Multi-stage builds are one of the most powerful features in Docker, allowing you to produce lean production images by separating the build environment from the runtime environment. On RHEL 8, where production image size and attack surface matter, multi-stage builds reduce final image size dramatically by discarding build tools and intermediate artifacts. This tutorial walks […]
Introduction This guide explains how to Set Up Uptime Kuma on FreeBSD 12 on FreeBSD 12. FreeBSD uses the pkg(8) binary package manager, rc.conf(5) for service startup configuration, and pf(4) as its primary packet filter. There is no SELinux or AppArmor — instead, FreeBSD provides the MAC (Mandatory Access Control) framework and Capsicum for fine-grained […]
Introduction FreeBSD 13 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up tune kernel parameters with sysctl on freebsd 13 on FreeBSD 13 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from any […]

Introduction Deploying set up iscsi on freebsd 13 on a FreeBSD 13 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax. This tutorial stays entirely within the standard base […]
