Route Controller error listing routes filling up kube-controller logs

[chadningle]

The k8s ccm route-controller is querying the AWS API every 10 seconds, which is a normal interval, with DescribeRouteTables with no Request Parameters nor Filtering. The documentation says it is supposed to us a tag filter when querying but cloudtrail doesn't seem to agree.

"requestParameters": {
    "routeTableIdSet": {},
    "filterSet": {}
},

1. Clone the repo and run the cloud-enabled example.
2. SSH to a Master node.
3. tail -f /var/log/containers/kube-controller-(tab to completion)

Is there a way we can disable the route-controller in the k8s ccm that rke2 is using? The k8s fix for this is to set this in the yaml in the controller command section: - --configure-cloud-routes=false

https://kubernetes.io/docs/tasks/administer-cluster/running-cloud-controller/

these flags will vary for every cloud provider

    - --allocate-node-cidrs=true
    - --configure-cloud-routes=true
    - --cluster-cidr=172.17.0.0/16

Adding this line to the rke2_config variable resolved this for me:

kube-controller-manager-arg: "configure-cloud-routes=false"
