# ADR-009: Nginx Edge with Automatic Tenant SSL Expansion

## Context
Tenant subdomains (`*.torbatyar.ir`) and custom domains need HTTPS. Manual cert issuance does not scale with self-service onboarding.
## Decision
Nginx terminates TLS on the edge host. Let's Encrypt certificate for the platform is expanded for new tenant hostnames via `provision_ssl.py`, triggered by Core Celery over SSH when domains are provisioned. Map file `torbatyar-tenant-ssl.map` controls HTTPS redirect readiness per tenant host.
## Consequences
### Positive
- Self-service subdomain HTTPS
- Centralized edge routing for FE, Core, Identity, Keycloak
### Negative
- Worker must reach nginx host over SSH
- Cert expand rate limits and LE constraints apply
## Alternatives Considered
1. Traefik with built-in ACME
2. Cloudflare proxy-only TLS
