Deploying n8n with Docker: From Local Setups to a Radically Simple Cloud Alternative

Self-hosting the open-source automation platform n8n offers total control over your data, workflows, and costs. Docker provides the obvious path—a clean, isolated environment to run your instance. But this path is littered with hidden operational traps. The power of Docker often comes with a steep cost in complexity, from managing container configurations and databases to orchestrating updates and ensuring high availability.

This tax on productivity slows down even experienced developers.

This guide walks you through the standard methods for running n8n locally with Docker, covering the quick-start docker run command and a more robust docker compose setup. More importantly, it introduces a modern, cloud-native approach that gives you all the benefits of self-hosting without the operational headaches.

Why Self-Host n8n with Docker?

Before diving into the "how," let's anchor the "why." Using Docker to run your own n8n instance offers several key advantages:

• Data Sovereignty: Your workflow data, credentials, and execution logs remain entirely within your infrastructure.
• Cost-Effectiveness: Run n8n on hardware you already own or on cost-effective cloud virtual machines, avoiding subscription fees.
• Total Customization: You have complete control over n8n's configuration, environment variables, and versioning.
• Isolated Environment: Docker containers package n8n and its dependencies, preventing conflicts with other applications on your server.

Method 1: The Quick Start with docker run

The fastest way to get an n8n instance running is with a single docker run command. This method is ideal for testing, local development, or simple, single-user scenarios.

Prerequisites

First, ensure you have Docker installed on your Mac, Windows, or Linux machine.

Running the Container

Once Docker is ready, open your terminal and execute the following command. Remember to replace <YOUR_TIMEZONE> with your actual timezone (e.g., America/New_York or Europe/Berlin).

docker run -it --rm \
  --name n8n \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  -e GENERIC_TIMEZONE="<YOUR_TIMEZONE>" \
  -e TZ="<YOUR_TIMEZONE>" \
  docker.n8n.io/n8nio/n8n

Let's break down this command:

• docker run -it --rm: Runs the container in interactive mode (-it) and automatically removes it on stop (--rm), perfect for testing.
• --name n8n: Assigns a memorable name to your container.
• -p 5678:5678: Maps port 5678 from your local machine to the container, allowing you to access the n8n UI.
• -v n8n_data:/home/node/.n8n: This is crucial for data persistence. It creates a Docker volume named n8n_data to store your workflows, credentials, and execution data. Without it, you would lose all your work on restart.
• -e ...: Sets environment variables for configuring the timezone.

Once the container starts, access your n8n instance at http://localhost:5678.

Method 2: A Robust Setup with Docker Compose

While docker run is great for a quick start, a production-ready setup needs a persistent database like PostgreSQL instead of the default SQLite. Managing multiple related containers (like n8n and its database) is where Docker Compose excels. It allows you to define a multi-service application in a single docker-compose.yml file, simplifying management.

Prerequisites

• Docker
• Docker Compose (included with Docker Desktop)

Creating the Docker Compose File

1. Create a new directory for your project (e.g., my-n8n-stack).
2. Inside it, create a file named docker-compose.yml.
3. Paste in the following configuration:

version: '3.8'
 
services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "127.0.0.1:5678:5678"
    environment:
      - QUEUE_HEALTH_CHECK_ACTIVE=true
      - N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true
      - N8N_RUNNERS_ENABLED=true
      - DB_TYPE=postgresdb
      - DB_POSTGRESDB_HOST=postgres
      - DB_POSTGRESDB_PORT=5432
      - DB_POSTGRESDB_DATABASE=${POSTGRES_DB}
      - DB_POSTGRESDB_USER=${POSTGRES_USER}
      - DB_POSTGRESDB_PASSWORD=${POSTGRES_PASSWORD}
      - GENERIC_TIMEZONE=America/New_York # Change this
      - TZ=America/New_York               # Change this
    volumes:
      - n8n_data:/home/node/.n8n
    depends_on:
      - postgres
 
  postgres:
    image: postgres:15
    restart: always
    environment:
      - POSTGRES_DB=${POSTGRES_DB}
      - POSTGRES_USER=${POSTGRES_USER}
      - POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
    volumes:
      - postgres_data:/var/lib/postgresql/data
 
volumes:
  n8n_data:
  postgres_data:

4. Next, create a .env file in the same directory to store your credentials. Never hardcode secrets in your docker-compose.yml file.

# .env file
POSTGRES_DB=n8n
POSTGRES_USER=n8nuser
POSTGRES_PASSWORD=a-very-secure-password

Running the Stack

With both files in place, open your terminal in the project directory and run:

docker compose up -d

This command downloads the required images, creates the volumes, and starts both services in the background (-d). Your n8n instance, now backed by a robust PostgreSQL database, is available at http://localhost:5678.

Beyond the Setup: The Operational Realities of Docker

Setting up n8n with Docker is clearly achievable. However, the real challenges emerge when you move from a local playground to a production environment:

• Configuration Sprawl: A production-grade docker-compose file can become a monster, tangled with reverse proxies for SSL, complex networking rules, and dozens of environment variables.
• Accidental DBA Duty: You are now a database administrator. You're responsible for updating PostgreSQL, managing backups, and securing its data.
• Fragile Updates: Updating n8n means manually pulling the new Docker image, stopping the containers, and restarting them, hoping nothing breaks in the process.
• No Clear Path to Scale: If your automation load grows, how do you scale? How do you ensure high availability and automatic recovery from a crash? Docker Compose offers no native answers.
• A Fragmented World: You have to manage domains, SSL certificates, firewalls, and monitoring separately. Your n8n instance is just one piece of a large, disjointed puzzle.

This operational burden is a constant distraction from the real goal: building powerful automations.

The Simpler Alternative: One-Click n8n on Sealos

What if you could gain the control of self-hosting without paying the complexity tax? What if you could deploy n8n to enterprise-grade infrastructure without touching a line of YAML or a Docker command? This is where Sealos comes in.

Deploy n8n on Sealos in Under a Minute

The fastest way to get started is by using the Deploy on Sealos button, which takes you directly to a pre-configured n8n template.

1. After clicking the button above, select "Deploy Now".
   • If you're new to Sealos, you'll be prompted to create a free account and log in. You will then be redirected back to the template.
2. Configure Your Project. On the deployment page, you can customize your n8n instance. Key options include:
   • Use PostgreSQL: Check the box for "Use PostgreSQL database for production workloads." This is highly recommended for better performance and data persistence.
   • Enable Queue Mode: For advanced use cases, you can select "Enable queue mode with Redis and workers for improved scalability and parallel execution." Note that this option requires PostgreSQL to be enabled.
3. Click "Deploy App" to start the deployment.
4. Once the process is complete, click on the application's "Details" to find the public URL. Your n8n instance is now live.

That's it. In under a minute, Sealos provisions and deploys a production-ready n8n instance with a public URL and a valid SSL certificate. No command line, no YAML, no complexity.

Sealos also supports custom domains. After deployment, you can update the application to add your domain and then adjust the WEBHOOK_URL environment variable to match.
