Yes, this should be possible, evolution-api comes with a Dockerfile included. For a proper setup you also need redis & postgresql, best to start with the provided docker-compose as starting point how to wire things up:

Hello,

Possible, yes, permitted, no.

If you are using it for WhatsApp, that would not be allowed, using anything other than Meta's official API would count as a userbot, and thus, not be allowed on this platform.

It is also disallowed by Meta, so it would be by extension disallowed by Railway.

Please find somewhere else to run unofficial WhatsApp bots, because it is a bannable offense.

Thank you for understanding.

Best,

Brody
