@Benedict-CS Look at your log...it seems like your port mapping is already in use with some other container or so.

FATA[0000] listen tcp :9579: bind: address already in use source="iperf3_exporter.go:249"

@Technikte This is weird because the only service that listens on port 9579 is the iperf3_exporter.
