package devices

import "github.com/opencontainers/runc/libcontainer/devices"

Package devices provides some helper functions for constructing device configurations for runc. These are exclusively used by higher-level runtimes that need to configure runc's device list based on existing devices.

Index ¶

• Variables
• func DeviceFromPath(path, permissions string) (*config.Device, error)
• func GetDevices(path string) ([]*config.Device, error)
• func HostDevices() ([]*config.Device, error)

Variables ¶

var ErrNotADevice = errors.New("not a device node")

ErrNotADevice denotes that a file is not a valid linux device.

Functions ¶

func DeviceFromPath ¶

func DeviceFromPath(path, permissions string) (*config.Device, error)

DeviceFromPath takes the path to a device and its cgroup_permissions (which cannot be easily queried) to look up the information about a linux device and returns that information as a Device struct.

func GetDevices ¶

func GetDevices(path string) ([]*config.Device, error)

GetDevices recursively traverses a directory specified by path and returns all devices found there.

func HostDevices ¶

func HostDevices() ([]*config.Device, error)

HostDevices returns all devices that can be found under /dev directory.
