Docker Installation

n8n recommends using Docker for most self-hosting needs. It provides a clean, isolated environment, avoids operating system and tooling incompatibilities, and makes database and environment management simpler.

You can also use n8n in Docker with Docker Compose. You can find Docker Compose configurations for various architectures in the n8n-hosting repository.

You can also follow along with our video guide here:

Prerequisites

Before proceeding, install Docker:

• Docker Desktop is available for Mac, Windows, and Linux. Docker Desktop includes the Docker Engine and Docker Compose.
• Docker Engine and Docker Compose are also available as separate packages for Linux. Use this for Linux machines without a graphical environment or when you don't want the Docker Desktop UI.

Starting n8n

From your terminal, run the following commands, replacing the <YOUR_TIMEZONE> placeholders with your timezone:

docker volume create n8n_data

docker run -it --rm \
 --name n8n \
 -p 5678:5678 \
 -e GENERIC_TIMEZONE="<YOUR_TIMEZONE>" \
 -e TZ="<YOUR_TIMEZONE>" \
 -e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true \
 -e N8N_RUNNERS_ENABLED=true \
 -v n8n_data:/home/node/.n8n \
 docker.n8n.io/n8nio/n8n

This command creates a volume to store persistent data, downloads the required n8n image, and starts the container with the following settings:

• Maps and exposes port 5678 on the host.
• Sets the timezone for the container:
  • the TZ environment variable sets the system timezone to control what scripts and commands like date return.
  • the GENERIC_TIMEZONE environment variable sets the correct timezone for schedule-oriented nodes like the Schedule Trigger node.
• Enforces secure file permissions for the n8n configuration file.
• Enables task runners, the recommended way of executing tasks in n8n.
• Mounts the n8n_data volume to the /home/node/.n8n directory to persist your data across container restarts.

Once running, you can access n8n by opening: http://localhost:5678

Using with PostgreSQL

By default, n8n uses SQLite to save credentials, past executions, and workflows. n8n also supports PostgreSQL, configurable using environment variables as detailed below.

/// note | Persisting the .n8n directory still recommended When using PostgreSQL, n8n doesn't need to use the .n8n directory for the SQLite database file. However, the directory still contains other important data like encryption keys, instance logs, and source control feature assets. While you can work around some of these requirements, (for example, by setting the N8N_ENCRYPTION_KEY environment variable), it's best to continue mapping a persistent volume for the directory to avoid potential issues. ///

To use n8n with PostgreSQL, execute the following commands, replacing the placeholders (depicted within angled brackets, for example <POSTGRES_USER>) with your actual values:

docker volume create n8n_data

docker run -it --rm \
 --name n8n \
 -p 5678:5678 \
 -e GENERIC_TIMEZONE="<YOUR_TIMEZONE>" \
 -e TZ="<YOUR_TIMEZONE>" \
 -e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true \
 -e N8N_RUNNERS_ENABLED=true \
 -e DB_TYPE=postgresdb \
 -e DB_POSTGRESDB_DATABASE=<POSTGRES_DATABASE> \
 -e DB_POSTGRESDB_HOST=<POSTGRES_HOST> \
 -e DB_POSTGRESDB_PORT=<POSTGRES_PORT> \
 -e DB_POSTGRESDB_USER=<POSTGRES_USER> \
 -e DB_POSTGRESDB_SCHEMA=<POSTGRES_SCHEMA> \
 -e DB_POSTGRESDB_PASSWORD=<POSTGRES_PASSWORD> \
 -v n8n_data:/home/node/.n8n \
 docker.n8n.io/n8nio/n8n

You can find a complete docker-compose file for PostgreSQL in the n8n hosting repository.

Updating

To update n8n, in Docker Desktop, navigate to the Images tab and select Pull from the context menu to download the latest n8n image:

You can also use the command line to pull the latest, or a specific version:

# Pull latest (stable) version
docker pull docker.n8n.io/n8nio/n8n

# Pull specific version
docker pull docker.n8n.io/n8nio/n8n:1.81.0

# Pull next (unstable) version
docker pull docker.n8n.io/n8nio/n8n:next

After pulling the updated image, stop your n8n container and start it again. You can also use the command line. Replace <container_id> in the commands below with the container ID you find in the first command:

# Find your container ID
docker ps -a

# Stop the container with the `<container_id>`
docker stop <container_id>

# Remove the container with the `<container_id>`
docker rm <container_id>

# Start the container
docker run --name=<container_name> [options] -d docker.n8n.io/n8nio/n8n

Updating Docker Compose

--8<-- "_snippets/self-hosting/installation/docker-compose-updating.md"

--8<-- "_snippets/self-hosting/installation/tunnel.md"

Start n8n with --tunnel by running:

docker volume create n8n_data

docker run -it --rm \
 --name n8n \
 -p 5678:5678 \
 -e GENERIC_TIMEZONE="<YOUR_TIMEZONE>" \
 -e TZ="<YOUR_TIMEZONE>" \
 -e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true \
 -e N8N_RUNNERS_ENABLED=true \
 -v n8n_data:/home/node/.n8n \
 docker.n8n.io/n8nio/n8n \
 start --tunnel
