This automated n8n workflow delivers an instant DevOps toolkit by installing Docker, K3s, Jenkins, Grafana, and more on a Linux server within 10 seconds. It optimizes performance, enhances security, and provides ready-to-use templates for DevOps projects.

Main Components

  • Configure Parameters - Defines server details, tool versions, and credentials
  • System Preparation - Updates the system and installs base packages
  • Install Docker - Deploys Docker Engine and Docker Compose
  • Install Kubernetes - Sets up K3s cluster with kubectl, Helm, and k9s
  • Install Jenkins - Configures Jenkins CI/CD server with Docker integration
  • Install Monitoring - Deploys Prometheus and Grafana using Helm charts
  • Create DevOps User - Establishes a dedicated user with appropriate permissions
  • Security Configuration - Implements firewall, VS Code, and Terraform
  • Final Configuration - Sets up sample projects and configuration files
  • Setup Complete - Provides a summary and access details

Essential Prerequisites

  • Linux server with SSH access
  • Root-level administrative privileges

Customization Guide

  • Adjust tool versions or credentials in the Configure Parameters node
  • Modify the number of nodes or security settings as needed

Features

  • 🔧 Core DevOps Tools Installed:
    • Docker - Container platform with Docker Compose
    • Kubernetes - K3s (lightweight) with kubectl and Helm
    • Jenkins - CI/CD automation server
    • Prometheus - Monitoring and alerting
    • Grafana - Visualization and dashboards
  • Optimizations Made:
    • Streamlined Commands - Combined multiple operations into single bash scripts
    • Reduced Nodes - 10 nodes vs 12 in original (more efficient)
    • Better Error Handling - Each step includes verification
    • Cloud-Ready - Includes AWS CLI, Azure CLI, and Google Cloud SDK
    • Security First - Proper firewall configuration and user permissions

Parameters to Configure

  • server_host: Your Linux server IP address
  • server_user: SSH username (typically 'root')
  • server_password: SSH password
  • docker_version: Docker version to install
  • k3s_version: K3s version to install
  • username: DevOps username
  • user_password: Password for the DevOps user

How to Use

  • Copy the JSON code from the artifact
  • Open your n8n workspace
  • Select "Import from JSON" or "+" → "From JSON"
  • Paste the JSON code
  • Configure parameters in the "Configure Parameters" node with your server details
  • Run the workflow

Workflow Actions

  • Install: Deploys Docker, K3s, Jenkins, Prometheus, and Grafana with optimizations
  • Create User: Sets up a DevOps user with necessary permissions
  • Configure: Applies security settings and provides templates
