Functions

func NewPodCommandExecutor

func NewPodCommandExecutor(restClientConfig *rest.Config, restClient poster) podCommandExecutor

NewPodCommandExecutor creates a new podCommandExecutor.

Types

type Backupper

type Backupper interface {
	// Backup takes a backup using the specification in the api.Backup and writes backup and log data
	// to the given writers.
	Backup(backup *api.Backup, backupFile, logFile io.Writer, actions []ItemAction) error
}

Backupper performs backups.

func NewKubernetesBackupper

func NewKubernetesBackupper(
	discoveryHelper discovery.Helper,
	dynamicFactory client.DynamicFactory,
	podCommandExecutor podCommandExecutor,
	snapshotService cloudprovider.SnapshotService,
) (Backupper, error)

NewKubernetesBackupper creates a new kubernetesBackupper.

type ItemAction

type ItemAction interface {
	// AppliesTo returns information about which resources this action should be invoked for.
	// An ItemAction's Execute function will only be invoked on items that match the returned
	// selector. A zero-valued ResourceSelector matches all resources.
	AppliesTo() (ResourceSelector, error)

	// Execute allows the ItemAction to perform arbitrary logic with the item being backed up,
	// including mutating the item itself prior to backup. The item (unmodified or modified)
	// should be returned, along with an optional slice of ResourceIdentifiers specifying
	// additional related items that should be backed up.
	Execute(item runtime.Unstructured, backup *api.Backup) (runtime.Unstructured, []ResourceIdentifier, error)
}

ItemAction is an actor that performs an operation on an individual item being backed up.

func NewBackupPVAction

func NewBackupPVAction(log logrus.FieldLogger) ItemAction

func NewPodAction

func NewPodAction(log logrus.FieldLogger) ItemAction

NewPodAction creates a new ItemAction for pods.

type ItemBackupper

type ItemBackupper interface {
	// contains filtered or unexported methods
}

type ResourceIdentifier

type ResourceIdentifier struct {
	schema.GroupResource
	Namespace string
	Name      string
}

ResourceIdentifier describes a single item by its group, resource, namespace, and name.

type ResourceSelector

type ResourceSelector struct {
	// IncludedNamespaces is a slice of namespace names to match. All
	// namespaces in this slice, except those in ExcludedNamespaces,
	// will be matched. A nil/empty slice matches all namespaces.
	IncludedNamespaces []string
	// ExcludedNamespaces is a slice of namespace names to exclude.
	// All namespaces in IncludedNamespaces, *except* those in
	// this slice, will be matched.
	ExcludedNamespaces []string
	// IncludedResources is a slice of resources to match. Resources
	// may be specified as full names (e.g. "services") or abbreviations
	// (e.g. "svc"). All resources in this slice, except those in
	// ExcludedResources, will be matched. A nil/empty slice matches
	// all resources.
	IncludedResources []string
	// ExcludedResources is a slice of resources to exclude.
	// Resources may be specified as full names (e.g. "services") or
	// abbreviations (e.g. "svc"). All resources in IncludedResources,
	// *except* those in this slice, will be matched.
	ExcludedResources []string
	// LabelSelector is a string representation of a selector to apply
	// when matching resources. See "k8s.io/apimachinery/pkg/labels".Parse()
	// for details on syntax.
	LabelSelector string
}

ResourceSelector is a collection of included/excluded namespaces, included/excluded resources, and a label-selector that can be used to match a set of items from a cluster.
