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.

Antonio Ojea is a Software Engineer at Red Hat, where he works on Kubernetes and other open source projects, mainly focused on cloud technologies, networking, and containers. He is currently a maintainer and contributor on the Kubernetes and KIND projects and has contributed in the past to other projects such as OpenStack and MidoNet.

During my early years as a professional, I started in the network department of a telecommunications company. We were responsible for the internal network and its services (DNS, email, WWW, and so on). At that time, our automation consisted basically of the following:

  • Configuration: TCL/Expect scripts that connected to the network devices to apply different configurations
  • Monitoring: Perl scripts that polled via SNMP the network devices and stored the data on Round Robin Database (RRD) files
  • Logging: Using a central Syslog server dumping all logs to text files that were rotated periodically via cron
  • Alerting and reporting...
