An EC2InstanceIdentityDocument provides the shape for unmarshaling an instance identity document

type EC2Metadata added in v0.10.0

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 added in v0.10.0

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.

If an unmodified HTTP client is provided from the stdlib default, or no client the EC2RoleProvider's EC2Metadata HTTP client's timeout will be shortened. To disable this set Config.EC2MetadataDisableTimeoutOverride to false. Enabled by default.

func (*EC2Metadata) Available added in v0.10.0

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) GetDynamicData added in v1.1.12

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

GetDynamicData uses the path provided to request information from the EC2 instance metadata service for dynamic data. The content will be returned as a string, or error if the request failed.

func (*EC2Metadata) GetInstanceIdentityDocument added in v1.1.12

func (c *EC2Metadata) GetInstanceIdentityDocument() (EC2InstanceIdentityDocument, error)

GetInstanceIdentityDocument retrieves an identity document describing an instance. Error is returned if the request fails or is unable to parse the response.

func (*EC2Metadata) GetMetadata added in v0.10.0

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

GetMetadata uses the path provided to request information from the EC2 instance metdata service. The content will be returned as a string, or error if the request failed.

func (*EC2Metadata) GetUserData added in v1.4.15

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

GetUserData returns the userdata that was configured for the service. If there is no user-data setup for the EC2 instance a "NotFoundError" error code will be returned.

func (*EC2Metadata) IAMInfo added in v1.1.15

func (c *EC2Metadata) IAMInfo() (EC2IAMInfo, error)

IAMInfo retrieves IAM info from the metadata API

func (*EC2Metadata) Region added in v0.10.0

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