Why some prometheus alerts in k8s can confuse
Recently I was installing a kubernetes cluster as I usually do for my tests. However, as those machines were bare metal servers that some colleagues have recycled, we decided to keep it running and try to maintain it by ourselves.
First thing I did was a simple bot to send the alerts to a telegram channel. That was something I did not do in the past, because I do not care about monitoring as my clusters were ephemeral.
