示例1: GetPidsForContainer
// TODO: this can be improved with our driver
// there has to be a better way to do this
func (d *driver) GetPidsForContainer(id string) ([]int, error) {
pids := []int{}
subsystem := "devices"
cgroupRoot, err := cgroups.FindCgroupMountpoint(subsystem)
if err != nil {
return pids, err
}
cgroupDir, err := cgroups.GetThisCgroupDir(subsystem)
if err != nil {
return pids, err
}
filename := filepath.Join(cgroupRoot, cgroupDir, id, "tasks")
if _, err := os.Stat(filename); os.IsNotExist(err) {
filename = filepath.Join(cgroupRoot, cgroupDir, "docker", id, "tasks")
}
output, err := ioutil.ReadFile(filename)
if err != nil {
return pids, err
}
for _, p := range strings.Split(string(output), "\n") {
if len(p) == 0 {
continue
}
pid, err := strconv.Atoi(p)
if err != nil {
return pids, fmt.Errorf("Invalid pid '%s': %s", p, err)

func (d *driver) GetPidsForContainer(id string) ([]int, error) {
pids := []int{}
// memory is chosen randomly, any cgroup used by docker works
subsystem := "memory"
cgroupRoot, err := cgroups.FindCgroupMountpoint(subsystem)

return pids, err
}
cgroupDir, err := cgroups.GetThisCgroupDir(subsystem)

return pids, err
}
filename := filepath.Join(cgroupRoot, cgroupDir, id, "tasks")
if _, err := os.Stat(filename); os.IsNotExist(err) {
// With more recent lxc versions use, cgroup will be in lxc/
filename = filepath.Join(cgroupRoot, cgroupDir, "lxc", id, "tasks")
}
output, err := ioutil.ReadFile(filename)
if err != nil {
return pids, err
}
for _, p := range strings.Split(string(output), "\n") {
