วิธีติดตั้ง n8n และ Docker [สำหรับใช้งานจริง]

Introduction

This tutorial provides a step-by-step guide on how to install n8n using Docker. n8n is an open-source workflow automation tool that allows you to connect various services and create complex workflows. By using Docker, you can easily deploy n8n in a containerized environment. This guide is designed for practical use and will help you set up n8n for real-world applications.

Step 1: Install Docker and Docker Compose

Before you can run n8n, you need to have Docker and Docker Compose installed on your machine.

1. Install Docker

   • Visit the Docker installation page and follow the instructions specific to your operating system (Windows, macOS, Linux).

2. Install Docker Compose

   • Docker Compose comes with Docker Desktop on Windows and macOS. For Linux, follow the Docker Compose installation instructions.

Step 2: Create a Docker Compose File

Now, you need to create a Docker Compose file that defines the n8n service and its configuration.

1. Open your terminal or command prompt.

2. Create a new directory for your project:

   mkdir n8n-docker
   cd n8n-docker
   

3. Create a file named docker-compose.yml:

   touch docker-compose.yml
   

4. Open the file in a text editor and add the following configuration:

   version: '3.8'
   services:
     n8n:
       image: docker.n8n.io/n8nio/n8n
       container_name: n8n
       restart: always
       ports:
         - "5678:5678"
       volumes:
         - n8n_data:/home/node/.n8n
       environment:
         - N8N_BASIC_AUTH_ACTIVE=true
         - N8N_BASIC_AUTH_USER=admin
         - N8N_BASIC_AUTH_PASSWORD=your_password
         - TZ=Asia/Bangkok
   volumes:
     n8n_data:
   

   • Replace your_password with a strong password of your choice.

Step 3: Start n8n with Docker Compose

With your docker-compose.yml file configured, you're ready to start n8n.

1. In your terminal, run the following command:

   docker-compose up -d
   

   • This command starts the n8n service in detached mode.

2. Check if n8n is running:

   • You can verify that n8n is running by checking the logs:

   docker-compose logs -f
   

Step 4: Access the n8n Interface

After starting n8n, you can access its web interface.

1. Open your web browser and go to:

   http://localhost:5678
   

2. Log in using the credentials you set in the docker-compose.yml file:

   • Username: admin
   • Password: your_password

Conclusion

You have successfully installed n8n using Docker and can now start building workflows. Remember to keep your Docker containers updated and manage your volumes for data persistence. As a next step, explore n8n’s features and consider integrating it with other services to automate your tasks effectively.
