Hi @nyurik ,
My name is Veselina, I’m part of FlyCI - macOS runners for GitHub Actions and FlyCI Wingman - an AI assistent that suggest fixes to your failing builds. We currently do not have nginx embedded in the runner images, but we can add it if we find a common-case scenario.

We would be happy to discuss your specific needs and see how we can help. Feel free to contact us at contact@flyci.net.
