A production-ready collection of Bash automation utilities designed to help DevOps Engineers automate routine operational tasks across Ubuntu Linux servers and AWS EC2 environments.
A production-ready collection of Bash automation utilities designed to help DevOps Engineers automate routine operational tasks across Ubuntu Linux servers and AWS EC2 environments. The toolkit focuses on infrastructure auditing, service management, storage analysis, network validation, and backup automation through modular, production-oriented shell scripts that can be executed independently or integrated into existing operational workflows.
Each utility addresses a specific aspect of day-to-day infrastructure operations, enabling engineers to perform server health assessments, audit network configurations, monitor critical services, analyse storage utilisation, and manage backup lifecycles using a consistent command-line interface. The scripts are designed to support common operational activities in development, testing, and production environments while remaining lightweight, reusable, and easy to customise for different infrastructure requirements.

The repository contains five modular Bash utilities that automate common DevOps operational tasks across Ubuntu Linux servers and AWS EC2 environments. Each script is designed to perform a specific operational function while remaining independent, allowing engineers to execute only the utilities required for a particular maintenance or troubleshooting task.
| Script | Primary Responsibilities | Purpose |
|---|---|---|
| 01-system-health-check.sh | Performs a comprehensive health assessment by collecting system information including hostname, operating system, kernel version, CPU utilisation, memory and swap usage, storage utilisation, system load, uptime, logged-in users, running processes, and directory structure. | Provides a quick operational overview of the server's health before troubleshooting, maintenance, or deployments. |
| 02-server-network-audit.sh | Audits network configuration by collecting EC2 metadata, public and private IP addresses, network interfaces, routing tables, DNS configuration, internet connectivity, listening ports, and time synchronisation status. | Validates network connectivity and infrastructure configuration while assisting with troubleshooting and deployment verification. |
| 03-service-manager.sh | Monitors and manages critical DevOps services by checking service status, runtime engines, listening ports, Docker containers, application health, and optional restart operations. | Simplifies routine service administration and enables rapid identification and recovery of failed services. |
| 04-storage-manager.sh | Analyses filesystem utilisation, inode usage, storage devices, large directories and files, Docker storage, symbolic links, backup archives, core dumps, and optional cleanup operations. | Helps prevent storage-related incidents by identifying capacity issues and safely reclaiming disk space. |
| 05-backup-manager.sh | Creates, verifies, restores, rotates, and manages compressed backup archives while maintaining backup integrity and retention. | Provides a reliable backup and recovery solution for protecting infrastructure configurations and application data. |
The scripts are organised according to real-world operational workflow followed by DevOps Engineers during routine infrastructure maintenance and troubleshooting.
01-system-health-check.sh– Verify the overall health and operational status of the server.02-server-network-audit.sh– Validate network configuration, connectivity, routing, DNS, and listening ports.03-service-manager.sh– Inspect and manage critical services and applications running on the server.04-storage-manager.sh– Analyse storage utilisation, filesystem health, and perform optional cleanup tasks.05-backup-manager.sh– Create, verify, restore, and manage backups after confirming the server is healthy.
Before using these scripts, ensure the following requirements are met:
- Ubuntu Linux 22.04 LTS or later.
- Bash shell.
- Sudo privileges for operations that require elevated permissions.
- Internet connectivity for external network validation and package installation (where applicable).
- AWS EC2 instance (recommended for scripts that utilise EC2 metadata services).
- Common Linux utilities such as
curl,systemctl,ip,ss,tar,find, anddf.

The 02-server-network-audit.sh utility performs a comprehensive network audit by collecting infrastructure inventory and validating the network configuration of Ubuntu Linux servers and AWS EC2 instances. It is designed to help DevOps Engineers quickly assess network connectivity, verify cloud metadata, inspect routing configuration, and identify potential networking issues during troubleshooting or deployment activities.
The audit includes:
- Hostname and operating system information
- CPU and memory information
- AWS EC2 instance metadata (IMDSv2)
- Public and private IP address discovery
- Network interface inspection
- DNS configuration
- DNS resolution tests
- Internet connectivity validation
- Routing table inspection
- Listening ports audit
- System time synchronisation

The 03-service-manager.sh utility audits, monitors, and manages critical DevOps infrastructure services running on Ubuntu Linux servers. It enables DevOps Engineers to verify service availability, inspect runtime engines, validate listening ports, restart individual services, and automatically recover failed services through a single operational utility.
The utility supports the following operations:
- Audit the health status of all configured DevOps services
- Check the status of a specific service

The Server Operations Toolkit demonstrates how common infrastructure management tasks can be standardised and automated using modular Bash scripts. Each utility focuses on a specific operational responsibility while following a consistent command-line interface, making the toolkit easy to understand, extend, and integrate into existing workflows.
Whether performing routine health checks, auditing network configurations, managing critical services, analysing storage utilisation, or protecting infrastructure through automated backups, the toolkit provides practical examples of production-oriented Linux automation and operational best practices.
These utilities are designed using real-world DevOps workflows and can be adapted for development, testing, staging, and production environments with minimal modification. The scripts may also serve as reusable building blocks for CI/CD pipelines, scheduled maintenance tasks, configuration management, and day-to-day infrastructure operations.
Contributions, enhancements, and suggestions are welcome as the toolkit continues to evolve with additional automation utilities and operational capabilities.
