Types

type EngineOperations

type EngineOperations struct {
	CommonConfig *config.Common                  `json:"-"`
	EngineConfig *singularityConfig.EngineConfig `json:"engineConfig"`
}

EngineOperations describes a runtime engine

func (*EngineOperations) CleanupContainer

func (engine *EngineOperations) CleanupContainer(fatal error, status syscall.WaitStatus) error

CleanupContainer cleans up the container

func (*EngineOperations) Config

func (e *EngineOperations) Config() config.EngineConfig

Config returns a pointer to a singularity.EngineConfig literal as a config.EngineConfig interface. This pointer gets stored in the Engine.Common field.

func (*EngineOperations) CreateContainer

func (engine *EngineOperations) CreateContainer(pid int, rpcConn net.Conn) error

CreateContainer creates a container

func (*EngineOperations) InitConfig

func (e *EngineOperations) InitConfig(cfg *config.Common)

InitConfig stores the pointer to config.Common

func (*EngineOperations) MonitorContainer

func (engine *EngineOperations) MonitorContainer(pid int, signals chan os.Signal) (syscall.WaitStatus, error)

MonitorContainer monitors a container

func (*EngineOperations) PostStartProcess

func (engine *EngineOperations) PostStartProcess(pid int) error

PostStartProcess will execute code in master context after execution of container process, typically to write instance state/config files or execute post start OCI hook

func (*EngineOperations) PrepareConfig

func (e *EngineOperations) PrepareConfig(starterConfig *starter.Config) error

PrepareConfig checks and prepares the runtime engine config

func (*EngineOperations) StartProcess

func (engine *EngineOperations) StartProcess(masterConn net.Conn) error

StartProcess starts the process
