From 5a030d053a549ea7fe24978947d276c09c55375d Mon Sep 17 00:00:00 2001 From: itdove Date: Mon, 6 Apr 2026 17:20:37 -0400 Subject: [PATCH 01/31] feat(providers): add Vertex AI provider type - Add vertex provider plugin with ANTHROPIC_VERTEX_PROJECT_ID credential - Add vertex inference profile with Anthropic-compatible protocols - Register vertex in provider registry and CLI - Add vertex to supported inference provider types - Fix scripts/podman.env to use correct env var names for local registry - Update docs for simplified CLI install workflow Known limitation: GCP OAuth authentication not yet implemented.

This commit fixes two issues: 1. docker-build-image.sh: Filter out --push flag and execute push as separate command after build completes 2. docker-publish-multiarch.sh: Use safe array expansion syntax to avoid unbound variable errors with set -u when EXTRA_TAGS is empty Note: Multi-arch builds with Podman still require manual workflow due to cross-compilation toolchain issues. Use /tmp/build-multiarch-local.sh for local multi-arch builds with QEMU emulation.

The solution uses the existing sandbox proxy to intercept and inject Authorization headers with OAuth tokens. Architecture: - Gateway: Exchanges ADC refresh_token for OAuth access_token via token cache with automatic refresh (300s before expiry) - Sandbox proxy: Intercepts fake ADC OAuth exchange and injects real OAuth tokens into Vertex AI API requests via Authorization headers - No credential files written to disk (fake ADC auto-created in sandbox) Key changes: Provider infrastructure: - Add TokenCache for automatic OAuth token refresh with configurable margin - Add SecretStore trait and DatabaseSecretStore for credential storage - Add RuntimeError types for OAuth token exchange failures - Add generic provider runtime types (TokenResponse, RuntimeResult) Vertex provider (crates/openshell-providers/src/providers/vertex.rs): - Validate ADC credentials on discovery via OAuth token exchange test - Implement get_runtime_token() to exchange refresh_token for access_token - Remove OAuth token storage (tokens now ephemeral in TokenCache) Gateway (crates/openshell-server/src/grpc.rs): - Add TokenCache to gateway state for automatic token refresh - Inject VERTEX_ACCESS_TOKEN via SecretResolver (not environment) - Keep VERTEX_ADC as direct injection for fake file creation - Add config values to sandbox environment (PROJECT_ID, REGION) Sandbox proxy (crates/openshell-sandbox/src/l7/rest.rs): - Add is_vertex_api_request() to detect regional/global Vertex endpoints (matches *-aiplatform.googleapis.com and aiplatform.googleapis.com) - Add inject_vertex_auth_header() to inject Authorization: Bearer headers - Add get_vertex_access_token() to resolve token from SecretResolver - Intercept fake ADC OAuth exchange, return fake success to CLI Sandbox init (crates/openshell-sandbox/src/lib.rs): - Auto-create fake ADC file at ~/.config/gcloud/application_default_credentials.json - Set correct ownership and permissions (600) for sandbox user Sandbox secrets (crates/openshell-sandbox/src/secrets.rs): - Remove VERTEX_ACCESS_TOKEN from direct injection list - Token now accessible via SecretResolver for proxy injection Policy (examples/vertex-ai/sandbox-policy.yaml): - Add protocol: rest and access: full to all Vertex AI endpoints - Enable L7 HTTP inspection for Authorization header injection - Add PyPI network policy with UV Python resolved symlink paths - Add commented oauth_credentials section for future configuration Build (deploy/docker/Dockerfile.images): - Disable cargo-target and sccache cache mounts (commented with explanation) - Prevents stale builds where code changes don't appear in binaries - BuildKit persists these caches across all cleanup operations Protobuf: - Add OAuthCredentialsPolicy message for future per-sandbox config - Add optional oauth_credentials field to SandboxPolicy Documentation: - Add OAUTH_PROVIDERS.md with guide for adding new OAuth providers - Update Podman debugging section in AGENTS.md - Update Vertex AI README with ADC setup instructions Testing: - Verified end-to-end flow with regional endpoints (us-east5) - Verified fake ADC file auto-creation with correct ownership - Verified OAuth token injection into Authorization headers - Verified token auto-refresh in gateway token cache --- AGENTS.md | 60 ++ Cargo.lock | 8 + Cargo.toml | 6 + crates/openshell-policy/src/lib.rs | 42 +- crates/openshell-providers/Cargo.toml | 9 + crates/openshell-providers/src/lib.rs | 37 +- .../src/providers/vertex.rs | 235 ++++++- crates/openshell-providers/src/runtime.rs | 62 ++ .../openshell-providers/src/secret_store.rs | 56 ++ .../src/stores/database.rs | 82 +++ crates/openshell-providers/src/stores/mod.rs | 8 + crates/openshell-providers/src/token_cache.rs | 313 +++++++++ crates/openshell-sandbox/src/l7/rest.rs | 150 ++++- crates/openshell-sandbox/src/lib.rs | 83 +++ crates/openshell-sandbox/src/opa.rs | 4 + crates/openshell-sandbox/src/proxy.rs | 30 +- crates/openshell-sandbox/src/secrets.rs | 9 +- crates/openshell-server/Cargo.toml | 1 + crates/openshell-server/src/grpc.rs | 326 +++++++++- crates/openshell-server/src/lib.rs | 6 + deploy/docker/Dockerfile.images | 7 +- examples/vertex-ai/OAUTH_PROVIDERS.md | 302 +++++++++ examples/vertex-ai/README.md | 599 ++++++++++++++++-- examples/vertex-ai/sandbox-policy.yaml | 60 +- proto/openshell.proto | 26 + proto/sandbox.proto | 18 + 26 files changed, 2419 insertions(+), 120 deletions(-) create mode 100644 crates/openshell-providers/src/runtime.rs create mode 100644 crates/openshell-providers/src/secret_store.rs create mode 100644 crates/openshell-providers/src/stores/database.rs create mode 100644 crates/openshell-providers/src/stores/mod.rs create mode 100644 crates/openshell-providers/src/token_cache.rs create mode 100644 examples/vertex-ai/OAUTH_PROVIDERS.md diff --git a/AGENTS.md b/AGENTS.md index ee1fd03cc..51d588895 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -100,6 +100,66 @@ These pipelines connect skills into end-to-end workflows.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace Vertex-specific hardcoded OAuth logic with generic, policy-configurable header injection mechanism. Any OAuth provider (AWS Bedrock, Azure OpenAI, etc.) can now configure header injection via sandbox policy. Breaking changes: - Removed is_vertex_api_request() hardcoded hostname detection - Removed inject_vertex_auth_header() Vertex-specific function - OAuth header injection now requires policy configuration Protocol changes: - Added OAuthInjectionConfig message to sandbox.proto - Added oauth field to NetworkEndpoint message - Fields: token_env_var (required), header_format (default: "Bearer {token}") Implementation: - Generic inject_oauth_header() replaces provider-specific logic - Proxy reads oauth config from endpoint policy via OPA - Policy-driven token resolution via SecretResolver - OAuth config serialized to Rego data for L7 module access - Thread oauth_config through L7EvalContext to relay functions YAML parsing: - Added OAuthInjectionConfigDef for policy deserialization - Added oauth field to NetworkEndpointDef - Round-trip serialization/deserialization support - Added comprehensive policy parsing tests (3 new tests) Example policy configuration: ```yaml network_policies: vertex: endpoints: - host: aiplatform.googleapis.com port: 443 protocol: rest oauth: token_env_var: VERTEX_ACCESS_TOKEN header_format: "Bearer {token}" ``` Proxy behavior: 1. Intercepts requests matching endpoint host:port 2. Reads oauth config from policy 3. Fetches token from environment variable or SecretResolver 4. Injects Authorization header using configured format 5. Proxy fetches fresh tokens from gateway TokenCache on each request Documentation: - Updated Vertex AI README with proxy-driven refresh architecture - Updated example policy with OAuth configuration - Clarified token flow: Gateway → TokenCache → Proxy → Header Tests: 41/41 policy tests passing, 199/199 server tests passing --- crates/openshell-policy/src/lib.rs | 102 ++++++- crates/openshell-sandbox/src/grpc_client.rs | 2 +- crates/openshell-sandbox/src/l7/mod.rs | 35 +++ crates/openshell-sandbox/src/l7/relay.rs | 14 +- crates/openshell-sandbox/src/l7/rest.rs | 76 ++--- crates/openshell-sandbox/src/opa.rs | 6 + crates/openshell-sandbox/src/proxy.rs | 4 +- examples/vertex-ai/README.md | 308 +++++++++++++------- examples/vertex-ai/sandbox-policy.yaml | 24 +- proto/sandbox.proto | 18 ++ 10 files changed, 437 insertions(+), 152 deletions(-) diff --git a/crates/openshell-policy/src/lib.rs b/crates/openshell-policy/src/lib.rs index fc800e2bc..3545a67d0 100644 --- a/crates/openshell-policy/src/lib.rs +++ b/crates/openshell-policy/src/lib.rs @@ -16,7 +16,8 @@ use std::path::Path;
