| + | # P2-5a: Wildcard DNS Infrastructure |
| + | |
| + | ## Status: Complete |
| + | |
| + | ## Branch |
| + | `feat/P2-5a-wildcard-infra` (from `phase-2`) |
| + | |
| + | ## Changes |
| + | - **`infra/__main__.py`**: Added a second `DnsComponent` instance for `*.wikibot.io` |
| + | - No changes to `infra/components/dns.py` — the existing component already supports wildcard domains |
| + | |
| + | ## New Resources (7) |
| + | | Resource | Type | |
| + | |----------|------| |
| + | | `wildcard` | DnsComponent (parent) | |
| + | | `wildcard-cert` | ACM Certificate for `*.wikibot.io` | |
| + | | `wildcard-cert-validation` | Route 53 CNAME for DNS validation | |
| + | | `wildcard-cert-validated` | ACM CertificateValidation | |
| + | | `wildcard-domain` | API Gateway v2 DomainName | |
| + | | `wildcard-mapping` | API Gateway v2 ApiMapping | |
| + | | `wildcard-dns` | Route 53 A record (alias to API Gateway) | |
| + | |
| + | ## Verification |
| + | - `pulumi preview` passes: +7 to create, 65 unchanged |
| + | - `dev.wikibot.io` resources untouched |
| + | - New export: `wildcard_domain_url` = `https://*.wikibot.io` |
| + | |
| + | ## Design Notes |
| + | - Separate cert for wildcard (not modifying dev cert) — simplest approach, avoids risk to existing setup |
| + | - Wildcard A record + API mapping both point to the existing `otterwiki_apigw` API Gateway and stage |
| + | - Multi-tenant routing (`username.wikibot.io`) will be handled at the application layer (P2-5b) |
