Docker

If you have looked around this site, or know me and have heard me discuss it, I have an honest to goodness Red Hat Enterprise Linux subscription. I am not talking about the rebuilt version called Rocky Linux, which is the successor to CentOS after Red Hat changed that distro from being just a rebuilt/relabeled version of the corresponding RHEL version to a stream version sitting somewhere behind Fedora and before RHEL. 

I have been a PHP programmer for years, having used it without frameworks, to frameworks like Zend Framework (now rebranded as Laminas) and Laravel, to custom in-house frameworks. At the same time, I went from using it with JavaScript in its various versions, to using the jQuery library with jQuery UI and various add-ons like DataTables.

In setting up my CI/CD pipeline for some demo Docker containers recently, I ran into a frustrating, yet puzzling issue while trying to get Docker Swarm working. Indeed, it left me like "Johnny" Number 5 from the movie Short Circuit with questions, queries, and posers.

This is a bit of a continuation of this article, where I talk about Jenkins, Drupal and CI/CD.  In this case, I am not talking about Drupal, but about a Python/Django project I have been working on to track job applications rather than using a Google spreadsheet, which was getting a bit unweildy with hundreds of rows. This project is up on GitHub, here, and I will be referring to this project through part of this article.
