The automation layer that keeps modern infrastructure running: containers you can ship anywhere, services that restart themselves, jobs that fire on a schedule, and pipelines that build and deploy while you sleep. This track connects the everyday Linux commands you already know to the tools that turn a single server into a system.
Copy-paste ready and verified on Ubuntu 24.04 and Debian 12. The DevOps library is growing — here's what's live now, plus the fundamentals every automation task builds on.
Six ways to leave a container — and the crucial difference between stopping it and simply detaching so it keeps running in the background.

read the guide →apt search to Find a PackageProvisioning a build agent or a runner starts with knowing exactly what package to install. Seven ways to search the repos, minus the noise.
read the guide →Dedicated walkthroughs for systemd unit files, cron and systemd timers, Docker Compose and a first CI pipeline are being written and reviewed right now. New DevOps guides land on Linuxier regularly — bookmark this page or follow along on the blog.
Containers package your app, systemd keeps long-running processes alive, cron and timers handle the recurring work, and CI ties commits to deployment. Each guide is written so the previous one isn't a prerequisite — start with Docker if that's your pain point today, or build up from the shell if you're new.
DevOps overlaps with Networking (ports, DNS, checking what's listening) and Security (hardening the hosts your pipelines deploy to). If you're just getting comfortable in the terminal, begin with Linux Basics.
