Unable to run with jailer

[teticio]

I cannot figure out how to run with jailer and would be very grateful if someone could explain or - even better - point me to / put in a README. When I run a container, I get

noop operation returning shim dir for JailPath  jailer=noop runtime=aws.firecracker vmID=b4a7d532-2d98-43f7-ae7f-33cedfe63a96

I've tried adding the following to my firecracker-runtime.json file, but I don't really know what I am doing as I haven't managed to find any documentation. I have managed to run firecracker from jailer, but I would like to use firecracker-containerd if possible.

  "jailer": {
    "runc_binary_path": "/usr/bin/runc"
  }

Thanks in advance!
