How to Self-Host n8n with Docker: The Complete 2026 Guide
If you’re planning to automate workflows efficiently in 2026, one of the best decisions you can make is to Self-Host n8n with Docker. n8n has become a go-to automation and workflow orchestration platform for developers, SaaS owners, agencies, and tech teams. And thanks to Docker, running it on your own server is now easier, faster, and more secure than ever.
This in-depth 2026 guide will walk you through everything: installing Docker, running n8n, configuring environment variables, securing your setup, enabling backups, scaling, connecting databases, and long-term maintenance best practices. Whether you’re hosting on a VPS, cloud provider, or bare-metal server, this guide will help you launch a stable, production-ready n8n instance.
Why Self-Host n8n in 2026?
While n8n.cloud is great for quick setups, self-hosting offers major advantages:
- Full data control & privacy
- Unlimited workflows
- Scalable infrastructure
- Lower long-term operational cost
- Ability to customize and integrate deeply
- Freedom to use your own database and storage
And best of all — Docker makes everything portable, consistent, and easy to manage.
- Prerequisites Before You Self-Host n8n with Docker
Before deploying, make sure your system is ready:
✔ Server Requirements
- Minimum 2 GB RAM
- At least 1 CPU
- 10 GB storage (more recommended for execution logs)
✔ Install Required Packages
- Make sure your OS is updated:
sudo apt update && sudo apt upgrade -y
- Install Docker:
curl -fsSL https://get.docker.com | sudo sh
- Install Docker Compose:
sudo apt install docker-compose -y
- After installation:
docker –version
docker-compose –version
If both commands return versions, you’re good to go.
- Creating Your n8n Docker Project
- Create a directory:
mkdir n8n-docker
cd n8n-docker
Now create your docker-compose.yml file.
- The Best 2026 docker-compose.yml for n8n
- Here is the most stable and updated configuration for production in 2026:
version: ‘3.8’
services:
n8n:
image: n8nio/n8n:latest
restart: always
ports:
- “5678:5678”
environment:
- N8N_HOST=your-domain.com
- N8N_PORT=5678
- N8N_PROTOCOL=https
- GENERIC_TIMEZONE=Asia/Kolkata
- DB_TYPE=postgresdb
- DB_POSTGRESDB_HOST=postgres
- DB_POSTGRESDB_PORT=5432
- DB_POSTGRESDB_USER=n8n
- DB_POSTGRESDB_PASSWORD=password123
- DB_POSTGRESDB_DATABASE=n8n
- NODE_ENV=production
volumes:
- n8n_data:/home/node/.n8n
postgres:
image: postgres:15
restart: always
environment:
- POSTGRES_USER=n8n
- POSTGRES_PASSWORD=password123
- POSTGRES_DB=n8n
volumes:
- postgres_data:/var/lib/postgresql/data
volumes:
n8n_data:
postgres_data:
- Start n8n with Docker
- Run this command inside your directory:
docker-compose up -d
- Now open your browser:
Congratulations! You officially Self-Host n8n with Docker successfully.
- Configuring Important n8n Environment Variables (2026 Best Practices)
To make your setup scalable and production-safe, the following variables are recommended:
- Security
N8N_BASIC_AUTH_ACTIVE=true
N8N_BASIC_AUTH_USER=admin
N8N_BASIC_AUTH_PASSWORD=yourStrongPassword
- Workflow Execution History
EXECUTIONS_DATA_SAVE_ON_SUCCESS=none
EXECUTIONS_DATA_SAVE_ON_ERROR=all
- Webhook URL Settings
WEBHOOK_URL=https://your-domain.com/
- Setting Up SSL (HTTPS) for n8n
Use Nginx Proxy Manager or Caddy for automatic SSL.
✔ Option 1: Caddy (Best for 2026)
Create Caddyfile:
reverse_proxy localhost:5678
}
Caddy fetches SSL certificates automatically.
- Connecting n8n to External Storage (Optional)
- Amazon S3 / Minio (recommended for large automation setups)
EXECUTIONS_MODE=queue
EXECUTIONS_DATA_PRUNE=true
- Setting Up Backups for n8n
Use Docker volumes for persistent storage:
- Backup n8n:
docker run –rm -v n8n_data:/data -v $(pwd):/backup alpine tar czvf /backup/n8n_backup.tar.gz /data
Backup PostgreSQL:
docker exec -t postgres pg_dumpall -c -U n8n > postgres_backup.sql
- Scaling n8n in 2026
For large workflows:
- Enable queue mode:
EXECUTIONS_MODE=queue
- Deploy Redis:
redis:
image: redis:7
Then add worker containers to scale horizontally.
- Keeping Your n8n Updated in 2026
Update n8n safely:
docker-compose pull
docker-compose down
docker-compose up -d
Updates usually take 30 seconds.
- Common Issues & Fixes
- n8n not starting
- Check logs:
docker logs n8n
Database connection issues
Ensure PostgreSQL container is running:
docker ps
SSL problems
- Confirm DNS is pointing correctly
- Restart proxy service
- Best Practices for Self-Hosting n8n in 2026
- Always run n8n behind a reverse proxy
- Use PostgreSQL (never SQLite for production)
- Enable basic auth
- Use strong passwords
- Set up regular backups
- Keep server updated
- Run n8n in queue mode for heavy workflows
- Use domain instead of IP
