Most of the internet runs on Linux. From cloud servers and containerized apps to CI/CD pipelines and network automation, Linux is the backbone of modern infrastructure. And the people keeping all of it running, sysadmins and DevOps engineers, need a broad and constantly updated skill set to stay relevant.Keep in mind a portion of your purchase goes to support Code for America, a nonprofit that uses technology to improve government services for people who need them most.O’Reilly titles don’t come cheap individually, and the total retail value of this bundle is listed at 9, so getting all 15 for under is a pretty hefty discount. Head over to Humble Bundle (partner link) and grab the collection before the deal wraps up on February 28.Learning Modern Linux takes a broader look at Linux as it’s actually used today, including file permissions, application dependency management, and networking.

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.If you’ve been meaning to fill in some gaps or build up those skills from scratch, Humble Bundle has a new offering filled with DevOps-focused books from O’Reilly.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.The 15 books here span a good range of topics. Here’s a breakdown of what’s included.
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.Ansible: Up and Running is one of the better introductions to configuration management and automation with Ansible, now in its third edition. Learning GitHub Actions gets into CI/CD workflows using GitHub’s built-in automation platform.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.For infrastructure as code, Terraform: Up and Running is widely considered one of the go-to books on provisioning cloud infrastructure.
