Functions

func BinPath

func BinPath() (string, error)

BinPath returns the real path to self, resolving symbolink links. This is done to make the process name appears as 'runsc', instead of 'exe'.

func Capabilities

func Capabilities(specCaps *specs.LinuxCapabilities) (*auth.TaskCapabilities, error)

Capabilities takes in spec and returns a TaskCapabilities corresponding to the spec.

func GetExecutablePath

func GetExecutablePath(exec, root string, env []string) (string, error)

GetExecutablePath returns the absolute path to the executable, relative to the root. It searches the environment PATH for the first file that exists with the given name.

func Is9PMount

func Is9PMount(m specs.Mount) bool

Is9PMount returns true if the given mount can be mounted as an external gofer.

func LogSpec

func LogSpec(spec *specs.Spec)

LogSpec logs the spec in a human-friendly way.

func ReadSpec

func ReadSpec(bundleDir string) (*specs.Spec, error)

ReadSpec reads an OCI runtime spec from the given bundle directory.

TODO: This should validate the spec.
