Turnbull Press
Free sample

A hands-on introduction to Packer, the HashiCorp image builder. Packer helps engineers, developers, sysadmins, and operations staff build multi-platform images including support for Docker containers, virtual machines, and Cloud-based images for platforms like Amazon Web Services and Google Cloud. Packer allows you to build consistent images on Linux, Microsoft Windows, macOS and other operating systems. In the book, we'll teach you how to install, use and integrate Packer into your environment and work flow. The book includes chapters on:

* Installing Packer.

* Building images.

* Provisioning images.

* Integration with Configuration Management tools like Ansible, Chef and Puppet.

* Packer and Docker containers.

* Integrating and writing infrastructure tests.

* Building pipelines for Continuous Integration with Packer.

* Extending Packer.

This is a practical guide for software developers, and different than other software architecture books. Here's why:

It teaches risk-driven architecting. There is no need for meticulous designs when risks are small, nor any excuse for sloppy designs when risks threaten your success. This book describes a way to do just enough architecture. It avoids the one-size-fits-all process tar pit with advice on how to tune your design effort based on the risks you face.

It democratizes architecture. This book seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties.

It cultivates declarative knowledge. There is a difference between being able to hit a ball and knowing why you are able to hit it, what psychologists refer to as procedural knowledge versus declarative knowledge. This book will make you more aware of what you have been doing and provide names for the concepts.

It emphasizes the engineering. This book focuses on the technical parts of software development and what developers do to ensure the system works not job titles or processes. It shows you how to build models and analyze architectures so that you can make principled design tradeoffs. It describes the techniques software designers use to reason about medium to large sized problems and points out where you can learn specialized techniques in more detail.

It provides practical advice. Software design decisions influence the architecture and vice versa. The approach in this book embraces drill-down/pop-up behavior by describing models that have various levels of abstraction, from architecture to data structure design.
