Learn Linux & DevOps on YouTube

Why subscribe?

The Dargslan YouTube channel is the video companion to our book library and blog. We publish working, copy-pasteable tutorials on the topics IT professionals actually use day-to-day — no clickbait, no padding, no "sponsored deep dive" disguised as content. Every video is recorded in a real terminal, on a real Linux box, with the configurations and commands you can paste directly into your own lab.

What we publish

• Linux deep dives — systemd, networking, file systems, performance tuning, troubleshooting workflows.
• Container & orchestration — Docker, Podman, Kubernetes from first install to production patterns.
• Cloud & DevOps — Terraform, Ansible, CI/CD pipelines, GitOps with Flux and Argo.
• Security & hardening — SSH best practices, firewall configuration, intrusion detection, audit logging.
• Career playlists — companion videos for our certification study guides (RHCSA, LPIC, CKA, AWS).
• The 1% Better series — short, focused tips that compound into real skill over months.

The publishing schedule

We publish on a predictable rhythm so the channel stays useful as a learning resource, not just a feed.

• Mondays — full long-form tutorial (15–35 minutes), one core topic, complete walkthrough.
• Wednesdays — "1% Better" short (3–8 minutes), one tip, one command, one improvement.
• Fridays — Q&A or troubleshooting video built from the week's comments and email questions.

Subscribers with notifications enabled see every release the moment it goes live; the rest is collected into the weekly newsletter so nothing is missed.

How the channel pairs with the books

Every major video links back to the matching chapter in one of our eBooks for the deep written reference, and every book includes the matching playlist URLs in the appendix. The pattern we recommend:

1. Watch the video first — see the working configuration end-to-end in the terminal.
2. Read the chapter — understand why each step works, the alternatives, the failure modes.
3. Practice in your lab — replicate the setup on your own VM or container; break it; fix it.
4. Apply to production — only after step 3, with your team's review process.

This is the cycle that turns watching into actual skill.

Recommended starting playlists

• Linux Essentials in 30 Days — daily 8–15 minute videos for absolute beginners; finish in a month and you can administer a Linux server.
• Docker From Scratch — install, build, run, network, deploy. No prior container experience required.
• Kubernetes for Sysadmins — kubectl, manifests, networking, storage, troubleshooting; written for engineers who already know Linux.
• SSH Mastery — keys, agents, ProxyJump, ssh_config patterns, hardening, certificate authentication.
• Terraform & Ansible Workflows — real-world infrastructure-as-code patterns, including secrets handling and state management.
• Production Postgres — installation, replication, backups, monitoring, and the tuning that actually matters.

What you will not find on the channel

To set expectations clearly:

• No paid sponsorships disguised as tutorials. When a tool is featured, it is because we use it ourselves; sponsorships are disclosed in the description, not in the script.
• No "course launch" videos or upsell sequences. The eBooks are the paid product. The channel itself stays free, complete, and self-contained.
• No reaction videos, no news commentary, no drama. The channel is for technical work — tutorials, demonstrations, troubleshooting, certifications.
• No clickbait thumbnails. The thumbnail says what the video covers; the title matches the content.

Community & questions

Comments on every video are read by the same engineers who write the books. Questions answered in comments often become the next Friday Q&A video. The same applies to the contact form and to issues raised in the email newsletter — your real-world problems shape the next month of content.

For learners just starting out

If you have never administered a Linux box, never opened a terminal in anger, never deployed a container — start with Linux Essentials in 30 Days. Watch one short video per day, follow along in a free VM (we recommend a fresh Ubuntu Server or Debian install), and after thirty days you will be able to do real work. Pair it with our Linux for Beginners bundle for the matching written reference.

For experienced engineers

If you already run Linux in production, the channel still earns its place in your subscriptions. The 1% Better series, the troubleshooting Fridays, and the deep dives on systemd internals, network namespaces, eBPF, and the production Kubernetes patterns are written for people who have already crossed the basics. The certification playlists (RHCSA, LPIC-2, CKA, AWS SAA) are also valuable as structured refresher courses before exams.

One more reason to subscribe

Every video on the channel is free, ad-supported by YouTube only, and stays online indefinitely. There is no signup, no email gate, no "free trial." Subscribing simply tells YouTube to actually show you the next video — which, given how the platform works in 2026, is the difference between learning consistently and missing everything we publish.
