var RunningInUserNS = userns.RunningInUserNS

RunningInUserNS detects whether we are currently running in a user namespace. Deprecated: use github.com/containerd/containerd/pkg/userns.RunningInUserNS instead.

Functions ¶

func AdjustOOMScore ¶

func AdjustOOMScore(pid, score int) error

AdjustOOMScore sets the oom score for the provided pid. If the provided score is out of range (-1000 - 1000), it is clipped to the min/max value.

Not implemented on Windows

func CreateUnixSocket ¶

func CreateUnixSocket(path string) (net.Listener, error)

CreateUnixSocket creates a unix socket and returns the listener

func ForceRemoveAll ¶

func ForceRemoveAll(path string) error

ForceRemoveAll on unix is just a wrapper for os.RemoveAll

func GetLocalListener ¶

func GetLocalListener(path string, uid, gid int) (net.Listener, error)

GetLocalListener returns a listener out of a unix socket.

func GetOOMScoreAdj ¶

func GetOOMScoreAdj(pid int) (int, error)

GetOOMScoreAdj gets the oom score for a process

Not implemented on Windows

func GetOpenFds ¶

func GetOpenFds(pid int) (int, error)

GetOpenFds returns the number of open fds for the process provided by pid

func MkdirAllWithACL ¶

func MkdirAllWithACL(path string, perm os.FileMode) error

MkdirAllWithACL is a wrapper for os.MkdirAll on Unix systems.

func SetOOMScore ¶

func SetOOMScore(pid, score int) error

SetOOMScore sets the oom score for the process

Not implemented on Windows
