# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Project

Cameleer3 Server — observability server that receives, stores, and serves Camel route execution data and route diagrams from Cameleer3 agents. Pushes config and commands to agents via SSE.

## Related Project

- **cameleer3** (`https://gitea.siegeln.net/cameleer/cameleer3`) — the Java agent that instruments Camel applications
- Protocol defined in `cameleer3-common/PROTOCOL.md` in the agent repo
- This server depends on `com.cameleer3:cameleer3-common` (shared models and graph API)

## Modules

- `cameleer3-server-core` — domain logic, storage, agent registry
- `cameleer3-server-app` — Spring Boot web app, REST controllers, SSE, static resources

## Build Commands

```bash
mvn clean compile          # Compile all modules
mvn clean verify           # Full build with tests
```

## Run

```bash
java -jar cameleer3-server-app/target/cameleer3-server-app-1.0-SNAPSHOT.jar
```

## Key Conventions

- Java 17+ required
- Spring Boot 3.4.3 parent POM
- Depends on `com.cameleer3:cameleer3-common` from Gitea Maven registry
- Jackson `JavaTimeModule` for `Instant` deserialization
- Communication: receives HTTP POST data from agents, serves SSE event streams for config push/commands
- Maintains agent instance registry with states: LIVE → STALE → DEAD
- Storage: PostgreSQL (TimescaleDB) for structured data, OpenSearch for full-text search
- Security: JWT auth with RBAC (AGENT/VIEWER/OPERATOR/ADMIN roles), Ed25519 config signing, bootstrap token for registration
- OIDC: Optional external identity provider support (token exchange pattern). Configured via admin API, stored in database (`server_config` table)
- User persistence: PostgreSQL `users` table, admin CRUD at `/api/v1/admin/users`

## CI/CD & Deployment

- CI workflow: `.gitea/workflows/ci.yml` — build → docker → deploy on push to main or feature branches
- Build step skips integration tests (`-DskipITs`) — Testcontainers needs Docker daemon
- Docker: multi-stage build (`Dockerfile`), `$BUILDPLATFORM` for native Maven on ARM64 runner, amd64 runtime
- `REGISTRY_TOKEN` build arg required for `cameleer3-common` dependency resolution
- Registry: `gitea.siegeln.net/cameleer/cameleer3-server` (container images)
- K8s manifests in `deploy/` — Kustomize base + overlays (main/feature), shared infra (PostgreSQL, OpenSearch, Authentik) as top-level manifests
- Deployment target: k3s at 192.168.50.86, namespace `cameleer` (main), `cam-<slug>` (feature branches)
- Feature branches: isolated namespace, PG schema, OpenSearch index prefix; Traefik Ingress at `<slug>-api.cameleer.siegeln.net`
- Secrets managed in CI deploy step (idempotent `--dry-run=client | kubectl apply`): `cameleer-auth`, `postgres-credentials`, `opensearch-credentials`
- K8s probes: server uses `/api/v1/health`, PostgreSQL uses `pg_isready`, OpenSearch uses `/_cluster/health`
- Docker build uses buildx registry cache + `--provenance=false` for Gitea compatibility
