  • Thoughts of Dev: One piece of advice to a new developer – IBM Developer

    We all have to start someplace in our careers and as a developer, you have a LOT of options and decisions to make. From your first job and industry, programming language to learn, training, soft skills and more. The choices are endless and each right decision (and sometimes wrong decision) helps bring you to where you are today in your career. Looking back, if you could give an important piece of advice to a junior developer, what would you tell them?

  • How Red Hat celebrated Hispanic Heritage month

    We’ve always maintained that a diverse and inclusive organization thrives when people from different backgrounds feel comfortable being their full self when they’re at work. This includes sharing and celebrating holidays and traditions with colleagues that are important to their culture or heritage. At Red Hat, Diversity and Inclusion (D&I) communities are a rich source for associates to have new experiences and learn from others with different backgrounds. Our D&I communities are global, associate-led groups focused on fostering diversity and inclusion, knowledge sharing, learning and development, and relationship building.

    Unidos, our Latinx and Hispanic D&I community, recently led its first formal recognition of Hispanic Heritage Month. The team organized virtual events for associates including a live cooking session of traditional hispanic cuisine (arepas con carne or a patacon/jibaritos sandwich anyone?) and a panel discussion featuring Red Hatters from Unidos discussing different aspects of Latinx and Hispanic culture including language, traditional family dynamics and the experience of being an immigrant.

  • Multi-stack deployments for the edge with Red Hat OpenStack Platform 16.1

    In past releases, Red Hat OpenStack Platform director has used a single Heat stack for the overcloud deployment. With the Train release, it’s now possible to use multiple stacks for a single cloud deployment. Multiple stacks is advantageous to edge deployments as it allows for each distributed edge site to be managed and scaled independently, minimizing operational complexity. First, let’s review the concept of a "stack" in director, as the term can often have overloaded meanings in software engineering.

  • Build custom Ansible modules using Python's Pexpect

    When developing automation you may be faced with challenges that are simply too complicated or tedious to accomplish with Ansible alone. There may even be cases where you are told that "it can’t be automated." However, when you combine the abilities of Ansible and custom Python using the Pexpect module, then you are able to automate practically anything you can do on the command line. In this post we will discuss the basics of creating a custom Ansible module in Python.

    [...]

    If these tools also provided a non-interactive mode or config/script input we would not need to do this. To overcome this situation we need to use Python with Pexpect. The native Ansible expect module provides a simple interface to this functionality and should be evaluated before writing a custom module. However, when you need more complex interactions, want specific data returned or want to provide a re-usable and simpler interface to an underlying program for others to consume, then custom development is warranted.

  • 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.
