What Railpack detects
Railpack inspects the repository and picks the build for Go; most projects need no configuration. A Dockerfile in the repository always wins.
- go.mod
- main package (
cmd/…or the root) - go.sum
- Builder
- Railpack (default)
- Start command
- ./main # the compiled binary
Derived by Railpack; override it in Settings → Deploy → Start command.
