Shell Scripts

Railpack can deploy applications that use shell scripts as their entry point.

Detection

Your project will be automatically detected as a shell script application if any of these conditions are met:

• A start.sh script exists in the root directory
• The RAILPACK_SHELL_SCRIPT environment variable is set to a valid script file

Script File

Create a shell script in your project root (e.g., start.sh):

#!/bin/bash

echo "Hello world..."
