The listener resolves service hostnames and forwards HTTP and WebSocket traffic to the correct sandbox under its policy, independently of the supervisor's gateway control connection. + +Supervisors advertise services to the gateway for discovery. Operators can integrate their existing ingress with these listeners or use the optional `openshell-sandbox-proxy` reference implementation. Application traffic bypasses the gateway, allowing ingress to scale separately. Keep gateway routing available for simple deployments. + +## Motivation + +Service exposure needs the following: + +1. **Independent scaling.** Prevent application traffic from consuming resources needed for responsive control-plane operations. +2. **Independent access restrictions.** Apply separate network rules to control-plane and application traffic. +3. **Application-owned authentication.** Serve applications without requiring OpenShell request authentication, so applications can authenticate their own clients. +4. **Platform-managed authentication.** Protect applications through the authentication infrastructure used for the control plane, such as Cloudflare tunnels and zero-trust proxies. +5. **Routing to shared supervisors.** Support a future supervisor serving several sandboxes, each with its own policy. +6. **Extensible ingress.** Let operators integrate existing ingress through gateway discovery, with an optional OpenShell proxy as a reference implementation. + +## Non-goals + +- Implement multi-tenant supervisors; accommodate them in the routing design. +- Move SSH, execution, CLI port forwarding, or file uploads out of their current paths. +- Add arbitrary TCP/UDP exposure, automatic port discovery, or application replication. +- Replace egress policy, provider handling, or the isolation backend contract. +- Remove gateway routing or automatically migrate existing URLs. + +## Proposal + +### What we have today + +`openshell service expose my-sandbox 8080 web` registers a service and returns a URL shaped like `https://default--my-sandbox--web./`. + +The gateway resolves the HTTP hostname and carries application traffic through a supervisor relay to the sandbox's loopback port. Service requests bypass control-plane RPC authorization but share the gateway process, listener TLS requirements, and supervisor transport. + +### What is missing + +- **Independent scaling.** Another frontend or gateway listener still sends application payloads through the gateway. We need a separate path to supervisor app listeners. +- **Independent access restrictions.** Applications need separate listener ports and TLS policies. Different hostnames alone do not provide a network access boundary. +- **Authentication flexibility.** Applications can already receive bearer credentials or sit behind edge authentication, but inherit gateway TLS requirements. They need an independent application listener; service routes do not automatically inherit OpenShell OIDC or workspace authorization. +- **Service discovery.** Ingress needs to find the supervisor serving each sandbox and follow ownership changes, including when one supervisor serves several sandboxes. + +### Supervisor app listener + +The core feature is an application-only listener on each supervisor, separate from its gateway connection and management APIs. It resolves service hostnames, applies the selected sandbox's policy, and forwards traffic to that sandbox's declared service port. + +Supervisors reach services through each sandbox's isolation backend loopback connector, as defined in [RFC 0012](../0012-isolation-backend/README.md). Traffic never reaches sandboxes directly. + +The gateway manages declarations and discovery. The listener and discovery API provide integration points for operator-managed ingress and the optional OpenShell proxy. Either can select a supervisor using TLS Server Name Indication (SNI). + +```mermaid +flowchart TB + Client["Application clients"] -->|"Service SNI"| Ingress["Existing ingress or optional OpenShell proxy"] + Ingress -.->|"Discovery or discovery adapter"| Gateway["OpenShell gateway"] + SA["Supervisor A: app listener"] -.->|"Control and advertisements"| Gateway + SB["Supervisor B: app listener"] -.->|"Control and advertisements"| Gateway + Ingress -->|"A/web, B/web, B/portal"| SA + Ingress -->|"C/web"| SB + SA --> A["Sandbox A: web; policy A"] + SA --> B["Sandbox B: web and portal; policy B"] + SB --> C["Sandbox C: web; policy C"] +``` + +Solid arrows carry application traffic; dashed arrows carry control traffic. Discovery identifies the supervisor app endpoint independently of which gateway replica owns its control session. + +Application ingress scales independently of the gateway. Supervisors still share resources between application and control work, so connection, buffer, and per-sandbox concurrency limits must preserve control-plane capacity. + +### Driver integration + +The app listener and discovery contract are independent of the compute driver. Driver-specific networking provides reachability without changing service identity or supervisor policy enforcement. + +Each supported driver provisions a supervisor app listener and a reachable address for it, including any required port allocation or forwarding. The supervisor advertises accepted sandbox services through the gateway. Ingress implementers consume discovery and route to the owning supervisor; they can use existing ingress infrastructure or the optional OpenShell proxy. + +Addresses must be reachable from the chosen ingress deployment: loopback is sufficient only when ingress shares that network context. Multiple supervisors on one host need distinct listener ports or addresses. + +Drivers manage endpoint allocation, restart, replacement, and deletion; advertisements and discovery must track those changes. The advertised endpoint always reaches the supervisor app listener, never a workload port. These responsibilities leave service identity, discovery, and sandbox policy enforcement unchanged across drivers. + +Architectural support does not imply every driver ships in the first release. Enable supervisor ingress only after that driver's endpoint integration is implemented and validated. + +### Kubernetes + +Kubernetes operators can use existing ingress plus a discovery adapter to route to supervisor Services. This uses the same app listener and discovery contract. + +Supervisor Services are the Kubernetes mapping of the common driver contract; other drivers provide reachability through their own networking. + +Several sandbox services can share one supervisor Service. A Service spanning supervisors with different sandbox owners still needs routing that selects the correct owner. Ingress must preserve service SNI or use an explicitly supported TLS termination mode. + +### Optional reference proxy + +`openshell-sandbox-proxy` is an additional, optional binary with its own listener, discovery credentials, cache, limits, and metrics. Replicas can sit behind a load balancer and discover routes independently. + +It also serves as a reference implementation for integrating other ingress systems: consuming gateway route updates, selecting the owning supervisor by SNI, and connecting to its app listener. + +### Services and discovery + +Keep the existing workflow, including create-time exposure and unnamed services: + +```shell +openshell service expose sandbox-a 8080 web +openshell service expose sandbox-b 8080 web +openshell service expose sandbox-b 9000 portal +openshell service expose sandbox-c 8080 web +``` + +The gateway sends declarations to the owning supervisor. The supervisor installs permitted routes under each sandbox's policy and advertises them back. The gateway validates ownership and publishes accepted routes. An advertisement cannot broaden a declaration, and an advertised route does not prove the application is healthy. + +Add authenticated, read-only discovery with a snapshot and a watch for changes. Each route contains its hostname, sandbox and service IDs, supervisor identity and app address, revision, runtime generation, and expiry. Addresses come from trusted operator/driver configuration. Discovery access is scoped to the router's workspaces and includes no workload secrets. + +Routers cache routes rather than querying the gateway for each connection. Revisions and generations distinguish updates and sandbox replacements. Deletion, rejected configuration, or loss of ownership withdraws a route. Supervisors reject stale routes even if a proxy still has them cached; new owners advertise only after accepting the route. + +During discovery outages, the proposed default permits unexpired routes and rejects new connections after expiry. Revocation or sandbox teardown closes affected connections. Lease and draining rules remain open questions. Failures do not automatically fall back through the gateway. + +### SNI routing and policy + +The proposed default is TLS passthrough: ingress reads SNI, selects the advertised supervisor, and forwards the TLS stream. The supervisor app listener terminates TLS and proxies HTTP/WebSockets to the declared loopback port. Missing SNI and unknown or expired routes are rejected. + +For workspace `default`, the example routes are: + +| Service URL | Supervisor | Sandbox destination | +| --- | --- | --- | +| `https://default--sandbox-a--web.svc.openshell.internal/` | A | A: web, port 8080 | +| `https://default--sandbox-b--web.svc.openshell.internal/` | A | B: web, port 8080 | +| `https://default--sandbox-b--portal.svc.openshell.internal/` | A | B: portal, port 9000 | +| `https://default--sandbox-c--web.svc.openshell.internal/` | B | C: web, port 8080 | + +The supervisor checks each HTTP `Host` or HTTP/2 `:authority` against the connection's SNI and installed route. Mismatches are rejected. WebSockets stay bound to their admitted service. + +Before opening the sandbox connector, the supervisor checks ownership, generation, readiness, and that sandbox's policy. Clients cannot choose arbitrary ports. Connection pools, quotas, and logs stay scoped to the sandbox and service. A future shared supervisor must authenticate its authority over each sandbox separately. + +The ingress policy schema needs definition. Existing egress rules must not implicitly grant ingress access. + +### TLS and authentication + +Application TLS is configured separately from gateway TLS. Operators provide DNS and certificates; `svc.openshell.internal` is an example domain. Certificate provisioning and rotation remain open questions. + +SNI selects a route; it does not authenticate a user. Applications can handle authentication, or operators can apply an edge access policy. Preserve existing header handling: strip `Authorization` by default, allow explicit `bearer-passthrough`, and strip gateway/edge identity headers and edge authentication cookies. Native OpenShell user/workspace authorization is not the proposed default for application requests. + +A passthrough proxy cannot inspect HTTP credentials. An edge that terminates TLS must reconnect with the correct service SNI and authority. Restrict supervisor listener access to prevent bypassing required edge authentication; use authenticated backend transport where network restrictions are insufficient. + +### Deployment and compatibility + +Enable the new path explicitly and retain existing gateway-mode behavior. CLI/SDK URLs must use the application ingress domain and public port independently of the gateway endpoint. Status should distinguish configured, advertised, and unavailable routes. Domain migrations require coordinated DNS, TLS, and client changes. + +## Implementation plan + +Start with one sandbox per supervisor while preserving routing boundaries needed for shared supervisors. + +1. Define ingress policy, TLS, discovery credentials, route leases, and advertisement/discovery APIs following `proto/README.md`. +2. Add supervisor app listeners, service configuration sync, boundary routing, limits, and OCSF events. +3. Add gateway discovery and integrate the first supported drivers and ingress deployment. For each enabled driver, implement reachable endpoint provisioning and lifecycle updates. Update CLI/SDK URLs, deployment configuration, docs, and related skills. +4. Build the optional `openshell-sandbox-proxy` as a reference integration, with cached routes and direct supervisor connections. +5. Run sandbox E2E tests for HTTP/WebSockets, SNI/host mismatches, tenant policies, authentication, deletion, replacement, and discovery outages. Validate endpoint reachability and lifecycle for each enabled driver. Use fixtures for shared-supervisor routing until that runtime exists. Measure control-plane responsiveness under application load and test gateway-mode compatibility. + +## Risks + +- **Supervisor contention.** Application traffic still shares supervisor resources. Limits and load tests must show that control operations remain responsive. +- **Stale discovery.** Ownership changes and outages can interrupt service. Revisions, generations, expiry, and local checks must prevent routing to another sandbox. +- **Ingress security.** New listeners increase supervisor exposure. Bound connection/parser work, reject undeclared services, and prevent edge-authentication bypass. +- **Operational complexity.** Certificates, direct supervisor reachability, and two supported data paths add deployment and maintenance work. + +## Alternatives + +- **Keep gateway routing or split gateway listeners.** Separate listeners (#4210 / #4213) improve access control but retain gateway payload traffic. +- **Require the proxy everywhere.** This standardizes ingress but adds a component where operators already have suitable infrastructure. +- **Terminate TLS at the proxy.** This centralizes certificates and enables HTTP authentication, but requires a trusted proxy-to-supervisor routing contract. +- **Use reverse application tunnels.** These avoid inbound supervisor reachability but add tunnel ownership and reconnection machinery. Consider them for deployments behind NAT. + +## Prior art + +- #4266 and [PR #4267](https://github.com/NVIDIA/OpenShell/pull/4267) define the original requirements and options. This revision proposes supervisor listeners with an optional proxy. +- [RFC 0012](../0012-isolation-backend/README.md) provides the protected loopback connector into each sandbox. +- #994 and #1791 cover service declarations and Kubernetes ingress; #1794 and #3402 cover bearer handling and create-time exposure. +- #4229 covers service health. #2469 and #3715 cover dedicated/shared ingress integrations. + +## Open questions + +- Should TLS terminate at supervisors or the proxy? How are certificates provisioned and rotated? +- Does `service expose` grant ingress permission, or must policy also allow it? Which policy and middleware checks apply? +- How are discovery credentials scoped, and how does a shared supervisor authenticate ownership of each sandbox? +- What route expiry, outage grace, revocation acknowledgement, and connection-draining rules should apply? +- Which driver and ingress integration ship first? What backend authentication is required? +- What per-sandbox limits and control-plane latency targets demonstrate adequate resource isolation? diff --git a/sdk/go/openshell/v1/gateway/gateway.go b/sdk/go/openshell/v1/gateway/gateway.go index da7c9814b4..dde3545664 100644 --- a/sdk/go/openshell/v1/gateway/gateway.go +++ b/sdk/go/openshell/v1/gateway/gateway.go @@ -135,7 +135,7 @@ func ListGateways() ([]Info, error) { } } - sysNames, listErr := listGatewayDirs(systemConfigBase) + sysNames, listErr := listGatewayDirs(systemConfigDir()) if listErr != nil { return nil, listErr } diff --git a/sdk/go/openshell/v1/gateway/gateway_test.go b/sdk/go/openshell/v1/gateway/gateway_test.go index ec519c29a6..e22a0a7873 100644 --- a/sdk/go/openshell/v1/gateway/gateway_test.go +++ b/sdk/go/openshell/v1/gateway/gateway_test.go @@ -409,6 +409,7 @@ func TestLoadConfig_ActiveGateway(t *testing.T) { func TestListGateways_MultipleGateways(t *testing.T) { tmp := t.TempDir() t.Setenv("XDG_CONFIG_HOME", tmp) + t.Setenv(systemGatewayDirEnv, tmp) for _, name := range []string{"prod", "staging", "dev"} { gwDir := filepath.Join(tmp, "openshell", "gateways", name) @@ -432,6 +433,7 @@ func TestListGateways_MultipleGateways(t *testing.T) { func TestListGateways_EmptyDirs(t *testing.T) { tmp := t.TempDir() t.Setenv("XDG_CONFIG_HOME", tmp) + t.Setenv(systemGatewayDirEnv, tmp) gateways, err := ListGateways() require.NoError(t, err) @@ -441,6 +443,7 @@ func TestListGateways_EmptyDirs(t *testing.T) { func TestListGateways_ActiveStatus(t *testing.T) { tmp := t.TempDir() t.Setenv("XDG_CONFIG_HOME", tmp) + t.Setenv(systemGatewayDirEnv, tmp) for _, name := range []string{"alpha", "beta"} { gwDir := filepath.Join(tmp, "openshell", "gateways", name) diff --git a/sdk/go/openshell/v1/gateway/paths.go b/sdk/go/openshell/v1/gateway/paths.go index fa0e1373c2..0fa9cb0092 100644 --- a/sdk/go/openshell/v1/gateway/paths.go +++ b/sdk/go/openshell/v1/gateway/paths.go @@ -24,6 +24,10 @@ const ( // systemConfigBase is the system-wide config directory. systemConfigBase = "/etc/openshell" + + // systemGatewayDirEnv overrides the system-wide config root.

Guarded sandbox mutations are sandbox create, provider +attach and detach, sandbox-scoped policy and settings changes, and supervisor +configuration, policy status, and endpoint status reports. Lifecycle paths +(start, stop, delete, restart, supervisor connection and process-exit state, +driver-watch updates, and reconcile) take only a process-local shared global +and exclusive sandbox lock, with no time limit and no mutation advisory lock +(start, restart, and delete also take the SSH identity key below), so only +a global change on the same replica blocks them directly.

Provisioning-deadline expiry also takes +its workspace key locally, so provider and workspace-profile changes on the +same replica can delay it. Each +replica takes its advisory locks on a dedicated lock pool of PostgreSQL +connections, one per guard, 4 by default (gateway config +`database_lock_max_connections`), so at most that many guarded +operations per replica hold or wait for PostgreSQL locks at once. +`openshell_server_mutation_lock_connections_in_use` shows how many are checked +out, against `openshell_server_mutation_lock_connections_capacity`.

It retries lock timeouts there for the first 30 seconds of +that scan, then logs +`tool server endpoint-status startup reconciliation gave up on a sandbox` with +the `sandbox_id` and exits with +`tool server endpoint-status startup reconciliation failed`. A pod that +restarts with that error during a rollout or scale-out is waiting behind a +long holder: find it as above. Those startup timeouts appear in the gateway log +only, because the metrics endpoint starts after the scan. + +A lock connection that PostgreSQL does not open, although at least a second of +the 10-second limit remained, is not a lock timeout. The request fails with +`INTERNAL` and "could not open a mutation lock connection", and the gateway +logs `mutation lock acquisition failed` and increments +`openshell_server_mutation_lock_errors_total` instead of the timeout counter. +A lock statement that fails for another reason, such as a PostgreSQL restart, +is counted the same way. PostgreSQL refused the connection, ran out of +connection slots, was starting up, or did not answer. Check the PostgreSQL logs for "too many +clients already", "remaining connection slots are reserved", or "the database +system is starting up", and compare +`SELECT count(*) FROM pg_stat_activity` with `SHOW max_connections`. Each +replica opens up to its data plus lock pool sizes, 14 with the defaults. + +A gateway log line `timed out returning PostgreSQL mutation lock connection; +discarded connection` means returning a lock session stalled for 5 seconds and +the gateway dropped it; that slot stays busy for up to those 5 seconds. The +warning does not identify the PostgreSQL backend. Healthy guards also hold +idle advisory-lock sessions while validation and writes use separate data +connections. Neither an idle duration nor a matching `client_addr` proves +that a holder is orphaned, even when it blocks a timed-out request. + +Guarded work has no time limit of its own. A holder slowed by a compute +driver, credential backend, middleware, or provider profile source call keeps +its locks until that call returns, and conflicting acquisitions on every +replica time out after 10 seconds. When it releases a lock held longer than +10 seconds, its gateway logs +`mutation lock held longer than the lock wait timeout` with `scope` and +`held_ms`, and `openshell_server_mutation_lock_hold_seconds` records every +hold by scope. Neither reports a hold that is still in progress. Before treating a long-held +advisory lock as orphaned, check the gateway pod at its `client_addr` for +these warnings and for slow dependency calls. A pod that logs them is still +running slow guarded work, so fix that dependency or stop the pod instead of +terminating its lock sessions: + +```bash +kubectl -n openshell logs --since=1h \ + | grep 'mutation lock held longer than the lock wait timeout' +``` + +Before using `SELECT pg_terminate_backend()`, conclusively map that +backend to its owning gateway process and confirm that process has stopped +or can no longer write. If the owner is still running, stop it first and +verify its exit; terminating or failing readiness alone is insufficient. Killing +its lock session while it can still write removes exclusion from an active +mutation. Recheck the backend PID and `backend_start` before terminating the +confirmed orphan: pod IPs and PIDs can be reused, and a database proxy can +hide several gateways behind one `client_addr`. If ownership cannot be +established, investigate connectivity instead of choosing a backend by IP or +idle state. Setting PostgreSQL +`tcp_keepalives_idle`, `tcp_keepalives_interval`, and `tcp_keepalives_count` +(for example 60, 10, and 6) bounds how long such sessions survive. + +If mutations stall or time out while reads and health checks work, inspect +advisory-lock holders and waiters. Do not print the database URI or Secret +contents into logs: ```sql -SELECT pid, granted, waitstart -FROM pg_locks -WHERE locktype = 'advisory'; +SELECT l.pid, l.mode, l.granted, l.waitstart, l.classid, l.objid, + a.client_addr, a.backend_start, a.state, + now() - a.state_change AS in_state_for +FROM pg_locks l +JOIN pg_stat_activity a USING (pid) +WHERE l.locktype = 'advisory' +ORDER BY l.granted, l.waitstart; ``` +Gateways hold these locks at session level outside any transaction, so a +holder (`granted = t`) usually shows `state = idle`. It still holds the lock, +and `in_state_for` approximates how long. `client_addr` is the holding +gateway pod's IP, or the pooler's IP when a connection pooler sits in between. + +The global key appears as `classid = 1330660686` and `objid = 1397247052` +(key `0x4F50454E53484C4C`). Older gateways during a rolling upgrade take that +key exclusively for every guarded mutation, so mutations can queue behind +them until the rollout finishes. + +SSH host identity provisioning and cleanup, in sandbox create, start, +restart, and delete, take one more fleet-wide key, `classid = 1330860872` and +`objid = 1213158228` (key `0x4F535348484F5354`), on a data connection instead +of the lock pool, with a 10-second PostgreSQL `lock_timeout`. Sandbox create +holds its mutation guard while it waits for that key.
