+# BUILD-TIME vs RUNTIME Variables:
+# ─────────────────────────────────
+# • NEXT_PUBLIC_* variables are baked into the client bundle at BUILD time
+#   They must be provided as --build-arg when building the Docker image
+#
+# • All other variables are used at RUNTIME only
+#   They are loaded from the .env file by docker-compose
+#
+# Docker Deployment:
+# ──────────────────
+# 1. Build-time: Only NEXT_PUBLIC_* vars are needed (via --build-arg)
+# 2. Runtime: All vars are loaded from .env file on the server
+# 3. The .env file should exist at: /home/deploy/sites/klz-cables.com/.env
+#
+# Security:
+# ─────────
+# • NEVER commit .env files with real credentials to git
+# • Use Gitea/GitHub secrets for CI/CD workflows
+# • Store production .env file securely on the server only

+# Environment Variables Cleanup - Summary
+
+## What Was Done
+
+Cleaned up the fragile, overkill environment variable mess and replaced it with a simple, clean, robust **fully automated** system.
+
+## Changes Made
+
+### 1. Dockerfile ✅
+**Before**: 4 build args including runtime-only variables (SENTRY_DSN)
+**After**: 3 build args - only `NEXT_PUBLIC_*` variables that need to be baked into the client bundle
+
+```dockerfile
+# Only these build args now:
+ARG NEXT_PUBLIC_BASE_URL
+ARG NEXT_PUBLIC_UMAMI_WEBSITE_ID
+ARG NEXT_PUBLIC_UMAMI_SCRIPT_URL
+```
+
+### 2. docker-compose.yml ✅
+**Before**: 12+ individual environment variables listed
+**After**: Single `env_file: .env` directive
+
+```yaml
+app:
+  image: registry.infra.mintel.me/mintel/klz-cables.com:latest
+  env_file:
+    - .env  # All runtime vars loaded from here
+```
+
+### 3. .gitea/workflows/deploy.yml ✅
+**Before**: Passing 12+ environment variables individually via SSH command (fragile!)
+**After**: **Fully automated** - workflow creates `.env` file from Gitea secrets and uploads it
+
+```yaml
+# Before (FRAGILE):
+ssh root@alpha.mintel.me \
+  "MAIL_FROM='${{ secrets.MAIL_FROM }}' \
+   MAIL_HOST='${{ secrets.MAIL_HOST }}' \
+   ... (12+ variables) \
+   /home/deploy/deploy.sh"
+
+# After (AUTOMATED):
+# 1. Create .env from secrets
+cat > /tmp/klz-cables.env << EOF
+NODE_ENV=production
+NEXT_PUBLIC_BASE_URL=${{ secrets.NEXT_PUBLIC_BASE_URL }}
+# ... all other vars from secrets
+EOF
+
+# 2. Upload to server
+scp /tmp/klz-cables.env root@alpha.mintel.me:/home/deploy/sites/klz-cables.com/.env
+
+# 3. Deploy
+ssh root@alpha.mintel.me "cd /home/deploy/sites/klz-cables.com && docker-compose up -d"
+```
+
+### 4. New Files Created ✅
+
+- **`.env.production`** - Template for reference (not used in automation)
+- **`docs/DEPLOYMENT.md`** - Complete deployment guide
+- **`docs/SERVER_SETUP.md`** - Server setup instructions
+- **`docs/ENV_MIGRATION.md`** - Migration guide from old to new system
+
+### 5. Updated Files ✅
+
+- **`.env.example`** - Clear documentation of all variables with build-time vs runtime notes
+
+## Architecture
+
+### Build Time (CI/CD)
+```
+Gitea Workflow
+  ↓
+  Only passes NEXT_PUBLIC_* as --build-arg
+  ↓
+Docker Build
+  ↓
+  Validates env vars
+  ↓
+  Bakes NEXT_PUBLIC_* into client bundle
+  ↓
+Push to Registry
+```
+
+### Runtime (Production Server) - FULLY AUTOMATED
+```
+Gitea Secrets
+  ↓
+  Workflow creates .env file
+  ↓
+  SCP uploads to server
+  ↓
+  Secured (chmod 600, chown deploy:deploy)
+  ↓
+docker-compose.yml (env_file: .env)
+  ↓
+  Loads .env into container
+  ↓
+Application runs with full config
+```
+
+## Key Benefits
+
+### 1. Simplicity
+- **Before**: 15+ Gitea secrets, variables in 3+ places
+- **After**: All secrets in Gitea, automatically deployed
+
+### 2. Clarity
+- **Before**: Confusing duplication, unclear which vars go where
+- **After**: Clear separation - build args vs runtime env file
+
+### 3. Robustness
+- **Before**: Fragile SSH command with 12+ inline variables
+- **After**: Robust automated file generation and upload
+
+### 4. Security
+- **Before**: Secrets potentially exposed in CI logs
+- **After**: Secrets masked in logs, .env auto-secured on server
+
+### 5. Maintainability
+- **Before**: Update in 3 places (Dockerfile, docker-compose.yml, deploy.yml)
+- **After**: Update Gitea secrets only - deployment is automatic
+
+### 6. **Zero Manual Steps** 🎉
+- **Before**: Manual .env file creation on server (error-prone, can be forgotten)
+- **After**: **Fully automated** - .env file created and uploaded on every deployment
+
+## What You Need to Do
+
+### Required Gitea Secrets
+
+Ensure these secrets are configured in your Gitea repository:
+
+**Build-Time (NEXT_PUBLIC_*):**
+- `NEXT_PUBLIC_BASE_URL` - Production URL (e.g., `https://klz-cables.com`)
+- `NEXT_PUBLIC_UMAMI_WEBSITE_ID` - Umami analytics ID
+- `NEXT_PUBLIC_UMAMI_SCRIPT_URL` - Umami script URL
+
+**Runtime:**
+- `SENTRY_DSN` - Error tracking DSN
+- `MAIL_HOST` - SMTP server
+- `MAIL_PORT` - SMTP port (e.g., `587`)
+- `MAIL_USERNAME` - SMTP username
+- `MAIL_PASSWORD` - SMTP password
+- `MAIL_FROM` - Sender email
+- `MAIL_RECIPIENTS` - Recipient emails (comma-separated)
+
+**Infrastructure:**
+- `REGISTRY_USER` - Docker registry username
+- `REGISTRY_PASS` - Docker registry password
+- `ALPHA_SSH_KEY` - SSH private key for deployment server
+
+**Notifications:**
+- `GOTIFY_URL` - Gotify notification server URL
+- `GOTIFY_TOKEN` - Gotify application token
+
+### That's It!
+
+**No manual steps required.** Just push to main branch and the workflow will:
+1. ✅ Build Docker image with NEXT_PUBLIC_* build args
+2. ✅ Create .env file from all secrets
+3. ✅ Upload .env to server
+4. ✅ Secure .env file (600 permissions, deploy:deploy ownership)
+5. ✅ Pull latest image
+6. ✅ Deploy with docker-compose

+## Documentation
+
+- **[DEPLOYMENT.md](docs/DEPLOYMENT.md)** - Complete deployment guide
+- **[SERVER_SETUP.md](docs/SERVER_SETUP.md)** - Server setup instructions (mostly automated now)
+- **[ENV_MIGRATION.md](docs/ENV_MIGRATION.md)** - Migration from old to new system
+- **[.env.example](.env.example)** - Environment variables reference
+- **[.env.production](.env.production)** - Production template (for reference)
+
+## Troubleshooting
+
+### Deployment Fails
+
+1. **Check Gitea secrets** - Ensure all required secrets are set
+2. **Check workflow logs** - Look for specific error messages
+3. **SSH to server** - Verify .env file exists and has correct permissions
+4. **Check container logs** - `docker-compose logs -f app`
+
+### .env File Issues
+
+The workflow automatically:
+- Creates .env from secrets
+- Uploads to server
+- Sets 600 permissions
+- Sets deploy:deploy ownership
+
+If there are issues, check the workflow logs for the "📝 Preparing environment configuration" step.
+
+### Missing Environment Variables
+
+If a variable is missing:
+1. Add it to Gitea secrets
+2. Update `.gitea/workflows/deploy.yml` to include it in the .env generation
+3. Push to trigger new deployment
+
+---
+
+**Result**: Environment variable management is now simple, clean, robust, and **fully automated**! 🎉
+
+No more manual .env file creation. No more forgotten configuration. No more fragile SSH commands. Just push and deploy!

-# Deployment Guide
+# KLZ Cables - Deployment Guide
 
-This document describes the deployment setup for KLZ Cables website.
+This document explains the deployment process and environment variable management for the KLZ Cables application.
 
-## Automatic Deployment (Gitea Actions)
+## Table of Contents
 
-The project uses Gitea Actions for CI/CD. On every push to the `main` branch:
+- [Overview](#overview)
+- [Environment Variables](#environment-variables)
+- [Local Development](#local-development)
+- [Production Deployment](#production-deployment)
+- [Troubleshooting](#troubleshooting)
 
-1. **Build**: Docker image is built with platform `linux/arm64`
-2. **Push**: Image is pushed to `registry.infra.mintel.me/mintel/klz-cables.com:latest`
-3. **Deploy**: SSH connection to production server pulls and restarts containers
+## Overview
 
-### Workflow File
+The application uses a clean, robust, **fully automated** environment variable strategy:
 
-Location: `.gitea/workflows/deploy.yml`
+- **Build-time variables**: Only `NEXT_PUBLIC_*` variables are baked into the client bundle
+- **Runtime variables**: All other variables are loaded from `.env` file at runtime
+- **Fully automated**: `.env` file is automatically generated from Gitea secrets on every deployment
+- **No manual steps**: No need to manually create or update `.env` files on the server
+- **No duplication**: Single source of truth for each environment
 
-### Required Secrets
+### Architecture
 
-Configure these in your Gitea repository settings:

+
+## Production Deployment
+
+### Prerequisites
+
+1. **Server Setup**: Ensure the production server has:
+   - Docker and Docker Compose installed
+   - Traefik reverse proxy running
+   - Network `infra` created
+   - Project directory exists: `/home/deploy/sites/klz-cables.com`
+
+2. **Gitea Secrets**: Configure the following secrets in your Gitea repository:
+
+   **Registry Access:**
+   - `REGISTRY_USER` - Docker registry username
+   - `REGISTRY_PASS` - Docker registry password
+
+   **Build-Time Variables:**
+   - `NEXT_PUBLIC_BASE_URL` - Production URL (e.g., `https://klz-cables.com`)
+   - `NEXT_PUBLIC_UMAMI_WEBSITE_ID` - Umami analytics ID
+   - `NEXT_PUBLIC_UMAMI_SCRIPT_URL` - Umami script URL
+
+   **Runtime Variables:**
+   - `SENTRY_DSN` - Error tracking DSN
+   - `MAIL_HOST` - SMTP server
+   - `MAIL_PORT` - SMTP port
+   - `MAIL_USERNAME` - SMTP username
+   - `MAIL_PASSWORD` - SMTP password
+   - `MAIL_FROM` - Sender email
+   - `MAIL_RECIPIENTS` - Recipient emails (comma-separated)
+   - `REDIS_URL` - Redis connection URL
+   - `REDIS_KEY_PREFIX` - Redis key prefix
+
+   **Infrastructure:**
+   - `REGISTRY_USER` - Docker registry username
+   - `REGISTRY_PASS` - Docker registry password
+   - `ALPHA_SSH_KEY` - SSH private key for deployment server
+
+   **Notifications:**
+   - `GOTIFY_URL` - Gotify notification server URL
+   - `GOTIFY_TOKEN` - Gotify application token
+
+### Deployment Process
+
+The deployment is **fully automated** via Gitea Actions:
+
+1. **Trigger**: Push to `main` branch
+2. **Build**: Docker image is built with `NEXT_PUBLIC_*` build arguments
+3. **Push**: Image is pushed to private registry
+4. **Generate .env**: Workflow creates `.env` file from all Gitea secrets
+5. **Upload .env**: File is uploaded to server via SCP and secured (600 permissions)
+6. **Deploy**: SSH to server, pull image, and run docker-compose
+7. **Notify**: Send success/failure notification via Gotify
+
+**No manual steps required!** The `.env` file is automatically created and deployed on every push.
+
+### Manual Deployment
+
+If you need to deploy manually (not recommended - use the automated workflow):
+
+```bash
+# SSH to the server
+ssh root@alpha.mintel.me
 
 # Navigate to the project directory
 cd /home/deploy/sites/klz-cables.com
 
+# Ensure .env file exists (normally created by workflow)
+# If missing, you'll need to create it from Gitea secrets
+
 # Pull the latest image
-docker compose pull
+docker pull registry.infra.mintel.me/mintel/klz-cables.com:latest
 
-# Restart containers
-docker compose up -d --force-recreate --remove-orphans
+# Restart the services
+docker-compose down
+docker-compose up -d
 
-# Clean up old images
-docker image prune -f
+# Check logs
+docker-compose logs -f app
 ```
 
+**Note**: Manual deployment requires the `.env` file to exist. The automated workflow creates this file from Gitea secrets. If deploying manually, you'll need to create it yourself using [`.env.production`](.env.production) as a template.
+
 ## Troubleshooting
 
-### Workflow Not Triggering
-
-1. Check Gitea Actions is enabled in repository settings
-2. Verify the workflow file syntax
-3. Check runner availability with label `docker`
-
 ### Build Failures
 
-1. Check build logs in Gitea Actions tab
-2. Verify all secrets are configured correctly
-3. Ensure Dockerfile is valid
-
-### Deployment Failures
-
-1. Verify SSH key has correct permissions (600)
-2. Check deploy user has Docker permissions
-3. Verify registry credentials are correct
-4. Check server disk space: `df -h`
-
-### Container Issues
+**Problem**: Build fails with "Environment validation failed"
 
+**Solution**: Ensure all required `NEXT_PUBLIC_*` variables are provided as build arguments:
 ```bash
-# Check container status
-docker compose ps
-
-# View logs
-docker compose logs -f app
-docker compose logs -f varnish
-
-# Check health
-docker compose exec app wget -O- http://localhost:3000/health
+docker build \
+  --build-arg NEXT_PUBLIC_BASE_URL=https://klz-cables.com \
+  --build-arg NEXT_PUBLIC_UMAMI_WEBSITE_ID=your-id \
+  --build-arg NEXT_PUBLIC_UMAMI_SCRIPT_URL=https://analytics.infra.mintel.me/script.js \
+  -t klz-cables .
 ```
 
-## Architecture
+### Runtime Failures
 
-```
-Client
-  ↓
-Traefik (TLS termination, routing)
-  ↓
-Varnish (HTTP caching)
-  ↓
-Next.js App (port 3000)
-```
-
-### Services
-
-- **app**: Next.js application
-- **varnish**: HTTP cache layer
-- **traefik**: Reverse proxy (external network)
-
-### Domains
-
-- `klz-cables.com` - Production
-- `www.klz-cables.com` - Production (www)
-- `staging.klz-cables.com` - Staging
-
-## Environment Variables
-
-### Build-time (in Dockerfile/Workflow)

-```
-
-### Analytics
-
-- Umami: Configured via environment variables
-- Sentry/GlitchTip: Error tracking
-
-## Rollback
-
-To rollback to a previous version:
+**Problem**: Container starts but application crashes
 
+**Solution**: Check that the `.env` file exists and contains all required runtime variables:
 ```bash
 # On the server
-cd /home/deploy/sites/klz-cables.com
+cat /home/deploy/sites/klz-cables.com/.env
 
-# Pull a specific version (if tagged)
-docker pull registry.infra.mintel.me/mintel/klz-cables.com:TAG
-
-# Or rebuild from a specific commit
-# (requires access to the repository on the server)
-
-# Restart with the older image
-docker compose up -d --force-recreate
+# Check container logs
+docker-compose logs app
 ```
 
-## Performance
+### Missing Environment Variables
 
-### Cache Invalidation
+**Problem**: Features not working (email, analytics, etc.)
 
-Varnish caches static assets. To clear cache:
+**Solution**:
+1. Check that the secret is configured in Gitea
+2. Verify the workflow includes it in the `.env` generation (see `.gitea/workflows/deploy.yml`)
+3. Redeploy to regenerate the `.env` file:
+   ```bash
+   git commit --allow-empty -m "Trigger redeploy"
+   git push origin main
+   ```
 
+4. Check the variable is loaded on the server:
+   ```bash
+   ssh root@alpha.mintel.me
+   cd /home/deploy/sites/klz-cables.com
+   docker-compose exec app env | grep VARIABLE_NAME
+   ```
+
+### Docker Compose Issues
+
+**Problem**: `docker-compose up` fails with "env file not found"
+
+**Solution**: The `.env` file should be automatically created by the workflow. If it's missing:
+1. Check the workflow logs for errors in the "📝 Preparing environment configuration" step
+2. Manually trigger a deployment by pushing to main
+3. If still missing, check server permissions and disk space
+
+### Network Issues
+
+**Problem**: Container can't connect to Traefik
+
+**Solution**: Verify the `infra` network exists:
 ```bash
-docker compose exec varnish varnishadm "ban req.url ~ ."
+docker network ls | grep infra
+docker network inspect infra
 ```
 
-### Cache Configuration
+## Security Best Practices
 
-Edit `varnish/default.vcl` and restart:
+1. **Never commit `.env` files** with real credentials to git
+2. **Use Gitea/GitHub secrets** for CI/CD workflows
+3. **Restrict SSH key access** to deployment server
+4. **Rotate credentials regularly** (SMTP passwords, API keys, etc.)
+5. **Use HTTPS** for all production URLs
+6. **Monitor logs** for suspicious activity
 
-```bash
-docker compose restart varnish
-```
+## Additional Resources
 
-## Security
-
-- All secrets are stored in Gitea repository settings
-- SSH key is injected at deployment time
-- Registry credentials are not stored in the repository
-- Deploy webhook requires secret token

+# Environment Variables Migration Guide
+
+This guide helps you migrate from the old fragile environment variable setup to the new clean, robust system.
+
+## What Changed?
+
+### Before (Fragile & Overkill)
+
+❌ **Problems:**
+- Environment variables passed individually via SSH (12+ vars)
+- Duplicate definitions in Dockerfile, docker-compose.yml, and deploy.yml
+- Build args included runtime-only variables (SENTRY_DSN, MAIL_*, REDIS_*)
+- No single source of truth
+- Difficult to maintain and error-prone
+
+```yaml
+# Old deploy.yml - FRAGILE!
+ssh root@alpha.mintel.me \
+  "MAIL_FROM='${{ secrets.MAIL_FROM }}' \
+   MAIL_HOST='${{ secrets.MAIL_HOST }}' \
+   MAIL_PASSWORD='${{ secrets.MAIL_PASSWORD }}' \
+   MAIL_PORT='${{ secrets.MAIL_PORT }}' \
+   MAIL_RECIPIENTS='${{ secrets.MAIL_RECIPIENTS }}' \
+   MAIL_USERNAME='${{ secrets.MAIL_USERNAME }}' \
+   NEXT_PUBLIC_BASE_URL='${{ secrets.NEXT_PUBLIC_BASE_URL }}' \
+   ... (12+ variables) \
+   /home/deploy/deploy.sh"
+```
+
+### After (Clean & Robust)
+
+✅ **Benefits:**
+- Single `.env` file on server contains all runtime variables
+- Only `NEXT_PUBLIC_*` variables passed as build args (3 vars)
+- Clear separation: build-time vs runtime
+- Easy to maintain and update
+- Single source of truth per environment
+
+```yaml
+# New deploy.yml - CLEAN!
+ssh root@alpha.mintel.me "/home/deploy/deploy.sh"
+```
+
+## Migration Steps
+
+### Step 1: Update Gitea Secrets
+
+**Remove these secrets** (no longer needed in CI/CD):
+- ❌ `MAIL_FROM`
+- ❌ `MAIL_HOST`
+- ❌ `MAIL_PASSWORD`
+- ❌ `MAIL_PORT`
+- ❌ `MAIL_RECIPIENTS`
+- ❌ `MAIL_USERNAME`
+- ❌ `NODE_ENV`
+- ❌ `REDIS_URL`
+- ❌ `REDIS_KEY_PREFIX`
+- ❌ `SENTRY_DSN` (from build args)
+
+**Keep these secrets** (still needed for build):
+- ✅ `NEXT_PUBLIC_BASE_URL`
+- ✅ `NEXT_PUBLIC_UMAMI_WEBSITE_ID`
+- ✅ `NEXT_PUBLIC_UMAMI_SCRIPT_URL`
+- ✅ `REGISTRY_USER`
+- ✅ `REGISTRY_PASS`
+- ✅ `ALPHA_SSH_KEY`
+- ✅ `GOTIFY_URL`
+- ✅ `GOTIFY_TOKEN`
+
+### Step 2: Create .env File on Server
+
+SSH to the production server and create the `.env` file:
+
+```bash
+ssh root@alpha.mintel.me
+
+# Create .env file
+cat > /home/deploy/sites/klz-cables.com/.env << 'EOF'
+# Application
+NODE_ENV=production
+NEXT_PUBLIC_BASE_URL=https://klz-cables.com
+
+# Analytics
+NEXT_PUBLIC_UMAMI_WEBSITE_ID=your-actual-id
+NEXT_PUBLIC_UMAMI_SCRIPT_URL=https://analytics.infra.mintel.me/script.js
+
+# Error Tracking
+SENTRY_DSN=your-actual-dsn
+
+# Email
+MAIL_HOST=smtp.eu.mailgun.org
+MAIL_PORT=587
+MAIL_USERNAME=your-actual-username
+MAIL_PASSWORD=your-actual-password
+MAIL_FROM=KLZ Cables <noreply@klz-cables.com>
+MAIL_RECIPIENTS=info@klz-cables.com
+
+# Redis
+REDIS_URL=redis://redis:6379/2
+REDIS_KEY_PREFIX=klz:
+
+# Varnish
+VARNISH_CACHE_SIZE=256m
+EOF
+
+# Secure the file
+chmod 600 /home/deploy/sites/klz-cables.com/.env
+chown deploy:deploy /home/deploy/sites/klz-cables.com/.env
+```
+
+**Important**: Replace all `your-actual-*` placeholders with real values from your old Gitea secrets.
+
+### Step 3: Update Deployment Script
+
+Update `/home/deploy/deploy.sh` to use the new approach:
+
+```bash
+cat > /home/deploy/deploy.sh << 'EOF'
+#!/bin/bash
+set -e
+
+PROJECT_DIR="/home/deploy/sites/klz-cables.com"
+
+echo "╔══════════════════════════════════════════════════════════════════════════════╗"
+echo "║ KLZ Cables - Deployment Script                                              ║"
+echo "╚══════════════════════════════════════════════════════════════════════════════╝"
+echo ""
+
+cd "$PROJECT_DIR"
+
+# Check if .env file exists
+if [ ! -f .env ]; then
+    echo "❌ ERROR: .env file not found at $PROJECT_DIR/.env"
+    exit 1
+fi
+
+echo "🔐 Logging into Docker registry..."
+echo "$REGISTRY_PASS" | docker login registry.infra.mintel.me -u "$REGISTRY_USER" --password-stdin
+
+echo "🔄 Pulling latest image..."
+docker pull registry.infra.mintel.me/mintel/klz-cables.com:latest
+
+echo "🔄 Stopping existing containers..."
+docker-compose down
+
+echo "🚀 Starting new containers..."
+docker-compose up -d
+
+echo "⏳ Waiting for services to be healthy..."
+sleep 10
+
+echo "🔍 Checking service status..."
+docker-compose ps
+
+echo ""
+echo "✅ Deployment complete!"
+EOF
+
+chmod +x /home/deploy/deploy.sh
+```
+
+### Step 4: Deploy Updated Code
+
+The new code is already in the repository. Just push to trigger deployment:
+
+```bash
+git push origin main
+```
+
+The CI/CD workflow will:
+1. Build with only `NEXT_PUBLIC_*` build args
+2. Push to registry
+3. SSH to server and run deploy.sh
+4. Deploy.sh will use the `.env` file for runtime vars
+
+### Step 5: Verify Migration
+
+After deployment, verify everything works:
+
+```bash
+# SSH to server
+ssh root@alpha.mintel.me
+
+# Check containers are running
+cd /home/deploy/sites/klz-cables.com
+docker-compose ps
+
+# Verify environment variables are loaded
+docker-compose exec app env | grep -E "NODE_ENV|NEXT_PUBLIC|MAIL|REDIS"
+
+# Check application logs
+docker-compose logs -f app
+
+# Test the website
+curl -I https://klz-cables.com
+```
+
+## Comparison Table
+
+| Aspect | Before | After |
+|--------|--------|-------|
+| **Gitea Secrets** | 15+ secrets | 8 secrets |
+| **Build Args** | 4 vars (including runtime-only) | 3 vars (NEXT_PUBLIC_* only) |
+| **Runtime Vars** | Passed via SSH command | Loaded from .env file |
+| **Maintenance** | Update in 3 places | Update in 1 place |
+| **Security** | Secrets in CI logs | Secrets only on server |
+| **Clarity** | Confusing duplication | Clear separation |
+| **Robustness** | Fragile SSH command | Robust file-based config |
+
+## Rollback Plan
+
+If you need to rollback to the old system:
+
+1. Revert the changes in git:
+   ```bash
+   git revert HEAD
+   git push origin main
+   ```
+
+2. Re-add the removed Gitea secrets
+
+3. The old deployment will work again
+
+## FAQ
+
+**Q: Why keep `NEXT_PUBLIC_*` in both build args and .env file?**
+
+A: `NEXT_PUBLIC_*` variables are special in Next.js - they're embedded into the JavaScript bundle at build time. They must be provided as build args. However, they're also needed at runtime for server-side rendering, so they're in the .env file too.
+
+**Q: Can I update environment variables without rebuilding?**
+
+A: Yes, for runtime-only variables (MAIL_*, REDIS_*, SENTRY_DSN, etc.). Just edit the `.env` file on the server and restart containers:
+```bash
+nano /home/deploy/sites/klz-cables.com/.env
+docker-compose down && docker-compose up -d
+```
+
+For `NEXT_PUBLIC_*` variables, you need to rebuild the Docker image since they're baked into the client bundle.
+
+**Q: Where should I store the .env file backup?**
+
+A: Keep a secure backup outside the server:
+```bash
+# Download from server
+scp root@alpha.mintel.me:/home/deploy/sites/klz-cables.com/.env \
+    ~/secure-backups/klz-cables.env.backup
+
+# Store in password manager or encrypted storage
+```
+
+**Q: What if I accidentally commit .env to git?**
+
+A: 
+1. Remove it immediately: `git rm .env && git commit -m "Remove .env"`
+2. Rotate all credentials in the file
+3. Update the `.gitignore` to ensure it doesn't happen again (already done)
+
+## Support
+
+If you encounter issues during migration:
+
+1. Check the logs: `docker-compose logs -f app`
+2. Verify .env file exists and has correct permissions
+3. Ensure all required variables are set
+4. Review [DEPLOYMENT.md](./DEPLOYMENT.md) for detailed troubleshooting
+
+## Summary
+
+The new system is:
+- ✅ **Simpler**: One .env file instead of scattered variables
+- ✅ **Cleaner**: Clear separation of build vs runtime
+- ✅ **Robust**: File-based config instead of fragile SSH commands
+- ✅ **Secure**: Secrets stay on server, not in CI logs
+- ✅ **Maintainable**: Single source of truth per environment
+
+You've successfully migrated from a fragile, overkill setup to a clean, production-ready configuration! 🎉

+# Server Setup Guide - KLZ Cables
+
+This guide explains how to set up the production environment on the deployment server.
+
+## Prerequisites
+
+- Server: `alpha.mintel.me`
+- User: `deploy` (with sudo access)
+- Docker and Docker Compose installed
+- Traefik reverse proxy running
+- External network `infra` created
+
+## Initial Server Setup
+
+### 1. Create Project Directory
+
+```bash
+# SSH to the server as root or deploy user
+ssh root@alpha.mintel.me
+
+# Create project directory
+mkdir -p /home/deploy/sites/klz-cables.com
+cd /home/deploy/sites/klz-cables.com
+```
+
+### 2. Create Environment File
+
+Create the `.env` file with production configuration:
+
+```bash
+# Create .env file from template
+cat > /home/deploy/sites/klz-cables.com/.env << 'EOF'
+# ============================================================================
+# KLZ Cables - Production Environment Configuration
+# ============================================================================
+
+# Application
+NODE_ENV=production
+NEXT_PUBLIC_BASE_URL=https://klz-cables.com
+
+# Analytics (Umami)
+NEXT_PUBLIC_UMAMI_WEBSITE_ID=your-umami-website-id
+NEXT_PUBLIC_UMAMI_SCRIPT_URL=https://analytics.infra.mintel.me/script.js
+
+# Error Tracking (GlitchTip/Sentry)
+SENTRY_DSN=https://your-sentry-dsn@errors.infra.mintel.me/project-id
+
+# Email Configuration (Mailgun)
+MAIL_HOST=smtp.eu.mailgun.org
+MAIL_PORT=587
+MAIL_USERNAME=your-mailgun-username
+MAIL_PASSWORD=your-mailgun-password
+MAIL_FROM=KLZ Cables <noreply@klz-cables.com>
+MAIL_RECIPIENTS=info@klz-cables.com
+
+# Redis Cache
+REDIS_URL=redis://redis:6379/2
+REDIS_KEY_PREFIX=klz:
+EOF
+```
+
+**Important**: Replace all placeholder values with actual production credentials.
+
+### 3. Secure the Environment File
+
+```bash
+# Set proper permissions (readable only by owner)
+chmod 600 /home/deploy/sites/klz-cables.com/.env
+
+# Verify ownership
+chown deploy:deploy /home/deploy/sites/klz-cables.com/.env
+
+# Verify permissions
+ls -la /home/deploy/sites/klz-cables.com/.env
+# Should show: -rw------- 1 deploy deploy
+```
+
+### 4. Create Docker Compose File
+
+```bash
+# Copy docker-compose.yml from repository
+# This should be done automatically by the deployment script
+# Or manually:
+cat > /home/deploy/sites/klz-cables.com/docker-compose.yml << 'EOF'
+services:

+
+### 5. Create Deployment Script
+
+```bash
+cat > /home/deploy/deploy.sh << 'EOF'

+
+cd "$PROJECT_DIR"
+
+# Check if .env file exists
+if [ ! -f .env ]; then
+    echo "❌ ERROR: .env file not found at $PROJECT_DIR/.env"
+    echo "Please create the .env file before deploying."
+    exit 1
+fi
+

+echo "  • Staging: https://staging.klz-cables.com"
+echo ""
+EOF
+
+# Make script executable
+chmod +x /home/deploy/deploy.sh
+```
+
+### 6. Configure Docker Registry Access
+
+The deployment script needs registry credentials. These are passed as environment variables from the CI/CD workflow:
+
+```bash
+# The workflow passes these variables:
+# REGISTRY_USER - from Gitea secrets
+# REGISTRY_PASS - from Gitea secrets
+```
+
+## Verification
+
+### Check Environment File
+
+```bash
+# Verify .env file exists and has correct permissions
+ls -la /home/deploy/sites/klz-cables.com/.env
+
+# Check content (be careful not to expose secrets in logs)
+head -n 5 /home/deploy/sites/klz-cables.com/.env
+```
+
+### Test Deployment Script
+
+```bash
+# Run deployment script manually (requires registry credentials)
+REGISTRY_USER=your-user REGISTRY_PASS=your-pass /home/deploy/deploy.sh
+```
+
+### Check Running Containers
+
+```bash
+cd /home/deploy/sites/klz-cables.com
+docker-compose ps
+docker-compose logs -f app
+```
+
+### Verify Environment Variables in Container
+
+```bash
+# Check that environment variables are loaded
+docker-compose exec app env | grep -E "NODE_ENV|NEXT_PUBLIC|MAIL|REDIS"
+```
+
+## Updating Environment Variables
+
+When you need to update environment variables:
+
+```bash
+# 1. SSH to the server
+ssh root@alpha.mintel.me
+
+# 2. Edit the .env file
+nano /home/deploy/sites/klz-cables.com/.env
+
+# 3. Restart the containers to pick up changes
+cd /home/deploy/sites/klz-cables.com
+docker-compose down
+docker-compose up -d
+
+# 4. Verify the changes
+docker-compose logs -f app
+```
+
+**Note**: Changes to `NEXT_PUBLIC_*` variables require rebuilding the Docker image, as they are baked into the client bundle at build time.
+
+## Troubleshooting
+
+### .env File Not Found
+
+```bash
+# Check if file exists
+ls -la /home/deploy/sites/klz-cables.com/.env
+
+# If missing, create it from template
+cp .env.production /home/deploy/sites/klz-cables.com/.env
+# Then edit with actual values
+```
+
+### Permission Denied
+
+```bash
+# Fix ownership
+chown -R deploy:deploy /home/deploy/sites/klz-cables.com
+
+# Fix .env permissions
+chmod 600 /home/deploy/sites/klz-cables.com/.env
+```
+
+### Container Won't Start
+
+```bash
+# Check logs
+docker-compose logs app
+
+# Check if .env is loaded
+docker-compose config
+
+# Verify environment variables
+docker-compose exec app env
+```
+
+### Network Issues
+
+```bash
+# Verify infra network exists
+docker network ls | grep infra
+
+# If missing, create it
+docker network create infra
+```
+
+## Security Checklist
+
+- [ ] `.env` file has `600` permissions (readable only by owner)
+- [ ] `.env` file is owned by `deploy:deploy`
+- [ ] `.env` file is NOT in git repository
+- [ ] All sensitive credentials are filled in
+- [ ] SSH keys are properly secured
+- [ ] Firewall rules are configured
+- [ ] HTTPS is enforced via Traefik
+- [ ] Regular backups of `.env` file are maintained
+
+## Backup
+
+Create a secure backup of the environment file:
+
+```bash
+# Backup .env file
+cp /home/deploy/sites/klz-cables.com/.env \
+   /home/deploy/backups/klz-cables.env.$(date +%Y%m%d)
+
+# Set proper permissions on backup
+chmod 600 /home/deploy/backups/klz-cables.env.*
+```
