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 ConfigToSpec ¶

func ConfigToSpec(rt *libpod.Runtime, specg *specgen.SpecGenerator, contaierID string) (*libpod.Container, *libpod.InfraInherit, error)

ConfigToSpec takes a completed container config and converts it back into a specgenerator for purposes of cloning an existing container

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 ExtractCDIDevices ¶

func ExtractCDIDevices(s *specgen.SpecGenerator) []libpod.CtrCreateOption

ExtractCDIDevices process the list of Devices in the spec and determines if any of these are CDI devices. The CDI devices are added to the list of CtrCreateOptions. Note that this may modify the device list associated with the spec, which should then only contain non-CDI devices.

func FinishThrottleDevices ¶

func FinishThrottleDevices(s *specgen.SpecGenerator) error

FinishThrottleDevices takes the temporary representation of the throttle devices in the specgen and looks up the major and major minors. it then sets the throttle devices proper in the specgen

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 Inherit ¶

func Inherit(infra libpod.Container, s *specgen.SpecGenerator, rt *libpod.Runtime) (opts []libpod.CtrCreateOption, infraS *spec.Spec, compat *libpod.InfraInherit, err 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, clone bool, c *libpod.Container) (*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, exposePorts map[uint16][]string) ([]types.PortMapping, error)

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

func PullOrBuildInfraImage ¶

func PullOrBuildInfraImage(rt *libpod.Runtime, imageName string) (string, error)

PullOrBuildInfraImage pulls down the specified image or the one set in containers.conf. If none is set, it builds a local pause image.

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, compatibleOptions *libpod.InfraInherit) (*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?
