Types

type ClusterRegistry added in v0.8.2

type ClusterRegistry interface {
	LatestDaemonVersion() (*semver.Version, error)

	// EngineVersion returns the current version of the cluster. If the
	// cluster does not yet have a version, zero will be returned. If
	// any error occurs, an error object will be returned. In this case,
	// the returned version number should be ignored.
	EngineVersion() (int, error)

	// UpdateEngineVersion attempts to compare-and-swap the cluster version
	// from one value to another. Any failures in this process will be
	// indicated by the returned error object. A nil value will be returned
	// on success.
	UpdateEngineVersion(from, to int) error
}
