monxas.casa — apex landing
cors.monxas.casa — utility público (rate-limited)
kiwix.monxas.casa — read-only KB
rag.monxas.casa, loki.monxas.casa — APIs con bearer auth

deploy.monxas.casa, deploy-trip*.monxas.casa — CI/CD webhooks (review caso a caso)

API recipes¶

```bash

Listar apps + policies¶

source ~/.env # CF_API_TOKEN ACC= curl -sH "Authorization: Bearer $CF_API_TOKEN" \ "https://api.cloudflare.com/client/v4/accounts/$ACC/access/apps?per_page=100" | \ jq '.result[] | {domain, name}'

Proteger nueva app (crea + policy default)¶

curl -X POST -H "Authorization: Bearer $CF_API_TOKEN" -H 'Content-Type: application/json' \ --data '{"name":"X","domain":"x.monxas.casa","type":"self_hosted","session_duration":"24h","app_launcher_visible":false}' \ "https://api.cloudflare.com/client/v4/accounts/$ACC/access/apps"

luego copiar app_id de la respuesta y:¶

curl -X POST -H "Authorization: Bearer $CF_API_TOKEN" -H 'Content-Type: application/json' \ --data '{"name":"default","decision":"allow","include":[{"email":{"email":"[email protected]"}},{"email_domain":{"domain":"monxas.com"}}]}' \ "https://api.cloudflare.com/client/v4/accounts/$ACC/access/apps//policies"

Verify external (302 = CF Access OK)¶

curl -s -o /dev/null -w "%{http_code}\n" https://x.monxas.casa/ ```

Identity Provider¶

PocketID está configurado como OIDC IdP en CF Zero Trust. El cliente Cloudflare Access existe en PocketID DB con callback https://monxas.cloudflareaccess.com/cdn-cgi/access/callback.

Cuando hay sesión válida, CF Access pasa el request al origin. Cuando no, redirige a PocketID. Una vez autenticado, regresa a la app. Sesión 24h shared entre todas las apps.

Gotchas¶

App sin policy = BLOQUEA TODO. Crear app y policy en transacción rápida o usar CF dashboard que lo hace junto.
Webhooks/APIs externos: requieren bypass específico por path. Ver patrón n8n/webhook.
Móviles/CLIs (LunaSea, etc.): no soportan OIDC interactivo. Usar Service Tokens (CF API).
Subdomain debe estar en tunnel ingress antes de crear CF Access app, si no, queda inaccesible.
