Types

type Manager 

type Manager interface {
	// Join adds the given PID to all available controllers of the cgroup
	Join(pid int) error
	// Read the given cgroup file data and returns the content as a string
	Read(controller, file string) (string, error)
	// ReadCPUSet returns defined CPUSet
	ReadCPUSet() (cpuset.CPUSet, error)
	// Write the given data to the given cgroup kind
	Write(controller, file, data string) error
	// IsCgroupV2 returns true if CGroups are using V2 implementation
	IsCgroupV2() bool
	// RelativePath returns the controller relative path
	RelativePath(controller string) string
}

Manager represents a cgroup manager able to join the given cgroup

func NewManager 

func NewManager(dryRun bool, pid uint32, cgroupMount string, log *zap.SugaredLogger) (Manager, error)

NewManager creates a new cgroup manager from the given cgroup root path

type ManagerMock 

type ManagerMock struct {
