How to get docker inside of a build?

Hi, I'm trying to deploy an iteration of https://github.com/engineer-man/piston

It requires docker as part of its normal operations to do sandboxed execution + at build time. Railway detects it as just a nodejs project and the build fails.

How can I resolve this?

this requires docker volumes, railway doesn't have docker volume support at the moment, so currently you won't be able to deploy that to railway
