Deterministic Port Registry

All Stella Ops web services are assigned deterministic HTTPS/HTTP port pairs to avoid collisions during local development and simplify service discovery configuration.

Port Assignment Scheme

  • Formula: Service at slot N → HTTPS = 10000 + N×10, HTTP = 10000 + N×10 + 1
  • Range: 10000–10911
  • Local alias: Each service additionally binds https://{name}.stella-ops.local (port 443) and http://{name}.stella-ops.local (port 80) — no port in URL

Worker Services

Worker services associated with a web service use ports offset by +2/+3 from the web service slot:

HTTPS HTTP Service Path
10062 10063 EvidenceLocker Worker src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Worker
10162 10163 RiskEngine Worker src/RiskEngine/StellaOps.RiskEngine/StellaOps.RiskEngine.Worker
10172 10173 Orchestrator Worker src/Orchestrator/StellaOps.Orchestrator/StellaOps.Orchestrator.Worker
10182 10183 TaskRunner Worker src/TaskRunner/StellaOps.TaskRunner/StellaOps.TaskRunner.Worker
10232 10233 TimelineIndexer Worker src/TimelineIndexer/StellaOps.TimelineIndexer/StellaOps.TimelineIndexer.Worker
10282 10283 Notifier Worker src/Notifier/StellaOps.Notifier/StellaOps.Notifier.Worker
10342 10343 PacksRegistry Worker src/PacksRegistry/StellaOps.PacksRegistry/StellaOps.PacksRegistry.Worker
10402 10403 ExportCenter Worker src/ExportCenter/StellaOps.ExportCenter/StellaOps.ExportCenter.Worker

Environment Variable Convention

Each web service has a corresponding STELLAOPS_{SERVICE}_URL environment variable. The Platform service reads these at startup (Layer 1 of the 3-layer configuration) and maps them into ApiBaseUrls for the Angular frontend.

Example: STELLAOPS_SCANNER_URL=https://scanner.internal:10080 maps to ApiBaseUrls["scanner"].

See also: 3-Layer Service URL Configuration

Friendly Hostnames (.stella-ops.local)

Each service can be reached via https://{name}.stella-ops.local (port 443) and http://{name}.stella-ops.local (port 80) — no port in the URL. The HTTPS/HTTP dev ports (10000+) are bound to localhost only; the .stella-ops.local hostnames use standard ports.

Each hostname resolves to a unique loopback IP (127.1.0.x) so every service can bind ports 443/80 simultaneously without collisions. The entire 127.0.0.0/8 range is loopback on all platforms, so 127.1.0.x addresses work the same as 127.0.0.1.

The Angular UI (ng serve) binds to https://stella-ops.local (port 443 on 127.1.0.1).

At startup each service resolves its hostname to its dedicated loopback IP and binds ports 443/80 on that IP. It logs the result:

  • Resolves, ports free: INFO Also accessible at https://{name}.stella-ops.local and http://{name}.stella-ops.local
  • Resolves, ports taken: INFO Hostname {name}.stella-ops.local resolves but ports 443/80 are unavailable; use the dev port instead.
  • Does not resolve: WARN Hostname {name}.stella-ops.local does not resolve. To enable friendly .stella-ops.local URLs, add hosts-file entries as described in docs/technical/architecture/port-registry.md.

Hosts file setup

Each service gets a unique loopback IP in the 127.1.0.x range so ports 443/80 never collide.

Add the following to your hosts file (C:\Windows\System32\drivers\etc\hosts on Windows, /etc/hosts on Linux/macOS):

# Stella Ops local development hostnames
# Each service gets a unique loopback IP so all can bind :443/:80 simultaneously.

Infrastructure containers (databases, caches, object storage, transparency logs) use a separate loopback range (127.1.1.x) to avoid collisions with application services.
