   version: "3.8"
   services:
     shuffler:
       image: ghcr.io/frikky/shuffler:latest
       ports:
         - "8000:8000"
       volumes:
         - shuffler_data:/data

5. Access Shuffler: Open your web browser and navigate to `http://localhost:8000`.

Usage

Once Shuffler is installed, the real fun begins: creating and executing workflows. Let’s walk through a simple example: automating the process of sending an email when a new file is added to a specific directory.

1. Log in to Shuffler: Use the default credentials (usually found in the documentation or initial setup instructions) to log in to the Shuffler web interface.
2. Create a New Workflow: Click on the “Create Workflow” button to start a new workflow. Give it a descriptive name, such as “File Upload Notification.”
3. Add a Trigger: Triggers initiate the workflow based on specific events. In this case, we’ll use a “File System Watcher” trigger. Search for the “File System Watcher” app in the app library and drag it onto the workflow canvas.
4. Configure the Trigger: Configure the trigger to monitor the desired directory. Specify the path to the directory and set the event type to “File Created.”

{
  "directory": "/path/to/your/directory",
  "event_type": "FileCreated"
}
    

5. Add an Action: Actions perform specific tasks within the workflow. In this case, we’ll use the “Email” app to send an email notification. Search for the “Email” app and drag it onto the canvas.
6. Connect the Trigger and Action: Connect the output of the “File System Watcher” trigger to the input of the “Email” action. This establishes the flow of data from the trigger to the action.
7. Configure the Action: Configure the “Email” action with the recipient’s email address, subject, and body. You can use variables from the trigger’s output, such as the file name, in the email body.

   
   {
     "to": "recipient@example.com",
     "subject": "New File Uploaded",
     "body": "A new file named {{filename}} has been uploaded to the directory."
   }
       

8. Save and Activate the Workflow: Save the workflow and activate it to start monitoring the directory.

Now, whenever a new file is added to the specified directory, Shuffler will automatically send an email notification to the recipient.
