Curious what prevented you from running docker in a microvm? I've successfully run docker in qemu and firecracker microvms.

So we originally just wanted the vm to be light-weight and can start fast, so we removed docker. @binsquare has a change later to add docker back.

I've been experimenting with krunvm and there the init system is weird. Didn't evaluate firecracker since it doesn't support macOS hosts.
