With Red Hat Enterprise Linux 9 becoming the standard for enterprise Linux used from data centers to the cloud, Linux administration skills are in high demand. With this book, you’ll learn how to deploy, access, tweak, and improve enterprise services on any system on any cloud running Red Hat Enterprise Linux 9. Throughout the book, you’ll get to grips with essential tasks such as configuring and maintaining systems, including software installation, updates, and core services. You’ll also understand how to configure the local storage using partitions and logical volumes, as well as assign and deduplicate storage. You’ll learn how to deploy systems while also making them secure and reliable. This book provides a base for users who plan to become full-time Linux system administrators by presenting key command-line concepts and enterprise-level tools, along with essential tools for handling files, directories, command-line environments, and documentation for creating simple shell scripts or running commands. With the help of command line examples and practical tips, you’ll learn by doing and save yourself a lot of time.

Summary

In this chapter, we reviewed the basics of how to run, build, and share containers on RHEL 9. With this, you are prepared to create containers, run them, manage them, and even use systemd to ensure they’re always running in a production environment.

You are now ready to leverage the functionality and ease of deployment that containers provide. While a deep dive into all of the intricacies of migrating software into containers is outside the scope of this book, containers simplify the packaging and delivery of applications ready to be executed with all of their dependencies.

Containers are now a strong focus within the IT industry. Containers alone simplify how applications are packaged and delivered, but orchestration platforms such as OpenShift (based on Kubernetes) make it easier to deploy, upgrade, and manage containerized applications at scale.

Congratulations – you have made it to the end of this chapter! Now, it’s time to move on to the next...
