How to Integrate Prometheus with Alertmanager for Advanced Alerting (Beyond Basic Grafana Setup)

October 12, 2026 by Jeff Wilson

In this tutorial, we will explain how to integrate Prometheus with Alertmanager for advanced alerting on Ubuntu 26.04. Prometheus is an open-source monitoring system that collects metrics from servers, applications, and services, while Alertmanager is responsible for processing, grouping, and sending notifications whenever an alert is triggered. Together, they provide a complete monitoring solution that helps administrators detect problems early and respond before they affect production environments. Alertmanager supports multiple notification channels, including email, Slack, Microsoft Teams, PagerDuty, and webhooks, making it suitable for both small deployments and enterprise infrastructures.

Learning to integrate Prometheus with Alertmanager on Ubuntu 26.04 is a straightforward process that can be completed in about 20 minutes. Let’s get started!

How To Set Up a Firewall with UFW on Debian 13

October 7, 2026 by Jeff Wilson

A firewall is a security system that controls inbound and outbound access to a system. On a Linux server, a firewall is a crucial component to add as a security measure. In general, a firewall can be either hardware or software that prevents unauthorized access and protects the network from threats such as malware, DDoS attacks, and hacking. UFW is an iptables front-end feature in Debian 13 that can be used to configure a firewall system. UFW filters data and creates rules about what data can enter or exit a computer system. In this guide, we will show you how to set up a firewall using UFW (Uncomplicated Firewall) on Debian 13.

How to Deploy Multi-Container Applications with Docker Compose on Debian 13

October 5, 2026 by Jeff Wilson

In this blog post, we will show you how to Deploy Multi-Container Applications with Docker Compose on Debian 13 OS. Docker Compose is a tool that helps you define and manage multi-container applications with a single configuration file called docker-compose.yml (or compose.yml). Instead of starting each container separately, you describe all the services, networks, and storage they need in one file, then launch everything with a single command. This makes development, testing, and deployment much simpler and more consistent. Multi-container applications use several containers that work together, such as a web server, a database, and a caching service. Each container has its own role, but they communicate through Docker networks to function as a single, cohesive application.

Configuring Multi-Container Applications with Docker Compose is a straightforward and can take up to 15 minutes. Let’s get started!

How to Set Up Traefik as a Reverse Proxy with Automatic SSL

September 30, 2026 by Jeff Wilson

In this blog post, we will show you how to set up Traefik as a Reverse Proxy with Automatic SSL on Linux. Traefik is a modern reverse proxy and load balancer that routes incoming web traffic to the correct backend services based on rules such as domain names, paths, or ports. One of its standout features is automatic SSL/TLS certificate management through Let’s Encrypt. Instead of manually generating, installing, and renewing certificates, Traefik requests valid SSL certificates, configures HTTPS, and renews them before they expire. This ensures secure communication between users and applications with minimal administrative effort. Traefik also integrates seamlessly with Docker, automatically detecting new services and updating routing rules. As a result, it simplifies deployment, improves security, reduces maintenance, and provides reliable traffic management for modern cloud-native applications.

To set up Traefik as a reverse proxy with automatic SSL on Linux, the most efficient method is using Docker Compose. This method leverages Traefik’s native Docker provider to automatically detect containers and provision Let’s Encrypt SSL certificates using TLS challenges.

How to Set Up Basic ELK Stack (or Lightweight Alternative) for Log Management on AlmaLinux 10

September 28, 2026 by Jeff Wilson

In this blog post, we will show you how to set up a basic ELK stack for Log Management on AlmaLinux 10. The ELK Stack is a popular open-source solution used for log management, monitoring, and data analysis. It consists of three main components: Elasticsearch, Logstash, and Kibana. Logstash collects and processes log data from various sources, such as servers, applications, and network devices, before sending it to Elasticsearch. Elasticsearch stores and indexes the data, enabling fast and efficient searches across large volumes of logs. Kibana provides an interactive web interface that lets users visualize log data with dashboards, charts, and graphs, making it easier to identify trends, troubleshoot issues, and monitor system performance. Together, the ELK Stack helps organizations centralize logs, improve operational visibility, detect security threats, and resolve problems quickly, making it an essential tool for modern IT infrastructure and log management.

A basic ELK stack on AlmaLinux 10 is straightforward to set up and will take around 15 minutes. Let’s get started!

How to Install and Use Portainer for Docker Container Management on Ubuntu 26.04

September 23, 2026 by Jeff Wilson

In this blog post, we will show you how to install and use Portainer for Docker Container Management on Ubuntu 26.04 OS. Portainer is a lightweight container management platform that provides a web-based graphical interface for managing container environments. It simplifies tasks such as deploying applications, monitoring containers, managing images, networks, volumes, and user access without relying solely on command-line tools. Portainer works with Docker by connecting to the Docker Engine API, allowing users to create, start, stop, and manage Docker containers through an intuitive dashboard. It is especially useful for beginners, teams, and administrators who want to streamline container management while improving visibility and operational efficiency.

To install and use Portainer on Ubuntu 26.04, you must install Docker Engine first, create a persistent data volume, and then deploy the Portainer Community Edition (CE) container. Let’s get started!

How to Install Symfony PHP Framework on Ubuntu 26.04
