  • Debugging applications within Red Hat OpenShift containers

    There are debugging tools that can be used within containers but are not preinstalled in container base images. Tools such as strace or Valgrind must be included in a container during the container image build process.

    In order to add a debugging tool to a container, the container image build process must be configured to perform additional package installation commands. Whether or not package installation is permitted during the image build process depends on the method being used to build the container image. OpenShift provides several methods of building container images. These methods are called build strategies. Currently, OpenShift supports the Dockerfile, Source-to-Image (S2I), Pipeline, and Custom build strategies. Not all build strategies allow package installation: Of the most commonly-used strategies, the Dockerfile strategy permits package installation but the S2I strategy does not, because an S2I build process builds the container image in an unprivileged environment. A build process within an unprivileged environment lacks the ability to invoke package installation commands.

  • Fedora 33 To Finally Kill Off Python 2.6 Support

    Python 2.6 has been end-of-life all the way back to late 2013. However, Python 2.6 packaging for Fedora has kept upt in order to maintain some compatibility with RHEL/EPEL 6 having Python 2.6. But now with EPEL 6 reaching end-of-life as the extra packages for Red Hat Enterprise Linux 6 / CentOS 6, Fedora will gut its Python 2.6 support should anyone still be using it outside of the EPEL building/testing use-case. EPEL 6 is being retired in November 2020, similar to the expected release of Fedora 33.

  • Transformation – Simplify First

    While a bit of a stretch, there is some similarity to the dilemma that many companies are facing in this rapidly changing business environment. In my last blog, I talked about how companies are looking at the digital transformation of their business in order to stay competitive in a rapidly changing world. In a 2019 report by 451 Research commissioned by SUSE, 89% of survey respondents are considering, evaluating or executing their digital transformation strategy.

  • 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.
