Overview ¶
Package processmon is to manage and monitor remote enforcers. When we access the processmanager interface through here it acts as a singleton The ProcessMonitor interface is not a singleton and can be used to monitor a list of processes

Types ¶
type ExitStatus ¶
type ExitStatus struct {
// contains filtered or unexported fields
}
ExitStatus captures the exit status of a process The contextID is optional and is primarily used by remote enforcer processes and represents the namespace in which the process was running
type ProcessManager ¶
type ProcessManager interface { GetExitStatus(contextID string) bool SetExitStatus(contextID string, status bool) error KillProcess(contextID string) LaunchProcess(contextID string, refPid int, refNsPath string, rpchdl rpcwrapper.RPCClient, arg string, statssecret string, procMountPoint string) error SetnsNetPath(netpath string) }
ProcessManager interface exposes methods required by a processmonitor
func GetProcessManagerHdl ¶
func GetProcessManagerHdl() ProcessManager
GetProcessManagerHdl will ensure that we return an existing handle if one has been created. or return a new one if there is none
func NewTestProcessMon ¶
func NewTestProcessMon() ProcessManager
NewTestProcessMon creates a mock process manager
type ProcessMon ¶
type ProcessMon struct {
// contains filtered or unexported fields
}
ProcessMon exported
func (*ProcessMon) GetExitStatus ¶
func (p *ProcessMon) GetExitStatus(contextID string) bool
GetExitStatus reports if the process is marked for deletion or deleted
func (*ProcessMon) KillProcess ¶
func (p *ProcessMon) KillProcess(contextID string)
KillProcess sends a rpc to the process to exit failing which it will kill the process
func (*ProcessMon) LaunchProcess ¶
func (p *ProcessMon) LaunchProcess(contextID string, refPid int, refNSPath string, rpchdl rpcwrapper.RPCClient, arg string, statsServerSecret string, procMountPoint string) error
LaunchProcess prepares the environment for the new process and launches the process
func (*ProcessMon) SetExitStatus ¶
func (p *ProcessMon) SetExitStatus(contextID string, status bool) error
SetExitStatus marks the process for deletion
func (*ProcessMon) SetnsNetPath ¶
func (p *ProcessMon) SetnsNetPath(netpath string)
SetnsNetPath -- only planned consumer is unit test Call this function if you expect network namespace links to be created in a separate path
type TestProcessManager ¶
type TestProcessManager interface { ProcessManager MockGetExitStatus(t *testing.T, impl func(string) bool) MockKillProcess(t *testing.T, impl func(string)) MockLaunchProcess(t *testing.T, impl func(string, int, string, rpcwrapper.RPCClient, string, string, string) error) MockSetExitStatus(t *testing.T, impl func(string, bool) error) MockSetnsNetPath(t *testing.T, impl func(string)) }
TestProcessManager is a mock process manager
