Hands-On Multi-Cloud Kubernetes
"Hands-On Multi-Cloud Kubernetes" is an essential guide for anyone looking to understand Kubernetes and how it can be used to manage multi-cloud infrastructure. With eight comprehensive chapters, this book provides hands-on experience in setting up Kubernetes clusters, administering deployments and updates, and working with AWS and GCP tools. Readers will learn to work with various powerful tools, including Helm, FluxCD, Virtual Kubelet, Submariner, and KubeFed. With GitOps principles and workflows, they will practice continuous delivery and learn to manage secrets and config maps. They will build and deploy serverless clusters using Virtual Kubelet and learn to scale them across multiple cloud environments. They will even be introduced to cross-cluster networking with Submariner, where they will learn to perform service discovery, load balancing, and monitor networking metrics. Managing multi-cluster Kubernetes can be a daunting task, but with KubeFed, readers will gain the skills necessary to set up and deploy multicluster federations, making it easier than ever to administer their own infrastructure. And with multi-cloud CI/CD pipelines using Jenkins, they will perform end-to-end multi-cloud operations, ensuring their code is delivered quickly and efficiently. Finally, the book covers security in Kubernetes, giving readers the tools and knowledge to configure RBAC, Kubernetes network policies, and secure data over Kubernetes clusters. They will even learn to use Open Policy Agent to manage compliance, ensuring that their infrastructure is powerful and secure. Key Learnings Learn Multi-cloud Kubernetes from fundamentals to advanced concepts and tools Setting up and managing Kubernetes clusters on multi-cloud infrastructure Working with powerful tools like Helm, FluxCD, and Virtual Kubelet Utilize Submariner for cross-cluster networking, service discovery, and load balancing CI/CD pipelines with Jenkins for end-to-end multi-cloud operations Practice GitOps principles and workflows for continuous delivery Building and deploying serverless clusters using Virtual Kubelet Managing multiple Kubernetes clusters as a single entity with KubeFed Security in Kubernetes with RBAC, network policies, and Open Policy Agent Table of Content Introduction to Multi-cloud Kubernetes Kubernetes Cluster Management and Deployment Using FluxCD Virtual Kubelet and Serverless Clusters Networking with Submariner MultiCluster Management and Federation Multi-cloud CI/CD Pipelines Security in Multi-cloud Kubernetes Audience This book is ideal for cloud professionals, the DevOps team, Kubernetes developers, and networking professionals to explore multi-cloud networking, working with multi clusters, deploying Kubernetes, and getting skilled with various innovative Kubernetes tools. Knowing cloud networking or Kubernetes is sufficient to begin with the book.
Cloud Native DevOps with Kubernetes
Kubernetes is the operating system of the cloud native world, providing a reliable and scalable platform for running containerized workloads. In this friendly, pragmatic book, cloud experts John Arundel and Justin Domingus show you what Kubernetes can do—and what you can do with it. You’ll learn all about the Kubernetes ecosystem, and use battle-tested solutions to everyday problems. You’ll build, step by step, an example cloud native application and its supporting infrastructure, along with a development environment and continuous deployment pipeline that you can use for your own applications. Understand containers and Kubernetes from first principles; no experience necessary Run your own clusters or choose a managed Kubernetes service from Amazon, Google, and others Use Kubernetes to manage resource usage and the container lifecycle Optimize clusters for cost, performance, resilience, capacity, and scalability Learn the best tools for developing, testing, and deploying your applications Apply the latest industry practices for security, observability, and monitoring Adopt DevOps principles to help make your development teams lean, fast, and effective
Hands-On Kubernetes, Service Mesh and Zero-Trust
A comprehensive guide to Kubernetes, Service Mesh, and Zero-Trust principles KEY FEATURES ● Delve into security practices that guarantee resilience and secure deployments. ● Discover strategies for managing Kubernetes clusters, enhancing performance, and achieving high availability and scalability. ● Acquire a conceptual understanding of the challenges faced in production environments and explore industry-standard solutions for efficient resolution. DESCRIPTION Building and managing secure applications is a crucial aspect of modern software development, especially in distributed environments. Kubernetes and Istio, when combined, provide a powerful platform for achieving application security and managing it effectively. If you want to build and manage secure applications with ease, then this book is an ideal resource for you. The book extensively covers the building blocks of the Kubernetes orchestration engine, providing in-depth insights into key Kubernetes objects that can be effectively used for deploying containerized applications. It then focuses on all major Kubernetes constructs, offering guidance on their appropriate utilization in different scenarios, while emphasizing the significance of a Zero Trust architecture. Additionally, the book addresses important aspects such as service discovery, optimized logging, and monitoring, which play a critical role in managing distributed applications. It also incorporates essential concepts from Site Reliability Engineering and enabling engineering teams, to proactively meeting Service Level Agreements and attaining operational readiness. In the final section, the book takes a deep dive into Service Mesh, with a special focus on harnessing the strength of Istio as a powerful tool. By the end of the book, you will have the knowledge and skills to effectively build, deploy, and manage secure applications using Kubernetes and Istio. WHAT YOU WILL LEARN ● Learn how to successfully deploy applications on Kubernetes. ● Gain insights into the principles of Zero Trust architecture and its implementation within the Kubernetes orchestration platform. ● Get familiar with the concepts of service discovery and efficient scaling in Kubernetes, empowering you to optimize your application deployments. ● Learn about monitoring and logging within applications, and explore the essential aspects of observability to ensure the reliability of your systems. ● Acquire expertise in service mesh, particularly Istio, to efficiently handle traffic, enhance application reliability, and fortify security measures.
