Awesome! Numerous interesting and useful things were discussed here. Things like podman, cockpit, dnf and other are described widely. I'm not sure if the terminal recording was that important. Personally, I'd change it to nftables which was introduced in CentOS 8. Nevertheless, It's one of the best courses I've seen.

I must say it's a very well thought course. The lecturer is explaining the contents clearly and precisely. Add on is also the possibility to double check what learned along with supporting material and labs. Well Done Excellent Work !!

Great match for what I was looking for. I needed to know the latest updates for CentOS 8 and this course provided that and more

Alberto22 March 2020

Good and complete course. Very funny,complete and clear with labs included. For me is a 5 star course.

I've been putting off diving into RHEL / CentOS 8 for too long - this course quickly brought me up to speed by providing a wonderful crash-course into everything that matters. Thank you, Patryk! I appreciate the labs and the means to have the toolset provided by All Open double-check the work automagically. They serve as a checkpoint after each section and provide a bit of hands-on to make the topics stick. OK, sure, a few weeks after the course you're back to reading man pages, but at least you know what to look for. PS: 3.5h can easily be stretched into a few evening's worth of fiddling with a CentOS 8 VM. ;-)

It is impressive coverage of the subject with detailed demonstrations and explanations by instructor with a real engineering background. And especially i would like to highlight the approach of processing the labs, which is making impression of the full interactive class. I enjoyed the course . I will be going through this course again because of the massive amount of material covered. I am glad I chose this course.
