Information by service

CapRover
Captain Definition File | CapRover Docs
Generate the following files captain-definition to apply the Dockerfile.

Fly

[[services]]
internal_port = 80
fly deploy often fails in my experience. For example, the builder is not ready or wget fails. That’s not the problem with this code. If you experience that, wait a while and try fly deploy again.
Railway
Exposing Your App | Railway Docs
Don’t be surprised if you get an application error on your first deploy.
Please re-deploy after putting PORT in the variable. Displayed after some time from deployment.
