+# Docker Deployment Fixes Applied
+
+## Issues Found and Resolved
+
+### Issue 1: Missing `email-validator` Dependency ❌ → ✅
+
+**Error:**
+```
+ImportError: email-validator is not installed, run `pip install pydantic[email]`
+```
+
+**Root Cause:**
+- Pydantic uses email validation in user models
+- `email-validator` package was not in `requirements.txt`
+- Backend container failed to start properly
+
+**Fix Applied:**
+- Added `email-validator==2.1.1` to `backend/requirements.txt` (line 7)
+- Rebuilt backend container with new dependency
+- Verified package installation
+
+**File Modified:**
+```
+backend/requirements.txt
++ email-validator==2.1.1
+```

+
+### Issue 2: Deprecated `version` Attribute Warning ⚠️ → ✅
+
+**Warning:**
+```
+level=warning msg="docker-compose.yml: the attribute `version` is obsolete"
+```
+
+**Root Cause:**
+- Docker Compose v2 no longer requires the `version` field
+- Causes deprecation warnings during all docker compose commands
+
+**Fix Applied:**
+- Removed `version: '3.8'` line from `docker-compose.yml`
+- Cleaned up file to modern Docker Compose format
+
+**File Modified:**
+```
