Advent of Code 2023 – Day 17

In this video series, I try to challenge myself with the Advent of Code trials. Each solution will be published to Github, and I hope you will learn something from my coding mistakes and perhaps send some code my way on how you have done these challenges. I know by reading code, so this is…

I look into the Ceph Rook orchestrator that is the pre-cursor to the Ceph admin tooling. This installtion uses an Kubernetes installation in order to deploy a cluster and scale it up and down. Sadly the Ceph GUI don’t have much control so all changes are done with Kubernetes manifests from the command line.

We look into how to run workloads on the Azure Devops Pipeline, compare it with other similar solutions and also look at settings up a simple maven project for testing.

I look into installing and using TopGrade to upgrade all kinds of packages from a lot of different package managers in Linux and Windows. There is support for Mac as well but I was not able to test that.

In this video, we look into the database library Galera for MySQL or MariaDB. It enables replication over multiple hosts where each host is a master and replicated to the other hosts so it’s eventually consistent.
