Demo

This :tv: short video (< 4 min) goes over key concepts of creating workflows in n8n.

Available integrations

n8n has 200+ different nodes to automate workflows. A full list can be found at [***]

Documentation

The official n8n documentation can be found at [***]

Additional information and example workflows are available on the website at [***]

Start n8n in Docker

In the terminal, enter the following:

bash
docker volume create n8n_data

docker run -it --rm \
 --name n8n \
 -p 5678:5678 \
 -v n8n_data:/home/node/.n8n \
 docker.n8n.io/n8nio/n8n

This command will download the required n8n image and start your container. You can then access n8n by opening: http://localhost:5678

To save your work between container restarts, it also mounts a docker volume, n8n_data. The workflow data gets saved in an SQLite database in the user folder (/home/node/.n8n). This folder also contains important data like the webhook URL and the encryption key used for securing credentials.

If this data can't be found at startup n8n automatically creates a new key and any existing credentials can no longer be decrypted.

Start n8n with tunnel

WARNING: This is only meant for local development and testing and should NOT be used in production!

n8n must be reachable from the internet to make use of webhooks - essential for triggering workflows from external web-based services such as GitHub. To make this easier, n8n has a special tunnel service which redirects requests from our servers to your local n8n instance. You can inspect the code running this service here: [***]

To use it simply start n8n with --tunnel

bash
docker volume create n8n_data

docker run -it --rm \
 --name n8n \
 -p 5678:5678 \
 -v n8n_data:/home/node/.n8n \
 docker.n8n.io/n8nio/n8n \
 start --tunnel

Use with PostgreSQL

By default, n8n uses SQLite to save credentials, past executions and workflows. However, n8n also supports using PostgreSQL.

WARNING: Even when using a different database, it is still important to persist the /home/node/.n8n folder, which also contains essential n8n user data including the encryption key for the credentials.

In the following commands, replace the placeholders (depicted within angled brackets, e.g. <POSTGRES_USER>) with the actual data:

bash
docker volume create n8n_data

docker run -it --rm \
 --name n8n \
 -p 5678:5678 \
 -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

A full working setup with docker-compose can be found here.

Passing sensitive data using files

To avoid passing sensitive information via environment variables, "_FILE" may be appended to some environment variable names. n8n will then load the data from a file with the given name. This makes it possible to load data easily from Docker and Kubernetes secrets.

The following environment variables support file input:

• DB_POSTGRESDB_DATABASE_FILE
• DB_POSTGRESDB_HOST_FILE
• DB_POSTGRESDB_PASSWORD_FILE
• DB_POSTGRESDB_PORT_FILE
• DB_POSTGRESDB_USER_FILE
• DB_POSTGRESDB_SCHEMA_FILE

Example server setups

Example server setups for a range of cloud providers and scenarios can be found in the Server Setup documentation.

Updating

Before you upgrade to the latest version make sure to check here if there are any breaking changes which may affect you: Breaking Changes

From your 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

bash
docker pull docker.n8n.io/n8nio/n8n

Pull specific version

bash
docker pull docker.n8n.io/n8nio/n8n:0.220.1

Pull next (unstable) version

bash
docker pull docker.n8n.io/n8nio/n8n:next

Stop the container and start it again:

1. Get the container ID:

bash
docker ps -a

2. Stop the container with ID container_id:

bash
docker stop [container_id]

3. Remove the container (this does not remove your user data) with ID container_id:

bash
docker rm [container_id]

4. Start the new container:

bash
docker run --name=[container_name] [options] -d docker.n8n.io/n8nio/n8n

Updating with Docker Compose

If you run n8n using a Docker Compose file, follow these steps to update n8n:

bash
# Pull latest version
docker compose pull

# Stop and remove older version
docker compose down

# Start the container
docker compose up -d

Setting the timezone

To specify the timezone n8n should use, the environment variable GENERIC_TIMEZONE can be set. One example where this variable has an effect is the Schedule node.

The system's timezone can be set separately with the environment variable TZ. This controls the output of certain scripts and commands such as $ date.

For example, to use the same timezone for both:

bash
docker run -it --rm \
 --name n8n \
 -p 5678:5678 \
 -e GENERIC_TIMEZONE="Europe/Berlin" \
 -e TZ="Europe/Berlin" \
 docker.n8n.io/n8nio/n8n

For more information on configuration and environment variables, please see the n8n documentation.

Build Docker-Image

bash
docker buildx build --platform linux/amd64,linux/arm64 --build-arg N8N_VERSION=<VERSION> -t n8n:<VERSION> .

# For example:
docker buildx build --platform linux/amd64,linux/arm64 --build-arg N8N_VERSION=1.30.1 -t n8n:1.30.1 .

What does n8n mean and how do you pronounce it?

Short answer: It means "nodemation" and it is pronounced as n-eight-n.

Long answer: I get that question quite often (more often than I expected) so I decided it is probably best to answer it here. While looking for a good name for the project with a free domain I realized very quickly that all the good ones I could think of were already taken. So, in the end, I chose nodemation. "node-" in the sense that it uses a Node-View and that it uses Node.js and "-mation" for "automation" which is what the project is supposed to help with. However, I did not like how long the name was and I could not imagine writing something that long every time in the CLI. That is when I then ended up on "n8n". Sure it does not work perfectly but neither does it for Kubernetes (k8s) and I did not hear anybody complain there. So I guess it should be ok.
