[](https://itsfoss.com/content/images/2025/11/linux-for-professionals-bundle.jpeg) ![a cropped screenshot of the o'reilly linux for seasoned admins bundle on humble bundle's website, a lot of text and three books from the bundle are shown here](https://itsfoss.com/content/images/2026/02/oreilly-linux-for-seasoned-admins.png) The 15 books here span a good range of topics. Here's a breakdown of what's included. **Linux administration** is covered from a few different angles. **Efficient Linux at the Command Line** focuses on boosting productivity at the shell, which is the kind of thing that pays off every single day. **Learning Modern Linux** takes a broader look at Linux as it's actually used today, including file permissions, application dependency management, and networking. **Practical Linux System Administration** covers the operational side of managing users, storage, setting up [SELinux](https://www.redhat.com/en/topics/linux/what-is-selinux?ref=itsfoss.com), networking, and services on live systems. ![Humble Bundle Linux eBooks](https://itsfoss.com/content/images/2026/02/humble-bundle-1.webp) The **Linux Pocket Guide** rounds it out as a handy reference for common commands and tasks. On the **DevOps and automation** side, **Python for DevOps** covers using [Python](https://www.python.org/?ref=itsfoss.com) for scripting, automation, and working with infrastructure APIs, which has become a core skill in most DevOps roles. **Ansible: Up and Running** is one of the better introductions to configuration management and automation with [Ansible](https://github.com/ansible/ansible?ref=itsfoss.com), now in its third edition. **Learning GitHub Actions** gets into CI/CD workflows using GitHub's built-in automation platform. For **infrastructure as code**, **Terraform: Up and Running** is widely considered one of the go-to books on provisioning cloud infrastructure. The third edition covers current [Terraform](https://developer.hashicorp.com/terraform?ref=itsfoss.com) practices, including modules, state management, and working across multiple providers. ![Humble Bundle Linux ebooks](https://itsfoss.com/content/images/2026/02/humble-bundle-2.webp) The **containers and orchestration** section is well represented. **Docker: Up & Running** covers building and running containers from the ground up. **Kubernetes: Up and Running** handles orchestration, now in its third edition, with content on workloads, networking, and cluster management. **Security** gets two dedicated titles. **Learning DevSecOps** focuses on integrating security practices into the development and deployment pipeline rather than treating it as an afterthought. **Web Application Security** covers offensive and defensive techniques for securing web applications, with the second edition splitting the curriculum into three 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 Python [FastAPI](https://fastapi.tiangolo.com/?ref=itsfoss.com) framework, increasingly popular in backend and microservices work. And **Learning Git** is a solid foundation for version control, covering branching, merging, rebasing, and working with remote repositories. ### What Do You Get for Your Money? All 15 books are available in PDF and ePub formats, compatible with computers, smartphones, tablets, and most e-readers. **Here's the complete collection.** 👇 | Column 1 | Column 2 | | ------------------------------------ | ------------------------------------------------ | | Python for DevOps | Practical Linux System Administration | | Efficient Linux at the Command Line | Ansible: Up and Running (3rd Ed.) | | Learning DevSecOps | Docker: Up & Running (3rd Ed.) | | Web Application Security (2nd Ed.) | Linux Pocket Guide (4th Ed.) | | Terraform: Up and Running (3rd Ed.) | FastAPI | | Learning Modern Linux | Network Programmability and Automation (2nd Ed.) | | Kubernetes: Up and Running (3rd Ed.) | Learning Git | | Learning GitHub Actions | | This bundle has **a starting price of $21.80 for all 15 books**.
