Functions

func CentralLoggingConfiguration

func CentralLoggingConfiguration() (component.CentralLoggingConfig, error)

CentralLoggingConfiguration returns a fluent-bit parser and filters for the gardener-resource-manager logs.

func GetMutatingWebhookConfigurationWebhooks

func GetMutatingWebhookConfigurationWebhooks(namespaceSelector *metav1.LabelSelector, secretServerCA *corev1.Secret, buildClientConfigFn func(*corev1.Secret, string) admissionregistrationv1.WebhookClientConfig) []admissionregistrationv1.MutatingWebhook

GetMutatingWebhookConfigurationWebhooks returns the MutatingWebhooks for the resourcemanager component for reuse between the component and integration tests.

Types

type Interface

type Interface interface {
	component.DeployWaiter
	component.MonitoringComponent
	// GetReplicas gets the Replicas field in the Values.
	GetReplicas() *int32
	// SetReplicas sets the Replicas field in the Values.
	SetReplicas(*int32)
	// SetSecrets sets the secrets.
	SetSecrets(Secrets)
}

Interface contains functions for a gardener-resource-manager deployer.

func New

func New(
	client client.Client,
	namespace string,
	secretsManager secretsmanager.Interface,
	image string,
	values Values,
) Interface

New creates a new instance of the gardener-resource-manager.

type Secrets

type Secrets struct {
	// BootstrapKubeconfig is the kubeconfig of the gardener-resource-manager used during the bootstrapping process. Its
	// token requestor controller will request a JWT token for itself with this kubeconfig.
	BootstrapKubeconfig *component.Secret
	// contains filtered or unexported fields
}

Secrets is collection of secrets for the gardener-resource-manager.

type VPAConfig

type VPAConfig struct {
	// MinAllowed specifies the minimal amount of resources that will be recommended
	// for the container.
	MinAllowed corev1.ResourceList
}

VPAConfig contains information for configuring VerticalPodAutoscaler settings for the gardener-resource-manager deployment.

	SecretNameServerCA string
	// SyncPeriod configures the duration of how often existing resources should be synced
	SyncPeriod *time.Duration
	// TargetDiffersFromSourceCluster states whether the target cluster is a different one than the source cluster
	TargetDiffersFromSourceCluster bool
	// TargetDisableCache disables the cache for target cluster and always talk directly to the API server (defaults to false)
	TargetDisableCache *bool
	// WatchedNamespace restricts the gardener-resource-manager to only watch ManagedResources in the defined namespace.
	// If not set the gardener-resource-manager controller watches for ManagedResources in all namespaces
	WatchedNamespace *string
	// Version is the Kubernetes version for the Kubernetes components.
	Version *semver.Version
	// VPA contains information for configuring VerticalPodAutoscaler settings for the gardener-resource-manager deployment.
