  • Container and Kubernetes Security: It's Complicated

    Container technology is being increasingly used by organizations as a way to deploy applications and micro-services. The promise of containers is improved agility and portability, while potentially also reducing the attack surface. Though container technology can be helpful for security, it can also have its own set of risks.

    In a panel session at the recent Kubecon + CloudNativeCon EU event titled "Modern App Security Requires Containers" -- moderated by eSecurity Planet -- security experts from Cloud Native Computing Foundation (CNCF) project and Google debated what's wrong and what's right with container security.

  • Docker Defines Itself as the Open Choice for Containers at DockerCon 18

    Docker CEO Steve Singh kicked off his company's DockerCon 18 conference here today, offering the assembled crowd of container enthusiasts a clear vision of where Docker is going.

    For Docker Inc, the company behind the eponymous container system, a lot is at stake. This is the first DockerCon where the founder of the company, Solomon Hykes is not present. Hykes left Docker in March, as the company direction has increasingly focused on enterprise adoption and commercial market growth.

  • How to select the right enterprise Linux

    The decision to use any modern edition of that operating system, generally spoken as RHEL with a silent H, is usually based on a need for component stability, paid technical support, and long-term version support, said Red Hat's Ron Pacheco, director of global product management.

  • CentOS 7.4 & kernel 4.x - Worth the risk?

    The reasons why we have gathered here are many. A few weeks ago, my CentOS distro went dead. With the new kernel containing Spectre patches, it refused to load the Realtek Wireless drivers into memory. Moreover, patches also prevent manual compilation. This makes the distro useless, as it has no network connection. Then, in my CentOS 7.4 upgrade article - which was flawless, including the network piece, go figure - I wondered about the use of new, modern 4.x kernels in CentOS. Sounds like we have a real incentive here.

    In this tutorial, I will attempt to install and use the latest mainline kernel (4.16 when I typed this). The benefits should be many. I've seen improved performance, responsiveness and battery life in newer kernels compared to the 3.x branch. The Realtek Wireless woes of the disconnect kind (like a Spielberg movie) were also fixed in kernel 4.8.7 onwards, so that's another thing. Lastly, this would make CentOS a lean, mean and modern beast. Bravely onwards!

    [...]

    Now, I can breathe with relief, as I've delivered on my promise, and I gave you a full solution to the CentOS 7.4 Realtek issues post upgrade. I do not like to end articles on a cliffhanger, and definitely not carry the solution over to a follow-up article, but in this rare case, it was necessary. The mainline kernel upgrade is a topic of its own.

    The kernel installation worked fine, and thereafter, we seem to have gained on many fronts. The network issues are fully resolved, we can compile again, the performance seems improved despite worse figures in the system monitor, battery life and stability are not impaired in any way, and the CentOS box has fresh new life, wrapped in modern features and latest software. And none of this was meant to be in the first place, because CentOS is a server distro. Well, I hope you are happy. The one outstanding mission - Plasma 5. Once we have that, we can proudly claim to have created the ultimate Linux distro hybrid monster. Take care.

  • 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.
