Super interesting read!
I’ve been playing with Firecracker on a Raspberry Pi 4, but never could get Docker inside a Firecracker uVM to work. Should this be supported at all?
- vbitz 4y agoDepends how your starting the VM. I’ve run Docker on Firecracker with a Raspberry PI 4 before but it needed some fixes. One possibly is if your running directly from a Initramfs without a block device then docker needs DOCKER_RAMDISK set as a environment variable. Otherwise it’s possible the minimal kernel your Firecracker config uses doesn’t support it out of the box. You can use a regular kernel but you need to make sure modules can be loaded from somewhere.
- weejewel 4y agoThanks for your reply! Do you have a guide or more information somewhere? I found that while Firecracker seems popular, it's sparsely documented.
