// Package ec2rolecreds provides the credentials provider implementation for
|
|
// retrieving AWS credentials from Amazon EC2 Instance Roles via Amazon EC2 IMDS.
|
|
//
|
|
// # Concurrency and caching
|
|
//
|
|
// The Provider is not safe to be used concurrently, and does not provide any
|
|
// caching of credentials retrieved. You should wrap the Provider with a
|
|
// `aws.CredentialsCache` to provide concurrency safety, and caching of
|
|
// credentials.
|
|
//
|
|
// # Loading credentials with the SDK's AWS Config
|
|
//
|
|
// The EC2 Instance role credentials provider will automatically be the resolved
|
|
// credential provider in the credential chain if no other credential provider is
|
|
// resolved first.
|
|
//
|
|
// To explicitly instruct the SDK's credentials resolving to use the EC2 Instance
|
|
// role for credentials, you specify a `credentials_source` property in the config
|
|
// profile the SDK will load.
|
|
//
|
|
// [default]
|
|
// credential_source = Ec2InstanceMetadata
|
|
//
|
|
// # Loading credentials with the Provider directly
|
|
//
|
|
// Another way to use the EC2 Instance role credentials provider is to create it
|
|
// directly and assign it as the credentials provider for an API client.
|
|
//
|
|
// The following example creates a credentials provider for a command, and wraps
|
|
// it with the CredentialsCache before assigning the provider to the Amazon S3 API
|
|
// client's Credentials option.
|
|
//
|
|
// provider := imds.New(imds.Options{})
|
|
//
|
|
// // Create the service client value configured for credentials.
|
|
// svc := s3.New(s3.Options{
|
|
// Credentials: aws.NewCredentialsCache(provider),
|
|
// })
|
|
//
|
|
// If you need more control, you can set the configuration options on the
|
|
// credentials provider using the imds.Options type to configure the EC2 IMDS
|
|
// API Client and ExpiryWindow of the retrieved credentials.
|
|
//
|
|
// provider := imds.New(imds.Options{
|
|
// // See imds.Options type's documentation for more options available.
|
|
// Client: imds.New(Options{
|
|
// HTTPClient: customHTTPClient,
|
|
// }),
|
|
//
|
|
// // Modify how soon credentials expire prior to their original expiry time.
|
|
// ExpiryWindow: 5 * time.Minute,
|
|
// })
|
|
//
|
|
// # EC2 IMDS API Client
|
|
//
|
|
// See the github.com/aws/aws-sdk-go-v2/feature/ec2/imds module for more details on
|
|
// configuring the client, and options available.
