Functions

func GetTenantNames

func GetTenantNames() (map[string]string, fail.Error)

GetTenantNames returns all known tenants names

func GetTenants

func GetTenants() ([]map[string]interface{}, fail.Error)

GetTenants returns all known tenants

func NullService

func NullService() *service

NullService creates a service instance corresponding to null value

func RankDRF

func RankDRF(t *abstract.HostTemplate) float32

RankDRF computes the Dominant Resource Fairness Rank of a host template

func Register

func Register(name string, provider providers.Provider)

Register a Client referenced by the provider name. Ex: "ovh", ovh.New() This function should be called by the init function of each provider to be registered in SafeScale

Types

type ByRankDRF

type ByRankDRF []*abstract.HostTemplate

ByRankDRF implements sort.Interface for []HostTemplate based on the Dominant Resource Fairness

func (ByRankDRF) Len

func (a ByRankDRF) Len() int

func (ByRankDRF) Less

func (a ByRankDRF) Less(i, j int) bool

Less returns what entry is less between indexes i and j, based on rank. If rank is identical, compares entry names

func (ByRankDRF) Swap

func (a ByRankDRF) Swap(i, j int)

type Service

type Service interface {
	CreateHostWithKeyPair(abstract.HostRequest) (*abstract.HostFull, *userdata.Content, *abstract.KeyPair, fail.Error)
	FilterImages(string) ([]*abstract.Image, fail.Error)
	FindTemplateBySizing(abstract.HostSizingRequirements) (*abstract.HostTemplate, fail.Error)
	FindTemplateByName(string) (*abstract.HostTemplate, fail.Error)
	FindTemplateByID(string) (*abstract.HostTemplate, fail.Error)
	GetProviderName() (string, fail.Error)
	GetMetadataBucket() (abstract.ObjectStorageBucket, fail.Error)
	GetMetadataKey() (*crypt.Key, fail.Error)
	InspectHostByName(string) (*abstract.HostFull, fail.Error)
	InspectSecurityGroupByName(networkID string, name string) (*abstract.SecurityGroup, fail.Error)
	ListHostsByName(bool) (map[string]*abstract.HostFull, fail.Error)
	ListTemplatesBySizing(abstract.HostSizingRequirements, bool) ([]*abstract.HostTemplate, fail.Error)
	ObjectStorageConfiguration() (objectstorage.Config, fail.Error)
	SearchImage(string) (*abstract.Image, fail.Error)
	TenantCleanup(bool) fail.Error // cleans up the data relative to SafeScale from tenant (not implemented yet)
	WaitHostState(string, hoststate.Enum, time.Duration) fail.Error
	WaitVolumeState(string, volumestate.Enum, time.Duration) (*abstract.Volume, fail.Error)

	// Provider --- from interface iaas.Providers ---
	providers.Provider

	LookupRuleInSecurityGroup(*abstract.SecurityGroup, *abstract.SecurityGroupRule) (bool, fail.Error)

	// Location --- from interface objectstorage.Location ---
	objectstorage.Location
}

Service consolidates Provider and ObjectStorage.Location interfaces in a single interface completed with higher-level methods

func UseService

func UseService(tenantName, metadataVersion string) (newService Service, ferr fail.Error)

UseService return the service referenced by the given name. If necessary, this function try to load service from configuration file
