Functions

func PKill

func PKill(name string, sig syscall.Signal) error

PKill finds process(es) using a regular expression and send a specified signal to each process.

func PidOf

func PidOf(name string) ([]int, error)

PidOf finds process(es) with a specified name (regexp match) and return their pid(s).

Types

type FakeProcFS

type FakeProcFS struct{}

func (*FakeProcFS) GetFullContainerName

func (fakePfs *FakeProcFS) GetFullContainerName(pid int) (string, error)

GetFullContainerName gets the container name given the root process id of the container. E.g. if the devices cgroup for the container is stored in /sys/fs/cgroup/devices/docker/nginx, return docker/nginx. Assumes that the process is part of exactly one cgroup hierarchy.

type ProcFS

type ProcFS struct{}

ProcFS provides a helper for getting container name via pid.

func (*ProcFS) GetFullContainerName

func (pfs *ProcFS) GetFullContainerName(pid int) (string, error)

GetFullContainerName gets the container name given the root process id of the container. E.g. if the devices cgroup for the container is stored in /sys/fs/cgroup/devices/docker/nginx, return docker/nginx. Assumes that the process is part of exactly one cgroup hierarchy.

type ProcFSInterface

type ProcFSInterface interface {
	// GetFullContainerName gets the container name given the root process id of the container.
	GetFullContainerName(pid int) (string, error)
}
