Quick Fix: When using Windows notepad to modify initialization scripts for Postgres docker-compose, ensure the file format remains unchanged. Avoid using notepad, as it can alter the file format, leading to script read errors during container initialization.
The Problem:
When running Postgres docker-compose with initialization scripts, users encounter a ‘required file not found’ error, preventing the execution of scripts mounted in the ‘docker-entrypoint-initdb.d’ directory. Despite following the official documentation, the error persists, hindering the desired automated database dump.
The Solutions:
Solution 1: Fix File Format Issue
To resolve the "required file not found" error, ensure that the initialization scripts are in the correct format. The issue can arise if the scripts are modified using Windows Notepad, which may alter the file format and prevent Docker from reading them correctly.
To fix this:
Use a plain text editor such as Notepad++ or vi to edit the scripts.
Save the scripts with the appropriate file extension (e.g., .sh).
Check if the files have any hidden characters or Unicode Byte Order Mark (BOM) that may interfere with Docker’s reading process.
