🚀 1. osbuild (Core Engine)
Repository: osbuild/osbuild
Role: Core pipeline execution engine
Language: Python
Status: Foundation component
What It Is
The core OSBuild engine that executes declarative pipelines to build operating system artifacts. It's the foundation upon which all other components are built.
Key Features
- Pipeline-based architecture - Declarative JSON manifests define build processes
- Stage system - Composable building blocks for OS construction
- Assembler system - Multiple output formats (QEMU, OSTree, tar, etc.)
- Runner support - Linux, QEMU, and other execution environments
- Extensible - Custom stages and assemblers can be added
How It Works
- Parse manifest - JSON configuration defines the build pipeline
- Execute stages - Each stage modifies the filesystem tree
- Run assembler - Final stage creates the desired output format
- Output artifact - QEMU image, OSTree commit, tar archive, etc.
Example Usage
# Build from manifest
osbuild --json manifest.json
# List available stages
osbuild --list-stages
# Validate manifest
osbuild --check manifest.json
🎼 2. osbuild-composer
Repository: osbuild/osbuild-composer
Role: HTTP service for image composition
Language: Go
Status: Production-ready service layer
What It Is
A high-level HTTP service that sits above the core osbuild engine, providing standardized image types and APIs for building operating system images. It's the "orchestrator" that translates user requests into osbuild pipelines.
Key Features
- HTTP API service - RESTful interface for image building
- Predefined image types - Standardized OS compositions
- Multiple APIs - lorax-composer compatibility, cloud APIs
- Blueprint system - Policy layer for user configuration
- Distribution support - RHEL, Fedora, CentOS, and others
- Target uploads - AWS, Azure, GCP, local storage
