Ultimate Guide: Deploy n8n on Azure with OpenAI & Azure App Services (Step-by-Step)

With Automated Scripts & Visual Step-by-Step Instructions

In today’s automation-driven world, n8n has emerged as a powerful open-source workflow automation tool. When combined with Azure’s cloud capabilities and AI services, it becomes an enterprise-grade automation powerhouse. In this guide, I’ll show you how to deploy n8n on Azure App Service and integrate it with Azure OpenAI and Microsoft Outlook using automated scripts.

This comprehensive visual guide provides:

• One-click deployment scripts for all Azure resources
• Automated Outlook OAuth2 setup with permission configuration
• AI-powered workflow examples with Azure OpenAI
• Troubleshooting visual guides for common issues

Why Azure for n8n?

• Managed infrastructure: No server maintenance
• Seamless scaling: Handle workflow spikes effortlessly
• Enterprise security: Azure AD integration and compliance
• AI integration: Native access to Azure OpenAI
• Cost efficiency: Pay only for what you use

Prerequisites

1. Azure Account (Free $200 credit)

2. GitHub Account (For optional Codespaces deployment)

3. Azure CLI installed (instructions)
4. Basic terminal skills

Step 1: One-Click n8n Deployment on Azure [⚡️]

Our automated script handles:

• Azure login check
• Resource group creation
• Storage account provisioning
• App Service Plan and Web App deployment (Linux container with Docker)
• Configuration of required app settings (e.g., WEBSITES_PORT, AZURE_STORAGE_CONNECTION_STRING)
• Azure OpenAI resource creation with key and endpoint configuration
• Optional Outlook 365 OAuth2 setup (placeholder for integration)
• Web App restart and access summary

# Clone repository
git clone https://github.com/3tallah/n8n-azure-deployment.git
cd n8n-azure-deployment

# Make script executable
chmod +x n8n_deployment_script.sh

# Run the full deployment
bash deploy-n8n-azure.sh

✅ The script includes everything: resource group, storage, App Service, OpenAI service, app settings, Outlook OAuth2 support, and auto-restart

To configure in n8n:

1. Run the script and save credentials
2. Wait 10 minutes and visit the n8n Azure app services link

Step 3: Creating AI-Powered Workflows [🧠]

Now let’s create a workflow that uses Azure OpenAI to process emails:

// Sample workflow JSON
{
  "nodes": [
    {
      "type": "microsoftOutlook",
      "action": "getMessages",
      "credentials": "Microsoft Outlook OAuth2 API"
    },
    {
      "type": "httpRequest",
      "url": "={{ $env.AZURE_OPENAI_ENDPOINT }}/completions",
      "method": "POST",
      "headers": {
        "api-key": "={{ $env.AZURE_OPENAI_API_KEY }}"
      },
      "body": {
        "model": "text-davinci-003",
        "prompt": "Summarize this email: {{ $node.first.json.body }}",
        "max_tokens": 150
      }
    },
    {
      "type": "slack",
      "channel": "#alerts",
      "text": "New email summary: {{ $node.second.json.choices[0].text }}"
    }
  ]
}

This workflow:

1. Checks Outlook for new emails
2. Sends email content to Azure OpenAI
3. Posts summary to Slack

Benefits of This Setup

1. Persistent storage: Workflows survive restarts
2. Auto-scaling: Handle traffic spikes
3. Enterprise security: Azure AD integration
4. Cost control: Pay-per-use pricing
5. AI integration: Access to latest OpenAI models

Troubleshooting Tips

1. Long initial startup (5-7 minutes) – Azure pulls container image
2. Check logs:

   az webapp log tail --name <app-name> --resource-group n8n-resources
   

3. Verify permissions – Ensure admin consent is granted
4. Storage issues – Confirm APP_SERVICE_STORAGE=true is set
