go-config-manager

A robust, generic configuration manager for Go applications using Viper. This project demonstrates safe management, validation, and restoration of YAML configuration files with automatic backup and corruption recovery.

Features

• Generic config manager for any struct
• Automatic validation of required keys and types
• Periodic config health checks and auto-restore from backup
• Simulated config updates, corruption, and random key injection for testing
• Thread-safe access and updates

Getting Started

Prerequisites

• Go 1.18 or newer

Installation

Clone the repository:

git clone https://github.com/dimalukas/go-config-manager.git
cd go-config-manager

Install dependencies:

go mod tidy

Usage

Run the example app:

go run main.go

This will:

• Load and validate config.yaml
• Restore from config.backup.yaml if the config is invalid or corrupted
• Periodically print the config, simulate updates, inject random keys, and corrupt the config file to demonstrate recovery

Project Structure

• main.go: Example usage and simulation routines
• config_manager.go: Generic config manager implementation
• config.yaml: Main configuration file
• config.backup.yaml: Backup configuration file
• go.mod, go.sum: Go module files
