When building Docker images, the choice of the base image can significantly impact the final image size, performance, and security. Lightweight base images, such as Alpine Linux, have gained popularity in the Docker community for their minimal footprint and efficiency.
When it comes to system administration, managing processes and services is one of the most important skills. Processes are programs that run on your Ubuntu system, and services are background processes that typically start when your system boots and continue running to provide essential functions.
Let’s use a practical example to guide us through this process. By the end of this tutorial, you'll understand how to commit changes selectively, review modifications, and manage staged and unstaged changes.
Running Steam on a dual-GPU Linux machine can feel like herding pixels through quantum chaos. In this guide, we’ll untangle NVIDIA offload magic, identify which GPU is doing the work, and show how to make Steam—and your games—use the right one every time.
Armed with a few free days, a Steam sale, and a Linux server that definitely wasn’t built for gaming, I decided to relive Assassin’s Creed. This is the story of how three Ubisoft games, too many CPU cores, and a stubborn fullscreen mode turned into a surprisingly satisfying Linux gaming puzzle.
The key differences between Node.js and TypeScript. Learn how these technologies serve different purposes and complement each other for building scalable and reliable applications.
Integrating Docker into your Jenkins pipelines is a powerful way to create consistent and reproducible builds for your applications. By using Docker containers, you can ensure that your applications are built and tested in the same environment in which they will ultimately run.
As the demand for containerized applications continues to rise, the need for scalable, reliable, and cost-effective solutions has become a top priority for DevOps teams. Traditionally, deploying containers required provisioning and managing infrastructure, which could be time-consuming.
Docker security has become an essential consideration for organizations using containerization. Docker, by default, provides isolation between applications, but it’s still crucial to follow security best practices to harden your Docker setup.
The sudo command stands for "superuser do" and is used to execute commands with elevated privileges. Ubuntu restricts access to administrative tasks to prevent unintended or malicious changes to the system. With sudo, you can give certain users the ability to perform specific administrative tasks.
You're likely to work with multiple branches for different features, bug fixes, and releases. While managing these branches, you might run into situations where you need to temporarily save your work without committing it, and later apply it on the same or even a different branch.
