Mastering Go for DevOps

Build cloud native apps, Terraform providers, and scalable DevOps tools using Go in production grade systems

Key Features

• Build scalable DevOps tools, APIs, and CLIs using Go
• Develop custom Terraform providers and test them with the SDK
• Integrate Prometheus metrics, AWS, and Azure cloud SDKs

Book Description

Go is a modern programming language known for its simplicity, performance, and scalability, making it ideal for building DevOps tooling and infrastructure solutions. This book shows you how to harness Go to build production-ready tools, from interactive CLIs to observability integrations and custom Terraform providers.

Mastering Go for DevOps takes a hands-on approach, teaching you how to create robust CLI applications, develop RESTful APIs and gRPC services, and integrate monitoring solutions with Prometheus. You’ll extend Terraform with custom providers, write comprehensive unit and integration tests using the Terraform SDK, and automate your testing in CI/CD pipelines with GitHub Actions.

You’ll also explore cloud-native development by integrating Go applications with AWS and Azure SDKs and deploying serverless functions with AWS Lambda and Azure Functions. Whether you’re building automation scripts or distributed systems, this book equips you with the skills to streamline and scale your infrastructure operations.

By the end of this book, you’ll know how to build Go-based DevOps tools, automate infrastructure provisioning, and create cloud-native systems ready for real-world deployment.
