Constants

const (
	// Version (integer) represents the worker version.
	// Increased each time the engine changes.
	Version = 2
)

Variables

var (

	// ErrUnsupported is the error that should be raised when an OS or package
	// manager is not supported.
	ErrUnsupported = cerrors.NewBadRequestError("worker: OS and/or package manager are not supported")

	// ErrParentUnknown is the error that should be raised when a parent layer
	// has yet to be processed for the current layer.
	ErrParentUnknown = cerrors.NewBadRequestError("worker: parent layer is unknown, it must be processed first")
)

Functions

func Process

func Process(datastore database.Datastore, imageFormat, name, parentName, path string, headers map[string]string) error

Process detects the Namespace of a layer, the features it adds/removes, and then stores everything in the database. TODO(Quentin-M): We could have a goroutine that looks for layers that have been analyzed with an older engine version and that processes them.
