var SupportedVolDrivers = map[string]struct{}{
	"vsphere": {},
	"local":   {},

Volume drivers currently supported. "local" is the default driver supplied by the client and is equivalent to "vsphere" for our implementation.

Functions

func ContainerInfoToDockerContainerInspect 

func ContainerInfoToDockerContainerInspect(vc *viccontainer.VicContainer, info *models.ContainerInfo, portlayerName string) (*types.ContainerJSON, error)

ContainerInfoToDockerContainerInspect takes a ContainerInfo swagger-based struct returned from VIC's port layer and creates an engine-api based container inspect struct. There maybe other asset gathering if ContainerInfo does not have all the information

func ContainerInfoToVicContainer 

func ContainerInfoToVicContainer(info models.ContainerInfo, portlayerName string) *viccontainer.VicContainer

func MountsFromContainer 

func MountsFromContainer(vc *viccontainer.VicContainer) []types.MountPoint

mountsFromContainer derives []types.MountPoint (used in inspect) from the cached container data.

func NewPortLayerClient 

func NewPortLayerClient(portLayerAddr string) *apiclient.PortLayer

func NewVolumeModel 

func NewVolumeModel(volume *models.VolumeResponse, labels map[string]string) *types.Volume

func RemoveAnonContainerVols 

func RemoveAnonContainerVols(ctx context.Context, pl *client.PortLayer, cID string, vc *viccontainer.VicContainer)

RemoveAnonContainerVols removes anonymous volumes joined to a container. It is invoked once the said container has been removed. It fetches a list of volumes that are joined to at least one other container, and calls the portlayer to remove this container's anonymous volumes if they are dangling. Errors, if any, are only logged.

Types

type AttachConfig 

type AttachConfig struct {
	*backend.ContainerAttachConfig

	// ID of the session
	ID string
	// Tells the attach copier that the stream's stdin is a TTY and to look for
	// escape sequences in stdin to detach from the stream.
	// When true the escape sequence is not passed to the underlying stream
	UseTty bool
	// CloseStdin signals that once done, stdin for the attached stream should be closed
	// For example, this would close the attached container's stdin.
