Good!! If you're reading this now, it's not a Coincidence. You're interested in Learning about Docker and How it Works!! Docker is Software that enables Container Virtualization of applications. Applications, including their dependencies, can be packed into an image. Using a unique engine, the packaged application can then be executed in a Docker Container. Except for some Interfaces to Operating Systems or Hardware, the application is completely isolated. Any number of containers can be created from an image and operated in parallel, for example, scalable Cloud Services. Container Virtualization comes in many variants; Docker tries to make working with Containers as practical and uncomplicated as possible. As a Developer, for example, you can isolate your subproject into a container and transfer it to the test server with Docker Engine. There you can do the required tests without lengthy Installation or waiting for the next build.With Docker Container, the Project can also be quickly and easily shared with colleagues or, more generally, independently of the client. Also, because the Containers are isolated, it is possible to simulate different environments for Software. In this Book, we are coming up with an Introduction and Technical information about Docker. Everything is well explained in layman terms to help Beginners learn, understand, and Master Docker very fast. Other things you will learn in this Book include: What is Docker? Understand containers first Why you need Docker? Is it useful to use Docker containers in programming? Important features to know about Docker Easy pack, ship, and run of the application Storing single codes in containers Getting Started with Docker Orientation and Setup The Docker file Docker for various operating systems Dockers for Windows Accessing Setting dialog Kubernetes Dockers for Linux Installation Docker Troubleshooting Common mistakes with Dockerfiles Use of ADD instead of COPY Entering whole application directory in a line Running multiple services in one container Improper usage of Docker's builds cache Storing data in containers What to avoid while using Dockers Running "apt-get install."

Become an expert in the innovative containerization tool to unlock new opportunities in the way you use and deploy software About This Book Harness the power of Docker to create a robust and resilient environment in which you can generate portable, composable, scalable, and stable application containers Learn the art of container networking with elevated efficiency using Docker Better manage Docker containers using expert techniques and methods Explore the ways to keep your Docker environment secure Deploy your applications easily Who This Book Is For Whether you are a developer or a sysadmin, or anything in between, this course will give you the guidance you need to use Docker to build, test, and deploy your applications and make them easier, even enjoyable. What You Will Learn Learn how to install Docker across all the platforms along with a few troubleshooting techniques Build, push, and publish images on Docker Hub Orchestrate multiple containers with Docker Compose Test and debug applications inside a Docker container Get to know the basics of networking and see how Docker networking works Discover the tools built into Docker to gain an insight into your container's performance Take advantage of the various SaaS offerings from third parties to move monitoring away from your local infrastructure and into the cloud Familiarize yourself with third-party tools such as Traffic Authorization, Summon, sVirt, and SELinux to secure your Docker environment Integrate Docker with a wide range of cloud and configuration tools to fully realize its potential In Detail So hot off the presses, the latest buzz that has been on the tip of everyone's tongues and the topic of almost any conversation that includes containers these days is Docker! Docker has been a game-changer when it comes to virtualization. With this course, you will go from just being the person in the office who hears that buzz to the one who is tooting it around every day. This course will be a smooth journey covering Docker from scratch to finish! The first module will help you get familiarized with the fundamentals of Docker. The second module will show you how to create, deploy, and manage a virtual network for connecting containers spanning single or multiple hosts. In the third module, you'll get to grips with monitoring your Docker apps and containers - this will show you how monitoring containers and keeping a keen eye on the working of applications helps improve the overall performance of the applications that run on Docker. The purpose of our fourth module, Securing Docker, is to provide techniques and enhance your skills to secure Docker containers easily and efficiently. Finally, you'll see how to deploy Docker in production and three interesting GUI applications: Shipyard, Panamax, and Tutum. Style and approach Covering best practices to make sure you're confident with the basics, such as building, managing, and storing containers, before diving deeper into Docker security, you'll find everything you need to help you extend and integrate Docker in new and innovative ways.

A concise, fast-paced guide to orchestrating and deploying scalable services with Docker About This Book Explore the new features added to the core Docker Engine to make multi-container orchestration easy Leverage tools such as Docker Machine, Swarm, Compose, and third-party tools such as Kubernetes, Mesosphere, and CoreOS to orchestrate containers Use Docker Compose with Swarm and apply rolling updates for zero downtime deployments Who This Book Is For This book is aimed at Sysadmins and DevOps engineers who know what Docker does and are now looking to manage multiple containers on multiple hosts using the orchestration feature. What You Will Learn Build scalable, reliable services with Docker See how to manage a service in Docker using Docker Swarm, Kubernetes, and Mesosphere Discover simpler orchestration tools such as CoreOS/Fleet and Rancher Cattle Understand cluster-wide logging, system monitoring, and troubleshooting Build, test, and deploy containers using Continuous Integration Deploy cluster hosts on cloud services and automate your infrastructure In Detail Docker orchestration is what you need when transitioning from deploying containers individually on a single host to deploying complex multi-container apps on many machines. This book covers the new orchestration features of Docker 1.12 and helps you efficiently build, test, and deploy your application using Docker. You will be shown how to build multi-container applications using Docker Compose. You will also be introduced to the building blocks for multi-host Docker clusters such as registry, overlay networks, and shared storage using practical examples. This book gives an overview of core tools such as Docker Machine, Swarm, and Compose which will enhance your orchestration skills. You'll learn how to set up a swarm using the decentralized building block. Next, you'll be shown how to make the most out of the in-built orchestration feature of Docker engine and you'll use third-party tools such as Kubernetes, Mesosphere, and CoreOS to orchestrate your existing process. Finally, you will learn to deploy cluster hosts on cloud services and automate your infrastructure.
