Serious About Learning Linux? Get 15 O’Reilly Linux and DevOps eBooks for Under $25

Linux is the invisible engine behind the modern internet. From cloud servers and containerized applications to CI/CD pipelines and network automation, it powers the systems that keep the world connected. For system administrators and DevOps engineers, staying ahead means constantly sharpening a broad and evolving skill set. If you’re looking to bridge gaps or build expertise from the ground up, there’s a new opportunity that’s hard to ignore.

Humble Bundle has launched a comprehensive collection of DevOps-focused eBooks from O’Reilly, covering everything from Linux administration and automation to security, containers, and cloud infrastructure. And here’s the kicker: a portion of every purchase supports Code for America, a nonprofit using technology to improve government services for those who need them most.

⏲️ The deal ends on February 28, 2026 — so time is ticking.

So, What’s in The Bundle?

The collection features 15 expertly curated titles, each tackling a critical area of modern IT operations. Let’s break it down.

Linux administration is covered from multiple angles. Efficient Linux at the Command Line focuses on boosting productivity at the shell — the kind of mastery that pays dividends every single day. Learning Modern Linux takes a broader view, diving into file permissions, application dependency management, and networking as they’re used in the real world. Practical Linux System Administration covers the operational nuts and bolts: managing users, storage, SELinux, networking, and services on live systems. And the Linux Pocket Guide serves as a quick-reference companion for common commands and tasks.

On the DevOps and automation front, Python for DevOps explores scripting, automation, and working with infrastructure APIs — a core competency in today’s DevOps roles. Ansible: Up and Running, now in its third edition, is one of the best introductions to configuration management and automation with Ansible. Learning GitHub Actions dives into CI/CD workflows using GitHub’s built-in automation platform.

For infrastructure as code, Terraform: Up and Running is widely regarded as the definitive guide to provisioning cloud infrastructure. The third edition covers modern Terraform practices, including modules, state management, and multi-provider workflows.

The containers and orchestration section is equally robust. Docker: Up & Running covers building and running containers from the ground up. Kubernetes: Up and Running, now in its third edition, handles orchestration with deep dives into workloads, networking, and cluster management.

Security gets two dedicated titles. Learning DevSecOps focuses on integrating security practices directly into the development and deployment pipeline — not as an afterthought, but as a foundational discipline. Web Application Security covers offensive and defensive techniques for securing web applications, with the second edition split into three comprehensive parts.

Rounding out the bundle, Network Programmability and Automation is aimed at network engineers looking to apply DevOps principles to network infrastructure using Python and tools like Ansible. FastAPI covers building APIs with the increasingly popular Python FastAPI framework, ideal for backend and microservices work. And Learning Git offers a rock-solid foundation in version control, covering branching, merging, rebasing, and remote repository workflows.
