"Kubernetes and Cloud-Native Associate (KCNA) Exam Guide" is a comprehensive introductory guide for anyone looking to prepare for the KCNA exam or to simply get started with Kubernetes and cloud-native. It will provide readers with the necessary fundamental knowledge to understand the Cloud Native Computing Foundation (CNCF) ecosystem, especially Kubernetes. The book covers all the exam objectives and much more.
The book includes prerequisite chapters for a better understanding of Kubernetes and cloud-native, core chapters based on the domains and competencies of the exam, and a couple of hands-on chapters. Readers will learn about containers, microservices, container orchestration, the internals of Kubernetes, container orchestration in Kubernetes, cloud-native architecture, observability, application delivery, and much more. Each chapter also includes practice questions at the end. Additionally, through hands-on exercises, readers will gain practical experience on Dockers and Kubernetes. Throughout the book, readers will learn about various cloud-native tools and technologies.
The concepts and topics covered in this book will empower readers to come up to speed with the cloud-native world and bolster confidence for taking up the KCNA exam. This book serves as an important resource for the KCNA exam, providing complete coverage of all the exam objectives.
Key Features:
- Explains core Kubernetes concepts and container orchestration in detail.
- Prepares you for the KCNA exam with comprehensive coverage, practice questions, and exam tips.
- Covers all five exam domains and competencies i.e., Kubernetes fundamentals, container orchestration, cloud-native architecture, cloud-native observability, and Cloud-Native Application Delivery.
What you will learn:
- Basics of Kubernetes and cloud-native, including related concepts such as microservices.
- Container fundamentals and the need for container orchestration.
- Hands-on container management with Docker and containers.
- Kubernetes architecture, resources, and API insights.
- Key cloud-native principles, tools, and roles.
- CI/CD, GitOps, and app delivery strategies.
- Exam preparation and practical Kubernetes setup.
Chapter 1: Stepping up to Kubernetes and Cloud-Native - This chapter acts as a warmup session covering concepts such as monolithic and microservices architecture, virtualization, cloud computing and containers that are important to map the world of Kubernetes and cloud-native. It also introduces Kubernetes and its origins, cloud native and its landscape, and cloud-native certifications. It also provides certain insights into the adoption of Kubernetes and cloud-native technologies and their importance as a skill for career growth.
Chapter 2: Understanding Containers and the Need for Container Orchestration - The second chapter goes a bit deeper into containers, how they work and the need for container orchestration. It covers Docker and container concepts, such as images, registry, runtime, including how storage, networking and security works on standalone containers, highlighting the challenges and paving the way for an introduction to container orchestration. Following this, the chapter covers a typical container orchestraor architecture, workflow, its functions and advantages. The chapter also covers open standards that are important to make everything work, followed by an introduction to the Kubernetes as a container orchestrator.
Chapter 3: Hands-on Docker and Containerd - This chapter provides hands-on exercises covering Docker installation, creating a Dockerfile, and running containers. Exercises also cover image registry, Docker hub, working with Docker volumes, and networking. The second part of the chapter covers similar exercises for Containerd, which is the default runtime for Kubernetes.
Chapter 4: Kubernetes Basics - This chapter covers the first exam domain, Kubernetes Fundamentals, covering Kubernetes architecture and the components that make up the control plane and the worker nodes, Kubernetes resources, scheduling, and the Kubernetes API. It also covers different Kubernetes installation methods.
Chapter 5: Container Orchestration with Kubernetes - This chapter covers the second exam domain, container orechestration, and covers how to secure, network, and store data in Kubernetes clusters. It covers Kubernetes resources or API objects that provide these capabilities and Service Mesh, an important technology concept for running microservices in a cloud-native model.
Chapter 6: Cloud-Native Architecture - This chapter covers cloud-native architecture fundamentals and the tenets of one, such as scalability, loose-coupling, resiliency, autoscaling, security, etc. The chapter covers how to implement these in Kubernetes using first class resources or external tools. The chapter also covers Serverless. Finally, it revisits community and governance, open standards, and cloud-native roles, covering the third exam objective, cloud-native architecture.
Chapter 7: Cloud-Native Observability - This chapter explores what cloud-native observability is, covering topics such as telemetry, instrumentation, monitoring, metrics, logging, and events. It provides information on the native observability options in Kubernetes and then introduces cloud-native observability tools designed for it, such as Prometheus, Grafana, Jaeger and more. This chapter also covers cost management, thus addressing the topics in the exam domain cloud-native observability.
Chapter 8: Cloud-Native Application Delivery - This chapter covers topics from the Cloud Native Application Delivery exam domain such as CI/CD, GitOps and GitOps tools like Flux and ArgoCD.
Chapter 9: Hands-on Kubernetes - This chapter teaches how to install Kubernetes using minikube, understand the environment, create and manage Kubernetes resources, basic operations, and troubleshoot through a series of hands-on exercises. This is not a requirement for the exam but greatly reinforces the learnings.
Chapter 10: About the Exam - This chapter provides information about the KCNA exam, such as the duration, number of questions, passing score, and other facts. It also includes information on how to prepare for taking the exam (before, during, and after), how to book the exam, the proctoring method, and more.
Who this book is for:
If you want to build a strong foundation on Kubernetes either to prepare for the KCNA exam or simply to get started in the cloud-native world, then this book is for you. The book is a great fit for a broad range of personas, such as recent technology graduates, developers, system administrators, aspiring DevOps engineers and SREs, cloud consultants, platform engineers, solutions architects, etc., regardless of their experience.
