Understanding Cgroups

Containers have revolutionized the way we develop and deploy applications, providing a lightweight and portable solution to run applications consistently across different environments. In order to manage resources effectively in these environments, control groups or cgroups come into play. In this blog post, we will delve into the world of cgroups, explore their benefits, and understand how they function to enhance the performance of containerized applications.

UnionFS and Docker: Overview of Union File Systems in Containerization

UnionFS is a user-space, stackable file system that unifies multiple file systems, presenting them as a single cohesive file system. It plays a crucial role in containerization platforms like Docker, which use UnionFS to optimize storage, simplify backups, and efficiently manage resources. In this blog post, we’ll explore the relationship between UnionFS and Docker, discussing how they work together, providing an overview of the relevant commands in this context, and diving deeper into the specific features and best practices that make UnionFS an indispensable part of the Docker ecosystem.

Unraveling Docker: An In-Depth Exploration of Linux Kernel Features and Commands

Docker has profoundly impacted software development and deployment, offering containerization capabilities that simplify application management. The Linux kernel features that support Docker containers create isolated, resource-controlled, and efficient environments for applications. This blog post delves into the essential Linux kernel features at the heart of Docker containers: namespaces, cgroups, and union file systems. We’ll also examine Linux commands that provide insights into these features, giving readers a comprehensive understanding of Docker’s inner workings and the technologies that support it.
