Functions

func AllApplicationObjects

func AllApplicationObjects(configsLists ...ResourceConfigs) []client.Object

AllApplicationObjects returns all objects of class Application from the provided ResourceConfigs lists.

func AllRuntimeObjects

func AllRuntimeObjects(configsLists ...ResourceConfigs) []client.Object

AllRuntimeObjects returns all objects of class Runtime from the provided ResourceConfigs lists.

func DeployResourceConfigs

func DeployResourceConfigs(
	ctx context.Context,
	c client.Client,
	namespace string,
	clusterType ClusterType,
	managedResourceName string,
	managedResourceLabels map[string]string,
	registry *managedresources.Registry,
	allResources ResourceConfigs,
) error

DeployResourceConfigs deploys the provided ResourceConfigs <allResources> based on the ClusterType. For seeds, all resources are deployed via a single ManagedResource (independent of their Class). For shoots, all Runtime resources are applied directly with the client while all Application resources are deployed via a ManagedResource.

func DestroyResourceConfigs

func DestroyResourceConfigs(
	ctx context.Context,
	c client.Client,
	namespace string,
	clusterType ClusterType,
	managedResourceName string,
	resourceConfigs ...ResourceConfigs,
) error

DestroyResourceConfigs destroys the provided ResourceConfigs <allResources> based on the ClusterType. For seeds, all resources are deleted indirectly by deleting the ManagedResource. For shoots, all Runtime resources are deleted directly with the client while all Application resources are deleted indirectly by deleting the ManagedResource.

Types

type CentralLoggingConfiguration

type CentralLoggingConfiguration func() (CentralLoggingConfig, error)

CentralLoggingConfiguration is a function alias for returning configuration for the central logging.

type CentralMonitoringConfig

type CentralMonitoringConfig struct {
	// ScrapeConfigs are the scrape configurations for central Prometheus.
	ScrapeConfigs []string
	// CAdvisorScrapeConfigMetricRelabelConfigs are metric_relabel_configs for the cadvisor scrape config job.
	CAdvisorScrapeConfigMetricRelabelConfigs []string
}

CentralMonitoringConfig is a structure that contains configuration for the central monitoring stack.

type CentralMonitoringConfiguration

type CentralMonitoringConfiguration func() (CentralMonitoringConfig, error)

CentralMonitoringConfiguration is a function alias for returning configuration for the central monitoring.

type Class

type Class uint8

Class is a type alias for describing the class of a resource.

const (
	// Runtime means that the resource belongs to the runtime cluster (seed).
	Runtime Class = iota
	// Application means that the resource belongs to the target cluster (shoot).
	Application
)

type ClusterType

type ClusterType string

ClusterType is a type alias for a cluster type.

const (
	// ClusterTypeSeed is a constant for the 'seed' cluster type.
	ClusterTypeSeed ClusterType = "seed"
	// ClusterTypeShoot is a constant for the 'shoot' cluster type.
	ClusterTypeShoot ClusterType = "shoot"
)

type DeployMigrateWaiter

type DeployMigrateWaiter interface {
	Deployer
	Migrator
	MigrateWaiter
	Waiter
}

DeployMigrateWaiter controls and waits for the life-cycle and control-plane migration operations of a component.

type DeployWaiter

type DeployWaiter interface {
	Deployer
	Waiter
}

DeployWaiter controls and waits for life-cycle operations of a component.

func NoOp

func NoOp() DeployWaiter

NoOp does nothing.

func OpDestroyAndWait

func OpDestroyAndWait(dw ...Deployer) DeployWaiter

OpDestroyAndWait creates a DeployWaiter which calls Destroy instead of Deploy, and WaitCleanup.

func OpDestroyWithoutWait

func OpDestroyWithoutWait(dw ...Deployer) DeployWaiter

OpDestroyWithoutWait creates a DeployWaiter which calls Destroy instead of Deploy.

func OpWait

func OpWait(dw ...Deployer) DeployWaiter

OpWait creates a DeployWaiter which calls Wait .

type Deployer

type Deployer interface {
	// Deploy a component.
	Deploy(ctx context.Context) error
	// Destroy already deployed component.
	Destroy(ctx context.Context) error
}

Deployer is used to control the life-cycle of a component.

func OpDestroy

func OpDestroy(d ...Deployer) Deployer

OpDestroy creates a Deployer which calls Destroy instead of Deploy.

type IstioConfigInterface

type IstioConfigInterface interface {
	// ServiceName is the currently used name of the istio ingress service, which is responsible for the shoot cluster.
	ServiceName() string
	// Namespace is the currently used namespace of the istio ingress gateway, which is responsible for the shoot cluster.
	Namespace() string
	// LoadBalancerAnnotations contain the annotation to be used for the istio ingress service load balancer.
	LoadBalancerAnnotations() map[string]string
	// Labels contain the labels to be used for the istio ingress gateway entities.
	Labels() map[string]string
}

IstioConfigInterface contains functions for retrieving data from the istio configuration.

type MigrateWaiter

type MigrateWaiter interface {
	WaitMigrate(ctx context.Context) error
}

MigrateWaiter waits for the control-plane migration operations of a component to finish.

type Migrator

type Migrator interface {
	Restore(ctx context.Context, shootState *v1beta1.ShootState) error
