The Great Migration

The Great Migration
Back in April, I wrote a summary post about the project I had been working on to migrate to a new k3s cluster from the original Rancher Kubernetes cluster that I created in 2020. My intention was to continue that series and detail each part of that project. Unfortunately, I ran into some technical problems which meant that not only did the cluster get shutdown, but I didn’t have time to even look at it.

This is especially disappointing because I’ve lost count of the number times I’ve come back to previous posts to refresh my memory about how I did something in the early days of this project.

Ansible what?

Ansible what?
Since the last update, I have been working to set up a basic way to automate common configuration and management tasks with Ansible. The basic Ansible setup uses a primary controller host with the Ansible software installed which has access to the various nodes to managed via Secure Shell (SSH). The managed hosts have minimal requirements. Namely they need to be able to receive incoming SSH connections, contain a Python interpreter to execute the commands, and usually an authentication mechanism such as SSH keys to allow logins without typing in a password.
