# Football Secure Access System - Universal Docker Build

## 🎯 Works on ANY System with Docker!

**Requirements**: ONLY Docker and a shell
**Platform Support**:
- ✅ Linux (any distro)
- ✅ macOS (with Docker Desktop)
- ✅ Windows (with Docker Desktop or WSL2)
- ✅ No root/sudo required on host
- ✅ No host tools needed (debootstrap, qemu, etc.)
- ✅ Entire build process runs inside Docker

---

## Quick Start

### 1. Clone Repository

```bash
git clone <repository-url>
cd football
```

### 2. Run Build

```bash
./docker-universal-build.sh
```

That's it! Everything else happens inside Docker.

---

## What This Does

The `docker-universal-build.sh` script:

1. **Builds Docker image** with all required tools
2. **Generates WireGuard keys** (inside Docker)
3. **Bootstraps Debian** (inside Docker)
4. **Applies configurations** (inside Docker)
5. **Runs hardening** (inside Docker)
6. **Creates disk images** (inside Docker)
7. **Tests in VM** (inside Docker)
8. **Verifies compliance** (inside Docker)
9. **Creates build report** (on host)

## Architecture

### Host System Requirements

**ONLY**:
- Docker installed and running
- A shell (bash, zsh, etc.)
- Git (optional, for cloning repo)

**NOT REQUIRED**:
- ❌ debootstrap
- ❌ qemu-img
- ❌ qemu-system
- ❌ kpartx
- ❌ WireGuard tools
- ❌ sudo/root access
- ❌ Linux-specific tools

### Docker Container

**Everything happens here**:
- ✅ debootstrap (for Debian bootstrap)
- ✅ qemu-img (for disk images)
- ✅ qemu-system (for VM testing)
- ✅ kpartx (for partitioning)
- ✅ WireGuard (for key generation)
- ✅ grub2 (for UEFI boot)
- ✅ All build tools
- ✅ All system operations

### Volume Mounts

```
Host                          Container (Docker)
-----------------              ----------------
./football                  →    /build
./football/output          →    /build/output
./football/config          →    /build/config
./football/chroot-overlay   →    /build/chroot-overlay
```

---

## Build Process Detail

### Phase 1: Build Environment (3-5 min)

```dockerfile
FROM debian:trixie
RUN apt-get install -y \
    debootstrap \
    qemu-utils \
    qemu-system-x86 \
    kpartx \
    grub2-common \
    wireguard-tools \
    ...
```

**What happens**:
- Downloads Debian base image
- Installs ALL build tools
- Creates reproducible build environment

---

### Phase 2: WireGuard Keys (10 sec)

```bash
wg genkey > private.key
wg pubkey < private.key > public.key
```

**What happens**:
- Generates WireGuard key pair
- Stores securely (chmod 600 private.key)
- Keys used in WireGuard configuration

---

### Phase 3: Debian Bootstrap (10-15 min)

```bash
debootstrap --arch=amd64 --variant=minbase trixie /build/chroot
```

**What happens**:
- Downloads minimal Debian 13 (trixie)
- Installs base system (~200MB)
- Creates functional chroot environment
- ~150-200 packages installed

---

### Phase 4: Configuration (2 min)

```bash
cp -r chroot-overlay/* chroot/
```

**What happens**:
- Applies all configuration files
- Sets up kernel parameters (sysctl)
- Configures password policy (pwquality)
- Sets up audit rules (auditd)
- Configures logging (rsyslog)
- Sets up systemd services
- Configures WireGuard

---

### Phase 5: Hardening (2 min)

```bash
# In chroot
systemctl mask ssh sshd telnet
systemctl enable block-remote-access
```

**What happens**:
- Disables remote access services
- Enables security services
- Applies firewall rules
- Initializes AIDE database
- Sets up auditd
- Configures AppArmor

---

### Phase 6: Disk Images (5-8 min)

```bash
# Create 8GB raw image
qemu-img create -f raw football-physical.img 8G

# Partition with GPT
sfdisk football-physical.img << EOF
label: gpt
size=512MiB,type=C12A7328-F81F-11D2-BA4B-00A0C93EC93B
type=0FC63DAF-8483-4772-8E79-3D69D8477DE4
EOF

# Setup loop device
losetup -f --show -P football-physical.img

# Create filesystems
mkfs.vfat -F32 ${LOOP_DEV}p1  # EFI System Partition
mkfs.ext4 ${LOOP_DEV}p2        # Root partition

# Copy chroot
cp -a chroot/. ${LOOP_DEV}p2

# Install GRUB (UEFI)
chroot ${LOOP_DEV}p2 grub-install --target=x86_64-efi

# Convert to QCOW2
qemu-img convert -f raw -O qcow2 football-physical.img football-vm.qcow2
```

**What happens**:
- Creates 8GB raw disk image
- Partitions with GPT (ESP + root)
- Formats filesystems (FAT32, ext4)
- Copies Debian system to image
- Installs GRUB for UEFI boot
- Converts to QCOW2 format for VMs

---

### Phase 7: VM Boot Test (1-2 min)

```bash
qemu-system-x86_64 \
    -m 2048 \
    -drive file=football-vm.qcow2,format=qcow2 \
    -nographic \
    -serial file:console.log \
    -daemonize
```

**What happens**:
- Boots system in QEMU
- Monitors console output
- Checks for login prompt
- Verifies system boots successfully

---

### Phase 8: Compliance Tests (2-3 min)

```bash
# Test kernel parameters
grep -q "net.ipv4.ip_forward = 0" sysctl.conf

# Test password policy
grep -q "minlen = 14" pwquality.conf

# Test audit rules
wc -l audit/rules.d/cis-audit.rules

# Test WireGuard
grep -q "PrivateKey" wireguard/wg0.conf

# ... (10+ more tests)
```

**What happens**:
- Validates all configuration files
- Checks security controls
- Verifies compliance requirements
- Tests system readiness

---

## Deployment

### Physical Hardware

```bash
# 1. Copy image to USB
sudo dd if=output/football-physical.img of=/dev/sdX bs=4M status=progress

# 2. Boot from USB
# 3. Configure WireGuard endpoint
# 4. Change default password
```

### Virtual Machine

```bash
# 1. Boot with QEMU
qemu-system-x86_64 \
    -m 2048 \
    -drive file=output/football-vm.qcow2,format=qcow2

# 2. Login: user / changeme
# 3. Configure WireGuard endpoint
# 4. Change password
```

### Docker (Container Deployment)

```bash
# 1. Import root filesystem
docker import football-physical.img football:trixie

# 2. Run container
docker run --privileged football:trixie
```

---

## Configuration

### Before Building

Update `docker-universal-build.sh`:

```bash
# WireGuard endpoint (replace with your VPN server)
WG_ENDPOINT_IP="10.100.0.1"
WG_ENDPOINT_PORT="51820"
```

### After Building (First Boot)

```bash
# 1. Login to system
user
changeme

# 2. Change password
passwd

# 3. Configure WireGuard (if needed)
sudo nano /etc/wireguard/wg0.conf
sudo systemctl restart wg-quick@wg0

# 4. Run compliance tests
sudo ./tests/verify-compliance.sh
```

## Troubleshooting

### Build Fails

**Problem**: Docker build fails

**Solution**:
```bash
# Check Docker is running
docker ps

# Check Docker version
docker --version

# Clean and retry
docker system prune -a
./docker-universal-build.sh
```

---

### No Images Created

**Problem**: Build completes but no images in output/

**Solution**:
```bash
# Check disk space
df -h

# Check output directory
ls -la output/

# Check build logs
cat BUILD-REPORT.txt
```

---

### VM Won't Boot

**Problem**: VM starts but doesn't boot

**Solution**:
```bash
# Check console logs
cat output/console.log

# Try with more memory
qemu-system-x86_64 -m 4096 -drive file=output/football-vm.qcow2

# Check image
qemu-img info output/football-vm.qcow2
```

---

### WireGuard Not Connecting

**Problem**: WireGuard shows "Handshake did not complete"

**Solution**:
```bash
# 1. Check endpoint is correct
sudo cat /etc/wireguard/wg0.conf

# 2. Check endpoint is reachable
ping <WG_ENDPOINT_IP>
telnet <WG_ENDPOINT_IP> <WG_ENDPOINT_PORT>

# 3. Check firewall on endpoint
# Make sure UDP port 51820 is allowed

# 4. Check keys match
# Private key on client must match public key on server
```
