Types

type ProcessManager

type ProcessManager interface {
	KillRemoteEnforcer(contextID string, force bool) error
	LaunchRemoteEnforcer(contextID string, refPid int, refNsPath string, arg string, statssecret string, procMountPoint string) (bool, error)
}

ProcessManager interface exposes methods implemented by a processmon

func New

func New(ctx context.Context, p *env.RemoteParameters, c chan *policy.RuntimeError, r rpcwrapper.RPCClient) ProcessManager

New is a method to create a new remote process monitor.

type RemoteMonitor

type RemoteMonitor struct {

	// DisableLogWrite flag tells if we are running in kubernetes.
	DisableLogWrite bool

	sync.Mutex
	// contains filtered or unexported fields
}

RemoteMonitor is an instance of processMonitor

func (*RemoteMonitor) KillRemoteEnforcer

func (p *RemoteMonitor) KillRemoteEnforcer(contextID string, force bool) error

KillRemoteEnforcer sends a rpc to the process to exit failing which it will kill the process

func (*RemoteMonitor) LaunchRemoteEnforcer

func (p *RemoteMonitor) LaunchRemoteEnforcer(
	contextID string,
	refPid int,
	refNSPath string,
	arg string,
	statsServerSecret string,
	procMountPoint string,
) (bool, error)

LaunchRemoteEnforcer prepares the environment and launches the process. If the process is already launched, it will notify the caller, so that it can avoid any new initialization.
