Kubernetes: Up and Running

The race to compete in today's fast-moving markets, large enterprises are busy adopting new technologies for creating new products, processes, and business models. But one obstacle on the road to digital transformation is placing too much emphasis on technology, and not enough on the types of processes technology enables. What if different lines of business could build their own services and applications-and decision-making was distributed rather than centralized? This report explores the concept of a digital business platform as a way of empowering individual business sectors to act on data in real time. Much innovation in a digital enterprise will increasingly happen at the edge, whether it involves business users (from marketers to data scientists) or IoT devices. To facilitate the process, your core IT team can provide these sectors with the digital tools they need to innovate quickly

Based on the experiences of companies that are running Kubernetes in production successfully, many of the methods are also backed by concrete code examples. This book is ideal for those already familiar with basic Kubernetes concepts who want to learn common best practices. You’ll learn exactly what you need to know to build your best app with Kubernetes the first time. Set up and develop applications in Kubernetes Learn patterns for monitoring, securing your systems, and managing upgrades, rollouts, and rollbacks Understand Kubernetes networking policies and where service mesh fits in Integrate services and legacy applications and develop higher-level platforms on top of Kubernetes Run machine learning workloads in Kubernetes

Es heißt, dass Google über zwei Milliarden Anwendungscontainer pro Woche deployt. Wie ist das möglich? Diese Frage hat Google mit einem Projekt namens Kubernetes beantwortet, einem Cluster-Orchestrierer, der das Bauen, Deployen und Warten skalierbarer, verteilter Systeme in der Cloud radikal vereinfacht. Dieser praktische Leitfaden zeigt Ihnen, wie Kubernetes und die Container-Technologie Ihnen helfen können, in Bezug auf Schnelligkeit, Agilität, Zuverlässigkeit und Effizienz in ganz neue Bereiche vorzudringen. Die Autoren Kelsey Hightower, Brendan Burns und Joe Beda haben bei Google und in anderen Firmen mit Kubernetes gearbeitet und erklären Ihnen, wie sich dieses System in den Lebenszyklus einer verteilten Anwendung einfügt. Sie werden lernen, wie Sie Tools und APIs einsetzen, um skalierbare, verteilte Systeme zu automatisieren – egal ob es sich um Online-Services, Systeme zum maschinellen Lernen oder ein Cluster aus Raspberry Pis handelt. Lernen Sie die Herausforderungen verteilter Systeme kennen, die Sie mit Kubernetes angehen können. Tauchen Sie ein in die containerisierte Anwendungsentwicklung und nutzen Sie dabei zum Beispiel Docker-Container. Erstellen Sie Container im Docker-Image-Format mit Kubernetes und lassen Sie sie über die Docker-Runtime ausführen. Begutachten Sie die zentralen Konzepte und API-Objekte von Kubernetes, die notwendig sind, um Anwendungen produktiv laufen zu lassen. Rollen Sie neue Softwareversionen zuverlässig ohne Downtime oder Fehler aus. Lernen Sie aus Beispielen zum Entwickeln und Deployen realer Anwendungen in Kubernetes.

Certified Kubernetes Administrator (CKA) Exam Guide

Legend has it that Google deploys over two billion application containers a week. How’s that possible? Google revealed the secret through a project called Kubernetes, an open source cluster orchestrator (based on its internal Borg system) that radically simplifies the task of building, deploying, and maintaining scalable distributed systems in the cloud. This practical guide shows you how Kubernetes and container technology can help you achieve new levels of velocity, agility, reliability, and efficiency. Authors Kelsey Hightower, Brendan Burns, and Joe Beda—who’ve worked on Kubernetes at Google and other organizatons—explain how this system fits into the lifecycle of a distributed application. You will learn how to use tools and APIs to automate scalable distributed systems, whether it is for online services, machine-learning applications, or a cluster of Raspberry Pi computers. Explore the distributed system challenges that Kubernetes addresses Dive into containerized application development, using containers such as Docker Create and run containers on Kubernetes, using the docker image format and container runtime Explore specialized objects essential for running applications in production Reliably roll out new software versions without downtime or errors Get examples of how to develop and deploy real-world applications in Kubernetes

While Kubernetes has greatly simplified the task of deploying containerized applications, managing this orchestration framework on a daily basis can still be a complex undertaking. With this practical book, site reliability and DevOps engineers will learn how to build, operate, manage, and upgrade a Kubernetes cluster—whether it resides on cloud infrastructure or on-premises. Brendan Burns, cofounder of Kubernetes, and Craig Tracey, staff field engineer at Heptio, dissect how Kubernetes works internally and demonstrate ways to maintain, adjust, and improve the cluster to suit your particular use case. You’ll learn how to make architectural choices for designing a cluster, managing access control, monitoring and alerting, and upgrading Kubernetes. Dive in and discover how to take full advantage of this orchestration framework’s capabilities. Learn how your cluster operates, how developers use it to deploy applications, and how Kubernetes can facilitate a developer’s job Adjust, secure, and tune your cluster by understanding Kubernetes APIs and configuration options Detect cluster-level problems early and learn the steps necessary to respond and recover quickly Determine how and when to add libraries, tools, and platforms that build on, extend, or otherwise improve a Kubernetes cluster

Managing Kubernetes

Container und Container-Orchestrierer haben die Entwicklung verteilter Systeme grundlegend verändert – es gibt jetzt Objekte und Schnittstellen für das Darstellen zentraler Muster für verteilte Systeme und das Bauen wiederverwendbarer, containerisierter Komponenten. Dieser praktische Ratgeber stellt Ihnen eine Reihe immer wieder einsetzbarer, generischer Muster vor, mit denen die Entwicklung zuverlässiger verteilter Systeme einfacher und effizienter geschehen kann. Bisher mussten Entwickler diese Systeme von Grund auf selbst bauen, daher ist jede Systemarchitektur einmalig. Brendan Burns, Director of Engineering bei Microsoft Azure, zeigt Ihnen in diesem Buch, wie Sie vorhandene Software-Entwurfsmuster adaptieren können, um zuverlässige verteilte Anwendungen zu bauen. System- und Anwendungsentwickler erfahren hier, wie diese Muster eine gemeinsame Sprache und ein Framework schaffen, die die Qualität dieser Systeme deutlich verbessern. In diesem Buch: Verstehen Sie, wie Muster und wiederverwendbare Komponenten die schnelle Entwicklung zuverlässiger verteilter Systeme ermöglichen. Nutzen Sie die Sidecar-, Adapter-und Ambassador-Muster, um Ihre Anwendung in eine Gruppe von Containern auf einer einzelnen Maschine zu unterteilen. Verwenden Sie lose gekoppelte verteilte Multi-Node-Muster zur Replikation, zum Skalieren und für die Kommunikation zwischen den Komponenten. Lernen Sie Muster für die Batch-Verarbeitung von Massendaten kennen, die sich um Work Queues, ereignisbasierte Verarbeitung und koordinierte Workflows drehen. Brendan Burns ist angesehener Entwickler in Microsoft Azure und Mitbegründer des Open-Source-Projekts Kubernetes. Bevor er zu Microsoft kam, arbeitete er bei Google an der Google Cloud Platform und half dabei, APIs wie den Deployment Manager und die Cloud DNS zu bauen.
