Types

type Cloud 

type Cloud interface {
	// GetPublicIPAddress returns the stringified address (e.g "1.2.3.4") of the runtime
	GetPublicIPAddress(name string, zone string) (string, error)

	// CreateInstance creates a virtual machine instance given a name and a zone.  Returns the
	// IP address of the instance.  Waits until Docker is up and functioning on the machine
	// before returning.
	CreateInstance(name string, zone string) (string, error)

	// DeleteInstance deletes a virtual machine instance, given the instance name and zone.
	DeleteInstance(name string, zone string) error

	// Open a secure tunnel (generally SSH) between the local host and a remote host.
	OpenSecureTunnel(name string, zone string, localPort int, remotePort int) (*os.Process, error)
}

The Cloud interface provides the contract that cloud providers should implement to enable running Docker containers in their cloud. TODO(bburns): Restructure this into Cloud, Instance and Tunnel interfaces
