Introduction Debian 12 Bookworm is built around the ethos of stability and free software. Setting up install cockpit web console on debian 12 on Bookworm leverages the same proven Debian packaging system that powers millions of servers worldwide, while benefiting from the latest upstream releases included in the Bookworm freeze. Follow each step carefully and […]
Introduction Deploying configure blackbox exporter for endpoint monitoring on debian 12 on a Debian 12 Bookworm machine is straightforward thanks to Debian’s policy-compliant packaging. Unlike rpm-based distributions, Debian stores configuration helpers in /etc/default/, uses update-rc.d for older init scripts, and provides dpkg-reconfigure for interactive package configuration. This tutorial stays on the systemd path throughout. Prerequisites […]
Podman is Red Hat’s daemonless container engine and has been the default container tool on RHEL 8 since its initial release. Unlike Docker, Podman does not rely on a long-running root daemon — each container runs as a direct child process of the user who started it. This means regular users can run containers without […]
Day-to-day Docker work revolves around a core set of commands for pulling images from registries, starting and stopping containers, reading logs, and cleaning up unused resources. Mastering these commands on RHEL 8 means you can confidently deploy, debug, and maintain containerized applications without relying on GUI tools. This tutorial covers the full lifecycle from pulling […]
Introduction Deploying set up nagios4 on debian 12 on a Debian 12 Bookworm machine is straightforward thanks to Debian’s policy-compliant packaging. Unlike rpm-based distributions, Debian stores configuration helpers in /etc/default/, uses update-rc.d for older init scripts, and provides dpkg-reconfigure for interactive package configuration. This tutorial stays on the systemd path throughout. Prerequisites Before you begin, […]
Persistent data is one of the most important concerns when running containers, since a container’s writable layer is destroyed when the container is removed. Docker provides three storage mechanisms to address this: named volumes managed by Docker itself, bind mounts that link a host directory directly into a container, and tmpfs mounts for ephemeral in-memory […]
Docker is not available in RHEL 8’s default AppStream repositories, so installing it requires adding the official Docker CE repository from Docker’s own package server. Unlike earlier RHEL versions, RHEL 8 ships with Podman as its native container runtime, but Docker CE remains a popular choice for teams migrating existing workflows. This tutorial walks through […]
Introduction How to Install Prometheus on Debian 12 is a fundamental operation for any administrator maintaining a Debian 12 Bookworm server. Debian 12 Bookworm ships with the Linux 6.12 kernel, updated toolchains, and a fully refreshed package archive — meaning version numbers, configuration file paths, and some dependency chains differ from Debian 12. This tutorial […]
Introduction This guide explains how to Apply CIS Benchmark Hardening to Debian 12 on Debian 12 Bookworm. Debian Bookworm uses systemd for service management, nftables as the underlying packet filter (with ufw or iptables front-ends still available), and AppArmor for mandatory access control. Every command is designed for a minimal Debian 12 install with the […]
