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
git clone <repository-url>
cd football
2. Run Build
./docker-universal-build.sh
That's it! Everything else happens inside Docker.
What This Does
The docker-universal-build.sh script:
- Builds Docker image with all required tools
- Generates WireGuard keys (inside Docker)
- Bootstraps Debian (inside Docker)
- Applies configurations (inside Docker)
- Runs hardening (inside Docker)
- Creates disk images (inside Docker)
- Tests in VM (inside Docker)
- Verifies compliance (inside Docker)
- Creates build report (on host)
Build Timeline
| Phase | Time | What Happens |
|---|---|---|
| Docker image build | 3-5 min | Downloads and installs tools |
| WireGuard key gen | 10 sec | Generates keys |
| Debian bootstrap | 10-15 min | Downloads and installs Debian 13 |
| Configuration | 2 min | Applies overlay files |
| Hardening | 2 min | Runs security scripts |
| Disk image creation | 5-8 min | Creates .img and .qcow2 files |
| VM boot test | 1-2 min | Boots and checks system |
| Compliance tests | 2-3 min | Validates all security controls |
| TOTAL | ~30-40 min | Complete end-to-end build |

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

Troubleshooting
Build Fails
Problem: Docker build fails
Solution:
# 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:
# 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:
# 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:
# 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
