Awesome! Took long time to watch it, lot of information in 30 minutes. I would have to watch multiple times to understand it, since I am kind of new to this! Thanks for the demos as well. They make it easier to understand : )
minor correction: the procfs links to namespaces aren't symbolic links, even as they look like them. They're something else because they have a reference counted relation to the nsfs where the namespace inodes (numbers) are allocated and released. By bind mounting these references, you can keep process-less namespaces alive, which you cannot do using symbolic links: the namespaces would be garbage collected.
To execute redis binary on the host, is it necessary to enter mount ns? What about just doing sudo /proc//exe without nsenter, it does the same, because exe is really a symbolic link to the redis-binary on the container file system, amazing video in between, so good to watch with everything explained clearly and crisply.
Reading from a script and no explanations? I can do that too. If I put each of your chapters into chatGPT I get more informative explanations than this mess of a presentation...
3 years later; this is still an excellent overview.
this is the best explanation of cgroups i have seen so far, seeing things makes understanding them so simple 👍
I am currently trying to understand cgroups and found this jewel. It makes the concept Crystal clear
1:20 Container primitives
2:20 Control groups
10:13 Namespaces
20:40 Container image
31:00 Container runtimes
Best deep dive for Docker i have found so far
Super! A lot covered in 30+ mins. I needed to stop several times because it gold what’s in there.
Very intuitive. Must watch for all the software engineers working in the current virtual software world
By far the best (and there are many) explanation I could find on the internet. Detailed yet clear and great precise narration.
I cannot explain how useful this is. Thank you sincerely.
Advance level details coupled with demos - great job.

Eye opening video. Advanced and most importantly - understandable.
One of the best video i ve seen about cgroups
the introduction to cgroups were great.
This is such an awesome explanation! Thanks Sam!
Great demos and explanations!

thanks! it is packed with info and I had to pause multiple times to digest it. (I was a little confused by unshare syscall and unshare util....
Need to watch it again with focus
This was excellent. Thank you!
Nice Nice ! Good job !
minor improvement would be to highlight the dir-names during your demo so people can spot them faster.
Excellent! Thank you, Sir.
Awesome talk, thank you very much!
I can only understand some about the cgroup parts. The rest are too unfamiliar for me. You guys can understand all 3 sections?

If it is possible please provide the same style video about hooks for the container, how play on them. thanks
Thank you very much, great content.
thank you sir!, this has been a great explanation!
Thanks, great explanation :)
this was awesome - thanks!
Thanks! This was useful to me!
That was awesome 🤗
Bit late, but I loved your video.

Excellent!
Thanks. I love your explanation. I give me to understand more. Do you have your own youtube channel that I can subscribe it?
