🔥🔥🔥Containers from Scratch🔥🔥🔥
This is write up for talk I gave at CAT BarCamp, an awesome unconference at Portland State University. The talk started with the self-imposed challenge “give an intro to containers without Docker or rkt.”
Often thought of as cheap VMs, containers are just isolated groups of processes running on a single host. That isolation leverages several underlying technologies built into the Linux kernel: namespaces, cgroups, chroots and lots of terms you’ve probably heard before.
So, let’s have a little fun and use those underlying technologies to build our own containers.

Запускаем systemd в контейнере
Мы давно следим за темой использования systemd в контейнерах. Еще в 2014 году наш инженер по безопасности Дэниел Уолш (Daniel Walsh) написал статью Running systemd within a Docker Container, а еще...
This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications.

Building containers without Docker
In this post I'll outline several ways to build containers without the need for Docker itself including buildkit, kaniko, GitHub Actions, GitLab and Jenkins

Inotify in Containers
It is usually necessary to watch for any changes in file systems, both in development and in production modes. For example, in the development mode Webpack can watch files and recompile whenever they change; in the production mode Consul Template can watch…
