Prometheus

How to delete the PVC (volume) before terraform apply​

Scale down Prometheus​

kubectl -n <namespace> get sts
kubectl -n <namespace> scale statefulset prometheus --replicas=0

Delete the PVC​

kubectl -n <namespace> get pvc
kubectl -n <namespace> delete pvc data-prometheus-0

Data​

volume_mount {
  name       = "data"
  mount_path = "/data"
}

is mounting a persistent volume (PVC) into the Prometheus container at the path /data, which is where Prometheus stores its local time series data (TSDB).

info

/data is the default storage location for TSDB. --storage.tsdb.path=/data

Prometheus buffers all incoming data to disk before forwarding it via remote_write(VictoriaMetrics). And this protects against remote_write failure.
