  • Rancher Labs Adds OS Optimized for Kubernetes

    Rancher Labs has made available a beta release of a lightweight operating system on which it envisions IT organizations will deploy its previously announced lightweight instance of Kubernetes dubbed k3s.

    Company CEO Sheng Liang says the main goal is to make it more convenient for IT organizations to use the same set of tools to deploy an instance of Kubernetes along with a k3OS operating system based on the open source Ubuntu kernel. Rancher Labs doesn’t envision IT organizations replacing instances of Linux that have already been deployed in with K3OS, but in circumstances where there has been no operating system standard set, k3OS should provide a more frictionless deployment option, he says.

    In fact, Liang notes the ability to deploy and update Kubernetes and the operating system it runs on from within the same user interface to access a common set of YAML files should be especially appealing to IT organizations that have embraced best DevOps processes to deliver ongoing rolling upgrades to their IT environments.

  • Manage your APIs deployed with Istio service mesh

    And, as explained in “Distributed microservices architecture: Istio, managed API gateways and, enterprise integration”, a service mesh does not relieve the need for an API management solution. A service mesh manages services and the connections between them, whereas an API management solution manages APIs and their consumers. In this article, I’ll describe how to manage APIs using the Red Hat Integration adapter for Istio.

    Red Hat Integration offers an API management capability that let companies build an ecosystem of consumers around their APIs and then drive new revenue from them.

  • OpenStack Looks to Help Define the Future of Open Infrastructure

    The OpenStack Foundation is continuing to grow its open-source efforts, including confirming new top-level projects and expanding its Ironic bare metal program, as part of the kickoff for the Open Infrastructure Summit.

    The Kata Containers secure container effort and the Zuul Continuous Integration/Continuous Deployment (CI/CD) projects have now been confirmed as top-level projects at the OpenStack Foundation, joining the group's namesake OpenStack cloud. While not yet a top-level project, the Airship lifecycle management project is also celebrating a major milestone with its 1.0 release.

    Additionally, the OpenStack Foundation is promoting its Ironic bare metal program as a way for organizations to deploy cloud resources on physical hardware.

  • 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.
