  • Kubernetes 1.23 Prevent PersistentVolume leaks when deleting out of order

    PersistentVolume (or PVs for short) are associated with Reclaim Policy. The Reclaim Policy is used to determine the actions that need to be taken by the storage backend on deletion of the PV. Where the reclaim policy is Delete, the expectation is that the storage backend releases the storage resource that was allocated for the PV. In essence, the reclaim policy needs to honored on PV deletion.

    With the recent Kubernetes v1.23 release, an alpha feature lets you configure your cluster to behave that way and honor the configured reclaim policy.

  • LOKI: An open-source enterprise cloud to call your own [Ed: The brand LOKI, in the context of Linux, is being hijacked by people who call that "LOKI: Linux OpenStack Kubernetes Infrastructure" and SJVN at ZDNet help them misuse the name, causing a problem to people who study history. They obviously knew about the name collision.]

    OpenStack has long been the foundation for open-source Infrastructure-as-a-Service (IaaS) clouds. Linux, of course, is the leading operating system for all clouds. And Kubernetes is the open-source software everyone uses to manage containers. Put them together, as the OpenInfra Foundation has, and you get LOKI: Linux OpenStack Kubernetes Infrastructure.

    OpenInfra executive director Jonathan Bryce says that just as the "LAMP [Linux, Apache, MySQL, Python/Perl/PHP] stack became the standard for deploying web applications, LOKI helps operators identify successful patterns and combinations of technologies to build production infrastructure."

  • 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.
