My current workflow to create the weekly reading posts Here is a breakdown of the simple, automated, and edited workflow I currently follow every week: 1. Capturing and Collecting Links I use Raindrop.io as a Google Chrome extension and mobile app to save the links I found interesting into a dedicated collection named “00-current”. This collection is configured to be the default saving location for all new bookmarks. 2. Processing (Sunday) I export all the bookmarks saved in the “00-current” collection as a .…

When deploying OpenShift IPI on baremetal, there is only so much you can tweak at installation time in terms of networking. Of course you can do changes after the installation, such as applying bonding configurations or vlan settings via machine configs… but what if you need those changes at installation time? In my case, I have an OpenShift environment composed by physical servers where each of them have 4 NICs. 1 unplugged NIC, 1 NIC connected to the provisioning network and 2 NICs connected to the same switch and to the same baremetal subnet.…

In this blog post I’m trying to perform the integration of an external registry with an OpenShift environment. The external registry can be any container registry, but in this case I’ve configured harbor to use certificates (self generated), the ’library’ repository in the harbor registry to be private (aka. require user/pass) and created an ’edu’ user account with permissions on that ’library’ repository. Harbor installation Pretty straightforward if following the docs, but for RHEL7:…

Introduction I’ve been using Nextcloud for a few years as my personal ‘file storage cloud’. There are official container images and docker-compose files to be able to run it easily. For quite a while, I’ve been using the nginx+redis+mariadb+cron docker-compose file as it has all the components to be able to run an ’enterprise ready’ Nextcloud, even if I’m only using it for personal use :) In this blog post I’m going to try to explain how do I moved from that docker-compose setup to a podman rootless and systemd one.…

Running a rootless Nextcloud pod Instead of running Nextcloud as independant containers, I’ve decided to leverage one of the multiple podman features which is being able to run multiple containers as a pod (like a kubernetes pod!) The main benefit to me of doing so is they they use a single network namespace, meaning all the containers running in the same pod can reach each other using localhost and you only need to expose the web interface.…
