Very thorough and detailed explanations inside the mechanics of Docker, ( i am at the first project) All instructors explain only docker ps docker images docker rmi u went deep explaining the flags -q -f status=existed. Absolutely loved it!

By Stephen Davis on 4/8/2025

Andrei continually demonstrates his mastery of the Linux operating system. With his three primary courses (Linux Administration: The Complete Bootcamp / Linux Security: The Complete Iptables Firewall Guide / this course) he gives you a sound, PRACTICAL APPLICATION experience to gain a sound understanding of how to do Linux systems administration. No other courses offered on Udemy or Coursera have I found that give you as thorough of an introduction, provide you with copious opportunities to practice the skills taught, and guidance on how to progress beyond the courses' material than these. I HIGHLY recommend to anyone interested in developing competency in working within the Linux operating system (both Debian and RHEL-based).

By Rafi Rajibsa on 3/9/2025

The hands on projects are good. But I have opinion about this course. I know this course is for someone who already has linux fundamental and trying to deep dive into real project. but most project in this course are using VPS in digital ocean or similar platform could work. but not all student have access to credit card to be able to register free account. secondly, some linux fundamental course are in Redhat or centos variant, so it makes the package and the command different than in this course. It would be good if this course updated and the teacher also write command for redhat or centos variant instead of ubuntu one. also a lot of package required for the lesson are not available for centos as well as installing via package. it requires more time to look around, and for someone who already expect and have scheduled learning hour, it messed up my schedule. I really hope this course can be updated to my opinion and I will be happy to change my rating

By Basics Development on 1/5/2025

The content is very relevant to many IT practioners. The explanations are ok though I don't always tend to find them straightforward and even lacking. I believe it's probably better to skip some of it or dive a bit deeper as it may lead to confusion. Overall, it's a great course. So far enjoying it.

By Zilkar Baranow on 7/11/2024

Rare to get a course with all this packed content where things work and make sense. The coach explains things really well and is one of the firsts that's always there responding questions. Already bought another few courses from him and am eager to start it out.

By Formgroup1 on 1/24/2024

I did not expect a course as good as this one. Instructions and explanations are very clear to understand and the instructor knows how to speak proper English. Overall, each project is a must to learn for an admin/sys :D

By Anonymized User on 9/20/2023

This course tells me the various knowledge of the Linux. It's easy to understand for me because of clear explanation. I gained confidence thanks to this good lecture and teacher. It would be perfect if there were "firewalld", the firewall system like iptables in this learning.

By Bryant Onojeta on 8/19/2022

So far I am about 1/2 completed with the labs, and this is all good information. I will keep updates coming as I progress through and at the end give my over all view point on this course. Overall so far this is a great course to learn.

By Mark Godley on 7/10/2022

If you have a passion for Linux and want a course with real world projects, this is highly recommended. If you are new to Linux, i would highly recommend that you complete the Linux Administration Bootcamp first. this is definitely not for beginners. Personally, i found the course well structured and delivered at a pace to suit my learning style with a significant amount of resource material available for support. If you do decide to jump in with limited linux administration knowledge i would strongly advise starting with the Bash scripting section as this will give you a good foundation of script building. combine this with much of the resources provided and you will be able to automate many of the installations required.

By Adnan Reza on 9/15/2021

Above and beyond of what I expected. Content was very relevant, concepts explained precisely. What I enjoyed the most was the presentation: the voice, the pace of talking, the explanation accompanied by direct lab result.
