How to Deploy or Integrate n8n on Microsoft Azure

Introduction

Automation is the backbone of modern digital business. It helps reduce manual tasks, improve accuracy, and speed up processes. Among the many tools available, n8n stands out as a powerful, open-source workflow automation platform. It allows you to connect apps and services with custom logic—whether you want to automate data movement, integrate APIs, or build complex event-driven processes.

But building your automation on your local machine is limiting, especially as workflows grow and require higher availability. This is where Microsoft Azure, one of the leading cloud platforms, enters the picture. Azure provides a robust and secure environment to host your n8n workflows with benefits like scalable infrastructure, enterprise-grade security, and a broad ecosystem of managed services.

This blog post will walk you through various ways to deploy n8n on Azure—from simple Virtual Machines to containerized services and Kubernetes. We’ll also cover how to secure your setup, integrate with Azure native services, and monitor for smooth operations.

Whether you’re a developer, IT professional, or automation enthusiast, this guide offers practical insights to get your n8n workflows running reliably in the cloud.

Prerequisites

Before you get your hands dirty with deployment, let’s outline the prerequisites.

Azure Account

You’ll need an Azure account to create resources. If you don’t have one, Microsoft offers a free tier with $200 in credits for the first 30 days and access to free services like Azure App Service, Azure Functions, and storage. This is perfect for experimenting.

Basic Knowledge of n8n and Docker

n8n is often deployed in Docker containers for easy packaging and portability. If you’re new to Docker, familiarize yourself with key concepts like images, containers, volumes, and environment variables. The official Docker documentation is an excellent resource.

Azure CLI or Azure Portal Access

You can manage Azure resources via the Azure Portal (a graphical web interface) or the Azure CLI (command line). For automation and scripting, the CLI is preferred, but beginners may find the Portal easier to navigate.

Optional: Custom Domain and SSL Certificate

For production-grade deployments, using a custom domain with HTTPS is critical to establish trust and secure data in transit. Azure provides built-in support for binding custom domains and managing SSL certificates, either via Azure-managed certificates or third-party providers.

Deployment Options Overview

There’s no one-size-fits-all when deploying n8n on Azure. Your choice depends on scale, maintenance preferences, and technical skill. Here’s a deeper look at each option.

1. Azure Virtual Machines (VMs)

This is the most traditional approach. You get a full virtual server where you control the OS, installed software, and network settings.

  • Pros:
    • Full customization and control.
    • Can run multiple services alongside n8n.
    • Suitable for small teams or proof of concepts.
  • Cons:
    • You are responsible for OS updates, Docker upgrades, backups, and security patches.
    • Scaling requires manual intervention (add more VMs/load balancers).

2. Azure App Service (Web App for Containers)

Azure App Service lets you deploy containerized apps without managing infrastructure.

  • Pros:
    • Fully managed with auto-scaling.
    • Integrated CI/CD pipeline support.
    • Easy setup for HTTPS and custom domains.
    • Great for teams wanting cloud-native simplicity.
  • Cons:
    • Some limitations on custom OS tweaks.
    • Storage options require Azure Files or external DBs for persistence.

3. Azure Container Instances (ACI)

ACI allows you to run containers without servers or clusters.

  • Pros:
    • Fast deployment and no VM management.
    • Pay per second for compute usage.
    • Good for burst workloads or testing.
  • Cons:
    • No built-in load balancing or autoscaling.
    • Limited network and domain configuration options.

4. Azure Kubernetes Service (AKS)

AKS is a managed Kubernetes service for container orchestration.

  • Pros:
    • Enterprise-grade scalability and flexibility.
    • Supports complex deployments and microservices.
    • Autoscaling and high availability features.
  • Cons:
    • Steeper learning curve.
    • More operational overhead and cost.
    • Requires knowledge of Kubernetes concepts.

Deploying n8n Using Azure Virtual Machines

Why choose VMs?

Azure VMs offer the flexibility of running a dedicated server where you can install software exactly the way you want. For n8n, this means you can run it inside Docker containers or even directly on the OS. This method is great if you want full control or want to integrate n8n tightly with other server applications.

Step 1: Create a VM

  • Go to the Azure Portal and create a new VM. Choose Ubuntu 20.04 LTS or Debian as your OS for better Docker support.
  • Select a VM size based on your expected workload (Standard B1s is a good starting point).
  • Configure networking to allow inbound traffic on the port n8n will use (default: 5678).

Step 2: Install Docker and Docker Compose

SSH into your VM and install Docker:

Bash
sudo apt update
sudo apt install -y docker.io docker-compose
sudo systemctl start docker
sudo systemctl enable docker

Make sure your user has permission to run Docker commands:

Bash
sudo usermod -aG docker $USER

Log out and back in to apply the group changes.

Step 3: Create a docker-compose.yml file

Here’s a simple example:

YAML
version: "3"

services:
  n8n:
    image: n8nio/n8n
    ports:
      - "5678:5678"
    volumes:
      - ./n8n-data:/home/node/.n8n
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=admin
      - N8N_BASIC_AUTH_PASSWORD=yourpassword
      - DB_TYPE=sqlite

This sets up n8n with basic authentication and SQLite as a default lightweight database.

Run the container:

Bash
docker-compose up -d

Step 4: Open necessary ports

Ensure that port 5678 is open in the Azure Network Security Group associated with your VM.

Step 5: Set up a reverse proxy (NGINX) for HTTPS

Install NGINX:

Bash
sudo apt install nginx

Configure it as a reverse proxy with SSL termination. Use Let’s Encrypt for free SSL certificates:

Bash
sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d yourdomain.com

Your NGINX config will proxy traffic from port 443 to 5678 internally.

Step 6: Add persistence and environment variables

Persist data in ./n8n-data to keep workflows and credentials safe across container restarts.

You can also connect n8n to external databases like PostgreSQL or MySQL for production reliability:

YAML
environment:
  - DB_TYPE=postgresdb
  - DB_POSTGRESDB_HOST=your_postgres_host
  - DB_POSTGRESDB_PORT=5432
  - DB_POSTGRESDB_DATABASE=n8n
  - DB_POSTGRESDB_USER=n8nuser
  - DB_POSTGRESDB_PASSWORD=yourpassword

Deploying n8n on Azure App Service (Web App for Containers)

Why Azure App Service?

This PaaS offering removes the need to manage VMs or containers yourself. Azure handles infrastructure, OS patches, and scaling automatically. It’s perfect for developers who want to focus on automation logic.

Step 1: Create an App Service

  • In the Azure Portal, create a new Web App.
  • Choose Docker Container as the publish method.
  • Select Linux as the OS.

Step 2: Use n8n’s official Docker image

Configure the container settings to use:

Plaintext
n8nio/n8n:latest

You can also use tags to control the version.

Step 3: Configure environment variables

Under Configuration → Application settings, set your variables:

  • N8N_BASIC_AUTH_ACTIVE = true
  • N8N_BASIC_AUTH_USER = admin
  • N8N_BASIC_AUTH_PASSWORD = yourpassword
  • DB_TYPE = postgresdb (if using external database)
  • Other n8n environment variables as needed.

Step 4: Persistent storage

App Service supports mounting Azure Files for persistent volumes, or you can connect n8n to an external managed database (Azure Database for PostgreSQL/MySQL).

Step 5: Use staging slots

Use deployment slots to test new versions before swapping into production. This reduces downtime and errors.

Step 6: Bind custom domain and enable HTTPS

App Service makes it easy to add custom domains and manage SSL certificates via the TLS/SSL settings tab. Azure provides free SSL certs managed automatically.

Deploying n8n via Azure Container Instances (ACI)

Why use ACI?

ACI lets you run containers instantly, without managing servers or clusters. It’s ideal for development, proof of concepts, or workloads with irregular demand.

Step 1: Create a Container Instance

Use the Azure CLI:

Bash
az container create \
  --resource-group myResourceGroup \
  --name n8nContainer \
  --image n8nio/n8n \
  --ports 5678 \
  --dns-name-label myn8ninstance

Step 2: Mount Azure File Share

Create an Azure File Share and mount it to /home/node/.n8n to persist workflow data.

Step 3: Set environment variables

Set authentication and database connection variables using --environment-variables option in CLI.

Step 4: Understand limitations

ACI doesn’t support built-in domain binding or SSL. To provide HTTPS, you can front your ACI with Azure Application Gateway or Azure Front Door.

Deploying n8n with Azure Kubernetes Service (AKS)

Why AKS?

For enterprise use cases, where reliability, scaling, and microservice architectures matter, AKS is the best choice. It’s a managed Kubernetes cluster with integration into Azure services.

Step 1: Set up AKS cluster

Create a cluster via CLI:

Bash
az aks create \
  --resource-group myResourceGroup \
  --name myAKSCluster \
  --node-count 3 \
  --enable-addons monitoring \
  --generate-ssh-keys

Step 2: Deploy n8n with Helm or YAML

Use Helm charts to simplify deployment:

Bash
helm repo add n8n https://helm.n8n.io/
helm install my-n8n n8n/n8n

Alternatively, define your own Kubernetes deployment and service YAML manifests.

Step 3: Use Persistent Volumes

Configure Persistent Volume Claims (PVCs) backed by Azure Disks or Files to store n8n data reliably.

Step 4: Configure Ingress

Set up an Ingress controller (NGINX or Traefik) to route traffic and terminate SSL:

YAML
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: n8n-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    cert-manager.io/cluster-issuer: letsencrypt-prod
spec:
  tls:
  - hosts:
    - yourdomain.com
    secretName: tls-secret
  rules:
  - host: yourdomain.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: n8n-service
            port:
              number: 5678

Step 5: Autoscaling and Monitoring

Enable Horizontal Pod Autoscaler (HPA) to automatically scale pods based on CPU or custom metrics.

Use Azure Monitor and Container Insights to collect logs and metrics.

Securing Your n8n Instance

Security is a top priority when running any web service, especially one automating workflows with potential access to sensitive data.

Authentication

Enable Basic Auth as a simple first step, or OAuth2 for more advanced use cases. Set strong passwords or integrate with Azure Active Directory for enterprise scenarios.

HTTPS

Always encrypt traffic. Use Let’s Encrypt certificates or Azure-managed certificates to enable HTTPS.

Reverse Proxy

Deploy NGINX or Traefik as a reverse proxy to handle SSL termination and improve security with rate limiting, IP whitelisting, and request filtering.

Network Restrictions

Limit access with Azure Network Security Groups or Azure Firewall to allow only trusted IP ranges.

Integrating n8n with Azure Services

n8n’s strength is connecting apps and services. When deployed on Azure, you can leverage native connectors.

  • Azure Blob Storage: Store files directly from workflows.
  • Cosmos DB: Access NoSQL databases for flexible data storage.
  • Azure Functions: Trigger serverless compute tasks.
  • Azure Logic Apps: Combine n8n with Microsoft’s native workflow engine for hybrid scenarios.
  • Azure Event Grid: React to cloud events in real time.

Example Use Case: Automatically upload email attachments to Azure Blob Storage and trigger an Azure Function to process files.

Monitoring and Scaling

Running workflows reliably means watching your system and adjusting resources as needed.

Monitoring

Azure Monitor provides logs, metrics, and alerts for all Azure resources. Connect n8n logs to Log Analytics for deep diagnostics.
