Good article. Firecracker is something that has definitely piqued my interest when it comes to quickly spinning up a throwaway environment to use for either development or CI. I run a CI platform [1], which currently uses QEMU for the build environments (Docker is also supported but currently disabled on the hosted offering), startup times are ok, but having a boot time of 1-2s is definitely highly appealing. I will have to investigate Firecracker further to see if I could incorporate this into what I'm doing.

Julia Evans has also written about Firecracker in the past too [2][3].

Thanks for commenting, and your product looks cool btw.

Yeah a lot of people have talked about Firecracker in the past, that's why I focus on the pain and the problem being solved. The tech is cool, but it's not the only thing that matters.

People need to know that there are better alternatives to sharing a docker socket or using DIND with K8s runners.
