Never store sensitive credentials (passwords, API keys, tokens, etc.) in plain text within code repositories. This practice poses a significant security risk as it can lead to unauthorized access if the repository is compromised or accidentally made public.

Instead:

1. Use environment-specific configuration files that are excluded from version control
2. Implement secrets management tools or services
3. Use environment variables for runtime injection of sensitive values
4. Include commented placeholder examples in configuration templates

Example of good practice:

-DOCKERHUB_PULL_USERNAME=actual_username
-DOCKERHUB_PULL_PASSWORD=actual_password
-DOCKERHUB_PULL_EMAIL=actual_email@example.com
+# DOCKERHUB_PULL_USERNAME=your_username
+# DOCKERHUB_PULL_PASSWORD=your_password  
+# DOCKERHUB_PULL_EMAIL=your_email

Make sure to add these sensitive files to your .gitignore file and document the required environment variables in your project documentation.
