Provider support details

In order to configure a cluster with API Server extra args, you need to configure your cluster by updating the cluster configuration file to include the details below. The feature flag API_SERVER_EXTRA_ARGS_ENABLED=true needs to be set as an environment variable.

This is a generic template with some example API Server extra args configuration below for reference:

apiVersion: anywhere.eks.amazonaws.com/v1alpha1
kind: Cluster
metadata:
   name: my-cluster-name
spec:
    ...
    controlPlaneConfiguration:
        apiServerExtraArgs:
            ...
            disable-admission-plugins: "DefaultStorageClass,DefaultTolerationSeconds"
            enable-admission-plugins: "NamespaceAutoProvision,NamespaceExists"

The above example configures the disable-admission-plugins and enable-admission-plugins options of the API Server to enable additional admission plugins or disable some of the default ones. You can configure any of the API Server options using the above template.
