type App

type App struct {
	Image       string                // the image reference as supplied by the user on the cli
	ImType      AppImageType          // the type of the image reference (to be guessed, url, path or hash)
	Args        []string              // any arguments the user supplied for this app
	Asc         string                // signature file override for image verification (if fetching occurs)
	Exec        string                // exec override for image
	Mounts      []schema.Mount        // mounts for this app (superseding any mounts in rktApps.mounts of same MountPoint)
	MemoryLimit *types.ResourceMemory // memory isolator override
	CPULimit    *types.ResourceCPU    // cpu isolator override

	// TODO(jonboulle): These images are partially-populated hashes, this should be clarified.
	ImageID types.Hash // resolved image identifier
}

type AppImageType added in v0.14.0

type AppImageType int

AppImageType describes a type of an image reference. The reference can either be guessed or be a hash, a URL, a path, or a name. The first option means that the application will have to deduce the actual type (one of the last four).

const (
	AppImageGuess AppImageType = iota // image type to be guessed
	AppImageHash                      // image hash
	AppImageURL                       // image URL with a scheme
	AppImagePath                      // absolute or relative path
	AppImageName                      // image name
)

type Apps

type Apps struct {
	Mounts  []schema.Mount // global mounts applied to all apps
	Volumes []types.Volume // volumes available to all apps
	// contains filtered or unexported fields
