Order now | Download | FAQ | n8n
Overview
The Docker NextCloud WHMCS module leverages a sophisticated workflow for n8n, designed to automate the comprehensive deployment, configuration, and management processes for NextCloud and NextCloud Office services. Through its intuitive API interface, the workflow securely receives commands and orchestrates predefined tasks via SSH on your Docker-hosted server, ensuring streamlined operations and efficient management.
Prerequisites

You must deploy your own dedicated n8n server to manage workflows effectively.
Alternatively, you may opt for the official n8n cloud-based solutions accessible via: n8n Official Site

Your Docker server must be accessible via SSH with necessary permissions.

Installation Steps

Import this workflow file directly into your n8n server manually.

n8n Workflow API Backend Setup for WHMCS
Configure API Webhook and SSH Access

Create a secure Basic Auth Credential for Webhook API interactions within n8n. [

Create an SSH Credential within n8n to securely communicate with the Docker host. 

Modify Template Parameters
Adjust and update the following critical parameters to match your deployment specifics:

server_domain – Set this to the domain of your WHMCS Docker server.

clients_dir – Specify the directory where user data and related resources will be stored.

mount_dir – The standard mount point for container storage (recommended to remain unchanged).

Do not alter the following technical parameters to avoid workflow disruption: screen_left, screen_right.
Deploy-docker-compose Configuration
Fine-tune Docker Compose configurations tailored specifically for these critical operational scenarios:

Initial service provisioning and setup
Service suspension and subsequent unlocking
Service configuration updates
Routine service maintenance tasks

nginx Configuration Management
Enhance and customize proxy server configurations using the dedicated nginx workflow element:

main: Define specialized parameters within the server configuration block.

main_location: Set custom headers, caching policies, and routing rules for the root location.

Bash Script Automation
Automate Docker container management and related server tasks through dynamically generated Bash scripts within n8n. Scripts execute securely via SSH and provide responses in JSON or plain text formats for easy parsing and logging.

Scripts are conveniently linked directly to the SSH action elements.
You retain complete flexibility to adapt or extend these scripts as necessary to meet your precise operational requirements.
