Bandwidth usage

I have a baremetal rancher OS running a cluster registered on Rancher and I have a very limited satellite bandwidth connection.

By running docker run -it --net=host --pid=host --rm k3ck3c/nethogs eth1 I can see that it’s consuming about 62 KB/s of download and 1.5 KB/s of upload.

I didn’t enable any prometheus metrics nor have any pods running, besides the cluster, I also have no tabs on Rancher Server visualising the cluster.

Why is that so that it consumes this amount of bandwidth and is there a way to consume less?

Many thanks.
