  • Deploy a Java application using Helm, Part 2 | Red Hat Developer

    In the previous article in this series, you learned how to deploy Java applications to Red Hat JBoss Enterprise Application Platform (JBoss EAP) using Helm on Red Hat OpenShift. Developers can use the procedures in Part 1 to easily stand up traditional Java application servers on Kubernetes with predefined Kubernetes manifestos.

    What if you could have the same benefits when you develop microservices using JBoss EAP and Helm charts? JBoss EAP provides the Extension Pack (XP) to implement content trimming, packaging to a bootable JAR, and a MicroProfile specification including fault tolerance, monitoring, and tracing in support of microservices in the cloud. This article explains how to make a bootable JAR using JBoss EAP XP and Helm and deploy the application to OpenShift.

  • DevOps: 3 skills needed to support its future in the enterprise

    It’s no longer a question of if organizations need DevOps, but rather when they should adopt it, according to the DevOps Institute Upskilling 2021 report. That report finds that global enterprise adoption of DevOps at the project or multiple-project level is at 20 percent and 36 percent, respectively – and the skills needed for a successful DevOps journey span the categories of automation, human, technical, functional, and process knowledge.

    Whether you’re facing a skills gap in any of those key areas or you’re looking to expand your adoption of DevOps in the near future, keep the following considerations in mind:

  • Productivity lessons learned: 6 CIOs share tips for you and your team

    In our new hybrid work reality, many people in IT have enjoyed the flexibility to rewrite the rules on work-life balance. But it’s been a learning curve, says Kumud Kalia, CIO, Guardant Health.

    “As we moved to remote working for most of our employees, it became evident that time management had become much more of a juggling act between work, childcare/schooling, and miscellaneous personal priorities without a clear separation between these various activities. We already had flexible working hours for many of our employees, but we found that Zoom fatigue was real and added to the already unrelenting demands upon our people,” says Kalia.

    We asked CIOs who recently won the 2021 Bay Area CIO of the Year ORBIE Awards for their best productivity tips and lessons learned on work-life balance over the last year and a half. The awards were presented by the Bay Area CIO Leadership Association, a professional community that annually recognizes CIOs for their excellence in technology leadership.

    From being intentional and selective, to setting the right examples from the top, learn how these award-winning CIOs are making the most of their workday - and encouraging their teams to do the same.

  • Docker and Fedora 35

    In June of 2020, we published an article related to running Docker and Fedora 32. We described various workarounds that were required to run Docker, and we explained the bothersome situation at that time. But Docker has evolved, and it’s time to return to our previous tutorial. Thus, today we’ll talk about using Docker on Fedora Linux 35.

    With this guide, you should be able to easily recreate an existing development environment, without having to retool your entire pipeline. We’ll focus on getting the right packages, testing a few important scenarios, and helping you with tooling.

  • 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.
