Types ¶
type Attach ¶
Attach allows callers to reattach to running tasks
There should only be one reader for a task's IO set because fifo's can only be read from one reader or the output will be sent only to the first reads
type Config ¶
type Config struct {
// Terminal is true if one has been allocated
Terminal bool
// Stdin path
Stdin string
// Stdout path
Stdout string
// Stderr path
Stderr string
}
Config holds the IO configurations.
type Creator ¶
Creator creates new IO sets for a task
func LogFile ¶
LogFile creates a file on disk that logs the task's STDOUT,STDERR. If the log file already exists, the logs will be appended to the file.
func NewCreator ¶
NewCreator returns an IO creator from the options
type DirectIO ¶
type DirectIO struct {
// contains filtered or unexported fields
}
DirectIO allows task IO to be handled externally by the caller
func NewDirectIO ¶
NewDirectIO returns an IO implementation that exposes the IO streams as io.ReadCloser and io.WriteCloser.
type FIFOSet ¶
type FIFOSet struct {
Config
// contains filtered or unexported fields
}
FIFOSet is a set of file paths to FIFOs for a task's standard IO streams
func NewFIFOSet ¶
NewFIFOSet returns a new FIFOSet from a Config and a close function
func NewFIFOSetInDir ¶
NewFIFOSetInDir returns a new FIFOSet with paths in a temporary directory under root
type IO ¶
type IO interface {
// Config returns the IO configuration.
Config() Config
// Cancel aborts all current io operations.
Cancel()
// Wait blocks until all io copy operations have completed.
Wait()
// Close cleans up all open io resources. Cancel() is always called before
// Close()
Close() error
}
IO holds the io information for a task or process
type Opt ¶
type Opt func(*Streams)
Opt customize options for creating a Creator or Attach
func WithFIFODir ¶
WithFIFODir sets the fifo directory. e.g. "/run/containerd/fifo", "/run/users/1001/containerd/fifo"
