# 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)
|
||||
|
||||

|
||||
## Output Files
|
||||
|
||||
After successful build:
|
||||
|
||||
```
|
||||
football/
|
||||
├── output/
|
||||
│ ├── football-physical.img # 8GB raw image for physical hardware
|
||||
│ ├── football-vm.qcow2 # QCOW2 image for QEMU
|
||||

|
||||
├── private.key # WireGuard private key
|
||||
├── public.key # WireGuard public key
|
||||
└── BUILD-REPORT.txt # Detailed build report
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 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

|
||||
|
||||
**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
|
||||
```
