// Package credentials provides credential retrieval and management
|
||
|
|
// for S3 compatible object storage.
|
||
|
|
//
|
||
|
|
// By default the Credentials.Get() will cache the successful result of a
|
||
|
|
// Provider's Retrieve() until Provider.IsExpired() returns true. At which
|
||
|
|
// point Credentials will call Provider's Retrieve() to get new credential Value.
|
||
|
|
//
|
||
|
|
// The Provider is responsible for determining when credentials have expired.
|
||
|
|
// It is also important to note that Credentials will always call Retrieve the
|
||
|
|
// first time Credentials.Get() is called.
|
||
|
|
//
|
||
|
|
// Example of using the environment variable credentials.
|
||
|
|
//
|
||
|
|
// creds := NewFromEnv()
|
||
|
|
// // Retrieve the credentials value
|
||
|
|
// credValue, err := creds.Get()
|
||
|
|
// if err != nil {
|
||
|
|
// // handle error
|
||
|
|
// }
|
||
|
|
//
|
||
|
|
// Example of forcing credentials to expire and be refreshed on the next Get().
|
||
|
|
// This may be helpful to proactively expire credentials and refresh them sooner
|
||
|
|
// than they would naturally expire on their own.
|
||
|
|
//
|
||
|
|
// creds := NewFromIAM("")
|
||
|
|
// creds.Expire()
|
||
|
|
// credsValue, err := creds.Get()
|
||
|
|
// // New credentials will be retrieved instead of from cache.
|
||
|
|
//

||
|
|
//
|

|
|
// Custom Provider
|
||
|
|
//
|
||
|
|
// Each Provider built into this package also provides a helper method to generate
|
||
|
|
// a Credentials pointer setup with the provider. To use a custom Provider just
|
||
|
|
// create a type which satisfies the Provider interface and pass it to the
|
||
|
|
// NewCredentials method.
|
||
|
|
//
|
||
|
|
// type MyProvider struct{}
|
||
|
|
// func (m *MyProvider) Retrieve() (Value, error) {...}
|
||
|
|
// func (m *MyProvider) IsExpired() bool {...}
|
||
|
|
//
|
||
|
|
// creds := NewCredentials(&MyProvider{})
|
||
|
|
// credValue, err := creds.Get()
