This has to be the first material any newcomer like me, to cgroups and namespaces encounters. Then read or listen to others to get more details. Merci beaucoup Monsieur !
The moment slides are replaced by the speaker, the line of thought/understanding is lost. The slides must be visible all the time. Great talk but bad camera placement.
great talk. please persistently show the slides rather than full screen only to the presenter. sometimes it is hard to corresponds his explanation to the bullet points.
could someone explain or recommend something to read for understanding what and why is going on there with mount/unmount commands in demo project in the end.
I don't mean to be disrespectful but this was 45 minutes of lame ass slides and jokes followed by 8 minutes of pure gold. I would have loved to have 53 minutes of that powerful demonstration. If anyone reads this and knows a place where this man demonstrates slowly and explains how to create the illusion of a container using Linux commands and all the other cgroup layers then please reply to this comment. Very impressive.
can someone help to explain why there is ubuntu and alpine docker image? how can ubuntu / alpine linux distribution live inside container? I dont understand!!!!
in my mind - yes. cgroups are still cgroups, namespaces are namespaces, copy-on-write is copy-on-write. Can't see anything major changing there? Could be wrong, if so I hope someone corrects me, but I think the main innovation since this video went into container orchestration and everything that came out of that
Not sure who really needs to know this stuff. If you're planning on creating the next Docker Corp maybe it's useful. If you merely want to use Docker.... I imagine pretty much none of this stuff is needed.

For 8 years since this video came out. And still he is the only one who explained docker really well
thank you very much
And it was fun (in the good way)
Did you watch Liz Rice at ContainerCamp? I think that was pretty neat as well, but works better if you're somewhat familiar with Go
After 4 years, this is one the best talks about docker
I'm a Docker noob: after 4 years, does this video still say valid things? Behind the scenes, Docker is still working as this guy say?
@@24Shredder yes, fundamentals never change

Saw this in 2020 unfortunately. This talk is so awesome. Should have saw this before.Thanks Jerome!
This is so interesting, simply the best, in this presentation i get to understand how docker works under the hood.
This is the best place to start for someone coming from Linux
This was such a good presentation
The moment slides are replaced by the speaker, the line of thought/understanding is lost. The slides must be visible all the time. Great talk but bad camera placement.
Also too much text in slides. Trying to listen to him talk fast and read at same time. Otherwise great informative presentation
Great talk. Went far further than most materials on (pure) docker. (and containers in general)
Very well presented. Thank you for uploading!
Awesome one. Loved it

What a fantastic talk!
awesome talk. thank you ☺️

Thanks for sharing
Funny that cgroups2 allows now to control percentage as well.

first chapter of Containerization with LXC by Konstantin Ivanov has it like that.
Thank you for this talk! By curiosity, are there open-source or on-the-market container runtimes that are not based on namespaces and cgroups ?
Yes. One example is Kata. It’s uses virtualisation to run containers. It’s open source.
Awesome talk! thanks for uploading the vid.
great speach!
❤ and gratitude
can someone help to explain why there is ubuntu and alpine docker image? how can ubuntu / alpine linux distribution live inside container? I dont understand!!!!
Excellent!!!
Very informative, thanks.
Bawandarful! Got to learn a lot about Linux kernel.
Are there more details on the page overhead accounting (at 13:16)?
Specifically what boot time (or kernel config) options disable it?
Great talk! Very informative
Thank you !!!
Really informative :)
it is too complex to understand without a specilized backgroun. Anyone knows a refrence to start with understanding what he meant???
I know right... You gotta be a kernel Hacker to know all of this...
Great
is this video is still relevant in 2020?
in my mind - yes. cgroups are still cgroups, namespaces are namespaces, copy-on-write is copy-on-write. Can't see anything major changing there?

This is clearly not for everyone
sure it's not, understanding it requires some essential knowledge of OS concepts and mechanisms (especially Linux in this case)
couldn't fully follow the demo
skill issue
That rude comment about systemd-nspawn maintainers at 37:15 was really childish and unprofessional.
Beside that a very good presentation.
it was funny
Funny how podman basically makes systemd a key part of local container management.
#2:55 - Container can be like VM ... that's the way how LXC works ... intended is *Docker is not like VM* .
Nobody has broken out of OpenVZ ... then obviously it's so uninteresting that people even don't bother.
