Helm validation for workspaceMode values. - Fix Helm README type column and description for operator fields. - Add insert/remove methods to OperatorNamespaceAllowlist; label watcher now uses them instead of reaching through shared(). - Reject configs with both operator_namespace_label and operator_namespace_file set. Signed-off-by: Derek Carr <decarr@redhat.com> * feat(k8s): add workspace-level compute driver RPCs and harden RBAC Decouple namespace lifecycle from sandbox lifecycle by adding EnsureWorkspace/DeleteWorkspace RPCs to the ComputeDriver service. Namespace creation now happens before credential storage and namespace deletion happens on workspace delete, fixing credential storage in managed workspace mode. - Add EnsureWorkspace and DeleteWorkspace proto RPCs with implementations across all compute drivers (K8s managed delegates to ensure_namespace/delete_namespace_if_empty; others no-op) - Wire ensure_workspace into provider create/update/refresh paths so the namespace exists before the credential driver writes secrets - Wire delete_workspace into workspace deletion for cleanup - Remove delete_namespace_if_empty from sandbox deletion path - Scope ClusterRole secrets access to non-shared workspace modes - Add TODO for TLS cert hot-reload in sandbox gRPC client - Harden e2e tests with control-plane sandbox resolution assertions - Fix docker image save --platform flag for OCI index manifests Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): address re-review findings and add test coverage - Use server-side apply for TLS secret sync (fixes second sandbox creation failure when TLS is enabled) - Scope gateway-ID label selector unconditionally across all workspace modes (fixes operator reads/watches/deletes seeing foreign sandboxes) - Validate operator allowlist in EnsureWorkspace and DeleteWorkspace RPCs (prevents credential writes to namespaces outside the allowlist) - Extend ClusterRole secrets patch+delete to all non-shared modes with credential driver enabled (fixes operator credential storage RBAC) - Validate namespace ownership on 409 conflict in ensure_namespace (prevents adopting unowned namespaces in managed mode) - Replace delete_namespace_if_empty with unconditional delete_namespace letting Kubernetes cascade cleanup (fixes stuck terminating CRs) - Strengthen NetworkPolicy TODO to cover both managed and operator modes - Extract selector and ownership logic into testable free functions - Add unit tests for gateway-ID selectors and namespace ownership - Add Helm ClusterRole RBAC tests for operator credential driver Signed-off-by: Derek Carr <decarr@redhat.com> * ci(k8s): add workspace managed and operator mode e2e to CI Wire the existing e2e:kubernetes:workspace-managed and e2e:kubernetes:workspace-operator mise tasks into the branch-e2e workflow so they run alongside the other core Kubernetes e2e suites. Both are gated by run_core_e2e and included in the Core E2E result gate. Signed-off-by: Derek Carr <decarr@redhat.com> * test(k8s): add e2e tests for workspace namespace modes Add 7 new e2e tests covering workspace namespace lifecycle, TLS secret copying, ownership conflict detection, DNS-1123 validation, operator namespace preservation, and dynamic label watcher behavior. Fix async sandbox deletion race condition in existing tests by polling sandbox list instead of asserting immediately after delete. Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): grant secrets/patch unconditionally and backfill gateway-id labels Address two review findings: 1. RBAC: server-side apply (PATCH) is used for TLS secret sync in multi-namespace modes, but the ClusterRole only granted patch when the kubernetes-secrets credential driver was enabled. Grant patch unconditionally for non-shared modes since TLS sync always needs it; keep delete gated on the credential driver. 2. Upgrade safety: the new gateway-id label selector would orphan legacy Sandbox CRs that predate its introduction. Add a startup backfill in shared mode that patches any managed Sandbox CR missing the gateway-id label before the driver begins serving requests. Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): address workspace namespace review findings Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): address follow-up review findings Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): preserve workspace lookup after rebase Signed-off-by: Derek Carr <decarr@redhat.com> * fix(helm): allow managed secret creation Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): stop pods in workspace namespace Signed-off-by: Derek Carr <decarr@redhat.com> * test(k8s): scope pod deletion check to v1alpha1 Signed-off-by: Derek Carr <decarr@redhat.com> * fix(k8s): address workspace namespace review findings Signed-off-by: Derek Carr <decarr@redhat.com> --------- Signed-off-by: Derek Carr <decarr@redhat.com>
OpenShell is the safe, private runtime for autonomous AI agents. It provides sandboxed execution environments that protect your data, credentials, and infrastructure — governed by declarative YAML policies that prevent unauthorized file access, data exfiltration, and uncontrolled network activity.
OpenShell is built agent-first. The project ships with agent skills for everything from gateway troubleshooting to policy generation, and we expect contributors to use them.
Alpha software — single-player mode. OpenShell is proof-of-life: one developer, one environment, one gateway. We are building toward multi-tenant enterprise deployments, but the starting point is getting your own environment up and running. Expect rough edges. Bring your agent.
Quickstart
Prerequisites
- A supported host — Linux, macOS (Apple Silicon), or Windows with WSL 2 (experimental).
- A local runtime — Docker, Podman, or host virtualization enabled for MicroVM-backed sandboxes.
Install
Binary (recommended):
curl -LsSf https://raw.githubusercontent.com/NVIDIA/OpenShell/main/install.sh | sh
From PyPI (requires uv):
uv tool install -U openshell
Both methods install the latest stable release by default. To install a specific version, set OPENSHELL_VERSION (binary) or pin the version with uv tool install openshell==<version>. A dev release is also available that tracks the latest commit on main.
Helm chart:
Experimental — the Kubernetes deployment path is under active development. Expect rough edges and breaking changes.
Deploy the OpenShell gateway into a Kubernetes cluster from the OCI chart published to GHCR:
helm install openshell oci://ghcr.io/nvidia/openshell/helm-chart
See deploy/helm/openshell/README.md for available versions, dev tag conventions, and configuration.
For deploying OpenShell on OpenShift, see deploy/helm/openshell/README.md#install-on-openshift.
Create a sandbox
openshell sandbox create -- claude # or opencode, codex, copilot
The sandbox container includes the following tools by default:
| Category | Tools |
|---|---|
| Agent | claude, opencode, codex, copilot |
| Language | python (3.14), node (22) |
| Developer | gh, git, vim, nano |
| Networking | ping, dig, nslookup, nc, traceroute, netstat |
For more details see https://github.com/NVIDIA/OpenShell-Community/tree/main/sandboxes/base.
See network policy in action
Every sandbox starts with minimal outbound access. You open additional access with a short YAML policy that the proxy enforces at the HTTP method and path level, without restarting anything.
# 1. Create a sandbox (starts with minimal outbound access)
openshell sandbox create
# 2. Inside the sandbox — blocked
sandbox$ curl -sS https://api.github.com/zen
curl: (56) Received HTTP code 403 from proxy after CONNECT
# 3. Back on the host — apply a read-only GitHub API policy
sandbox$ exit
openshell policy set demo --policy examples/sandbox-policy-quickstart/policy.yaml --wait
# 4. Reconnect — GET allowed, POST blocked by L7
openshell sandbox connect demo
sandbox$ curl -sS https://api.github.com/zen
Anything added dilutes everything else.
sandbox$ curl -sS -X POST https://api.github.com/repos/octocat/hello-world/issues -d '{"title":"oops"}'
{"error":"policy_denied","detail":"POST /repos/octocat/hello-world/issues not permitted by policy"}
See the full walkthrough or run the automated demo:
bash examples/sandbox-policy-quickstart/demo.sh
How It Works
OpenShell isolates each sandbox in its own container with policy-enforced egress routing. A lightweight gateway coordinates sandbox lifecycle, and every outbound connection is intercepted by the policy engine, which does one of three things:
- Allows — the destination and binary match a policy block.
- Routes for inference — strips caller credentials, injects backend credentials, and forwards to the managed model.
- Denies — blocks the request and logs it.
| Component | Role |
|---|---|
| Gateway | Control-plane API that coordinates sandbox lifecycle and acts as the auth boundary. |
| Sandbox | Isolated runtime with container supervision and policy-enforced egress routing. |
| Policy Engine | Enforces filesystem, network, and process constraints from application layer down to kernel. |
| Privacy Router | Privacy-aware LLM routing that keeps sensitive context on sandbox compute. |
OpenShell runs a gateway control plane that manages sandbox lifecycle through a configured compute driver. Supported compute platforms include Docker, Podman, MicroVM, and Kubernetes.
Protection Layers
OpenShell applies defense in depth across four policy domains:
| Layer | What it protects | When it applies |
|---|---|---|
| Filesystem | Prevents reads/writes outside allowed paths. | Locked at sandbox creation. |
| Network | Blocks unauthorized outbound connections. | Hot-reloadable at runtime. |
| Process | Blocks privilege escalation and dangerous syscalls. | Locked at sandbox creation. |
| Inference | Reroutes model API calls to controlled backends. | Hot-reloadable at runtime. |
Policies are declarative YAML files. Static sections (filesystem, process) are locked at creation; dynamic sections (network, inference) can be hot-reloaded on a running sandbox with openshell policy set.
Providers
Agents need credentials — API keys, tokens, service accounts. OpenShell manages these as providers: named credential bundles that are injected into sandboxes at creation. The CLI auto-discovers credentials for recognized agents (Claude, Codex, OpenCode, Copilot) from your shell environment, or you can create providers explicitly with openshell provider create. Credentials never leak into the sandbox filesystem; they are injected as environment variables at runtime.
GPU Support (Experimental)
Experimental — GPU passthrough works on supported hosts but is under active development. Expect rough edges and breaking changes.
OpenShell can pass host GPUs into sandboxes for local inference, fine-tuning, or any GPU workload. Add --gpu when creating a sandbox:
openshell sandbox create --gpu --from [gpu-enabled-sandbox] -- claude
Docker-backed GPU sandboxes auto-select CDI when available and otherwise fall back to Docker's NVIDIA GPU request path (--gpus all).
Requirements: NVIDIA drivers and the NVIDIA Container Toolkit must be installed on the host. The sandbox image itself must include the appropriate GPU drivers and libraries for your workload — the default base image does not. See the BYOC example for building a custom sandbox image with GPU support.

Explore with Your Agent
Clone the repo and point your coding agent at it. The project includes agent skills that can answer questions, walk you through workflows, and diagnose problems — no issue filing required.
git clone https://github.com/NVIDIA/OpenShell.git # or git@github.com:NVIDIA/OpenShell.git
cd OpenShell
# Point your agent here — it will discover the skills in .agents/skills/ automatically
Your agent can load skills for CLI usage (openshell-cli), gateway troubleshooting (debug-openshell-cluster), inference troubleshooting (debug-inference), policy generation (generate-sandbox-policy), and more. See CONTRIBUTING.md for the full skills table.
Built With Agents
OpenShell is developed using the same agent-driven workflows it enables. The .agents/skills/ directory contains workflow automation that powers the project's development cycle:
- Spike and build: Investigate a problem with
create-spike; a human accepts it withstate:acceptedor roadmap placement, or declines it. Accepted work can remain human-owned or enter the optional, human-gatedagent:*planning and implementation workflow. - Triage and route: Community issues are assessed with
triage-issue. Agents establish technical validity and impact; humans decide whether the project should act and where the work sits on the roadmap. - Security review:
review-security-issueproduces a severity assessment and remediation plan.fix-security-issueimplements it. - Policy authoring:
generate-sandbox-policycreates YAML policies from plain-language requirements or API documentation.
All agent implementation work is human-gated: maintainers explicitly request a plan, agents propose it, maintainers approve it, and agents build. See AGENTS.md for the full workflow chain documentation.

Contributing
OpenShell is built agent-first. Issues should include a user story, problem statement, impact, and acceptance criteria. The impact should explain the consequences of the current behavior and why existing workarounds are insufficient. Feature requests also require a workflow-level proposed design and alternatives; bug reports add reproduction steps, environment details, and relevant logs. Once maintainers accept work, contributors should use the skills in .agents/skills/ to investigate the current code and behavior, implement the change, and verify it. If an issue contains earlier diagnostics, verify them rather than relying on them. See CONTRIBUTING.md for the full agent skills table, contribution workflow, and development setup.
Telemetry
OpenShell collects anonymous telemetry to help improve the project for developers. This data is not used to track individual user behavior. It helps us understand aggregate usage of sandbox, provider, and policy workflows so we can prioritize product improvements and share usage trends with the community.
Disable telemetry at runtime by setting OPENSHELL_TELEMETRY_ENABLED=false on the gateway deployment. For Helm installs, set server.telemetryEnabled=false. OpenShell propagates this deployment setting into sandbox supervisor environments so sandbox-side telemetry collection is disabled as well.
You can also compile telemetry out entirely. Telemetry support is a default-on telemetry Cargo feature; building with --no-default-features produces binaries that contain no telemetry endpoint, no telemetry HTTP client, and no emission code. Build telemetry-free artifacts with, for example, cargo build --release -p openshell-server --no-default-features (gateway) and the equivalent for openshell-sandbox and openshell-driver-vm. With telemetry compiled out, the gateway emits nothing and reports telemetry disabled to the sandboxes it launches.
Telemetry events are limited to anonymous operational categories and counts, such as sandbox lifecycle outcomes, provider profile buckets, policy decision counts, and aggregate network activity denial categories. OpenShell telemetry does not collect sandbox names or IDs, hostnames, file paths, binary paths, prompts, credentials, provider names, model names, or user content.
Opting out applies only to telemetry emitted by OpenShell. Third-party services, model providers, inference endpoints, agents, or tools that you configure and use with OpenShell may have their own terms and privacy practices.
We publish aggregate usage trends from this telemetry every two weeks. See the community telemetry reports for the latest summary.
