ติดตั้ง n8n in docker with https ngrok

Introduction

This tutorial will guide you through the process of installing n8n in Docker and configuring it to run with HTTPS using ngrok. This setup allows you to use webhooks securely, providing a static domain for your n8n instance.

Step 1: Install Docker

Before you can use n8n and ngrok, ensure you have Docker installed on your machine. If you haven't installed Docker yet, follow these steps:

1. Go to the Docker website.
2. Download the installer for your operating system (Windows, macOS, or Linux).
3. Follow the installation instructions provided.

Step 2: Set Up ngrok in Docker

To run ngrok in Docker, you'll need to execute a command in your terminal. Follow these steps:

1. Open your terminal.

2. Run the following command, replacing AUTH-TOKEN and DOMAIN-FROM-NGROK with your ngrok auth token and desired domain:

   docker run -d \
   --name ngrok-https \
   -e NGROK_AUTHTOKEN=AUTH-TOKEN \
   ngrok/ngrok:latest \
   http --domain=DOMAIN-FROM-NGROK host.docker.internal:5678
   

   • Change ngrok-https to a name of your choice for the ngrok container.
   • The NGROK_AUTHTOKEN value is obtained from your ngrok account.
   • The DOMAIN-FROM-NGROK should be the static domain you receive from ngrok.

Step 3: Configure Environment Variables for n8n

Next, you need to set up the necessary environment variables for n8n. These variables ensure that n8n operates correctly with ngrok.

1. Create a .env file for your n8n setup if you haven't already.

2. Add the following lines to your .env file, replacing NGROK-DOMAIN with your ngrok static domain:

   N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true
   N8N_EDITOR_BASE_URL=https://NGROK-DOMAIN
   WEBHOOK_URL=https://NGROK-DOMAIN
   N8N_DEFAULT_BINARY_DATA_MODE=filesystem
   N8N_RUNNERS_ENABLED=true
   N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true
   

Step 4: Run n8n in Docker

Now, you can run n8n itself using Docker:

1. Use the following command to start n8n:

   docker run -d \
   --name n8n \
   -p 5678:5678 \
   --env-file .env \
   n8n
   

   • This command will run n8n on port 5678.

Step 5: Access n8n

After running the containers, you can access your n8n instance:

1. Open your web browser.
2. Navigate to https://NGROK-DOMAIN, where NGROK-DOMAIN is the domain you set up with ngrok.

Conclusion

You have successfully set up n8n in Docker with HTTPS using ngrok. This configuration allows you to securely use webhooks with a static domain.

Next Steps

• Explore n8n's features and capabilities to automate workflows.
• Review ngrok documentation for advanced configurations and troubleshooting.
• Consider using a custom domain for production use instead of the ngrok domain for better branding and reliability.
