Overview

Package swift provides a storagedriver.StorageDriver implementation to store blobs in Openstack Swift object storage.

This package leverages the ncw/swift client library for interfacing with Swift.

It supports both TempAuth authentication and Keystone authentication (up to version 3).

As Swift has a limit on the size of a single uploaded object (by default this is 5GB), the driver makes use of the Swift Large Object Support (http://docs.openstack.org/developer/swift/overview_large_objects.html). Only one container is used for both manifests and data objects. Manifests are stored in the 'files' pseudo directory, data objects are stored under 'segments'.

Types

type Driver

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

Driver is a storagedriver.StorageDriver implementation backed by Openstack Swift Objects are stored at absolute keys in the provided container.

func FromParameters

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

FromParameters constructs a new Driver with a given parameters map Required parameters: - username - password - authurl - container

func New

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

New constructs a new Driver with the given Openstack Swift credentials and container name
