Functions

func BlockAccessToKernelFilesystems

func BlockAccessToKernelFilesystems(privileged, pidModeIsHost bool, mask, unmask []string, g *generate.Generator)

func CompleteSpec

func CompleteSpec(ctx context.Context, r *libpod.Runtime, s *specgen.SpecGenerator) ([]string, error)

Fill any missing parts of the spec generator (e.g. from the image). Returns a set of warnings or any fatal error that occurred.

func CreateExitCommandArgs

func CreateExitCommandArgs(storageConfig types.StoreOptions, config *config.Config, syslog, rm, exec bool) ([]string, error)

func DevicesFromPath

func DevicesFromPath(g *generate.Generator, devicePath string) error

DevicesFromPath computes a list of devices

func ExecuteCreate

func ExecuteCreate(ctx context.Context, rt *libpod.Runtime, runtimeSpec *spec.Spec, s *specgen.SpecGenerator, infra bool, options ...libpod.CtrCreateOption) (*libpod.Container, error)

func GenExposedPorts

func GenExposedPorts(exposedPorts map[string]struct{}) (map[uint16]string, error)

func GetDefaultNamespaceMode

func GetDefaultNamespaceMode(nsType string, cfg *config.Config, pod *libpod.Pod) (specgen.Namespace, error)

Get the default namespace mode for any given namespace type.

func GetNamespaceOptions

func GetNamespaceOptions(ns []string, netnsIsHost bool) ([]libpod.PodCreateOption, error)

GetNamespaceOptions transforms a slice of kernel namespaces into a slice of pod create options. Currently, not all kernel namespaces are supported, and they will be returned in an error

func InitFSMounts

func InitFSMounts(mounts []spec.Mount) error

func IsValidDeviceMode

func IsValidDeviceMode(mode string) bool

IsValidDeviceMode checks if the mode for device is valid or not. IsValid mode is a composition of r (read), w (write), and m (mknod).

func MakeContainer

func MakeContainer(ctx context.Context, rt *libpod.Runtime, s *specgen.SpecGenerator) (*spec.Spec, *specgen.SpecGenerator, []libpod.CtrCreateOption, error)

MakeContainer creates a container based on the SpecGenerator. Returns the created, container and any warnings resulting from creating the container, or an error.

func MakePod

func MakePod(p *entities.PodSpec, rt *libpod.Runtime) (*libpod.Pod, error)

func MapSpec

func MapSpec(p *specgen.PodSpecGenerator) (*specgen.SpecGenerator, error)

MapSpec modifies the already filled Infra specgenerator, replacing necessary values with those specified in pod creation

func ParseDevice

func ParseDevice(device string) (string, string, string, error)

ParseDevice parses device mapping string to a src, dest & permissions string

func ParsePortMapping

func ParsePortMapping(portMappings []types.PortMapping) ([]ocicni.PortMapping, map[string]map[string]map[uint16]uint16, map[string]map[string]map[uint16]uint16, error)

Parse port maps to OCICNI port mappings. Returns a set of OCICNI port mappings, and maps of utilized container and host ports.

func SpecGenToOCI

func SpecGenToOCI(ctx context.Context, s *specgen.SpecGenerator, rt *libpod.Runtime, rtc *config.Config, newImage *libimage.Image, mounts []spec.Mount, pod *libpod.Pod, finalCmd []string) (*spec.Spec, error)

SpecGenToOCI returns the base configuration for the container.

func SupersedeUserMounts

func SupersedeUserMounts(mounts []spec.Mount, configMount []spec.Mount) []spec.Mount

Supersede existing mounts in the spec with new, user-specified mounts. TODO: Should we unmount subtree mounts? E.g., if /tmp/ is mounted by one mount, and we already have /tmp/a and /tmp/b, should we remove the /tmp/a and /tmp/b mounts in favor of the more general /tmp?
