This guide shows how to install and run DeepSeek on Ubuntu or RHEL/CentOS using the simplest methods (Docker or prebuilt binaries). You’ll learn to download the model, run a prompt, and verify output.
READ MOREMicrosoft has just announced a milestone: the Windows Subsystem for Linux (WSL) is now open-source. At Build 2025, the company confirmed that the WSL codebase has been published on GitHub, allowing anyone to download, build, and modify it. In the official announcement, Microsoft wrote “the code that powers WSL is now available on GitHub … and open sourced to the community”.
READ MOREKeeping disk pressure under control is a day-to-day chore for cluster admins. Left unchecked, old container images, completed builds, logs and stray volumes will quietly eat through node storage and the internal registry PVC, eventually triggering pod evictions or broken pushes. This post walks through a layered strategy for reclaiming and preventing waste—starting with the integrated image registry and ending with node-level log rotation.
READ MOREArgo CD is an open-source GitOps continuous delivery tool for Kubernetes. In GitOps, all deployment manifests live in a Git repo as the source of truth. Argo CD continuously monitors the Git repo and the Kubernetes cluster, and automatically (or manually) syncs the live state to match the desired state in Git. It also provides a web-based UI to see “desired vs live” status of your applications. In this tutorial, we’ll install Argo CD on a local Minikube cluster, access the Argo CD web UI, and deploy a sample GitOps application (a simple NGINX example) from a public repository.
READ MOREDocker lets you “ship code faster, standardize application operations, [and] seamlessly move code” to different machines. Official docs also remind us that Docker Engine runs on 64-bit Ubuntu (22.04 LTS “Jammy” or newer), so the steps below apply to Ubuntu 22.04 and later.
READ MORERHEL and CentOS provide powerful command-line tools for disk and storage management. To get started, identify existing disks and partitions using commands like lsblk (list block devices) or fdisk -l. For example, lsblk displays all disks and partitions in a clear tree view. The fdisk -l command reports disk sizes and partition tables; e.g., it might show a 30 GiB /dev/sda disk with /dev/sda2 marked as an LVM partition.
