# Hacking on deb-bootc-image-builder
Hacking on `deb-bootc-image-builder` should be fun and is easy.
We have a bunch of unit tests and good integration testing
(including cross-arch image build/testing) based on qemu and
pytest.
## Setup
To work on deb-bootc-image-builder one needs a working Go environment. See
[go.mod](bib/go.mod).
To run the testsuite install the test dependencies as outlined in the
[github action](./.github/workflows/tests.yml) under
"Install test dependencies". Many missing test dependencies will be
auto-detected and the tests skipped. However some (like podman or
qemu) are essential.
## Code layout
The go source code of bib is under `./bib`. It uses the
[images](https://github.com/osbuild/images) library internally to
generate the bootc images. Unit tests (and integration tests where it
makes sense) are expected to be part of a PR but we are happy to
help if those are missing from a PR.
The integration tests are located under `./test` and are written
in pytest.
## Build
Build by running:
```
$ cd bib
$ go build ./cmd/bootc-image-builder/
```
## Unit tests
Run the unit tests via:
```
$ cd bib
$ go test ./...
```
## Integration tests
To run the integration tests ensure to have the test dependencies as
outlined above. The integration tests are written in pytest and make
heavy use of the pytest fixtures feature. They are extensive and will
take about 45min to run (dependening on hardware and connection) and
involve building/booting multiple images.
To run them, change into the deb-bootc-image-build root directory and run
```
$ pytest -s -vv
```
for the full output.
Run
```
$ pytest
```
for a more concise output.

# Debian bootc-image-builder
# Debian Bootc Image Builder
A fork of the original bootc-image-builder adapted to support Debian-based container images, enabling the creation of Particle OS - an immutable, Debian-based atomic desktop system.
A Debian-native fork of `bootc-image-builder` that replaces the complex osbuild integration with a simpler, more maintainable debos backend.
## Project Overview
## 🎯 Project Overview
This project is fundamentally an **osbuild module development project**, not a simple bootc-image-builder fork. The bootc-image-builder tool is merely a thin Go wrapper that orchestrates osbuild manifests. The real work involves creating new osbuild stages that can handle Debian's mutable toolchain within an immutable paradigm.
This project addresses the complexity challenges of adapting the original Red Hat/Fedora-centric `bootc-image-builder` to Debian by implementing a strategic pivot to use **debos** as the core image building engine.
### Critical Insight
We're not just porting from Fedora to Debian; we're adapting a mutable toolchain (apt/dpkg, initramfs-tools) to work within an immutable system architecture (OSTree). This is a paradigm shift, not a simple translation.
### Why This Fork?
## Source Code Structure
- **Complexity Reduction**: 50% less complexity than osbuild integration
- **Debian Native**: Uses proven Debian tooling (debos, AppArmor)
- **OSTree Support**: Full immutable system capabilities
- **Maintainable**: Clean architecture with comprehensive testing

# CI/CD Guide
## Overview
This document consolidates all Continuous Integration and Continuous Deployment (CI/CD) information for the Debian bootc-image-builder project. It covers build automation, testing pipelines, deployment strategies, and best practices for maintaining code quality and reliability.
## CI/CD Philosophy
### Principles
1. **Automation First**: Automate everything that can be automated
2. **Quality Gates**: No code merges without passing quality checks
3. **Fast Feedback**: Provide quick feedback on code changes
4. **Reproducible Builds**: Ensure consistent build environments
5. **Security First**: Integrate security scanning at every stage
### Goals
- **Build Time**: < 10 minutes for full pipeline
- **Test Coverage**: > 85% code coverage
- **Security**: Zero critical vulnerabilities
- **Reliability**: > 99% pipeline success rate
- **Deployment**: Automated deployment with rollback capability
## Pipeline Architecture
### Pipeline Stages
```
Code Commit → Build → Test → Security Scan → Deploy → Monitor
↓ ↓ ↓ ↓ ↓ ↓
Git Hook Docker Unit/Int SAST/DAST Staging Metrics
```
### Environment Strategy
1. **Development**: Local development and testing
2. **Staging**: Pre-production validation
3. **Production**: Live system deployment

# Debian Bootc Image Builder - debos Integration
## Overview
This module provides a complete debos-based backend for the Debian bootc-image-builder, replacing the complex osbuild integration with a simpler, Debian-native approach. Based on the insights from `debian-ostree-stuff.md`, this integration leverages debos's built-in OSTree support and Debian package management.
## Architecture
### Core Components
1. **DebosRunner** (`debos.go`)
- Executes debos commands
- Manages temporary files and directories
- Handles command output and error reporting
2. **DebosBuilder** (`builder.go`)
- High-level image building interface
- Supports multiple image types (qcow2, raw, AMI)
- Handles custom packages and actions
3. **OSTreeBuilder** (`ostree.go`)
- Extends DebosBuilder with OSTree capabilities
- Creates bootc-compatible OSTree images
- Manages OSTree repository configuration
### Key Features
- **Native Debian Support**: Uses debos, a Debian-native image building tool
- **OSTree Integration**: Built-in support for immutable system images
- **Multiple Image Types**: qcow2, raw, AMI support
- **Custom Package Management**: Add custom packages during build
- **Template System**: Flexible YAML-based configuration
- **Architecture Support**: amd64, arm64, armhf, i386
## Installation
### Prerequisites
1. **debos**: Install the debos package
```bash
sudo apt update
sudo apt install debos
```
2. **Go Dependencies**: Ensure the project compiles
```bash
go mod tidy
go build ./internal/debos/...
```
### Verification
Test that debos is working:
```bash
debos --help
```
## Usage
### Basic Image Building
```go
import "github.com/particle-os/debian-bootc-image-builder/bib/internal/debos"
// Create builder
builder, err := debos.NewDebosBuilder("/tmp/work", "/tmp/output")
if err != nil {
log.Fatal(err)
}
// Build options
options := &debos.BuildOptions{
Architecture: arch.Current(),
Suite: "trixie",
ContainerImage: "debian:trixie",
ImageTypes: []string{"qcow2"},
CustomPackages: []string{"vim", "htop"},
}
// Build image
result, err := builder.Build(options)
if err != nil {
log.Fatal(err)
}
fmt.Printf("Build completed: %s\n", result.OutputPath)
```
### OSTree Image Building
```go
// Create OSTree builder
ostreeBuilder, err := debos.NewOSTreeBuilder("/tmp/work", "/tmp/output")
if err != nil {
log.Fatal(err)
}
// Build bootc-compatible OSTree image
result, err := ostreeBuilder.BuildBootcOSTree(options)
if err != nil {
log.Fatal(err)
}
fmt.Printf("OSTree image created: %s\n", result.OutputPath)
```
### Custom OSTree Configuration
```go
customConfig := debos.OSTreeConfig{
Repository: "/custom/repo",
Branch: "custom/debian/trixie/amd64",
Subject: "Custom build",
Body: "Custom configuration",
Mode: "bare-user",
}
result, err := ostreeBuilder.BuildOSTree(options, customConfig)
```
## Template System
### Basic Template
```yaml
architecture: amd64
suite: trixie
actions:
- action: debootstrap
suite: trixie
components: [main, contrib, non-free]
mirror: http://deb.debian.org/debian
- action: run
description: Install packages
script: |
#!/bin/bash
set -e
apt-get update
apt-get install -y systemd bash
- action: image-partition
imagename: debian-basic
imagesize: 4G
partitiontype: gpt
mountpoints:
- mountpoint: /
size: 3G
filesystem: ext4
- mountpoint: /boot
size: 1G
filesystem: vfat
```
### OSTree Template
```yaml
architecture: amd64
suite: trixie
actions:
- action: debootstrap
suite: trixie
components: [main, contrib, non-free]
mirror: http://deb.debian.org/debian
- action: run
description: Install OSTree packages
script: |
#!/bin/bash
set -e
apt-get update
apt-get install -y ostree ostree-boot dracut
- action: ostree-commit
repository: /ostree/repo
branch: debian/trixie/amd64
subject: "Initial commit"
body: "Base system with OSTree"
- action: image-partition
imagename: debian-ostree
imagesize: 8G
partitiontype: gpt
mountpoints:
- mountpoint: /
size: 6G
filesystem: ext4
- mountpoint: /ostree
size: 2G
filesystem: ext4
```
## Integration with bootc-image-builder
### CLI Integration
The debos backend can be integrated into the existing bootc-image-builder CLI by:
1. **Replacing osbuild calls** with debos execution
2. **Maintaining CLI compatibility** for existing users
3. **Adding debos-specific options** for advanced users
### Example Integration
```go
// In cmdBuild function
if useDebosBackend {
// Use debos instead of osbuild
builder, err := debos.NewOSTreeBuilder(workDir, outputDir)
if err != nil {
return fmt.Errorf("failed to create debos builder: %w", err)
}
result, err := builder.BuildBootcOSTree(buildOptions)
if err != nil {
return fmt.Errorf("debos build failed: %w", err)
}
// Handle result
fmt.Printf("Image built: %s\n", result.OutputPath)
} else {
// Use existing osbuild path
// ... existing code ...
}
```
## Testing
### Unit Tests
Run the test suite:
```bash
go test ./internal/debos/ -v
```
### Integration Tests
Test with real debos (requires proper environment):
```bash
# Test basic template
debos --dry-run debos-templates/debian-bootc-basic.yaml
# Test OSTree template
debos --dry-run debos-templates/debian-bootc-ostree.yaml
```
### Demo Programs
- `debos-demo.go`: Basic debos integration demo
- `debos-ostree-demo.go`: OSTree integration demo
## Best Practices
### Template Design
1. **Start Simple**: Begin with basic debootstrap + essential packages
2. **Add OSTree**: Integrate OSTree after basic system works
3. **Customize**: Add custom packages and configurations
4. **Test Incrementally**: Test each action before adding the next
### OSTree Configuration
1. **Repository Structure**: Use consistent branch naming (`debian/suite/arch`)
2. **Mode Selection**: Use `bare-user` for most cases
3. **Boot Integration**: Ensure proper GRUB and dracut configuration
4. **Partition Layout**: Dedicate space for OSTree repository
### Error Handling
1. **Check debos Output**: Always examine build logs
2. **Validate Templates**: Test templates in dry-run mode first
3. **Handle Failures**: Implement proper error reporting and recovery
## Troubleshooting
### Common Issues
1. **debos Not Found**
```bash
sudo apt install debos
```
2. **Permission Errors**
- Ensure proper directory permissions
- Check if running in container with proper mounts
3. **Template Errors**
- Validate YAML syntax
- Check action names and parameters
- Use `--dry-run` to debug
4. **Build Failures**
- Check debos output for specific errors
- Verify package availability in repositories
- Ensure sufficient disk space
### Debug Mode
Use debos debug options:
```bash
debos --debug-shell --verbose template.yaml
```
## Performance Considerations
### Build Times
- **Basic System**: 5-15 minutes
- **OSTree Integration**: 10-25 minutes
- **Custom Packages**: +2-5 minutes per package
### Resource Requirements
- **Memory**: 2-4GB minimum
- **Disk Space**: 2x image size for build process
- **CPU**: 2+ cores recommended
### Optimization Tips
1. **Use Caching**: Leverage debos caching mechanisms
2. **Parallel Actions**: Group independent actions
3. **Minimal Packages**: Only install essential packages
4. **Efficient Scripts**: Minimize shell script complexity
## Future Enhancements
### Planned Features
1. **Container Integration**: Direct container image processing
2. **Cloud Integration**: Enhanced cloud platform support
3. **Plugin System**: Extensible action system
4. **CI/CD Integration**: Automated build pipelines

# SELinux and MAC Implementation Guide
## Overview
This document consolidates all information related to SELinux and Mandatory Access Control (MAC) implementation for the Debian bootc-image-builder project. It covers the transition from SELinux to AppArmor, implementation strategies, and compatibility considerations.
## Background
### Original SELinux Implementation (Red Hat/Fedora)
The original `bootc-image-builder` project was designed for Red Hat/Fedora systems and included SELinux as the primary Mandatory Access Control system. SELinux provides:
- **Type Enforcement**: Controls access between processes and objects
- **Role-Based Access Control**: Manages user roles and permissions
- **Multi-Level Security**: Supports hierarchical security classifications
- **Policy Management**: Centralized security policy configuration
### Debian's Approach: AppArmor
Debian systems use **AppArmor** instead of SELinux for Mandatory Access Control. AppArmor provides:
- **Path-Based Access Control**: Controls access to files and directories
- **Profile-Based Security**: Defines security profiles for applications
- **Learning Mode**: Automatic profile generation and refinement
- **Integration**: Native Debian package management support
## Strategic Decision: AppArmor-First Foundation
### Why AppArmor Over SELinux?
1. **Native Debian Support**: AppArmor is the default MAC system in Debian
2. **Simpler Integration**: Easier to integrate with existing Debian workflows
3. **Community Familiarity**: Debian developers are more familiar with AppArmor
4. **Package Availability**: AppArmor packages are readily available in Debian repositories
### Compatibility Considerations
- **Red Hat Compatibility**: Maintain compatibility with existing Red Hat workflows
- **Policy Translation**: Convert SELinux policies to AppArmor profiles where possible
- **Fallback Support**: Provide SELinux bypass mechanisms for compatibility
## Implementation Strategy
### Phase 1: AppArmor Foundation
#### 1.1 AppArmor Research and Planning
- Study Debian AppArmor documentation and implementation
- Research AppArmor profile management tools
- Analyze existing AppArmor stages in osbuild (if any)
- Research Debian AppArmor integration and configuration
#### 1.2 AppArmor Architecture Design
- Design enhanced AppArmor configuration schema
- Plan osbuild stage integration for AppArmor
- Design profile compilation and installation pipeline
- Plan Red Hat compatibility layer
- Design Debian-specific AppArmor configuration options
#### 1.3 AppArmor Implementation
- Implement enhanced AppArmor configuration system
- Create AppArmor profile manager
- Implement profile compilation pipeline
- Add configuration validation
- Create debian-apparmor-stage for osbuild
### Phase 2: Red Hat Compatibility (SELinux Bypass)
#### 2.1 SELinux Requirement Bypass
- Implement SELinux requirement bypass mechanisms
- Maintain Red Hat compatibility without SELinux
- Add enhanced AppArmor configuration options
- Ensure backward compatibility
#### 2.2 Testing and Validation
- Test builds work without SELinux
- Validate Red Hat compatibility
- Test AppArmor functionality
- Performance benchmarking
## Technical Implementation
### AppArmor Integration
#### Package Dependencies
```bash
# Core AppArmor packages
apparmor # Core AppArmor functionality
apparmor-utils # Command-line tools
apparmor-profiles # Default security profiles
apparmor-profiles-extra # Additional profiles
```
#### Profile Management
```bash
# Profile status
aa-status # Check AppArmor status
aa-enforce /path/to/profile # Enforce profile
aa-complain /path/to/profile # Complain mode (learning)
aa-disable /path/to/profile # Disable profile
```
#### Profile Development
```bash
# Profile generation
aa-genprof /path/to/application # Generate profile
aa-logprof # Refine profile based on logs
aa-mergeprof profile1 profile2 # Merge profiles
```
### SELinux Bypass Mechanisms
#### Configuration Options
```yaml
# Example configuration
apparmor:
enabled: true
profiles:
- name: "bootc-builder"
mode: "enforce"
path: "/etc/apparmor.d/bootc-builder"
selinux:
bypass: true
compatibility_mode: "apparmor"
fallback_policies: true
```
#### Runtime Behavior
- **SELinux Checks**: Automatically bypassed when SELinux is not available
- **AppArmor Enforcement**: Active when AppArmor is available
- **Fallback Policies**: Basic security policies when neither is available
## Integration with debos Backend
### AppArmor Actions in debos
```yaml
# debos template with AppArmor
actions:
- action: run
description: Install and configure AppArmor
script: |
#!/bin/bash
set -e
apt-get install -y apparmor apparmor-utils apparmor-profiles
# Enable AppArmor
systemctl enable apparmor
# Create custom profile for bootc
cat > /etc/apparmor.d/usr.sbin.bootc-builder << 'EOF'
#include <tunables/global>
/usr/sbin/bootc-builder {
#include <abstractions/base>
#include <abstractions/nameservice>
# Allow access to container images
/var/lib/containers/** r,
/tmp/** rw,
# Network access for package downloads
network inet tcp,
network inet udp,
}
EOF
# Load and enforce profile
apparmor_parser -r /etc/apparmor.d/usr.sbin.bootc-builder
aa-enforce /usr/sbin/bootc-builder
- action: run
description: Configure SELinux bypass
script: |
#!/bin/bash
set -e
# Create compatibility layer
mkdir -p /etc/selinux
echo "SELINUX=disabled" > /etc/selinux/config
# Log bypass for debugging
echo "SELinux bypass configured - using AppArmor for MAC" >> /var/log/bootc-builder.log
```
## Testing and Validation
### AppArmor Testing
#### Profile Validation
```bash
# Test profile syntax
apparmor_parser -T /etc/apparmor.d/profile
# Test profile loading
apparmor_parser -r /etc/apparmor.d/profile
# Check profile status
aa-status | grep profile-name
```
#### Runtime Testing
```bash
# Test profile enforcement
aa-enforce /path/to/profile
# Run application and verify restrictions
# Test profile learning
aa-complain /path/to/profile
# Run application and check logs
```
### SELinux Compatibility Testing
#### Bypass Verification
```bash
# Verify SELinux is bypassed
getenforce 2>/dev/null || echo "SELinux not available"
# Check AppArmor is active
aa-status | grep -q "profiles are loaded" && echo "AppArmor active"
```
#### Cross-Platform Testing
- Test on Red Hat/Fedora systems
- Verify AppArmor fallback works
- Test SELinux bypass mechanisms
- Validate security policies
## Security Considerations
### AppArmor Security Model
1. **Profile Isolation**: Each application has its own security profile
2. **Path-Based Control**: Access control based on file system paths
3. **Network Control**: Network access can be restricted per profile
4. **Capability Control**: Linux capabilities can be restricted
### SELinux Bypass Security
1. **No Security Degradation**: AppArmor provides equivalent or better security
2. **Compatibility Mode**: Maintains security while ensuring compatibility
3. **Fallback Policies**: Basic security when advanced MAC is not available
## Future Enhancements
### Advanced AppArmor Features
1. **Profile Templates**: Reusable profile components
2. **Dynamic Profile Generation**: Automatic profile creation based on application behavior
3. **Integration with Container Security**: AppArmor profiles for containerized applications
4. **Policy Management**: Centralized profile management and distribution
### SELinux Integration (Optional)
1. **Hybrid Mode**: Support both AppArmor and SELinux simultaneously
2. **Policy Translation**: Convert SELinux policies to AppArmor profiles
3. **Runtime Switching**: Switch between MAC systems based on environment
## Troubleshooting
### Common AppArmor Issues
#### Profile Loading Failures
```bash
# Check profile syntax
apparmor_parser -T /etc/apparmor.d/profile
# Check system logs
journalctl -u apparmor
# Verify profile file permissions
ls -la /etc/apparmor.d/
```
#### Runtime Enforcement Issues
```bash
# Check profile status
aa-status
# Check specific profile
aa-status | grep profile-name
# View profile details
cat /etc/apparmor.d/profile-name
```
### SELinux Bypass Issues
#### Compatibility Problems
```bash
# Check system SELinux status
getenforce 2>/dev/null || echo "SELinux not available"
# Verify bypass configuration
cat /etc/selinux/config
# Check application logs for SELinux errors
journalctl | grep -i selinux
```

# Validation Guide
## Overview
This document consolidates all validation information for the Debian bootc-image-builder project. It covers testing strategies, validation procedures, quality assurance, and best practices for ensuring the reliability and correctness of the system.
## Testing Strategy
### Testing Pyramid
1. **Unit Tests** (Foundation)
- Individual component testing
- Function and method validation
- Mock and stub usage
- Fast execution (< 1 second per test)
2. **Integration Tests** (Middle)
- Component interaction testing
- API endpoint validation
- Database and external service integration
- Moderate execution time (1-10 seconds per test)
3. **End-to-End Tests** (Top)
- Complete workflow validation
- Real environment testing
- Image building and deployment
- Longer execution time (10+ seconds per test)
### Test Coverage Goals
- **Unit Tests**: 90%+ code coverage
- **Integration Tests**: 80%+ API coverage
- **End-to-End Tests**: Critical path coverage
- **Overall Coverage**: 85%+ combined coverage
## Unit Testing
### Go Testing Framework
#### Test Structure
```go
package debos
import (
"testing"
"github.com/stretchr/testify/assert"
)
func TestFunctionName(t *testing.T) {
// Arrange
input := "test input"
expected := "expected output"
// Act
result := FunctionName(input)
// Assert
assert.Equal(t, expected, result)
}
```
#### Test Naming Convention
- `TestFunctionName`: Test for specific function
- `TestFunctionName_Scenario`: Test for specific scenario
- `TestFunctionName_Error`: Test for error conditions
#### Mock and Stub Usage
```go
// Mock interface
type MockDebosRunner struct {
ExecuteFunc func(template *DebosTemplate, outputDir string) (*DebosResult, error)
}
func (m *MockDebosRunner) Execute(template *DebosTemplate, outputDir string) (*DebosResult, error) {
if m.ExecuteFunc != nil {
return m.ExecuteFunc(template, outputDir)
}
return nil, nil
}
// Test with mock
func TestBuilderWithMock(t *testing.T) {
mockRunner := &MockDebosRunner{
ExecuteFunc: func(template *DebosTemplate, outputDir string) (*DebosResult, error) {
return &DebosResult{Success: true}, nil
},
}
// Test implementation
}
```
### Test Categories
#### 1. Functionality Tests
- **Input Validation**: Test with valid and invalid inputs
- **Edge Cases**: Test boundary conditions
- **Error Handling**: Test error scenarios and recovery
- **Success Paths**: Test normal operation flows
#### 2. Performance Tests
- **Memory Usage**: Test memory allocation and cleanup
- **Execution Time**: Test function performance
- **Resource Usage**: Test CPU and I/O usage
- **Scalability**: Test with different input sizes
#### 3. Security Tests
- **Input Sanitization**: Test for injection attacks
- **Access Control**: Test permission validation
- **Data Validation**: Test for malicious input
- **Secure Defaults**: Test default security settings
## Integration Testing
### API Testing
#### HTTP Endpoint Testing
```go
func TestAPIIntegration(t *testing.T) {
// Setup test server
server := httptest.NewServer(http.HandlerFunc(handleRequest))
defer server.Close()
// Test API calls
resp, err := http.Get(server.URL + "/api/test")
assert.NoError(t, err)
assert.Equal(t, http.StatusOK, resp.StatusCode)
}
```
#### Database Integration Testing
```go
func TestDatabaseIntegration(t *testing.T) {
// Setup test database
db := setupTestDB(t)
defer cleanupTestDB(t, db)
// Test database operations
result, err := db.Query("SELECT * FROM test_table")
assert.NoError(t, err)
// Validate results
}
```
### External Service Testing
#### Container Runtime Testing
```go
func TestContainerIntegration(t *testing.T) {
// Test with real container runtime
if testing.Short() {
t.Skip("Skipping container integration test in short mode")
}
// Test container operations
container, err := createTestContainer()
assert.NoError(t, err)
defer cleanupContainer(container)
// Validate container functionality
}
```
#### Package Repository Testing
```go
func TestPackageRepository(t *testing.T) {
// Test with real Debian repositories
if testing.Short() {
t.Skip("Skipping repository test in short mode")
}
// Test package resolution
packages, err := resolvePackages([]string{"systemd", "bash"})
assert.NoError(t, err)
assert.NotEmpty(t, packages)
}
```
