Overview of this book

Go is the go-to language for DevOps libraries and services, and without it, achieving fast and safe automation is a challenge. With the help of Go for DevOps, you'll learn how to deliver services with ease and safety, becoming a better DevOps engineer in the process. Some of the key things this book will teach you are how to write Go software to automate configuration management, update remote machines, author custom automation in GitHub Actions, and interact with Kubernetes. As you advance through the chapters, you'll explore how to automate the cloud using software development kits (SDKs), extend HashiCorp's Terraform and Packer using Go, develop your own DevOps services with gRPC and REST, design system agents, and build robust workflow systems. By the end of this Go for DevOps book, you'll understand how to apply development principles to automate operations and provide operational insights using Go, which will allow you to react quickly to resolve system failures before your customers realize something has gone wrong.

Summary

In Chapter 9, Observability with OpenTelemetry, we explored how using Open Telemetry can provide observability into your application and the applications it depends on. We discussed how to set up telemetry for your application using the two most popular backends: Jaeger and Prometheus, which are both written in Go. In Chapter 10, Automating Workflows with GitHub Actions, we showed how you can use GitHub actions to automate your code deployments and how to add custom actions using Go. Finally, in this chapter, we looked at the architecture for interacting with a service. We built an interaction layer using Slack to do operations such as filtering traces, getting the currently deployed version, and showing alerts.

In the next set of chapters, we will talk about how to use Go, and tools written in Go, to ease the burden of working in the cloud. This will cover building standard images that can be deployed to VMs or other node infrastructure. We will show how you can extend...
