SUSE and Red Hat Leftovers

  • Skuba on SUSE CaaS Platform 4

    With SUSE CaaS Platform 4 we heard our customers feedback and decided to change what the lifecycle of the platform looks like.

    Previous versions of SUSE CaaS Platform included an administrator node that despite being useful for managing the whole platform, was another component to take care of, and an extra machine to take into account when deploying the platform.

    This administrator node used Salt to set up and maintain the Kubernetes cluster among the different nodes comprising your cluster.

    During this time, your feedback has been that a little more flexibility on the deployment was appreciated, so you could experiment with slightly different setups, even if they were for proof of concepts while you were fleshing out the details of production clusters.

  • Kubernetes Rolling Update Strategy in our production infra

    Kubernetes rolling update strategy means suppose we are running pod (containers) in our live infra and we want to update new changes into our running pod like build update, confrontational changes etc. While deployment new pod with new changes suppose our containers got stuck or failed due to any reason.

    So, we have to redeploy old pod with old changes again to avoid downtime of our application. This complete process is called rolling update strategy in Kubernetes.

    Kubernetes rolling update strategy

    Before moving to next we should aware about new pod deployment strategy of Kubernetes means how many new pods it will deploy at a time without taking downtime. Because high availability of our website is our first priority. So, while deploying new pod Kubernetes will deploy 25% or you can say one fourth of the total pod. Suppose we are running four pods first it will terminate 25% of total pod means one pod. Then it will launch 25% new pod and so on.

  • Tackle OpenStack networking woes with SUSE OpenStack Cloud Crowbar

    By far, the most difficult aspect of successfully deploying OpenStack is getting the networking right, a challenge that has caused many a well-intentioned IT team to throw up its hands and toss in the towel. Fortunately, SUSE OpenStack Cloud removes much of that pain by automating most of the network deployment and dramatically simplifying custom network set-ups.

  • Grow your virtualization environments without breaking the bank

    An IT director at a large financial services company shares the benefits and cost reductions they’ve experienced by switching to Red Hat Virtualization. In just three years, it’s paved the way for an efficient, stable and cost-effective virtualization environment.

  • How to Handle OpenShift Worker Nodes Resources in Overcommitted State

    One of the benefits in adopting a system like OpenShift is facilitating burstable and scalable workload. Horizontal application scaling involves adding or removing instances of an application to match demand. When OpenShift schedules a Pod, it’s important that the nodes have enough resources to actually run it. If a user schedules a large application (in the form of Pod) on a node with limited resources , it is possible for the node to run out of memory or CPU resources and for things to stop working!

    It’s also possible for applications to take up more resources than they should. This could be caused by a team spinning up more replicas than they need to artificially decrease latency or simply because of a configuration change that causes a program to go out of control and try to use 100% of the available CPU resources. Regardless of whether the issue is caused by a bad developer, bad code, or bad luck, what’s important is how a cluster administrator can manage and maintain control of the resources.

    In this blog, let’s take a look at how you can solve these problems using best practices.

  • How the new Quarkus extension for Visual Studio Code improves the development experience

    Earlier this year, we were introduced to Quarkus, the next-generation, container-first framework for Java applications. As expected, such new frameworks and technologies make way for new developer tools focused on making the development experience even better.

    The recent Quarkus extension for Visual Studio Code release aims to do just that, by bringing features specific to Quarkus project development within VS Code. The new VS Code extension is dependent on a couple of Java extensions for VS Code, so it is recommended that you have the Java Extension Pack installed. This article outlines what the Quarkus extension for VS Code has to offer: convenient features for an already convenient Java framework.

  • 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.
