Containers From Scratch • Liz Rice • GOTO 2018

Absolutely eye opening. Now it all makes sense.

For anyone that landed here from the docker 101 tutorial, if you don't know some linux basics you can skip this video as probably you won't understand that much what's going on...

Aside from that this was a great demo on how containerization works :=)

MINDBLOWING

This is like the movie Inception, mind blowing!

Brilliant exposition. Masterful balance.

For the first time, I'm seeing how container works in behind the scenes. Excellent explanation, with no boredom. Thank you to the Presenter and the Organizer.

Seriously one of the best videos on the topic! So much info made so simple. I'm searching for all your other presentations :)

Me trying this on an ubuntu, in a Docker contianer.

I'm sure the content is great but the video is shaking and the voice-recording hollow, how can I get the transcript instead?

That's a pity that some people almost cover her voice, though. Made it harder to understand.

amazing

Such an informative talk and a wonderful demo that steps things up slowly!

Love the talk. Very insightful. Thank you

I'm a bit late to the party, but that was really amazing!

This was very detailed which is great, but it seems as though a deep knowledge of Linux is required? Most of this went straight over my head. Those directories full of properties? None of that made any sense.

Sensational! Never saw such brilliant explanation built up from the ground. Love it!

What a brilliant explanation.

I am new to linux/unix systems.
And from the speaker's knowledge I can clearly see that in order to do all these you have to have knowledge of 2 things:
1. go's capability of interacting with host operating system.
2. Linux system in-depth understanding

Can anyone suggest best resource which I should read and practice get such an in-depth understanding of linux/unix system?

Simply said, great video!

This Lady is a Legend :)

Amazing talk. Clear and brilliant. 5 Stars

This is an amazing session. I like the way Liz explained the underlying concepts of containers from basic Linux concepts.

What an absolute gem to the community, transcribed and explained in such a way that a novice and a scholar in this realm can gather and rejoice in such an eloquent speech. The future is in good hands; If (Mrs.) Rice presentation is given to those looking to expand there knowledge. Thank you truly to all those involved in making this possible a WONDERFUL Masterclass.

excellent presentation. God bless

more confused than when I started.

oh man.. I was checking the video in a fast manner until I saw that :(){ :|: & };: command. I executed it in my terminal which wasn't so much fun :D

amazing!

If only I can like multiple times

Great presentation

Amazing!! If you really want to understand containers this video is mandatory!👏

Just a kindly remind you must run this strictly in Linux and root user, WSL and MacOS does not work. if you do not have a linux on hand, suggest to run virtual machine

Awesome! Had been using docker all these days. I can now create my own docker.

Gemini 1.5 Pro: This video is about containerization and how it works.

The speaker, Liz Rice, starts the video by asking the audience how many people in the room are familiar with containers. She then goes on to explain what containers are and how they work. Containers are a way of packaging up a piece of software along with all of its dependencies so that it can run on any system. This is done by using namespaces and control groups. Namespaces limit the view of a process of the things that are going on on the host machine. Control groups limit the resources that a container can use.

Rice says that in order to understand containers, you need to understand three things: namespaces, control groups, and cgroups file system. Namespaces are a way of limiting what a process can see. For example, a container can have its own hostname and its own set of processes. Control groups are a way of limiting the resources that a container can use. For example, a container can be limited to a certain amount of memory or CPU. The cgroups file system is a way of configuring control groups.

Rice then goes on to show how to create a container from scratch. She starts by creating a simple Go program that can run an arbitrary command. She then uses namespaces and control groups to limit the resources that the container can use. Finally, she shows how to run the container.

The video ends with Rice answering a few questions from the audience. One question is about whether it is a good idea to run Docker in Docker. Rice says that there are very few occasions where you would need to do this, and that it is generally not a good idea. Another question is about how containers work with Java. Rice says that she is not a Java expert, but that she believes that the Java Virtual Machine would be grabbing a bunch of memory up front and then dividing that up in different ways that the kernel is no longer aware of.

Overall, this video is a great introduction to containers and how they work. It is a bit technical, but it is easy to follow if you have some basic understanding of Linux.

💯

This is a great talk and it would have deserved significantly better Audio quality.

This is absolutely very insightful presentation on the actual working of containers.

How did she get the ubuntu-fs?

this was one of the best videos i watched in a while

this was so great

Learned more about linux processes in this <45 minute video than I did in a whole Operating Systems course! Absolutely beautiful!

Say "hostinger" again, I dare you, I double dare you..

loved every minute of it

wow

Did i understand something wrong, or does she have 9 exabytes of storage available?

Watching this is like having a magician show you how he does his trick. Really awesome way to demystify containerization. Thank you so much!

This is awesome. Doing what so many people can’t seem to do - explain it clearly at a low level

Very good demonstration. Teach us from 0 to 1

I really enjoyed the presentation!
