The retention time is a command line flag for the Prometheus
binary. You have to set `--storage.tsdb.retention.time=30d` in your
case.

I don't know Helm charts well enough to tell you exactly how to change
command line flags, but it should be straight forward, I assume.

Add args to your deployment.yaml or statefulset.yaml

args:

            - --storage.tsdb.retention.time={{ .Values.server.retention }}

            - --storage.tsdb.wal-compression

            - --storage.tsdb.retention.size={{ .Values.server.retentionSize }}

            - --config.file=/etc/config/prometheus.yml
