Network bandwidth use in kubernetes azure with no nodes RRS feed

  • Question

  • I created a kubernetes cluster with azure as explained in the microsoft tutorial with the command az aks create --resource-group myResourceGroup --name myAKSCluster --node-count 1 --generate-ssh-keys as described. I created the nodes as in the tutorial and then removed them. This means that I have the following result with the following command:

    $ kubectl get services
    NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
    kubernetes   ClusterIP   10.0.0.1     <none>        443/TCP   19h
    

    The problem is that even if I have only one cluster, I have a really big network usage and some cpu usage It's really big given that I'm using nothing in the services.

    Describing the problem in numberss is that in the last 12 hours, I have a network-in usage of almost 1GB and there's always a cpu usage of more than 13% for a process that it's mainly idle. Just for information, I started the cluster from scratch yesterday.

    Does anyone knows where this comes from? And how can I debug it?
