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'.

type Driver

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

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

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

type Parameters

Parameters A struct that encapsulates all of the driver parameters after all values have been set
