EnsureImage builds the layer image if not present (or if force is true). Returns the tag to run.

func ImageExists

func ImageExists(tag string) bool

ImageExists returns true if the local docker daemon has the given tag.

func NeedsBuild

func NeedsBuild(p config.Preset) bool

NeedsBuild reports whether the preset declares any layer.

func PrintBuild

PrintBuild emits what EnsureImage would do without running it.

func Tag

func Tag(name string, p config.Preset) string

Tag computes the deterministic local image tag for a preset.
