Introduction This guide explains how to Install Netdata Monitoring on Debian 9 on Debian 9 Stretch. Debian Stretch 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 9 install with the standard […]
How to Install Podman as a Rootless Docker Alternative on RHEL 7 Podman is a daemonless, rootless container engine developed by Red Hat that is fully compatible with the OCI (Open Container Initiative) standard and largely compatible with the Docker CLI. Unlike Docker, Podman does not require a long-running background daemon running as root, which […]
Introduction Deploying configure zabbix agent on debian 9 on a Debian 9 Stretch 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, […]
How to Install Portainer for Docker Management on RHEL 7 Portainer is an open-source container management UI that puts a graphical interface in front of Docker, Swarm, and Kubernetes. Instead of memorising dozens of docker subcommands, Portainer lets you inspect containers, manage images and volumes, view real-time logs, open an in-browser terminal, and deploy stacks […]
How to Deploy Applications with Docker Compose on RHEL 7 Docker Compose lets you define and run multi-container applications using a single YAML file.

How to Set Up a Private Docker Registry on RHEL 7 Running a private Docker registry gives your team a secure, internal location to store and distribute container images without relying on Docker Hub or other public registries. Whether you are enforcing air-gapped security policies, reducing external bandwidth, or simply keeping proprietary application images off […]
Introduction This guide explains how to Install Prometheus on Debian 9 on Debian 9 Stretch. Debian Stretch 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.

Introduction How to Set Up psad Port Scan Attack Detector on Debian 9 is a fundamental operation for any administrator maintaining a Debian 9 Stretch server. Debian 9 Stretch 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 […]
How to Use Docker Volumes and Bind Mounts on RHEL 7 Containers are ephemeral by design — when a container is removed, any data written inside its writable layer is lost. Docker solves this with three types of persistent storage: named volumes, bind mounts, and tmpfs mounts. Named volumes are managed entirely by Docker and […]
