Jenkins as a Docker container is a powerful way to leverage the benefits of containerization in your CI/CD workflows. Docker allows you to create, manage, and deploy Jenkins environments efficiently, enabling consistent builds across various environments.
One of the key aspects of Docker security is ensuring that the images you build and deploy are free from vulnerabilities. A vulnerable Docker image could introduce a backdoor for attackers or expose your applications to known exploits.
When GRUB suddenly stopped auto-booting and waited forever for input, the cause wasn’t Linux, the kernel, or updates — but a tiny USB keyboard dongle. This post follows a real debugging journey through BIOS quirks, USB initialization, and bootloader surprises.
The concepts of file permissions and ownership are fundamental to securing the system and ensuring that users and processes have the appropriate access to files and directories. Proper understanding of these permissions helps maintain the security, stability, and usability of the operating system.
In the previous post, we discussed how to use git stash to temporarily save changes without committing them. Now, we'll dive deeper into how to apply and clear stashes when you're ready to bring your changes back or clean up your stash history.
Python is a powerful, versatile language that’s widely spread. In this post, we'll cover the essentials of Python. Step-by-step installation and a first look at Python syntax. Writing your first "Hello, World!" script and understanding core programming concepts in Python.
A complete zero-to-hero guide to GRUB on modern Ubuntu. Learn how the bootloader works, how to configure it safely, and how to recover from broken boots, dual-boot issues, and Secure Boot problems.
As organizations increasingly adopt containerization for their applications, Kubernetes has emerged as the leading platform for container orchestration. While Docker helps in packaging and deploying applications in containers.
As your Jenkins workloads scale, managing agents efficiently becomes critical. One way to handle this challenge is through dynamic agent provisioning, which allows Jenkins to create and destroy agents on-demand.
Gamescope is Valve’s lightweight nested compositor for Linux gaming. It lets you control resolution scaling, FPS limits, HDR, and adaptive sync with almost no overhead—acting like a smart performance layer between your game and the desktop compositor.
Deploying Jenkins in a Docker container has become a popular choice. Docker provides a lightweight and consistent environment for running Jenkins, allowing teams to easily manage and scale their CI/CD processes. This post will guide you through creating a Dockerfile for Jenkins.
Docker provides an efficient way to package and run applications. However, security is a critical concern when working with containers, especially in multi-tenant environments or production deployments. One of the fundamental security best practices is running Docker containers with non-root users.
