Learn what Terraform is, how to install it, and how to use it to manage your infrastructure declaratively.
Terraform: An Introduction to Infrastructure as Code
Terraform is one of those tools that once you try it, you’ll miss it when you don’t have it available. Instead of creating resources manually by clicking through consoles or running commands, you describe what you want in text files and Terraform takes care of creating it.
In this post, I’ll explain what it is, how to install it, and how to take your first steps with this essential tool for a DevOps engineer.
Emulate AWS services locally with LocalStack
LocalStack is an AWS service emulator that runs in a Docker container. With it, you can develop and test applications that use AWS without connecting to the real cloud, saving you costs and allowing you to work completely offline.
In this post, I’ll show you how to install and configure LocalStack in your homelab using Docker Compose, how to interact with the emulated services, and some practical examples.
Automatic log management with logrotate
Logrotate is a fundamental tool on any Linux system that automates log file management. Without proper rotation, logs can fill up disk space, degrade performance, and make troubleshooting difficult.
In this post, I’ll explain how to configure and use logrotate to keep your logs under control, with practical examples for your applications and services.
Web Interface for NUT with PeaNUT
PeaNUT is a modern and elegant web interface that lets us visually monitor UPSs managed by Network UPS Tools (NUT). With PeaNUT, we can check the status of our UPS devices intuitively from any browser.
In this post, I’ll show you how to install and configure PeaNUT using Docker and Docker Compose.
UPS Monitoring with Network UPS Tools (NUT)
Network UPS Tools (NUT) is an open-source toolkit that lets us monitor and manage UPS (Uninterruptible Power Supply) devices. With NUT, we can automate safe shutdowns of our systems in case of power failure, protecting our data and hardware.
In this post, I’ll show you how to install and configure NUT on your server, set up clients to receive UPS status notifications, and implement Telegram notifications.
