Background
During one of my assignments, we were evaluating Karpenter. While being a rather cool piece of software, it caused us some pain. The general idea was to deploy Grafana Loki and use an autoscaling tool to maintain node pools automatically.
Karpenter seemed to be the perfect tool for this use case. However, it had (maybe due to my misconfiguration) some undesired side effects. It was quite aggressive in adding and removing nodes, which caused disruptions.
