Subject: [PATCH] Comprehensive fix for Docker static files permission issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Problem Analysis:
- Static files collection failing with permission errors in Docker containers
- Non-root user cannot create directories in container filesystem
- Previous fix didn't handle runtime permission management properly

## Comprehensive Solution:

### 1. Enhanced Dockerfile:
- Added `gosu` package for secure user switching
- Removed premature USER directive - run setup as root first
- Improved directory permissions with proper chmod/chown

### 2. Robust Entrypoint Script:
- Runs initial setup (migrations, static collection) as root
- Explicitly sets directory permissions for static/media files
- Uses `gosu` to securely switch to django user for main application
- Ensures proper ownership before application starts

### 3. Updated Docker Compose Volume:
- Changed volume mapping to use ../files/staticfiles (more descriptive)
- Ensures persistent storage for static files across deployments

## Security & Best Practices:
- ✅ Maintains security with non-root application runtime
- ✅ Handles setup operations with necessary root permissions
- ✅ Uses gosu for secure user switching (better than su/sudo)
- ✅ Explicit permission management for container directories

## Benefits:
- Resolves all static files permission errors
- Works reliably in containerized environments
- Maintains security best practices
- Compatible with Dokploy and other orchestration platforms

This should completely resolve the collectstatic permission issues.
