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.
The Heroes in Training are entering the Underworld—if Hades can conquer his canine fears, that is. The Underworld usually isn’t really meant to be a fun place—but tell that to Hades! He loves the dark and the stinky smell of sulfur. However, there is one thing that Hades is not a fan of: dogs. And when Zeus and his fellow Olympians encounter Cerberus—a snarling, three-headed dog—Hades must conquer his fears and tame the hound so everyone can continue into the Underworld and deposit their Titan prisoner, Oceanus, back where he belongs! But with magical water that causes forgetfulness, hot beds of lava, and another epic battle with two more Titans standing in their way, will Zeus and his heroes make it out of the Underworld with everyone intact?
The authors developed an approach for thinking and communicating about documentation and then explored its use in early childhood programs, including the schools of Reggio Emilia. The result is a framework, collection system, and display method that works in U.S. schools. Methods are applicable to many different curriculum models, including thematic teaching and the project approach. Features extensive examples of children's and teachers' work.
The "project approach" has long been a tremendous tool for educators working with young children. This is not an activity book but a book about doing in-depth investigations about topics that interest your child and you. The project approach stimulates your child's curiosity, shows the advantages of learning academic skills such as reading, writing and math and helps you build a strong relationship with your child as you share the adventure of learning together. In this book, we have adapted the approach to show parents, grandparents and other caregivers how to do meaningful and exciting projects at home. Featuring many photos of children doing project work this book thoroughly explains the benefits to both you and your child of doing projects together. Ideas are given for transforming your home into a place to learn including guidance for collecting and storing materials, making time for projects, and documenting your child's work. Seven complete examples of at-home projects are shared. Chapters also show you how to coach your child to build skills for reading and writing, mathematical development, scientific thinking, and more. Direction is also provided for adapting the project approach for use in family child care centers, home schooling, and gifted education.
Randy Helm was raised on a ranch in Arizona. He went on to become a police officer, chaplain and pastor. In 2012 he was hired to develop and supervise the wild horse inmate program for Arizona State Prison. Randy developed a program to train convicted felons who had never touched a horse, to effectively gentle and train horses that had never been touched by a person. Getting the past behind you, The power of "one thing", Faith, Learning from failure and Overcoming abuse are just a few of the lessons in this book. The training program and the transformation in horses and inmates has been featured in local, national and international news and documentaries including ABC, NBC, Animal Planet and USA Today.

This bestseller provides an introduction to the project approach with step-by-step guidance for conducting meaningful investigations. The Third Edition has been expanded to include two new chaptersHow Projects Can Connect Children with Nature and Project Investigations as STEMand to assist teachers with younger children (toddlers) and older children (2nd grade).
Continuing the exploration of project work in the author’s bestselling book, Young Investigators, Second Edition, this book is designed for preschool through primary grade teachers who know how to do project work but are ready to move to the next level. Focusing on how children become young thinkers, the book begins with mind, brain, and education science and instructional guidelines for all learning experiences, and then connects these to the rich foundation of the project approach. Helm provides specific strategies for deepening project work, including how to select meaningful topics, plan for projects, integrate standards (including the Common Core), support children's questioning, create provocations to promote engagement, and help children represent their ideas. This practical resource will extend practitioners’ knowledge about project-based learning so they can move beyond the basics to create project work that is more engaging, meaningful, and productive. Book Features: Vivid examples of deep project work from real classrooms (pre–K through 2nd grade). An analysis worksheet for applications of Dewey's vision of child-centered learning. Charts for integrating CCSS for English Language Arts and Mathematics in kindergarten projects. A teacher reflection form for evaluating the depth of project work. “Throughout the book, examples and suggestions make clear the important distinctions between the deep investigations involved in project work versus the fairly common superficial theme activities too often seen in preschool and elementary school classes.” —From the Foreword by Lilian G. Katz, past president, National Association for the Education of Young Children (NAEYC) and professor emerita at the University of Illinois, Urbana–Champaign
