Functions

func ParseMapping

func ParseMapping(spec string) (rspec.LinuxIDMapping, error)

ParseMapping takes a mapping string of the form "container:host[:size]" and returns the corresponding rspec.LinuxIDMapping. An error is returned if not enough fields are provided or are otherwise invalid. The default size is 1.

func ToContainer

func ToContainer(hostID int, idMap []rspec.LinuxIDMapping) (int, error)

ToContainer takes an unmapped host ID and translates it to a remapped container ID using the provided ID mapping. If no mapping is provided, then the mapping is a no-op. If there is no mapping for the given ID an error is returned.

func ToHost

func ToHost(contID int, idMap []rspec.LinuxIDMapping) (int, error)

ToHost translates a remapped container ID to an unmapped host ID using the provided ID mapping. If no mapping is provided, then the mapping is a no-op. If there is no mapping for the given ID an error is returned.
