Constants

const ServiceName = "ec2metadata"

ServiceName is the name of the service.

Types

type EC2Metadata

type EC2Metadata struct {
	*client.Client
}

A EC2Metadata is an EC2 Metadata service Client.

func New

func New(p client.ConfigProvider, cfgs ...*aws.Config) *EC2Metadata

New creates a new instance of the EC2Metadata client with a session. This client is safe to use across multiple goroutines.

Example:

// Create a EC2Metadata client from just a session.
svc := ec2metadata.New(mySession)

// Create a EC2Metadata client with additional configuration
svc := ec2metadata.New(mySession, aws.NewConfig().WithLogLevel(aws.LogDebugHTTPBody))

func NewClient

func NewClient(cfg aws.Config, handlers request.Handlers, endpoint, signingRegion string, opts ...func(*client.Client)) *EC2Metadata

NewClient returns a new EC2Metadata client. Should be used to create a client when not using a session. Generally using just New with a session is preferred.

func (*EC2Metadata) Available

func (c *EC2Metadata) Available() bool

Available returns if the application has access to the EC2 Metadata service. Can be used to determine if application is running within an EC2 Instance and the metadata service is available.

func (*EC2Metadata) GetMetadata

func (c *EC2Metadata) GetMetadata(p string) (string, error)

GetMetadata uses the path provided to request

func (*EC2Metadata) Region

func (c *EC2Metadata) Region() (string, error)

Region returns the region the instance is running in.
