Take container cluster management to the next level; learn how to administer and configure Kubernetes on CoreOS; and apply suitable management design patterns such as Configmaps, Autoscaling, elastic resource usage, and high availability. Some of the other features discussed are logging, scheduling, rolling updates, volumes, service types, and multiple cloud provider zones. The atomic unit of modular container service in Kubernetes is a Pod, which is a group of containers with a common filesystem and networking. The Kubernetes Pod abstraction enables design patterns for containerized applications similar to object-oriented design patterns. Containers provide some of the same benefits as software objects such as modularity or packaging, abstraction, and reuse. CoreOS Linux is used in the majority of the chapters and other platforms discussed are CentOS with OpenShift, Debian 8 (jessie) on AWS, and Debian 7 for Google Container Engine. CoreOS is the main focus becayse Docker is pre-installed on CoreOS out-of-the-box. CoreOS: Supports most cloud providers (including Amazon AWS EC2 and Google Cloud Platform) and virtualization platforms (such as VMWare and VirtualBox) Provides Cloud-Config for declaratively configuring for OS items such as network configuration (flannel), storage (etcd), and user accounts Provides a production-level infrastructure for containerized applications including automation, security, and scalability Leads the drive for container industry standards and founded appc Provides the most advanced container registry, Quay Docker was made available as open source in March 2013 and has become the most commonly used containerization platform. Kubernetes was open-sourced in June 2014 and has become the most widely used container cluster manager. The first stable version of CoreOS Linux was made available in July 2014 and since has become one of the most commonly used operating system for containers. What Youll Learn Use Kubernetes with Docker Create a Kubernetes cluster on CoreOS on AWS Apply cluster management design patterns Use multiple cloud provider zones Work with Kubernetes and tools like Ansible Discover the Kubernetes-based PaaS platform OpenShift Create a high availability website Build a high availability Kubernetes master cluster Use volumes, configmaps, services, autoscaling, and rolling updates Manage compute resources Configure logging and scheduling Who This Book Is For Linux admins, CoreOS admins, application developers, and container as a service (CAAS) developers. Some pre-requisite knowledge of Linux and Docker is required. Introductory knowledge of Kubernetes is required such as creating a cluster, creating a Pod, creating a service, and creating and scaling a replication controller. For introductory Docker and Kubernetes information, refer to Pro Docker (Apress) and Kubernetes Microservices with Docker (Apress). Some pre-requisite knowledge about using Amazon Web Services (AWS) EC2, CloudFormation, and VPC is also required. Deepak Vohra is an Oracle Certified Associate and a Sun Certified Java Programmer.

The 5th edition of this popular book has been fully updated for PHP 7, including replacing the PEAR package manager with Composer, and new material on Vagrant and PHP standards. It provides a solid grounding in PHPs support for objects, it builds on this foundation to instill core principles of software design and then covers the tools and practices needed to develop, test and deploy robust code. PHP Objects, Patterns, and Practice begins by covering PHPs object-oriented features. It introduces key topics including class declaration, inheritance, reflection and much more. The next section is devoted to design patterns. It explains the principles that make patterns powerful. The book covers many of the classic design patterns and includes chapters on enterprise and database patterns. The last segment of the book covers the tools and practices that can help turn great code into a successful project. The section shows how to manage multiple developers and releases with git, how to manage builds and dependencies with Composer. It also explores strategies for automated testing and continuous integration. Taken together these three elements: object fundamentals, design principles, and best practice will help the reader develop elegant and rock solid systems. PHP Objects, Patterns, and Practice: Describes and demonstrates PHPs built-in object-oriented features Breaks down the principles of object-oriented design, explaining key design patterns using practical examples. Discusses the tools and practices necessary for developing, testing and deploying exemplary applications. What Youll Learn: How to work with object fundamentals: writing classes and methods, instantiating objects, creating powerful class hierarchies using inheritance. Master advanced object-oriented features, including static methods and properties, managing error conditions with exceptions, and creating abstract classes and interfaces. Learn about the new object-oriented features introduced by PHP 7 and why they matter for your code. Understand and use design principles to deploy objects and classes effectively in your projects. Learn about design patterns, their purpose, structure and the underlying principles that govern them. Discover a set of powerful patterns that you can deploy in your own projects. Learn about the tools and practices that can guarantee a successful project including unit testing; version control, build, installation and package management; and continuous integration. Who This Book is For: This book is suitable for anyone with at least a basic knowledge of PHP who wants to use its object-oriented features in their projects. Those who already know their interfaces from their abstracts may well still find it hard to use these features in their systems. They will benefit from the books emphasis on design. They will learn how to choose and combine the participants of a system; how to read design patterns and how to use them in their code. Finally this book is for PHP coders who want to learn about the practices and tools (version control, testing, continuous integration, etc) that can make projects safe, elegant and stable.

This book also discusses the managed services for Docker Swarm: Docker for AWS and Docker Cloud Swarm mode. Docker Management Design Patterns explains how to use Docker Swarm mode with Docker Engine to create a distributed Docker container cluster and how to scale a cluster of containers, schedule containers on specific nodes, and mount a volume. This book is based on the latest version of Docker (17.0x). You will learn to provision a Swarm on production-ready AWS EC2 nodes, and to link Docker Cloud to Docker for AWS to provision a new Swarm or connect to an existing Swarm. Finally, you will learn to deploy a Docker Stack on Docker Swarm with Docker Compose. What Youll Learn Apply Docker management design patterns Use Docker Swarm mode and other new features Create and scale a Docker service Use mounts including volumes Configure scheduling, load balancing, high availability, logging and monitoring, rolling updates, resource management, and networking Use Docker for AWS managed services including a multi-zone Swarm Build Docker Cloud managed services in Swarm mode Who This Book Is For Docker admins, Docker application developers, and container as a service (CAAS) developers.

Become a Linux Ninja with Command Line Kung Fu! Do you think you have to lock yourself in a basement reading cryptic manual pages for months on end in order to have ninja like command line skills? In reality, if you had someone share their most powerful command line tips, tricks, and patterns you´d save yourself a lot of time and frustration. What if you could look over the shoulder of a good friend that just happened to be a command line guru? What if they not only showed you the commands they were using, but why they were using them and exactly how they worked? And what if that friend took the time to write all of it down so you can refer to it whenever you liked? Well, a friend did just that. Command Line Kung Fu is packed with dozens of tips and over 100 practical real-world examples. You won´t find theoretical examples in this book. The examples demonstrate how to solve actual problems and accomplish worthwhile goals. The tactics are easy to find, too. Each chapter covers a specific topic and groups related tips and examples together. For example, if you need help extracting text from a file look in the ´´Text Processing and Manipulation´´ chapter. Also, a comprehensive index is included. If you want to find every example where a given command is used - even if it´s not the main subject of the tip - look in the index. It will list every single place in the book where that command appears. Here is just some of what you will learn by reading Command Line Kung Fu: How to quickly and easily repeat commands in your shell history Shortcuts for grabbing specific words from your shell history to use in your current command How to save a copy of your command line session for later reference How to strip out blank lines and comments from files How to control colorized text when uses pipes and pagers Ways to transform text: from changing case to substituting characters and more ungekürzt.
