✅ Implementation Complete: Unified Installation Script

Problem Statement

Let setup script have the option of Kubernetes, Docker or Standalone for installation of the full list of services on ubuntu lts or alma/redhat linux

Solution Delivered

A comprehensive unified installation script (install.sh) that provides an interactive wizard allowing users to choose between three installation methods:

  1. Kubernetes - Production-ready container orchestration
  2. Docker Compose - Development and small-scale deployments
  3. Standalone - Traditional server installation

Supported Operating Systems

✅ Ubuntu LTS: 20.04, 22.04, 24.04 ✅ Debian: 11 (Bullseye), 12 (Bookworm) ✅ AlmaLinux: 8, 9, 10 ✅ Red Hat Enterprise Linux (RHEL): 8, 9, 10 ✅ Rocky Linux: 8, 9, 10 ✅ CloudLinux: 8, 9, 10 (Standalone only)

What Was Implemented

1. Core Installation Script (install.sh - 925 lines)

Features:

  • Interactive installation wizard with color-coded UI
  • Automatic OS detection and validation
  • Three installation methods (Kubernetes, Docker, Standalone)
  • Integration with existing installation scripts
  • Secure password generation
  • SSL certificate automation
  • Comprehensive error handling
  • Post-installation guidance

Functions:

  • display_banner() - Professional ASCII art welcome screen
  • detect_os() - OS detection with version validation
  • install_kubernetes() - K8s installation workflow
  • install_docker() - Docker Compose setup
  • install_standalone() - Native service installation
  • Plus 25+ helper functions

2. Comprehensive Documentation (1,246 lines total)

Installation Guide (docs/INSTALLATION_GUIDE.md - 466 lines)

  • Complete installation instructions
  • Method comparison tables
  • OS-specific requirements
  • Troubleshooting section
  • Security best practices
  • Post-installation tasks

Script README (INSTALL_SCRIPT_README.md - 326 lines)

  • Advanced usage examples
  • Environment variable reference
  • Resource requirements
  • Integration details
  • Support information

Implementation Summary (UNIFIED_INSTALLER_IMPLEMENTATION.md - 454 lines)

  • Technical architecture
  • Feature breakdown
  • Testing details
  • Integration information

3. Automated Testing (test-install-script.sh - 149 lines)

10 Comprehensive Tests:

  1. ✅ Script exists and is executable
  2. ✅ Bash syntax is valid
  3. ✅ Required functions exist
  4. ✅ OS detection logic exists
  5. ✅ Installation method options exist
  6. ✅ Supporting scripts exist
  7. ✅ Documentation exists
  8. ✅ Docker compose configuration exists
  9. ✅ README contains installation info
  10. ✅ Proper shebang and error handling

Result: All tests PASS ✅

4. Updated Documentation

  • README.md - Added prominent "Unified Installation" section
  • Links to comprehensive installation guide
  • Quick start examples

Services Installed (All Methods)

Each installation method deploys the complete stack:

✅ Control Panel (Laravel + Filament) ✅ NGINX Web Server ✅ Database (MariaDB or PostgreSQL) ✅ Redis Cache ✅ Mail Services (Postfix + Dovecot) ✅ DNS Server (BIND9 or PowerDNS) ✅ SSL Certificates (Let's Encrypt) ✅ PHP Multi-version Support (8.1-8.5)

How to Use

Basic Installation (Interactive)

git clone https://github.com/liberu-control-panel/control-panel-laravel.git
cd control-panel-laravel
sudo ./install.sh

Automated Installation

Kubernetes:

export INSTALLATION_METHOD=kubernetes
sudo -E ./install.sh

Docker:

export INSTALLATION_METHOD=docker
export DOMAIN=control.example.com
export EMAIL=admin@example.com
sudo -E ./install.sh

Standalone:

export INSTALLATION_METHOD=standalone
export DOMAIN=control.example.com
export EMAIL=admin@example.com
sudo -E ./install.sh

Architecture Highlights

Kubernetes Installation

  • Integrates with existing install-k8s.sh script
  • Auto-detects managed Kubernetes (EKS, AKS, GKE, DOKS)
  • Deploys via install-control-panel.sh
  • Includes Helm chart deployment
  • Supports S3 storage for persistence

Docker Compose Installation

  • Installs Docker Engine and Compose
  • Generates secure secrets automatically
  • Creates .env from template
  • Supports both MariaDB and PostgreSQL
  • Automatic Let's Encrypt SSL

Standalone Installation

Ubuntu:

  • Adds Ondřej Surý's PHP PPA
  • Installs PHP 8.3 + extensions
  • Configures NGINX + PHP-FPM
  • Sets up MariaDB, Redis
  • Installs Certbot for SSL

RHEL/AlmaLinux:

  • Enables EPEL repository
  • Adds Remi's PHP repository
  • Configures SELinux
  • Uses dnf package manager
  • Handles different service paths

Security Features

✅ Auto-generated secure passwords ✅ SSL certificate automation ✅ Proper file permissions ✅ SELinux configuration (RHEL/AlmaLinux) ✅ Docker secrets for sensitive data ✅ Root access verification
