Security Review: Critical Configuration Vulnerabilities in Docker Compose

[youming1970]

Hi @naeemaei,

Thank you for creating this comprehensive Golang clean architecture example! It's a valuable learning resource for the community. However, I noticed several critical security configurations that could mislead developers learning from this project.

Critical Security Issues

P0: Database Security Exposure

Location: docker/docker-compose.yml:95, 111

POSTGRES_PASSWORD: admin              # Weak plaintext password
PGADMIN_DEFAULT_PASSWORD: 123456      # Extremely weak password

Risk: Complete database exposure with trivial credentials

Suggested Fix:

POSTGRES_PASSWORD: ${POSTGRES_PASSWORD:-}
PGADMIN_DEFAULT_PASSWORD: ${PGADMIN_PASSWORD:-}

P1: Personal Information Exposure

Location: docker/docker-compose.yml:110

PGADMIN_DEFAULT_EMAIL: h.naimaei@gmail.com

Risk: Personal email exposed in public repository

P1: Version Control Issues

image: postgres          # Missing version
image: redis:latest      # Unstable tag

Risk: Unpredictable deployments and potential compatibility issues

Impact Assessment

• Educational Risk: 326+ stars means many developers learn from this configuration
• Security Risk: Users might copy these patterns into production environments
• Community Impact: Opportunity to demonstrate security best practices

Suggested Improvements

1. Environment Variables: Move all sensitive configs to .env files
2. Version Pinning: Use specific image tags (e.g., postgres:15.4)
3. Network Security: Consider internal networking for database services
4. Documentation: Add security section in README

Educational Value

This could become an excellent example of secure Docker Compose configuration for the Go community. Would you be interested in implementing these security improvements?

The fixes are straightforward and would significantly improve the educational value of this project.

Best regards,
