+# Dgraph Standalone Deployment On Render Guide
+
+This guide walks you through deploying Dgraph as a self-hosted solution on Render using the Dgraph standalone Docker image.
+
+## Prerequisites
+
+- A Render account (free tier available)
+- Basic familiarity with Docker
+- Git repository for your deployment configuration
+
+## Overview
+
+Dgraph is a distributed graph database that can be deployed in standalone mode for development and smaller production workloads. Render's container service provides an excellent platform for hosting Dgraph with persistent storage.
+
+## Step 1: Prepare Your Repository
+
+Create a new Git repository with the following structure:
+
+```
+dgraph-render/
+├── Dockerfile
+├── dgraph-config.yml
+├── start.sh
+└── README.md
+```
+
+### Create the Dockerfile
+
+```dockerfile
+FROM dgraph/standalone:latest
+
+# Create directories for data and config
+RUN mkdir -p /dgraph/data /dgraph/config
+
+# Copy configuration files
+COPY dgraph-config.yml /dgraph/config
+
+# Set working directory
+WORKDIR /dgraph
+
+# Expose the Dgraph ports
+EXPOSE 8080 9080 8000
+
+# Start Dgraph in standalone mode
+ADD start.sh /
+RUN chmod +x /start.sh
+
+CMD ["/start.sh"]
+```
+
+### Create the Configuration File
+
+Create `dgraph-config.yml`:
+
+```yaml
+# Dgraph configuration for standalone deployment
+
+datadir: /dgraph/data
+bindall: true
+
+# HTTP & GRPC ports
+port_offset: 0
+grpc_port: 9080
+http_port: 8080
+
+# Alpha configuration
+alpha:
+  lru_mb: 1024
+
+# Security settings (adjust as needed)
+whitelist: 0.0.0.0/0
+
+# Logging
+logtostderr: true
+v: 2
+
+# Performance tuning for cloud deployment
+badger:
+  compression: snappy
+  numgoroutines: 8
+```
+
+## Create start.sh
+
+```bash
+#!/bin/bash
+
+# Start Dgraph Zero
+dgraph zero --config /dgraph/config/dgraph-config.yml &
+
+# Start Dgraph Alpha
+dgraph alpha --config /dgraph/config/dgraph-config.yml &
+
+# Wait for all processes to finish
+wait
+```
+
+## Step 2: Deploy to Render
+
+### Using the Render Dashboard
+
+1. **Login to Render** and click "New +" → "Web Service"
+
+![Render Web Service](/images/dgraph/guides/render/render-web-service.png)
+
+2. **Connect Repository**: Connect your Git repository containing the Dockerfile
+
+![Render Git](/images/dgraph/guides/render/render-git.png)
+
+3. **Configure Service Settings**:
+   - **Name**: `dgraph-standalone`
+   - **Region**: Choose your preferred region
+   - **Branch**: `main` (or your default branch)
+   - **Runtime**: `Docker`
+   - **Build Command**: Leave empty (Docker handles this)
+   - **Start Command**: Leave empty (handled by Dockerfile CMD)
+
+![Render Configure](/images/dgraph/guides/render/render-configure.png)
+
+4. **Environment Settings**:
+   - **Instance Type**: Choose based on your needs (Starter for testing, Standard+ for production)
+   - **Scaling**: Set to 1 instance (Dgraph standalone doesn't support horizontal scaling)
+
+![Render Instance Type](/images/dgraph/guides/render/render-instance-type.png)
+
+5. Set `PORT` environment variable
+
+Our Render application exposes a single port which we must specify in an environment variable. We'll expose Dgraph's HTTP port 8080 by setting the `PORT` environment variable to 8080
+
+![Render Environment Variable](/images/dgraph/guides/render/render-env-var.png)
+
+6. Deploy
+
+![Deployed Render](/images/dgraph/guides/render/dgraph-render-deploy.png)
+
+## Step 3: Configure Persistent Storage
+
+Render provides persistent disks for data storage:
+
+1. **In Dashboard**: Go to your service → "Settings" → "Disks"
+2. **Add Disk**:
+   - **Name**: `dgraph-data`
+   - **Mount Path**: `/dgraph/data`
+   - **Size**: Start with 10GB, scale as needed
+
+3. **Redeploy** your service to apply disk changes
+
+## Step 4: Access Your Dgraph Instance
+
+Once deployed, your Dgraph instance will be available at: `https://your-service-name.onrender.com`
+
+## Step 5: Initial Setup and Testing
+
+### Test the Connection
+
+```bash
+# Health check
+curl https://your-service-name.onrender.com:8080/health
+
+# State endpoint
+curl https://your-service-name.onrender.com:8080/state
+```
+
+## Security Considerations
+
+### 1. Authentication Setup
+
+For production deployments, enable authentication:
+
+```yaml
+# Add to dgraph-config.yml
+security:
+  whitelist: "your-allowed-ips/32"
+  
+# Enable ACLs (Access Control Lists)
+acl:
+  enabled: true
+  secret_file: "/dgraph/config/hmac_secret"
+```
+
+### 2. Environment Variables
+
+Set sensitive configuration via Render environment variables:
+
+```bash
+DGRAPH_ALPHA_SECURITY_WHITELIST=10.0.0.0/8,172.16.0.0/12,192.168.0.0/16
+DGRAPH_ALPHA_ACL_SECRET_FILE=/dgraph/config/hmac_secret
+```
+
+### 3. Network Security
+
+- Use Render's private networking for internal communication
+- Configure proper firewall rules in your application
+- Consider using Render's built-in SSL termination
+
+## Monitoring and Maintenance
+
+### Health Checks
+
+Render automatically monitors your service. Configure custom health checks:
+
+```yaml
+# In render.yaml
+healthCheckPath: /health
+```
+
+### Logging
+
+Access logs via Render dashboard or using their CLI:
+
+```bash
+# Install Render CLI
+npm install -g @render-com/cli
+
+# View logs
+render logs -s your-service-id
+```
+
+### Backups
+
+Implement regular backups using Dgraph's export feature:
+
+```bash
+# Create backup script
+#!/bin/bash
+curl -X POST https://your-service-name.onrender.com:8080/admin/export
+
+# Schedule via cron job or external service
+```
+
+## Scaling Considerations
+
+### Vertical Scaling
+
+- Monitor memory and CPU usage in Render dashboard
+- Upgrade instance type as needed
+- Increase disk size for growing datasets
+
+### Performance Tuning
+
+Optimize your `dgraph-config.yml`:
+
+```yaml
+# For better performance on Render
+alpha:
+  lru_mb: 2048  # Adjust based on instance memory
+  
+badger:
+  compression: snappy
+  numgoroutines: 16
+  
+# Connection limits
+grpc:
+  max_message_size: 4194304  # 4MB
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Service Won't Start**:
+   - Check Dockerfile syntax
+   - Verify port configuration
+   - Review logs in Render dashboard
+
+2. **Data Persistence Issues**:
+   - Ensure disk is properly mounted
+   - Check disk space usage
+   - Verify write permissions
+
+3. **Connection Problems**:
+   - Confirm port bindings (8080, 9080)
+   - Check firewall/security settings
+   - Verify service URL
