# 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
### Community Contributions
1. **Template Library**: Share and reuse templates
2. **Action Development**: Create custom debos actions
3. **Documentation**: Improve guides and examples
4. **Testing**: Expand test coverage and scenarios

# 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)
}
```
