Firecracker RootFS Builder
Firecracker RootFS handler is a simple project to create root-file-system with Docker images in ext4 format and allows you to run them in micro-vms by Firecracker.
## Features
- Convert Docker images to rootFS
- Store them locally (Registry soon ...)
## Installation
To install OpenMetricMigrator, clone the repository and build the project:
```sh
# Clone the repository
git clone https://github.com/WoodProgrammer/firecracker-rootfs-builder.git
cd firecracker-rootfs-builder
go build -o fco .
mv fco /usr/local/bin
```
## Usage
Run the tool with the required options:
```sh
cat <config.yaml
image: alpine
docker_file: Dockerfile
context: "."
target_directory: "alpine-rootfs"
EOF
```
```sh
./fco -C config.yaml
```
Config file contains docker image spec and rootfs details.Apart from these details you can basically pass the rootFS size and name as well. (Needs to improve)
### Available Flags
```sh
