Overview

Stop Patching Servers. Start Engineering Platforms Are you tired of configuration drift, endless security patches, and the anxiety of upgrading your Kubernetes nodes? For decades, we have treated our servers like pets, nursing them with SSH, shell scripts, and manual intervention. We built modern cloud-native applications on top of an operating system designed in the 1990s. The result? Fragile infrastructure, security vulnerabilities, and operational toil. It is time to delete your SSH keys. Talos Linux for DevOps is the definitive guide to mastering the first operating system designed exclusively for Kubernetes. Written for Site Reliability Engineers, Platform Engineers, and CTOs, this book takes you from the first boot to advanced disaster recovery, teaching you how to build infrastructure that is immutable, secure, and API-driven by default. Inside, you will discover how to: Eliminate the ""General-Purpose Tax"" Stop wasting resources and security surface area on an OS that thinks it's a desktop. Learn why removing the shell, SSH, and local users makes your cluster exponentially more secure. Master Atomic Upgrades: Say goodbye to apt-get update. Learn how Talos uses A/B partitioning to perform risk-free, atomic OS upgrades that can roll back automatically if they fail. Manage the OS via API: Discover talosctl and machined, and learn how to manage your operating system with the same precision as your Kubernetes workloads-using structured data, not text files. Implement True GitOps: Extend your GitOps workflow below the Kubernetes layer. Learn how to manage your kernel parameters, network interfaces, and disk encryption declaratively using Flux or Argo CD. Architect High Availability: Build production-ready control planes, configure Virtual IPs (VIPs) for failover, and understand the mathematics of Etcd quorum to prevent downtime. Execute Disaster Recovery: Go beyond backups. Learn the exact workflows to recover a lost control plane, restore Etcd from snapshots, and ""nuke and pave"" corrupted nodes with confidence. Who is this book for? This book is for the DevOps engineer who is ready to stop fighting the operating system. Whether you are running on bare metal, AWS, or at the edge, Talos Linux for DevOps provides the architectural blueprints and hands-on commands you need to build a platform that is boring, predictable, and unbreakable. Transform your infrastructure into an immutable engine of reliability.
