The only difference +is the `baseurl` in the Lacuna config and that the ForceField key lives in +your secrets store of choice. + +## Notes & caveats + +- **OpenAI and Anthropic are both BYOK.** ForceField's gateway exposes + `/v1/chat/completions` (OpenAI-compatible, BYOK by default) and + `/v1/messages` (Anthropic-native passthrough with SSE streaming and + inline PII redaction). The Lacuna config in this example declares both + providers and routes by URL prefix: `/forcefield-openai/v1/chat/...` + and `/forcefield-anthropic/v1/messages`. +- **ForceField never holds your provider key.** Lacuna sends + `Authorization: Bearer ${OPENAI_API_KEY}` (or `${ANTHROPIC_API_KEY}`) + alongside `x-api-key: ${FORCEFIELD_API_KEY}`. The gateway reads its own + key off `x-api-key`, strips the FF auth headers, and forwards the bearer + untouched to api.openai.com / api.anthropic.com. The provider bill goes + to the key owner, not to ForceField. ForceField's security pipeline + (detectors, PII redaction, output moderation) runs on local models -- no + external LLM cost. +- Bedrock and Gemini ingress on ForceField are not yet implemented. +- **Two-header auth, not one.** Lacuna 0.20.x sets exactly one auth header + per provider via `authorization`. To send both the FF tenant key *and* + the upstream provider key, this example uses `authorization: bearer` + with `apikey: ${PROVIDER_KEY}` and pins + `headers: { "x-api-key": "${FORCEFIELD_API_KEY}" }` as a static header. +- **Model-glob enforcement is provider-dependent.** Lacuna only extracts + the request `model` for Anthropic / Bedrock / Gemini. The OpenAI + chat-completion and responses handlers do not inspect the body, so a + `models: ["gpt-*"]` capability would deny every request. This example + uses `models: ["*"]` for the OpenAI provider; rely on Lacuna's + `capabilities_header` (Tailscale grants) or downstream FF policy to + restrict OpenAI models. +- **Capabilities header is opt-in here.** The default config does not set + `capabilities_header`. Lacuna treats a missing capability header as + `deny_all`, so leaving it on would block every request from clients + that aren't passing through Tailscale grants. Re-enable it (and pass + `Tailscale-App-Capability`) once you are running Lacuna inside a real + tailnet. +- **User attribution.** Lacuna injects `Tailscale-User-Login` upstream + when `identity_header` is set. ForceField records it in its audit trail. +- **Tailscale trust mode is self-host only.** The hosted Cloud Run gateway + cannot use it because Lacuna's egress IP to Cloud Run is not in the + tailnet CGNAT range. Use the `x-api-key` path for SaaS deployments; + Tailscale trust is for ForceField instances co-located with Lacuna in + the tailnet. +- **Defence in depth.** Lacuna's capability filter runs *first*, so + requests blocked at the ACL layer never hit ForceField -- saving + inference cost. Requests that pass Lacuna are then scanned by FF's + detectors and postprocessor. diff --git a/examples/forcefield/claude_code.settings.json b/examples/forcefield/claude_code.settings.json new file mode 100644 index 0000000..d22bdda --- /dev/null +++ b/examples/forcefield/claude_code.settings.json @@ -0,0 +1,7 @@ +{ + "apiKeyHelper": "echo '-'", + "env": { + "ANTHROPIC_BASE_URL": "https://lacuna.flare.ts.net/forcefield-anthropic/", + "ANTHROPIC_AUTH_TOKEN": "-" + } +} diff --git a/examples/forcefield/docker-compose.yml b/examples/forcefield/docker-compose.yml new file mode 100644 index 0000000..d0fb76f --- /dev/null +++ b/examples/forcefield/docker-compose.yml @@ -0,0 +1,35 @@ +services: + lacuna: + image: ghcr.io/flared/lacuna:latest + container_name: lacuna + command: + - "--config" + - "/opt/lacuna-config.json" + - "--host" + - "0.0.0.0" + - "--port" + - "8080" + ports: + - "${LACUNA_HOST_PORT:-8080}:8080" + environment: + # ForceField gateway reachable from inside the container. + # On Docker Desktop (macOS/Windows), host.docker.internal works. + # On Linux, replace with the host's LAN IP or the FF container name + # if you are running everything on the same docker network. + - FORCEFIELD_BASE_URL=${FORCEFIELD_BASE_URL:-http://host.docker.internal:8080} + - FORCEFIELD_API_KEY=${FORCEFIELD_API_KEY:?set FORCEFIELD_API_KEY in .env} + # Upstream provider keys (BYOK).
