Golang ExtractNames Examples

Example #1

File: list.go Project: rackeric/erack

	// assign vars from cli args
	user := c.String("user")

		APIKey:   key,

	// step 2, rax auth to get back provider instance
	provider, err := rackspace.AuthenticatedClient(ao)

	// set rax region
	serviceClient, err := rackspace.NewObjectStorageV1(provider, gophercloud.EndpointOpts{

	}

	// _, err := containers.Get(serviceClient, "{containerName}").ExtractMetadata()
