Network Automation with Go

By: Nicolas Leiva, Michael Kashin

Overview of this book

Go’s built-in first-class concurrency mechanisms make it an ideal choice for long-lived low-bandwidth I/O operations, which are typical requirements of network automation and network operations applications. This book provides a quick overview of Go and hands-on examples within it to help you become proficient with Go for network automation. It’s a practical guide that will teach you how to automate common network operations and build systems using Go. The first part takes you through a general overview, use cases, strengths, and inherent weaknesses of Go to prepare you for a deeper dive into network automation, which is heavily reliant on understanding this programming language. You’ll explore the common network automation areas and challenges, what language features you can use in each of those areas, and the common software tools and packages. To help deepen your understanding, you’ll also work through real-world network automation problems and apply hands-on solutions to them. By the end of this book, you’ll be well-versed with Go and have a solid grasp on network automation.

Developing distributed applications

Building a distributed application, such as bgp-ping, can be a major undertaking. Unit testing and debugging can help spot and fix a lot of bugs, but these processes can be time-consuming. In certain cases, when an application has different components, developing your code iteratively may require some manual orchestration. Steps such as building binary files and container images, starting the software process, enabling logging, and triggering events are now something you need to synchronize and repeat for all the components that include your application.

The final developer experience tool that we will cover in this chapter was specifically designed to address the preceding issues. Tilt helps developers automate manual steps, and it has native integration with container and orchestration platforms, such as Kubernetes or Docker Compose. You let it know which files to monitor, and it will automatically rebuild your binaries, swap out container...
