OpenStack Swift storage driver

An implementation of the storagedriver.StorageDriver interface that uses OpenStack Swift for object storage.

Parameters

Parameter	Required	Description
authurl	yes	URL for obtaining an auth token. https://storage.myprovider.com/v2.0 or https://storage.myprovider.com/v3/auth
username	yes	Your Openstack user name.
password	yes	Your Openstack password.
region	no	The Openstack region in which your container exists.
container	yes	The name of your Swift container where you wish to store the registry's data. The driver creates the named container during its initialization.
tenant	no	Your Openstack tenant name. You can either use tenant or tenantid.
tenantid	no	Your Openstack tenant id. You can either use tenant or tenantid.
domain	no	Your Openstack domain name for Identity v3 API. You can either use domain or domainid.
domainid	no	Your Openstack domain id for Identity v3 API. You can either use domain or domainid.
trustid	no	Your Openstack trust id for Identity v3 API.
insecureskipverify	no	true to skip TLS verification, false by default.
chunksize	no	Size of the data segments for the Swift Dynamic Large Objects. This value should be a number (defaults to 5M).
prefix	no	This is a prefix that will be applied to all Swift keys to allow you to segment data in your container if necessary. Defaults to the empty string which is the container's root.
secretkey	no	The secret key used to generate temporary URLs.
accesskey	no	The access key to generate temporary URLs. It is used by HP Cloud Object Storage in addition to the `secretkey` parameter.

authurl	URL for obtaining an auth token.
username	Your OpenStack user name.
password	Your OpenStack password.
container	The name of your Swift container where you wish to store the registry's data. The driver creates the named container during its initialization.
tenant	Optionally, your OpenStack tenant name. You can either use tenant or tenantid.
tenantid	Optionally, your OpenStack tenant id. You can either use tenant or tenantid.
domain	Optionally, your OpenStack domain name for Identity v3 API. You can either use domain or domainid.
domainid	Optionally, your OpenStack domain id for Identity v3 API. You can either use domain or domainid.
trustid	Optionally, your OpenStack trust id for Identity v3 API.
insecureskipverify	Optionally, set insecureskipverify to true to skip TLS verification for your OpenStack provider. The driver uses false by default.
region	Optionally, specify the OpenStack region name in which you would like to store objects (for example fr).
chunksize	Optionally, specify the segment size for Dynamic Large Objects uploads (performed by WriteStream) to Swift. The default is 5 MB. You might experience better performance for larger chunk sizes depending on the speed of your connection to Swift.
prefix	Optionally, supply a prefix that will be applied to all Swift keys to allow you to segment data in your container if necessary. Defaults to the empty string which is the container's root.
secretkey	Optionally, the secret key used to generate temporary URLs.
accesskey	Optionally, the access key to generate temporary URLs. It is used by HP Cloud Object Storage in addition to the `secretkey` parameter.

The features supported by the Swift server are queried by requesting the /info URL on the server. In case the administrator disabled that feature, the configuration file can specify the following optional parameters :

tempurlcontainerkey	Specify whether to use container secret key to generate temporary URL when set to true, or the account secret key otherwise.
tempurlmethods	Array of HTTP methods that are supported by the TempURL middleware of the Swift server. Example: - tempurlmethods: - GET - PUT - HEAD - POST - DELETE
