Functions

func CentralLoggingConfiguration

func CentralLoggingConfiguration() (component.CentralLoggingConfig, error)

CentralLoggingConfiguration returns a fluent-bit parser and filter for the monitoring logs.

Types

type DataMigration

type DataMigration struct {
	// Client is the client.
	Client client.Client
	// Namespace is the namespace.
	Namespace string
	// StorageCapacity is the storage capacity of the disk.
	StorageCapacity resource.Quantity
	// FullName is the full name of the component (e.g., prometheus-<name> or alertmanager-<name>).
	FullName string
	// OldSubPath is the subpath of the database on the old persistent volume. prometheus-operator assumes a subpath
	// `prometheus-db`, hence, if it was different before, it needs to be migrated.
	// If this field is not specified, the old subpath is assumed to be `prometheus-`.
	OldSubPath *string

	// ImageAlpine defines the container image of alpine.
	ImageAlpine string
	// StatefulSetName is the name of the old StatefulSet.
	StatefulSetName string
	// PVCNames is the list of names of the old PersistentVolumeClaims.
	PVCNames []string
}

DataMigration is a struct for migrating data from existing disks.

func (*DataMigration) ExistingPVTakeOverPrerequisites

func (d *DataMigration) ExistingPVTakeOverPrerequisites(ctx context.Context, log logr.Logger) (bool, []*corev1.PersistentVolume, []*corev1.PersistentVolumeClaim, error)

ExistingPVTakeOverPrerequisites performs the PV take over prerequisites.

func (*DataMigration) FinalizeExistingPVTakeOver

func (d *DataMigration) FinalizeExistingPVTakeOver(ctx context.Context, log logr.Logger, pvs []*corev1.PersistentVolume) error

FinalizeExistingPVTakeOver finalizes the PV take over.

func (*DataMigration) PrepareExistingPVTakeOver

func (d *DataMigration) PrepareExistingPVTakeOver(ctx context.Context, log logr.Logger, pvs []*corev1.PersistentVolume, oldPVCs []*corev1.PersistentVolumeClaim) error

PrepareExistingPVTakeOver prepares the PV take over.

type Interface

type Interface interface {
	component.Deployer
	// SetNamespaceUID sets the UID of the namespace into which the monitoring components shall be deployed.
	SetNamespaceUID(types.UID)
	// SetComponents sets the monitoring components.
	SetComponents([]component.MonitoringComponent)
	// SetWildcardCertName sets the WildcardCertName components.
	SetWildcardCertName(*string)
}

Interface contains functions for a monitoring deployer.

func New

func New(
	client client.Client,
	chartApplier kubernetes.ChartApplier,
	secretsManager secretsmanager.Interface,
	namespace string,
	values Values,
) Interface

New creates a new instance of Interface for the monitoring components.
