"Kubernetes Observability in Action" is an essential guide for professionals looking to enhance their understanding and capabilities in monitoring and troubleshooting Kubernetes environments. This book delves into the fundamental techniques and tools necessary for achieving deep observability in Kubernetes clusters, leveraging the powerful features of eBPF, Cilium, and Grafana.
Take part in a thorough learning process that will help you understand not only the details of Kubernetes observability but also how to implement an initial observability platform. Use the combined power of K8s, Cilium, Grafana, Tempo, and Loki according to the guidance of a skilled professional to build a strong observability infrastructure.
“Kubernetes Observability in Action” is not just a book; it’s an exploration into the realms of Kubernetes, eBPF, and the powerful synergy of Cilium and Grafana. In these pages, readers will embark on a journey that transcends traditional observability, diving into the intricate layers of containerized environments. We’ll unravel the potential of eBPF (Extended Berkeley Packet Filter) as a game-changing technology, unlocking unprecedented visibility into the inner workings of Kubernetes clusters. This book is not just a guide; it’s an invitation to master the art of observability and elevate your understanding of cloud-native landscapes.
Although packet filtering was the original purpose of BPF, it has since been improved to enable dynamic Linux kernel tracing. Now, for instance, a user can write a program related to cgroups that permits or prohibits access to system resources such as CPU, memory, network bandwidth, and other process groups. So, eBPF (extended BPF) is a new Linux kernel technology, which allows strong security visibility and control logic to be dynamically inserted within Linux. Cilium security policies can be applied and updated without requiring modifications to the application code or container configuration because eBPF operates inside the Linux kernel.
Within the digital universe of Kubernetes, achieving deep observability is akin to wielding a cosmic telescope that pierces through the layers of abstraction, revealing the inner workings of microservices and containers. “Kubernetes Observability in Action” empowers readers to harness the full potential of eBPF, a revolutionary technology that extends the traditional packet filtering capabilities of the Linux kernel. We’ll explore the integration of Cilium, a cutting-edge CNI (Container Network Interface), and Grafana, a versatile observability platform, to craft a comprehensive solution for monitoring and troubleshooting Kubernetes environments. As we navigate through practical implementations, readers will emerge equipped with the knowledge to elevate their observability game, ensuring their Kubernetes deployments operate at peak efficiency and resilience. Get ready to delve deep into the cosmic wonders of Kubernetes observability and redefine your approach to managing cloud-native architectures.
