## Quick Reference

| Environment | URL | Server | SSH Alias | Container | Image Tag | Port | DB Name |
|-------------|-----|--------|-----------|-----------|-----------|------|---------|
| **Production** | `pd.manticorum.com/api` | akamai (172.237.147.99) | `akamai` | `pd_api` | `:latest` | 8002 | `pd_master` |
| **Dev** | `pddev.manticorum.com/api` | pd-database (10.10.0.42) | `pd-database` | `dev_pd_database` | `:dev` | 813 | `paperdynasty_dev` |

**API Token** (both envs): `Tp3aO3jhYve5NJF1IqOmJTmk`

## SSH Access

```bash
# Dev server (all these aliases work)
ssh pd-database    # or: sba-db, strat-database, pd-db, strat-db, sba-database
# → 10.10.0.42, user: cal

# Prod server
ssh akamai         # or: akamai-nano
# → 172.237.147.99, user: root
```

## Dev Server Operations

### Container Management

```bash
# Check status
ssh pd-database "docker ps --filter name=dev_pd_database --format '{{.Names}}\t{{.Image}}\t{{.Status}}'"

# View logs (stdout/stderr)
ssh pd-database "docker logs dev_pd_database --tail 100"
ssh pd-database "docker logs dev_pd_database -f --tail 50"  # follow

# View application logs (file-based, by date)
ssh pd-database "cat /home/cal/container-data/dev-pd-database/logs/database/$(date +%Y-%-m-%-d).log"
```

### Deploy New Dev Image

The CI pipeline pushes `manticorum67/paper-dynasty-database:dev` on PR builds to main.

```bash
# Standard deploy (compose file already uses :dev tag)
ssh pd-database "cd /home/cal/container-data/dev-pd-database && docker compose pull && docker compose up -d"
```

**If the container name conflicts** (orphaned from previous non-compose run):
```bash
ssh pd-database "docker stop dev_pd_database && docker rm dev_pd_database && cd /home/cal/container-data/dev-pd-database && docker compose up -d"
```

### Health Check

```bash
# Quick status code check
curl -sL -o /dev/null -w "%{http_code}" "https://pddev.manticorum.com/api/v2/players/?limit=1" \
  -H "Authorization: Bearer Tp3aO3jhYve5NJF1IqOmJTmk"

# Time a card render (fresh, no cache)
curl -sL -o /dev/null -w "HTTP %{http_code} | Total: %{time_total}s | TTFB: %{time_starttransfer}s\n" \
  "https://pddev.manticorum.com/api/v2/players/12726/battingcard?d=$(date +%Y-%m-%d-%s)"

# Test HTML card render
# Append &html=true for HTML output (useful for debugging card layout)
curl -sL "https://pddev.manticorum.com/api/v2/players/12726/battingcard?d=$(date +%Y-%m-%d)&html=true"
```

### File System Layout

```
/home/cal/container-data/dev-pd-database/
├── docker-compose.yml              # Compose config
├── storage/                        # Mounted → /usr/src/app/storage
│   ├── templates/                  # HTML card templates (style.html, player_card.html)
│   ├── cards/                      # Cached rendered card PNGs
│   │   └── cardset-{id}/
│   │       ├── batting/            # {player_id}-{date}-v{variant}.png
│   │       └── pitching/

└── logs/
    └── database/
        └── {YYYY}-{M}-{D}.log     # Application logs (date format: no zero-padding)
```

### Clear Card Cache (Force Re-render)

```bash
# Clear specific player
ssh pd-database "rm -f /home/cal/container-data/dev-pd-database/storage/cards/cardset-27/batting/12726-*.png"

# Clear all cached cards for a cardset
ssh pd-database "rm -rf /home/cal/container-data/dev-pd-database/storage/cards/cardset-27/"

# Alternative: use cache-busting query param (changes the ?d= value)
curl -sL "https://pddev.manticorum.com/api/v2/players/12726/battingcard?d=2026-3-13-$(date +%s)"
```

### Database Access

Dev uses `paperdynasty_dev` on the shared `sba_postgres` container (same server, port 5432).

```bash
# Direct psql
ssh pd-database "docker exec -it sba_postgres psql -U sba_admin -d paperdynasty_dev"

# Adminer web UI
# http://10.10.0.42:8080
# Server: sba_postgres | User: sba_admin | Password: your_production_password | DB: paperdynasty_dev

# Quick query
ssh pd-database "docker exec sba_postgres psql -U sba_admin -d paperdynasty_dev -c 'SELECT count(*) FROM player WHERE cardset_id = 27'"
```

## Production Server Operations

### Container Management

```bash
# Check status
ssh akamai "docker ps --filter name=pd_api --format '{{.Names}}\t{{.Image}}\t{{.Status}}'"

# View logs
ssh akamai "docker logs pd_api --tail 100"
```

### Deploy to Production

Production uses `:latest` tag. After merging to main, CI pushes both `:latest` and a CalVer tag.

```bash
ssh akamai "cd /root/container-data/paper-dynasty && docker compose pull && docker compose up -d"
```

### File System Layout (Prod)

```
/root/container-data/paper-dynasty/
├── docker-compose.yml
├── storage/                        # Card cache, templates, scouting data
│   └── cards/cardset-{id}/...
└── logs/
    └── database/
```

### Database Access (Prod)

Production uses `pd_master` database with `pd_admin` user on the shared `sba_postgres` on akamai.

```bash
ssh akamai "docker exec -it sba_postgres psql -U pd_admin -d pd_master"
```

## Docker Image Tags

| Tag | Source | When Pushed | Use |
|-----|--------|-------------|-----|
| `:latest` | `main` branch merge | On merge to main | Production |
| `:dev` | PR to `main` | On PR creation/update | Dev testing |
| `:YYYY.MM.BUILD` | `main` branch merge | On merge to main | Versioned releases |
| `:rc-SHA` | `next-release` push | On push to next-release | Release candidates |

CI pipeline: `.gitea/workflows/build.yml` in `paper-dynasty-database` repo.

## Docker Compose Config (Dev)

```yaml
services:
  database:
    image: manticorum67/paper-dynasty-database:dev
    restart: unless-stopped
    container_name: dev_pd_database
    volumes:
      - ./storage:/usr/src/app/storage
      - ./logs:/usr/src/app/logs
    ports:
      - 813:80
    environment:
      - TESTING=True
      - LOG_LEVEL=INFO
      - API_TOKEN=Tp3aO3jhYve5NJF1IqOmJTmk
      - TZ=America/Chicago
      - WORKERS_PER_CORE=1.0
      - PRIVATE_IN_SCHEMA=TRUE
      - DATABASE_TYPE=postgresql
      - POSTGRES_DB=paperdynasty_dev
      - POSTGRES_USER=sba_admin
      - POSTGRES_PASSWORD=your_production_password
      - POSTGRES_HOST=sba_postgres
      - POSTGRES_PORT=5432
networks:
  default:
    external:
      name: dev-sba-database_default
```

**Key differences from prod:**
- `TESTING=True` (enables private endpoints in schema)
- `PRIVATE_IN_SCHEMA=TRUE` (shows all endpoints in Swagger)
- `WORKERS_PER_CORE=1.0` (fewer workers than prod's 1.5)
- No healthcheck configured (prod has one)
- No `WORKER_TIMEOUT` set (prod uses 180s)

## Networking

- **Dev**: Joins `dev-sba-database_default` network to reach `sba_postgres` on the same host
- **Prod**: Joins both `sba-database_default` (for postgres) and `nginx-proxy-manager_npm_network` (for reverse proxy) on akamai
- **DNS**: `pd.manticorum.com` → Cloudflare → akamai:8002; `pddev.manticorum.com` → local DNS → 10.10.0.42:813

## Troubleshooting

### Container won't start (name conflict)

```
Error: container name "/dev_pd_database" is already in use
```

The old container was started outside compose tracking. Remove it manually:
```bash
ssh pd-database "docker stop dev_pd_database; docker rm dev_pd_database"
ssh pd-database "cd /home/cal/container-data/dev-pd-database && docker compose up -d"
```

### Card renders return 502

Usually means Chromium crashed inside the container. Check logs and restart:
```bash
ssh pd-database "docker logs dev_pd_database --tail 20"
ssh pd-database "cd /home/cal/container-data/dev-pd-database && docker compose restart"
```

With the persistent browser (Phase 0), `get_browser()` auto-reconnects on the next request. If it persists, the container may need more memory (Chromium needs ~100MB per page).

### Application logs missing for today

Log files use non-zero-padded date format: `2026-3-13.log` not `2026-03-13.log`.

```bash
# Correct
ssh pd-database "cat /home/cal/container-data/dev-pd-database/logs/database/$(date +%Y-%-m-%-d).log"
```

### Database connection errors

Verify the postgres container is running and the network is correct:
```bash
ssh pd-database "docker ps --filter name=sba_postgres"
ssh pd-database "docker exec dev_pd_database ping -c1 sba_postgres"
```

### Stale card images (old render showing)

Cards are cached as PNG files on disk. Either delete the file or use a new `?d=` cache-buster value:
```bash
# Option 1: Delete cached file
ssh pd-database "rm /home/cal/container-data/dev-pd-database/storage/cards/cardset-27/batting/12726-*.png"

# Option 2: Use different date param (generates new file, old one remains)
curl "https://pddev.manticorum.com/api/v2/players/12726/battingcard?d=2026-3-13-$(date +%s)"
```
