KubeControllerManagerConfiguration

KubeCloudSharedConfiguration contains elements shared by both kube-controller manager and cloud-controller manager, but not genericconfig.

CloudProvider [Required] CloudProviderConfiguration CloudProviderConfiguration holds configuration for CloudProvider related features. ExternalCloudVolumePlugin [Required] string externalCloudVolumePlugin specifies the plugin to use when cloudProvider is &amp;quot;external&amp;quot;. It is currently used by the in repo cloud providers to handle node and volume control in the KCM. UseServiceAccountCredentials [Required] bool useServiceAccountCredentials indicates whether controllers should be run with individual service account credentials. AllowUntaggedCloud [Required] bool run with untagged cloud instances RouteReconciliationPeriod [Required] routeReconciliationPeriod is the period for reconciling routes created for Nodes by cloud provider.. NodeMonitorPeriod [Required] nodeMonitorPeriod is the period for syncing NodeStatus in NodeController. ClusterName [Required] string clusterName is the instance prefix for the cluster. ClusterCIDR [Required] string clusterCIDR is CIDR Range for Pods in cluster. AllocateNodeCIDRs [Required] bool AllocateNodeCIDRs enables CIDRs for Pods to be allocated and, if ConfigureCloudRoutes is true, to be set on the cloud provider. CIDRAllocatorType [Required] string CIDRAllocatorType determines what kind of pod CIDR allocator will be used. ConfigureCloudRoutes [Required] bool configureCloudRoutes enables CIDRs allocated with allocateNodeCIDRs to be configured on the cloud provider. NodeSyncPeriod [Required] nodeSyncPeriod is the period for syncing nodes from cloudprovider. Longer periods will result in fewer calls to cloud provider, but may delay addition of new nodes to cluster.
