The Anatomy of a Container: The KernelCategory: Docker, Architecture
Welcome to this tutorial series, where we will evolve from the anatomy of a container inside the Linux Kernel, and will keep building pieces and evolving until the publication of a service into an Orchestration Platform.
In this first article, we will start to understand what is a container, to create the proper mindset when working with it. This is important for troubleshooting and architecture principles, where you need to understand well how something works, and in this context, container.
The Virtual Machines perspective comes from the Bastion vision, each process by itself has an Operational System to run their applications, and this is what we call full virtualization.
Doing some hands-on, is possible to understand this theory: If we run in any Linux system this command, you will be able to check-in each namespaces, a given process runs: Inside the virtual /proc filesystem, lives the runtime of Kernel.
