Functions

func GetFakeContainerID

func GetFakeContainerID(name string) string

GetFakeContainerID generates a fake container id from container name with a hash.

func IsContainerNotFoundError

func IsContainerNotFoundError(err error) bool

IsContainerNotFoundError checks whether the error is container not found error.

func IsImageNotFoundError

func IsImageNotFoundError(err error) bool

IsImageNotFoundError checks whether the error is image not found error. This is exposed to share with dockershim.

func NewCalledDetail

func NewCalledDetail(name string, arguments []interface{}) calledDetail

Types

type FakeContainer

type FakeContainer struct {
	ID         string
	Name       string
	Running    bool
	ExitCode   int
	Pid        int
	CreatedAt  time.Time
	StartedAt  time.Time
	FinishedAt time.Time
	Config     *dockercontainer.Config
	HostConfig *dockercontainer.HostConfig
}

Because the new data type returned by engine-api is too complex to manually initialize, we need a fake container which is easier to initialize.

type FakeDockerClient

type FakeDockerClient struct {
	sync.Mutex
	Clock                clock.Clock
	RunningContainerList []dockertypes.Container
	ExitedContainerList  []dockertypes.Container
	ContainerMap         map[string]*dockertypes.ContainerJSON
	ImageInspects        map[string]*dockertypes.ImageInspect
	Images               []dockertypes.ImageSummary
	ImageIDsNeedingAuth  map[string]dockertypes.AuthConfig
	Errors               map[string]error

	EnableTrace   bool
	RandGenerator *rand.Rand

	// Created, Started, Stopped and Removed all contain container docker ID
	Created []string
	Started []string
	Stopped []string
	Removed []string
	// Images pulled by ref (name or ID).
	ImagesPulled []string

	VersionInfo dockertypes.Version
	Information dockertypes.Info
	ExecInspect *dockertypes.ContainerExecInspect

	EnableSleep     bool
	ImageHistoryMap map[string][]dockerimagetypes.HistoryResponseItem
	// contains filtered or unexported fields
}
