What is Container Operating System: Immutable, Auto-Updating, Security Minded Fedora CoreOS Intro
Переглядів 24,270
3 роки томуWhat do you need to run containers in production? Linux kernel? Container manager? Some security features built-in? Is there anything else?
One of the trends in cloud native world is to run specialized Container Operating Systems that are purpose-built to run containerized workloads. Started with CoreOS, continued with RancherOS and others, we now have plenty of better options to choose from.
In this video, we will look at what Container Operating Systems are and we will see one of them, Fedora CoreOS, in action. We will see what is OStree and rpm-ostree, Ignition configuration and how to run Fedora CoreOS on AWS with ECR.

Hey thanks for the really simple introduction to the topic. Plan on making more videos on this topic? Q: If the file system is immutable, do we need to reboot our system evverytime we want to run a new container (from new image)? If not how does it work then.

There will be more videos for sure, stay tuned - and feel free to drop us ideas of what you would like to see covered in next videos. You do not need to reboot when you run containers - its immutable, but not _compete_ filesystem. There is a /var/xxx folders that are writeable and this is where containers are stored. It's bit more complex that just "read only on /". I was thinking about doing a detailed video on OSTree and show this tricks.. should I? :)

@@Fodoj Yep thanks for the clarification, makes more sense now. I would love more content on these topics. As of now everything related to COS is scattered across web and honestly not so easy to follow. I'd be definitely interested in os-tree and I'm pretty sure I'm not the only one here.

It will be useful to share links from the video in its description.

Видно не вооружённым глазом, что всю эту мишуру (управление и установку, накатывание обнов, да просто все эти конфиги ручные пересоздаваемые руками по миллиону раз и т.д.) можно сделать проще. Но никто не делает. Почему? - а потому, что: "тогда за что деньги брать?"
