Types ¶

type DeviceMetadata ¶

type DeviceMetadata struct {
	Type    string `json:"type"`
	Bus     string `json:"bus,omitempty"`
	Serial  string `json:"serial,omitempty"`
	Address string `json:"address,omitempty"`
}

DeviceMetadata is a single/simplified data structure for all kinds of device metadata types.

type IMetadata ¶

type IMetadata interface {
	GetInstanceID() (string, error)
	GetAvailabilityZone() (string, error)
}

IMetadata implements GetInstanceID & GetAvailabilityZone

var MetadataService IMetadata

MetadataService instance of IMetadata

func GetMetadataProvider ¶

func GetMetadataProvider(order string) IMetadata

GetMetadataProvider retrieves instance of IMetadata

type Metadata ¶

type Metadata struct {
	UUID             string           `json:"uuid"`
	Name             string           `json:"name"`
	AvailabilityZone string           `json:"availability_zone"`
	Devices          []DeviceMetadata `json:"devices,omitempty"`
}

Metadata has the information fetched from OpenStack metadata service or config drives. Assumes the "latest" meta_data.json format.

func Get ¶

func Get(order string) (*Metadata, error)

Get retrieves metadata from either config drive or metadata service. Search order depends on the order set in config file.

type MetadataOpts ¶

type MetadataOpts struct {
	SearchOrder    string     `gcfg:"search-order"`
	RequestTimeout MyDuration `gcfg:"request-timeout"`
}

MetadataOpts is used for configuring how to talk to metadata service or config drive

type MyDuration ¶

type MyDuration struct {
	time.Duration
}

MyDuration is the encoding.TextUnmarshaler interface for time.Duration

func (*MyDuration) UnmarshalText ¶

func (d *MyDuration) UnmarshalText(text []byte) error

UnmarshalText is used to convert from text to Duration
