Cameleer SaaS — **vendor management plane** for the Cameleer observability stack. Two personas: **vendor** (platform:admin) manages the platform and provisions tenants; **tenant admin** (tenant:manage) manages their observability instance. The vendor creates tenants, which provisions per-tenant cameleer3-server + UI instances via Docker API. No example tenant — clean slate bootstrap, vendor creates everything.
Agent-server protocol is defined in `cameleer3/cameleer3-common/PROTOCOL.md`. The agent and server are mature, proven components — this repo wraps them with multi-tenancy, billing, and self-service onboarding.
-`VendorTenantController.java` — REST at `/api/vendor/tenants` (platform:admin required). List endpoint returns `VendorTenantSummary` with fleet health data (agentCount, environmentCount, agentLimit) fetched in parallel via `CompletableFuture`.
-`AuditService.java` — log audit events (TENANT_CREATE, TENANT_UPDATE, etc.); auto-resolves actor name from Logto when actorEmail is null (cached in-memory)
The SaaS platform is a **vendor management plane**. It does not proxy requests to servers — instead it provisions dedicated per-tenant cameleer3-server instances via Docker API. Each tenant gets isolated server + UI containers with their own database schemas, networks, and Traefik routing.
Server containers join three networks: tenant network (primary), shared services network (`cameleer`), and traefik network. Apps deployed by the server use the tenant network as primary.
**IMPORTANT:** Dynamically-created containers MUST have `traefik.docker.network=cameleer-traefik` label. Traefik's Docker provider defaults to `network: cameleer` (compose-internal name) for IP resolution, which doesn't match dynamically-created containers connected via Docker API using the host network name (`cameleer-saas_cameleer`). Without this label, Traefik returns 504 Gateway Timeout for `/t/{slug}/api/*` paths.
- Tenant isolation enforced by `TenantIsolationInterceptor` (a single `HandlerInterceptor` on `/api/**` that resolves JWT org_id to TenantContext and validates `{tenantId}`, `{environmentId}`, `{appId}` path variables; fail-closed, platform admins bypass)
- 13 OAuth2 scopes on the Logto API resource (`https://api.cameleer.local`): 10 platform scopes + 3 server scopes (`server:admin`, `server:operator`, `server:viewer`), served to the frontend from `GET /platform/api/config`
- Logto Custom JWT (Phase 7b in bootstrap) injects a `roles` claim into access tokens based on org roles and global roles — this makes role data available to the server without Logto-specific code
The server's OIDC config (`OidcConfig`) includes `audience` (RFC 8707 resource indicator) and `additionalScopes`. The `audience` is sent as `resource` in both the authorization request and token exchange, which makes Logto return a JWT access token instead of opaque. The Custom JWT script maps org roles to `roles: ["server:admin"]`.
**CRITICAL:** `additionalScopes` MUST include `urn:logto:scope:organizations` and `urn:logto:scope:organization_roles` — without these, Logto doesn't populate `context.user.organizationRoles` in the Custom JWT script, so the `roles` claim is empty and all users get `defaultRoles` (VIEWER). The server's `OidcAuthController.applyClaimMappings()` uses OIDC token roles (from Custom JWT) as fallback when no DB claim mapping rules exist: claim mapping rules > OIDC token roles > defaultRoles.
The compose stack is: Traefik + traefik-certs (init) + PostgreSQL + ClickHouse + Logto + logto-bootstrap (init) + cameleer-saas. No `cameleer3-server` or `cameleer3-server-ui` in compose — those are provisioned per-tenant by `DockerTenantProvisioner`.
8. Create server container with env vars, Traefik labels (`traefik.docker.network`), health check, Docker socket bind, JAR volume, certs volume (ro)
9. Create UI container with `CAMELEER_API_URL`, `BASE_PATH`, Traefik strip-prefix labels
10. Wait for health check (`/api/v1/health`, not `/actuator/health` which requires auth)
11. Push license token to server via M2M API
12. Push OIDC config (Traditional Web App credentials + `additionalScopes: [urn:logto:scope:organizations, urn:logto:scope:organization_roles]`) to server for SSO
13. Update tenant status -> ACTIVE (or set `provisionError` on failure)
**Server restart** (available to vendor + tenant admin):
-`POST /api/vendor/tenants/{id}/restart` (vendor) and `POST /api/tenant/server/restart` (tenant)
- Calls `TenantProvisioner.stop(slug)` then `start(slug)` — restarts server + UI containers only
-`cameleer-runtime-base` — base image for deployed apps (agent JAR + JRE). CI downloads latest agent SNAPSHOT from Gitea Maven registry. Uses `CAMELEER_SERVER_URL` env var (not CAMELEER_EXPORT_ENDPOINT).
-`docker-compose.dev.yml` — exposes ports for direct access, sets `SPRING_PROFILES_ACTIVE: dev`, `VENDOR_SEED_ENABLED: true`. Volume-mounts `./ui/dist` into the container so local UI builds are served without rebuilding the Docker image (`SPRING_WEB_RESOURCES_STATIC_LOCATIONS` overrides classpath). Adds Docker socket mount for tenant provisioning.
This project is indexed by GitNexus as **cameleer-saas** (2436 symbols, 5282 relationships, 204 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.
> If any GitNexus tool warns the index is stale, run `npx gitnexus analyze` in terminal first.
## Always Do
- **MUST run impact analysis before editing any symbol.** Before modifying a function, class, or method, run `gitnexus_impact({target: "symbolName", direction: "upstream"})` and report the blast radius (direct callers, affected processes, risk level) to the user.
- **MUST run `gitnexus_detect_changes()` before committing** to verify your changes only affect expected symbols and execution flows.
- **MUST warn the user** if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
- When exploring unfamiliar code, use `gitnexus_query({query: "concept"})` to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
- When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use `gitnexus_context({name: "symbolName"})`.
## When Debugging
1.`gitnexus_query({query: "<error or symptom>"})` — find execution flows related to the issue
2.`gitnexus_context({name: "<suspect function>"})` — see all callers, callees, and process participation
3.`READ gitnexus://repo/cameleer-saas/process/{processName}` — trace the full execution flow step by step
4. For regressions: `gitnexus_detect_changes({scope: "compare", base_ref: "main"})` — see what your branch changed
## When Refactoring
- **Renaming**: MUST use `gitnexus_rename({symbol_name: "old", new_name: "new", dry_run: true})` first. Review the preview — graph edits are safe, text_search edits need manual review. Then run with `dry_run: false`.
- **Extracting/Splitting**: MUST run `gitnexus_context({name: "target"})` to see all incoming/outgoing refs, then `gitnexus_impact({target: "target", direction: "upstream"})` to find all external callers before moving code.
- After any refactor: run `gitnexus_detect_changes({scope: "all"})` to verify only expected files changed.
## Never Do
- NEVER edit a function, class, or method without first running `gitnexus_impact` on it.
- NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
- NEVER rename symbols with find-and-replace — use `gitnexus_rename` which understands the call graph.
- NEVER commit changes without running `gitnexus_detect_changes()` to check affected scope.
Before completing any code modification task, verify:
1.`gitnexus_impact` was run for all modified symbols
2. No HIGH/CRITICAL risk warnings were ignored
3.`gitnexus_detect_changes()` confirms changes match expected scope
4. All d=1 (WILL BREAK) dependents were updated
## Keeping the Index Fresh
After committing code changes, the GitNexus index becomes stale. Re-run analyze to update it:
```bash
npx gitnexus analyze
```
If the index previously included embeddings, preserve them by adding `--embeddings`:
```bash
npx gitnexus analyze --embeddings
```
To check whether embeddings exist, inspect `.gitnexus/meta.json` — the `stats.embeddings` field shows the count (0 means no embeddings). **Running analyze without `--embeddings` will delete any previously generated embeddings.**
