  • CI/CD and the New Generation of Software Delivery: an Interview with Harness

    Continuous integration and continuous delivery (CI/CD) is all the rage in the modern world of software development. But actually what is this pipeline process? It's a method or set of principles for which development teams implement and deliver code more frequently and reliably.

    Continuous integration embodies a coding philosophy and set of practices propelling teams to implement small and frequent code changes into version control repositories, while the continuous delivery picks up where the CI ends and automates the application's delivery

    Many platforms, such as Jenkins and CircleCI, exist to help companies and teams streamline the development and integration of their software stacks, but not much exists in the way of easing and automating the process of delivery. And with what does exist, the solutions tend to fall short with features and functionality, or they are overly complicated to configure in the first place.

  • Networking Vendors Flock To Embrace Open-Source Istio Service Mesh

    With cloud-native, technologies, anchored at the core by the open-source Kubernetes container orchestration system, a series of disparate containers can be connected together to enable a microservices architecture for distributed application delivery.

    Managing networking for containers is something that can become complex with larger applications, which is a challenge that the open-source Istio service mesh effort aims to help solve. With the service mesh approach, rather than each individual container needing its own networking, Istio disaggregates microservices networking connectivity, enabling services to be connected in a mesh.

    Istio had its' 1.0 release on July 31 and at the recent KubeCon + CloudNativeCon NA 2018 conference that ran from Dec. 11-13, multiple networking vendors talked about their formal support, with different efforts.

  • Istio Multicluster on OpenShift

    Istio Multicluster is a feature of Istio–the basis of Red Hat OpenShift Service Mesh–that allows for the extension of the service mesh across multiple Kubernetes or Red Hat OpenShift clusters. The primary goal of this feature is to enable control of services deployed across multiple clusters with a single control plane.

    The main requirement for Istio multicluster to work is that the pods in the mesh and the Istio control plane can talk to each other. This implies that pods need to be able to open connections between clusters.

    In a previous article, this concept was demonstrated by connecting OpenShift SDNs with a network tunnel.

    Assuming this requirement can be met, either with the above approach or a similar one, the following describes how you can install Istio Multicluster.

  • Our Kubernetes deployment pipeline

    A few weeks ago I joined the web and design team here at Canonical, in the Base Squad, which is our backend team.
    One of the things that we are responsible for is deploying the code to our different staging and production environments.
    With multiple features being developed simultaneously, bugs being fixed, and some parts refactored on 27 websites and many projects it quickly becomes a complex problem to solve manually.

  • Kubernetes Federation V2 on OpenShift 3.11

    With datacenters spread across the globe, users are increasingly looking at ways to spread their applications and services across multiple locales or clusters. This need is driven by multiple use cases: from providing high availability, spreading load across multiple clusters while being resilient to individual cluster failures; to avoiding provider lock-in by using hybrid cloud solutions that have access to and make use of multiple clusters.

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.
