# ubuntu-firecracker

Docker container to build a linux kernel and ext4 rootfs compatible with [firecracker](https://github.com/firecracker-microvm/firecracker).

## Usage

Build the container:

```shell

docker build -t ubuntu-firecracker .

```

Build the image:

```shell

docker run --privileged -it --rm -v $(pwd)/output:/output ubuntu-firecracker

```

Start the image with firectl

```shell

# copy image and kernel

cp output/vmlinux ubuntu-vmlinux

cp output/image.ext4 ubuntu.ext4

# resize image

truncate -s 5G ubuntu.ext4

resize2fs ubuntu.ext4

#launch firecracker

firectl --kernel=ubuntu-vmlinux --root-drive=ubuntu.ext4 --kernel-opts="init=/bin/systemd noapic reboot=k panic=1 pci=off nomodules console=ttyS0"

```

I (bkleiner) have stopped using firecracker a while ago.
