Building multi-architecture images become more and more useful. Indeed, many recent computers use ARM processors architecture. Examples include MacBooks using M(x) processors, and Amazon EC2 instances using AWS Graviton processors. However, the diversification of processor architectures adds a new level of complexity to the creation of container images. Indeed, the construction has to cope with different instruction sets. Docker buildx,…

When creating the cluster, a management cluster name is generated with the format c-m-xxxxxxxx, but the ClusterRoleTemplateBinding requires the cluster name to work. After digging into Rancher source code, I found out how to set the management cluster name. So let’s start! Force the cluster name with RKE2 templates…
In my previous blog post, we started to explore how to increase the Time-to-Market (TTM) of your simple application. We improved it and to go further we will now leverage containerization.

by Alexandre Nestor Introduction Keeping and using passwords in scripts is often an overlooked task, at least in the initial stages of development.This behavior poses serious security problems, and quite often, especially in scripts, one can find plaintext passwords.If the project uses Git, then the versions of git that contain the passwords are visible in the project history.The use of…
As I am working on developing a component for YaK, I have to stick to standards on how to write code in Ansible as well as many other constraints regarding security.
