  • Kubernetes Snaps: The Quick Version

    When we built the Canonical Distribution of Kubernetes (CDK), one of our goals was to provide snap packages for the various Kubernetes clients and services: kubectl, kube-apiserver, kubelet, etc.

    While we mainly built the snaps for use in CDK, they are freely available to use for other purposes as well. Let’s have a quick look at how to install and configure the Kubernetes snaps directly.

  • Kubernetes is Transforming Operations in the Enterprise

    At many organizations, managing containerized applications at scale is the order of the day (or soon will be). And few open source projects are having the impact in this arena that Kubernetes is.

    Above all, Kubernetes is ushering in “operations transformation” and helping organizations make the transition to cloud-native computing, says Craig McLuckie co-founder and CEO of Heptio and a co-founder of Kubernetes at Google, in a recent free webinar, ‘Getting to Know Kubernetes.’ Kubernetes was created at Google, which donated the open source project to the Cloud Native Computing Foundation.

  • Kubernetes gains momentum as big-name vendors flock to Cloud Native Computing Foundation

    Like a train gaining speed as it leaves the station, the Cloud Native Computing Foundation is quickly gathering momentum, attracting some of the biggest names in tech. In the last month and a half alone AWS, Oracle, Microsoft, VMware and Pivotal have all joined.

    It’s not every day you see this group of companies agree on anything, but as Kubernetes has developed into an essential industry tool, each of these companies sees it as a necessity to join the CNCF and support its mission. This is partly driven by customer demand and partly by the desire to simply have a say in how Kubernetes and other related cloud-native technologies are developed.

  • The Cloud-Native Architecture: One Stack, Many Options

    As the chief technology officer of a company specialized in cloud native storage, I have a first hand view of the massive transformation happening right now in enterprise IT. In short, two things are happening in parallel right now that make it radically simpler to build, deploy and run sophisticated applications.

    The first is the move to the cloud. This topic has been discussed so much that I won’t try to add anything new. We all know it’s happening, and we all know that its impact is huge.

  • Sysadmin 101: Leveling Up

    I hope this description of levels in systems administration has been helpful as you plan your own career. When it comes to gaining experience, nothing quite beats making your own mistakes and having to recover from them yourself. At the same time, it sure is a lot easier to invite battle-hardened senior sysadmins to beers and learn from their war stories. I hope this series in Sysadmin 101 fundamentals has been helpful for those of you new to the sysadmin trenches, and also I hope it helps save you from having to learn from your own mistakes as you move forward in your career.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
