Functions

func Apply

func Apply(c *cgroups.Cgroup, pid int) (map[string]string, error)

func ApplyDevices

func ApplyDevices(c *cgroups.Cgroup, pid int) error

Symmetrical public function to update device based cgroups. Also available in the systemd implementation.

func Freeze

func Freeze(c *cgroups.Cgroup, state cgroups.FreezerState) error

Freeze toggles the container's freezer cgroup depending on the state provided

func GetPids

func GetPids(c *cgroups.Cgroup) ([]int, error)

func GetStats

func GetStats(systemPaths map[string]string) (*cgroups.Stats, error)

func NotifyOnOOM

func NotifyOnOOM(c *cgroups.Cgroup) (<-chan struct{}, error)

NotifyOnOOM sends signals on the returned channel when the cgroup reaches its memory limit. The channel is closed when the cgroup is removed.
