This manual consists of instructions to set up integrated Internet services using existing free software for you, your family and/or your organization under a framework using Docker. Before reading this manual, make sure you understand the basics of GNU/Linux commands (or a different POSIX system such as Mac OS X, FreeBSD). Server setup knowledge is recommended but not required. By following the instructions in this manual, you should be able to set up an integrated system running multiple server software---we will refer them as "Internet apps" throughout this manual. In addition, you can also use this manual as a reference. For instance, if you follow some other instructions to deploy a server with Docker, or to set up some of the software mentioned in this manual, this manual may be helpful.

Create generic pipelines to reduce your overall DevOps workload and allow your team to deliver faster. This book helps you get up to speed on the pros and cons of generic pipeline methodology, and learn to combine shell scripts and Docker to build generic pipelines. In today’s world of micro-services and agile practices, DevOps teams need to move as fast as feature teams. This can be extremely challenging if you’re creating multiple pipelines per application or tech stack. What if your feature teams could utilize a generic pipeline that could build, test, and deploy any application, regardless of tech stack? What if that pipeline was also cloud and platform agnostic? Too good to be true? Well think again! Generic Pipelines Using Docker explores the principles and implementations that allow you to do just that. You will learn from real-world examples and reusable code. After reading this book you will have the knowledge to build generic pipelines that any team can use. What You'll Learn Explore the pros and cons of generic pipeline methodology Combine shell scripts and Docker to build a generic pipeline Implement a pipeline across CI/CD platforms Build a pipeline that lends itself well to both centralized and federated DevOps teams Construct a modular pipeline with components that can be added, removed, or replaced as needed Who This Book Is For Professionals who use DevOps or are part of a DevOps team, and are seeking ways to streamline their pipelines and drive more deployments while using less code

A Case Study in Enabling DevOps Using Docker

There are varying definitions for DevOps, but at its core, it is a software engineering methodology. The concept of DevOps was born from the need to create synergy between the people who develop software (Dev), and the operations people who manage production systems (Ops). The result is a methodology that strives to create a streamlined approach to the full lifecycle of software-from development to production support and maintenance. DevOps methodologies do so by implementing automation that enables a repeatable process for building, testing, deploying and managing software components. Docker is a platform that allows for the packaging of these software components, as well as any dependencies, into isolated virtual containers. These Docker containers are portable across any Linux based infrastructure that has Docker installed. DevOps processes that are supported with Docker enable developers to produce self- contained applications that are delivered in a fast, repeatable way. Docker is relatively new within the technology community and is gaining wide support. In this report I evaluate features available within Docker. I also implement and describe a system to build and deploy Docker containers. These containers could be used for deployment to any Linux based server or public cloud offering that supports Docker. Finally, I identify issues that would need to be considered when using Docker, as well as provide topics for future work.
