	ExitCode     *int
	OpenStdin    bool
	OpenStderr   bool
	OpenStdout   bool
	CanRemove    bool
	ContainerID  string

}

Config holds the configurations for execs. The Daemon keeps track of both running and finished execs so that they can be examined both during and after completion.

func NewConfig

func NewConfig() *Config

NewConfig initializes the a new exec configuration

func (*Config) CloseStreams

func (c *Config) CloseStreams() error

CloseStreams closes the stdio streams for the exec

func (*Config) InitializeStdio

func (c *Config) InitializeStdio(iop *libcontainerd.IOPipe) (containerd.IO, error)

InitializeStdio is called by libcontainerd to connect the stdio.

func (*Config) SetExitCode

func (c *Config) SetExitCode(code int)

SetExitCode sets the exec config's exit code

type Store

type Store struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

Store keeps track of the exec configurations.

func NewStore

func NewStore() *Store

NewStore initializes a new exec store.

func (*Store) Add

func (e *Store) Add(id string, Config *Config)

Add adds a new exec configuration to the store.

func (*Store) ByPid

func (e *Store) ByPid(pid int) *Config

ByPid returns an exec configuration by its pid.

func (*Store) Commands

func (e *Store) Commands() map[string]*Config

Commands returns the exec configurations in the store.

func (*Store) Delete

func (e *Store) Delete(id string, pid int)

Delete removes an exec configuration from the store.

func (*Store) Get

func (e *Store) Get(id string) *Config

Get returns an exec configuration by its id.

func (*Store) List

func (e *Store) List() []string

List returns the list of exec ids in the store.

func (*Store) SetPidUnlocked

func (e *Store) SetPidUnlocked(id string, pid int)

SetPidUnlocked adds an association between a Pid and a config, it does not synchronized with other operations.
