Learn Helm

Get up to speed with Helm, the preeminent package manager for the Kubernetes container orchestration system. This practical guide shows you how to efficiently create, install, and manage the applications running inside your containers. Helm maintainers Matt Butcher, Matt Farina, and Josh Dolitsky explain how this package manager fits into the Kubernetes ecosystem and provide an inside look at Helm's design and best practices. More than 70% of the organizations that work with Kubernetes use Helm today. While the Helm community provides thousands of packages, or charts, to help you get started, this book walks developers and DevOps engineers through the process of creating custom charts to package applications. If you have a working understanding of Kubernetes, you're ready to go. Explore primary features including frequently used Helm commands Learn how to build and deploy Helm charts from scratch Use Helm to manage complexity and achieve repeatable deployments Package an application and its dependencies for easy installation Manage the entire lifecycle of applications on Kubernetes Explore ways to extend Helm to add features and functionality Learn features for testing, handling dependencies, and providing security

A comprehensive introduction to automated application deployment on Kubernetes for beginners Key FeaturesEffectively manage applications deployed in Kubernetes using HelmLearn to install, upgrade, share, and manage applications deployed in KubernetesGet up and running with a package manager for KubernetesBook Description Containerization is currently known to be one of the best ways to implement DevOps. While Docker introduced containers and changed the DevOps era, Google developed an extensive container orchestration system, Kubernetes, which is now considered the frontrunner in container orchestration. With the help of this book, you’ll explore the efficiency of managing applications running on Kubernetes using Helm. Starting with a short introduction to Helm and how it can benefit the entire container environment, you’ll then delve into the architectural aspects, in addition to learning about Helm charts and its use cases. You’ll understand how to write Helm charts in order to automate application deployment on Kubernetes. Focused on providing enterprise-ready patterns relating to Helm and automation, the book covers best practices for application development, delivery, and lifecycle management with Helm. By the end of this Kubernetes book, you will have learned how to leverage Helm to develop an enterprise pattern for application delivery. What you will learnDevelop an enterprise automation strategy on Kubernetes using HelmCreate easily consumable and configurable Helm chartsUse Helm in orchestration tooling and Kubernetes operatorsExplore best practices for application delivery and life cycle managementLeverage Helm in a secure and stable manner that is fit for your enterpriseDiscover the ins and outs of automation with HelmWho this book is for This book is for Kubernetes developers or administrators who are interested in learning Helm to provide automation for application development on Kubernetes. Although no prior knowledge of Helm is required, basic knowledge of Kubernetes application development will be useful.

Completely updated, this popular guide provides teachers with a proven method for documenting (collecting, analyzing, and displaying) young children’s work. Written by teachers for teachers, it also shows principals, curriculum coordinators, and directors of early intervention programs how to develop children’s portfolios to share with parents or to use for assessment and other accountability purposes. “This lively, informative book poses a remarkable challenge to teachers—to grow themselves while growing young children. Being creatively accountable is hard work and the stories told here describe both the work, how it’s done, and its joyful rewards for teachers and children.” —Elizabeth Jones, Pacific Oaks College “This book provides a set of windows on children’s lives and how teachers can enter into those lives and enrich them through high-quality teaching. The authors have created an inspiring volume, a challenging set of ideas, and an invaluable resource for early childhood educators.” —Samuel J. Meisels, University of Michigan “[A] thoughtful, up-to-date guide to assessing and documenting children’s work. . . . The authors give clear, practical advice on how to collect, analyze, and display children’s work in meaningful ways.” —Scholastic Early Childhood Today (on first edition) “Many teachers find it frustrating to hear the rich and exciting learning experiences they provide described as ‘nothing.’ Windows on Learning skillfully addresses the challenge faced by early childhood educators wishing to share classroom experiences with parents, administrators, and peers. The authors offer a timely and fresh approach to documenting children’s learning and work.” —Childhood Education (on first edition)

Renewable energy and sustainable development have become more prominent in the world, providing capitalistic opportunities for shrewd businessmen and corporate wars. When an opportunity to provide a renewable electricity source for a new city in Saudi Arabia is released for tender, billionaire entrepreneur and investment savant, Jim Dunsmuir, begins building a revolutionary idea he believes will change the face of the world’s power and travel systems. His competition is ex-oil magnate, George Anderson, the founder of one of the largest solar companies in the world. Now he is out to win the contract for his solar power company at all costs, even if it means pushing the boundaries of the law. Stuck in the middle of his dark mission is former NYPD detective Richard Emerson and his team at Trade Link Security. George has a way of making Richard feel like their periodic forays into the grey area of the law are inevitable and acceptable, despite Richard’s misgivings. As a high stakes battle begins, now only time will tell which entrepreneur will land the contract and which one will be sent down a path he never expected. In this thrilling tale, two successful entrepreneurs embark on separate journeys to make their mark in the ever-changing world of sustainable development and renewable energy.

He argues that the reasonableness of faith depends not only on beliefs about the world but also on beliefs about oneself (for instance about what one wants, about one's hopes and fears) and on what one is willing to trust. Helm goes on to look at the relations between belief and trust, and between faith and virtue, and concludes with an exploration of one particular type of belief about oneself, the belief that one is oneself a believer. This is a book for anyone interested in the basis of religious faith."--BOOK JACKET.
