The document discusses Kubernetes, an open-source system for managing containerized applications across multiple hosts. It provides an overview of what Kubernetes can do, including container scheduling, load balancing, and restarting containers, and what it cannot do, such as multi-tenant support and high availability. It also describes how the author tried out Kubernetes using CentOS, Docker, etcd and flannel to run the cluster.
The document discusses Nouka, an open source inventory management tool for Linux. Nouka consists of three parts - Nouka data collector, Naya data store, and Yaoya data converter. Nouka data collector runs commands periodically on Linux machines and sends the results to Naya data store. Naya uses Fluentd and MongoDB to store the collected data. Yaoya then converts and outputs the data in various formats like JSON, CSV for analysis. Overall, Nouka provides an automatic and periodic way to collect and centralize inventory data from Linux machines.

IoT Devices Compliant with JC-STAR Using Linux as a Container OSTomohiro Saneyoshi
?
Security requirements for IoT devices are becoming more defined, as seen with the EU Cyber Resilience Act and Japan’s JC-STAR.
It's common for IoT devices to run Linux as their operating system. However, adopting general-purpose Linux distributions like Ubuntu or Debian, or Yocto-based Linux, presents certain difficulties. This article outlines those difficulties.
It also, it highlights the security benefits of using a Linux-based container OS and explains how to adopt it with JC-STAR, using the "Armadillo Base OS" as an example.
