Is there a way to reproduce Codeship's CI environment locally when not using Codeship's Docker support?
We don't share the build VMs for our classic infrastructure publicly at the moment. I'll bring this up with our engineering team, but I can't make any promises right now on what they'll decide.
We do however have a SSH debug feature available, that will allow you to access a build VM with your code cloned via SSH and run & tweak commands that way. See https://codeship.com/documentation/continuous-integration/ssh-access/ for more information.
