## Installation

### Prerequisites

- **Python**: 3.10 or higher
- **Docker**: Required for running DOMjudge infrastructure
- **Operating System**: Linux (Ubuntu 22.04 recommended), macOS

### System Requirements (Linux)

Enable **cgroups** for judgehost functionality:

**Ubuntu 22.04:**

1. Create GRUB configuration:
   ```bash
   sudo vi /etc/default/grub.d/99-domjudge-cgroups.cfg
   ```

2. Add this line:
   ```
   GRUB_CMDLINE_LINUX_DEFAULT="cgroup_enable=memory swapaccount=1 systemd.unified_cgroup_hierarchy=0"
   ```

3. Update and reboot:
   ```bash
   sudo update-grub
   sudo reboot
   ```

4. Verify:
   ```bash
   cat /proc/cmdline  # Should show cgroup settings
   ```

### Install

```bash
pip install domjudge-cli
dom --version
```

---

## Quick Start

```bash
# 1. Initialize configuration
dom init

# 2. Deploy infrastructure
dom infra apply

# 3. Create contests with problems and teams
dom contest apply
```

Access DOMjudge at `http://localhost:8080` (or configured port).

---

## ⚠ IMPORTANT: Tool Scope

This tool is designed for **INITIAL SETUP** of DOMjudge infrastructure and contests.

### What This Tool Does ✓

- Deploy DOMjudge infrastructure (Docker containers)
- Create new contests with problems and teams
- Plan changes before applying them
- Scale judgehost count

### What This Tool Does NOT Do ❌

- ❌ **Update existing contests** (DOMjudge API limitation)
- ❌ **Update team/problem data after creation**
- ❌ **Ongoing contest management** (use DOMjudge web UI instead)

**Example:**

```bash
# ✓ Initial setup - Works perfectly
dom init
dom infra apply
dom contest apply

# ❌ Updating existing contest - NOT supported
vim dom-judge.yaml  # Change contest duration
dom contest apply   # ⚠ Warning: Update manually in web UI
```

For ongoing management, use the DOMjudge web interface.

---

  - archive: "problems/fizzbuzz.zip"
    platform: "domjudge"
    color: "blue"
  
  # Polygon format (must be Linux package!)

## Usage Examples

### Complete Setup Workflow

```bash
# 1. Create configuration
dom init

# 2. Review infrastructure plan
dom infra plan

# 3. Deploy infrastructure
dom infra apply

# 4. Verify deployment
dom infra status

# 5. Review contest plan
dom contest plan

# 6. Create contests
dom contest apply

# 7. Verify problems
dom contest verify-problemset "My Contest"
```

### Scaling Judgehosts

```bash
# Edit config to change judge count
vim dom-judge.yaml  # Change judges: 4 -> 8

# Preview changes
dom infra plan  # Shows: Safe judge scaling

# Apply changes (no downtime)
dom infra apply
```

### Complete Teardown

```bash
# Remove infrastructure (keep data)
dom infra destroy --confirm

# Complete removal including data
dom infra destroy --confirm --force-delete-volumes
```

### Health Check Script

```bash
#!/bin/bash
# Check if DOMjudge is healthy

if dom infra status --json > /dev/null 2>&1; then
  echo "✓ DOMjudge is healthy"
  exit 0
else
  echo "✗ DOMjudge has issues"
  exit 1
fi
```

### Multiple Environments

```bash
# Production
dom infra apply -f production.yaml
dom contest apply -f production.yaml

# Staging
dom infra apply -f staging.yaml
dom contest apply -f staging.yaml
```

---

## Troubleshooting

### Infrastructure Issues

**Problem:** Containers won't start

```bash
# Check Docker daemon
docker ps

# Check logs
docker logs domjudge-cli-domserver

# Verify cgroups (Linux)
cat /proc/cmdline
```

**Problem:** Port already in use

```bash
# Change port in config
vim dom-judge.yaml  # Change port: 8080 -> 9090

# Destroy and redeploy
dom infra destroy --confirm
dom infra apply
```

**Problem:** Judgehosts not running

```bash
# Check status
dom infra status

# View logs
docker logs domjudge-cli-judgehost-1

# Verify cgroups configuration
```

### Contest Issues

**Problem:** Problems fail to upload

```bash
# Verify problem package format
# Must have problem.yaml and data/ directory

# Check logs
dom contest apply --verbose
```

**Problem:** Team creation fails

```bash
# Check team data format
# Name, affiliation, country required

# Use verbose mode
dom contest apply --verbose
```

**Problem:** "Contest already exists" warning

This is expected when trying to update contest fields. The tool can only CREATE contests, not update them. Use DOMjudge web UI for updates.

### General Issues

**Problem:** Configuration validation fails

```bash
# Inspect parsed config
dom contest inspect

# Check YAML syntax
# Ensure proper indentation and structure
```

**Problem:** Docker permission denied

```bash
# Add user to docker group (Linux)
sudo usermod -aG docker $USER
newgrp docker
```

---

## Best Practices

1. **Use version control** for configuration files
2. **Test with `--dry-run`** before applying changes
3. **Use `plan` commands** to preview changes
4. **Keep credentials secure** - use environment variables or secrets manager
5. **Back up volumes** before using `--force-delete-volumes`
6. **Monitor with `infra status`** in production
7. **Use DOMjudge web UI** for contest management after initial setup
