Firecracker MicroVMs

Best example of current usage that comes to mind (outside of AWS’s own Lambda & Fargate) is Fly.io - they they use Firecracker for all the containers.

For those using firecracker, what's your method for building a rootfs?

I build them from docker images: https://blog.davidv.dev/docker-based-images-on-baremetal.htm...

Does anyone know of any good orchestrators for Firecracker VMs? While the technology is great, the CLI and API are still a bit too complex and low-level to implement some basic use cases in production.

Take a look at Weaveworks Ignite for an open source tool for running Firecracker VMs from container images: https://github.com/weaveworks/ignite

And of course AWS Fargate and Lambda use this tech under the hood transparently, so that's always an option if you don't want to host and operate it yourself.
