# bootc-image-builder
A tool to convert bootc container images to bootable disk images. This tool creates bootable VM images from bootc-compatible container images, handling the complete bootc workflow including OSTree integration, composefs setup, initramfs creation, and bootloader installation.
## Features
- ✅ **Multi-format Support**: QCOW2, Raw, VMDK, ISO, AMI
- ✅ **Bootc Integration**: Full bootc container image support
- ✅ **OSTree Repository**: Creates and manages OSTree repositories
- ✅ **Composefs Support**: Efficient container filesystem mounting
- ✅ **Initramfs Creation**: Uses dracut to create bootc-aware initramfs
- ✅ **Bootloader Support**: GRUB and systemd-boot installation
- ✅ **UEFI/BIOS Support**: Both UEFI and BIOS boot modes
- ✅ **Secure Boot**: Optional secure boot configuration
- ✅ **Cloud Integration**: AWS, Azure, GCP optimizations
## Installation
### Prerequisites
You need the following tools installed on your system:
```bash
# Container runtime
sudo apt install podman
# Disk image tools
sudo apt install qemu-utils parted
# OSTree and composefs
sudo apt install ostree libostree-dev
# Bootloader tools
sudo apt install grub-efi-amd64 systemd-boot
# Initramfs tools
sudo apt install dracut
# Build tools
sudo apt install build-essential
```
### Build from Source
```bash
git clone https://github.com/apt-ostree/bootc-image-builder
cd bootc-image-builder
cargo build --release
sudo cp target/release/bootc-image-builder /usr/local/bin/
```
## Usage
### Basic Usage
```bash
# Convert a bootc container image to QCOW2
bootc-image-builder build localhost/my-debian-server:latest --format qcow2
# Convert to raw disk image
bootc-image-builder build localhost/my-debian-server:latest --format raw --output my-server.img
# Convert to VMDK for VMware
bootc-image-builder build localhost/my-debian-server:latest --format vmdk --output my-server.vmdk
```
### Advanced Usage
```bash
# Build with custom settings
bootc-image-builder build localhost/my-debian-server:latest \
--format qcow2 \
--size 20 \
--arch x86_64 \
--bootloader grub \
--secure-boot \
--kernel-args "console=ttyS0,115200n8 quiet" \
--output my-server.qcow2
# Build for cloud deployment
bootc-image-builder build localhost/my-debian-server:latest \
--format ami \
--cloud-provider aws \
--output my-server-ami
```
### Command Line Options
```bash
bootc-image-builder build [OPTIONS] <IMAGE>
Arguments:

--bios Enable BIOS boot (default: auto-detect)
--kernel-args <KERNEL_ARGS> Custom kernel command line arguments [default: "console=ttyS0,115200n8 quiet"]
--cloud-provider <CLOUD_PROVIDER> Cloud provider for cloud-specific optimizations [possible values: aws, azure, gcp]
-h, --help Print help
-V, --version Print version
```
## How It Works
The bootc-image-builder follows this workflow:
1. **Pull and Extract**: Downloads and extracts the bootc container image
2. **Setup Bootc Support**: Installs bootc binary and configuration
3. **Create OSTree Repository**: Sets up OSTree repository structure
4. **Configure Composefs**: Enables composefs for efficient container mounting
5. **Create Initramfs**: Uses dracut to create bootc-aware initramfs
6. **Install Bootloader**: Installs GRUB or systemd-boot
7. **Create Disk Image**: Partitions, formats, and copies files to disk image
## Examples
### Building a Debian Server Image
```bash
# 1. Create a bootc container image with apt-ostree
apt-ostree compose tree debian-server.yaml --container
# 2. Convert to bootable disk image
bootc-image-builder build localhost/debian-server:latest \
--format qcow2 \
--size 10G \
--bootloader grub
# 3. Boot in QEMU
qemu-system-x86_64 -drive file=debian-server.qcow2,format=qcow2
```
### Building a Cloud Image
```bash
# 1. Create cloud-optimized bootc image
apt-ostree compose tree cloud-server.yaml --container
# 2. Convert to AMI format
bootc-image-builder build localhost/cloud-server:latest \
--format ami \
--cloud-provider aws \
--size 8G
# 3. Deploy to AWS
aws ec2 run-instances --image-id ami-12345678 --instance-type t3.micro
```
## Architecture Support
- **x86_64**: Intel/AMD 64-bit (default)
- **aarch64**: ARM 64-bit
- **ppc64le**: PowerPC 64-bit
## Format Support
- **QCOW2**: QEMU, KVM, OpenStack (default)
- **Raw**: Direct disk images
- **VMDK**: VMware compatibility
- **ISO**: Bootable CDs/DVDs
- **AMI**: Amazon Web Services
## Bootloader Support
- **GRUB**: Traditional bootloader with BLS support
- **systemd-boot**: Modern UEFI bootloader
## Security Features
- **Secure Boot**: UEFI secure boot support
- **Immutable**: Read-only filesystem by default
- **Atomic Updates**: OSTree-based atomic updates
- **Container Isolation**: Container-based system management
## Troubleshooting
### Common Issues
1. **Permission Denied**: The tool requires root/sudo privileges for disk operations
2. **Missing Dependencies**: Ensure all required tools are installed
3. **Dracut Failures**: Falls back to minimal initramfs if dracut fails
4. **Loop Device Issues**: May need to unmount existing loop devices
### Debug Mode
```bash
# Enable debug logging
RUST_LOG=debug bootc-image-builder build localhost/my-image:latest
```
