Functions

func AddDefaultStoragePools

func AddDefaultStoragePools(p storage.Provider, pm PoolManager) error

AddDefaultStoragePools adds the default storage pools for the given provider to the given pool manager. This is called whenever a new model is created.

Types

type MemSettings

type MemSettings struct {
	Settings map[string]map[string]interface{}
}

MemSettings is an in-memory implementation of SettingsManager. This type does not provide any goroutine-safety.

func (MemSettings) CreateSettings

func (m MemSettings) CreateSettings(key string, settings map[string]interface{}) error

CreateSettings is part of the SettingsManager interface.

func (MemSettings) ListSettings

func (m MemSettings) ListSettings(keyPrefix string) (map[string]map[string]interface{}, error)

ListSettings is part of the SettingsManager interface.

func (MemSettings) ReadSettings

func (m MemSettings) ReadSettings(key string) (map[string]interface{}, error)

ReadSettings is part of the SettingsManager interface.

func (MemSettings) RemoveSettings

func (m MemSettings) RemoveSettings(key string) error

RemoveSettings is part of the SettingsManager interface.

type PoolManager

type PoolManager interface {
	// Create makes a new pool with the specified configuration and persists it to state.
	Create(name string, providerType storage.ProviderType, attrs map[string]interface{}) (*storage.Config, error)

	// Delete removes the pool with name from state.
	Delete(name string) error

	// Get returns the pool with name from state.
	Get(name string) (*storage.Config, error)

	// List returns all the pools from state.
	List() ([]*storage.Config, error)
}

A PoolManager provides access to storage pools.

func New

func New(settings SettingsManager, registry storage.ProviderRegistry) PoolManager

New returns a PoolManager implementation using the specified state.

type SettingsManager

type SettingsManager interface {
	CreateSettings(key string, settings map[string]interface{}) error
	ReadSettings(key string) (map[string]interface{}, error)
	RemoveSettings(key string) error
	ListSettings(keyPrefix string) (map[string]map[string]interface{}, error)
}
