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.

Accessing SQL databases

DevOps engineers commonly have a need to access data stored in database systems. SQL is a standard for communicating with database systems that a DevOps engineer will encounter in their day-to-day lives.

Go provides a standard library for interacting with SQL-based systems called database/sql. The interfaces provided by that package, with the addition of a database driver, allow a user to work with several different SQL databases.

In this section, we will look at how we can access a Postgres database to perform basic SQL operations using Go.

Important Note

Examples in this section will require you to set up a Postgres database. This is beyond the scope of this book. This will not be a guide to SQL. Some basic SQL knowledge is required.

You can find information regarding how to install Postgres for your OS at https://www.postgresql.org/download/. If you prefer to run Postgres in a local Docker container, you can find that information at https:...
