"""Automated deployment script for LeoCRM via Coolify API.

═══════════════════════════════════════════════════════════════════════
CURRENT WORKFLOW — Single docker-compose Stack
═══════════════════════════════════════════════════════════════════════

All 4 containers (postgres, redis, crm_app, crm_worker) run in a single
docker-compose stack managed by one Coolify Application.

  deploy.py --initial   →  Create the docker-compose application from scratch
                             (private-deploy-key + PATCH to dockercompose).
                             Two-phase: first deploy without domain, then set
                             docker_compose_domains and redeploy.

  deploy.py              →  Redeploy existing application via /api/v1/deploy.

  deploy.py --verify-only  →  Run verification checks only.

No separate Coolify services for worker/db/redis.  Everything is in one
stack so containers share a network and can reach each other by DNS.
═══════════════════════════════════════════════════════════════════════

Usage:
    python scripts/deploy.py                  # Redeploy via Coolify API
    python scripts/deploy.py --skip-build     # Skip build, just restart
    python scripts/deploy.py --initial        # Create all resources from scratch
    python scripts/deploy.py --verify-only    # Only run verification

Environment variables:
    COOLIFY_API_TOKEN    — Coolify API token (required)
    COOLIFY_BASE_URL     — Coolify base URL (default: https://server.media-on.de)
    COOLIFY_APP_UUID     — Application UUID (optional, resolved via API if absent)
    APP_NAME             — Application name for API lookup (default: derived from APP_DOMAIN)
    APP_DOMAIN           — App domain for health/FQDN (required, e.g. https://crm.media-on.de)
    SSH_KEY              — SSH key path for verification (default: /a0/usr/workdir/.ssh/coolify-01-root)
    SERVER_IP            — Server IP for SSH verification (default: 46.225.91.159)
    LOGIN_EMAIL          — Login test email (optional, for verification)
    LOGIN_PASSWORD       — Login test password (optional, for verification)

    Secrets (required for --initial):
    DB_PASSWORD          — PostgreSQL password for all roles
    REDIS_PASSWORD       — Redis password
    SECRET_KEY           — Application secret key

    Initial deploy only:
    COOLIFY_PROJECT_UUID     — Coolify project UUID
    COOLIFY_SERVER_UUID      — Coolify server UUID
    COOLIFY_PRIVATE_KEY_UUID — Coolify private deploy key UUID
    COOLIFY_ENVIRONMENT      — Coolify environment name (default: production)

Exit codes:
    0 — deployment successful
    1 — deployment failed
    2 — configuration error

    ARCHITEKTUR: Einzelner docker-compose Stack (NICHT 4 separate Ressourcen!)
    ─────────────────────────────────────────────────────────────────────
    Dieses Script erstellt EINE Coolify Application mit build_pack=dockercompose.
    Coolify liest docker-compose.yaml aus dem Git-Repo und baut alle 4 Container
    (postgres, redis, crm_app, crm_worker) in einem gemeinsamen Stack.

    ❌ NICHT tun:
    - 4 separate Coolify Ressourcen erstellen (Services für PG/Redis, Application
      für API, Service für Worker). Das funktioniert NICHT weil Coolify jedem
      Service ein eigenes Docker-Netzwerk gibt. Die Container können sich nicht
      per DNS erreichen → socket.gaierror: Temporary failure in name resolution.
    - connect_to_docker_network=True setzen. Coolify kümmert sich selbst um das
      Netzwerk innerhalb eines docker-compose Stacks.
    - :443 an die Domain anhängen (z.B. https://crm.media-on.de:443). Das führt
      zu leeren Host() Traefik-Labels → 503 Fehler. Siehe unten.
    - docker-compose.yml (mit .yml) verwenden. Coolify sucht docker-compose.yaml
      (mit .yaml). Falsche Dateiendung → "Docker Compose file not found" Fehler.
    - Service-Namen mit Bindestrich verwenden (crm-app, crm-worker). Coolify
      konvertiert Bindestriche zu Unterstrichen in docker_compose_domains. Die
      DB zeigt dann crm_app aber die docker-compose.yaml hat crm-app → kein
      Match → keine Traefik-Labels → 503. Verwende Unterstriche: crm_app,
      crm_worker.

    ✅ RICHTIG:
    - Service-Namen mit Unterstrichen: crm_app, crm_worker, postgres, redis
    - docker-compose.yaml (mit .yaml, nicht .yml)
    - 2-Phase Deploy: Erster Deploy OHNE Domain, dann docker_compose_domains
      setzen, dann Redeploy. Grund: Coolify muss zuerst die docker-compose.yaml
      aus dem Git-Repo lesen um die Service-Namen zu kennen. Erst dann kann
      docker_compose_domains korrekt zugeordnet werden.
    - docker_compose_domains Format: [{"name": "crm_app", "domain": "https://crm.media-on.de"}]
      WICHTIG: KEIN :443 am Ende! Das :443 führt zu leeren Host() Labels.
    - SERVICE_FQDN_CRM_APP_8000 in docker-compose.yaml environment block für
      automatische Domain-Konfiguration durch Coolify Magic ENV.

    FUNKTIONIERENDE BEISPIEL-APP: hms-licht-ton (UUID wvus7va5u0f9dmg27ggca7rl)
    - docker_compose_domains: {"frontend":{"domain":"https://hms.media-on.de"}}
    - Container hat Traefik-Labels: Host(`hms.media-on.de`)
    - Kein :443, Service-Name ohne Bindestrich

    MEHRERE INSTANZEN:
    - APP_NAME und APP_DOMAIN als ENV-Variablen setzen
    - Alles andere wird automatisch konfiguriert
    - Beispiel: APP_NAME=leocrm-test APP_DOMAIN=https://crm-test.media-on.de
