# apt-ostree
|
|
|
|
**apt-ostree** is a Debian/Ubuntu equivalent of rpm-ostree, providing atomic system updates, package management, and container image generation for Debian-based systems.
|
|
|
|
## 🎉 **Major Milestone Achieved: Bootc Image Generation 100% Working!**
|
|
|
|
The project has successfully implemented a complete bootc image generation system that creates OCI-compatible container images from OSTree trees. This feature enables users to generate container images that can be used with bootc and other container orchestration systems.
|
|
|
|
### ✅ **What's Working Now**
|
|
- **Complete bootc image generation** with OCI/Docker export
|
|
- **Full OSTree integration** for atomic deployments
|
|
- **Real APT package management** with dependency resolution
|
|
- **System management commands** (status, upgrade, rollback)
|
|
- **Tree composition** from YAML treefiles
|
|
- **Multi-format container export** (Docker archive, OCI)
|
|
|
|
### 🔄 **In Progress**
|
|
- **D-Bus infrastructure** for client-daemon communication
|
|
- **Real-time transaction management**
|
|
- **Enhanced system monitoring**
|
|
|
|
## Features
|
|
|
|
### 🐳 **Container Image Generation**
|
|
```bash
|
|
# Generate a bootc-compatible container image
|
|
apt-ostree compose tree treefile.yaml --container --verbose
|
|
|
|
# The generated image includes:
|
|
# - Complete Debian system with APT tools
|
|
# - Bash shell and core utilities
|
|
# - Systemd init system
|
|
# - All requested packages and dependencies
|
|
# - OCI-compatible metadata
|
|
```
|
|
|
|
### 📦 **Package Management**
|
|
```bash
|
|
# Install packages
|
|
apt-ostree install firefox-esr
|
|
|
|
# Search for packages
|
|
apt-ostree search "web browser"
|
|
|
|
# Uninstall packages
|
|
apt-ostree uninstall firefox-esr
|
|
```
|
|
|
|
### 🖥️ **System Management**
|
|
```bash
|
|
# Check system status
|
|
apt-ostree status
|
|
|
|
# Perform system upgrade
|
|
apt-ostree upgrade
|
|
|
|
# Rollback to previous deployment
|
|
apt-ostree rollback
|
|
```
|
|
|
|
### 🌳 **Tree Composition**
|
|
```yaml
|
|
# Example treefile.yaml
|
|
ref: debian/13/x86_64
|
|
repos:
|
|
- name: debian
|
|
url: http://deb.debian.org/debian
|
|
packages:
|
|
include:
|
|
- bash
|
|
- systemd
|
|
- firefox-esr
|
|
```
|
|
|
|
## Quick Start
|
|
|
|
### Prerequisites
|
|
- Debian 13+ or Ubuntu 24.04+
|
|
- OSTree installed and configured
|
|
- Podman or Docker for container operations
|
|
|
|
### Installation
|
|
```bash
|
|
# Clone the repository
|
|
git clone https://github.com/your-org/apt-ostree.git
|
|
cd apt-ostree
|
|
|
|
# Build the project
|
|
cargo build --release
|
|
|
|
# Test bootc image generation
|
|
./test-compose-container.sh
|
|
```
|
|
|
|
### Generate Your First Image
|
|
```bash
|
|
# Create a minimal system
|
|
apt-ostree compose tree minimal-treefile.yaml --container --verbose
|
|
|
|
# Load and test the image
|
|
podman load -i output/test_minimal.tar
|
|
podman run --rm localhost/test/minimal:latest echo "Hello from bootc!"
|
|
```
|
|
|
