type StreamConfig 

type StreamConfig struct {
	// contains filtered or unexported fields
}

StreamConfig holds information about I/O streams managed together.

streamConfig.StdinPipe returns a WriteCloser which can be used to feed data to the standard input of the streamConfig's active process. streamConfig.StdoutPipe and streamConfig.StderrPipe each return a ReadCloser which can be used to retrieve the standard output (and error) generated by the container's active process. The output (and error) are actually copied and delivered to all StdoutPipe and StderrPipe consumers, using a kind of "broadcaster".
