Constants

const Name = "imgbuild"

Name of the engine

Types

type EngineConfig

type EngineConfig struct {
	types.Bundle
}

EngineConfig is the config for the Singularity engine used to run a minimal image during image build process

func (*EngineConfig) MarshalJSON

func (c *EngineConfig) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler interface

func (*EngineConfig) UnmarshalJSON

func (c *EngineConfig) UnmarshalJSON(b []byte) error

UnmarshalJSON implements json.Unmarshaler interface

type EngineOperations

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

EngineOperations implements the engines.EngineOperations interface for the image build process

func (*EngineOperations) CleanupContainer

func (e *EngineOperations) CleanupContainer() error

CleanupContainer _

func (*EngineOperations) Config

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

Config returns the EngineConfig

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 initializes engines config internals

func (*EngineOperations) MonitorContainer

func (e *EngineOperations) MonitorContainer(pid int) (syscall.WaitStatus, error)

MonitorContainer is responsible for waiting on container process

func (*EngineOperations) PrepareConfig

func (e *EngineOperations) PrepareConfig(masterConn net.Conn, wrapperConfig *wrapper.Config) error

PrepareConfig validates/prepares EngineConfig setup

func (*EngineOperations) StartProcess

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

StartProcess runs the %post script
