Overview

Package s3 provides a storagedriver.StorageDriver implementation to store blobs in Amazon S3 cloud storage.

This package leverages the official aws client library for interfacing with S3.

Because S3 is a key, value store the Stat call does not support last modification time for directories (directories are an abstraction for key, value stores)

Keep in mind that S3 guarantees only read-after-write consistency for new objects, but no read-after-update or list-after-write consistency.

Functions

func Sign

func Sign(req *request.Request)

Sign requests with signature version 2.

Will sign the requests with the service config's Credentials object Signing is skipped if the credentials is the credentials.AnonymousCredentials object.

Types

type Driver

type Driver struct {
	// contains filtered or unexported fields
}

Driver is a storagedriver.StorageDriver implementation backed by Amazon S3 Objects are stored at absolute keys in the provided bucket.

func FromParameters

func FromParameters(parameters map[string]interface{}) (*Driver, error)

FromParameters constructs a new Driver with a given parameters map Required parameters: - accesskey - secretkey - region - bucket - encrypt

func New

func New(params DriverParameters) (*Driver, error)

New constructs a new Driver with the given AWS credentials, region, encryption flag, and bucketName

func (*Driver) S3BucketKey

func (d *Driver) S3BucketKey(path string) string

S3BucketKey returns the s3 bucket key for the given storage driver path.
