Key Features and Highlights

This workflow offers a comprehensive API backend solution for managing and controlling Docker-based n8n container instances via the n8n automation platform, specifically tailored for integration with WHMCS/WISECP modules. It supports a wide range of operations including container deployment, start, stop, disk mounting, permission management, network statistics, log viewing, user management, and password modification. All commands are executed remotely over SSH to ensure efficiency and security.

Highlights include:

  • Receiving commands via Webhook API, supporting various container and service operation instructions.
  • Automatic generation and management of docker-compose and Nginx configuration files for flexible container deployment and access control.
  • Support for creating, mounting, and unmounting disk image files to enable data persistence and isolation.
  • Real-time querying of container status, performance metrics, logs, and user information.
  • Built-in error handling mechanisms to ensure accurate and timely operation feedback.
  • Seamless integration with WHMCS/WISECP for streamlined hosting service automation.

Core Problems Addressed

  • Automating the lifecycle management of n8n instances within Docker containers to eliminate manual complexity and reduce errors.
  • Providing a reliable backend API interface for WHMCS/WISECP modules to simplify service provider operations.
  • Enabling dynamic mounting and unmounting of container disks to ensure data security and optimal resource utilization.
  • Offering fine-grained access control (ACL) management to enhance system security.
  • Implementing container resource monitoring and log collection to facilitate troubleshooting and performance optimization.

Application Scenarios

  • Cloud service providers managing containerized n8n services via WHMCS/WISECP for automated deployment and maintenance.
  • IT operations teams automating Docker container management to quickly respond to business demands.
  • Containerized workflow platforms requiring dynamic storage mounting and flexible resource configuration.
  • Enterprises needing API-based integration for container lifecycle and user permission management.

Main Workflow Steps

  1. Receive API Request: Accept POST requests with operation commands via a Webhook node, performing authentication.
  2. Initialize Parameters: Set basic parameters such as server domain and directory paths.
  3. Domain Validation: Verify the validity of the request domain; reject invalid requests with an error response.
  4. Command Routing: Use a Switch node to route requests based on command parameters to corresponding operation flows (container operations, service commands, status queries, etc.).
  5. SSH Remote Execution: Execute corresponding bash script commands on the target server via SSH node to perform container start, stop, deployment, disk mounting, permission adjustments, log queries, and more.
  6. Result Processing: Parse command output and generate standardized JSON responses for the caller.
  7. Security Management: Control access permissions via Nginx and ACL configuration files, supporting dynamic updates and reloads.
