Functions

func DisplayJSONMessagesStream

func DisplayJSONMessagesStream(in io.Reader, out io.Writer, terminalFd uintptr, isTerminal bool, auxCallback func(JSONMessage)) error

DisplayJSONMessagesStream displays a json message stream from `in` to `out`, `isTerminal` describes if `out` is a terminal. If this is the case, it will print `\n` at the end of each line and move the cursor while displaying.

func DisplayJSONMessagesToStream

func DisplayJSONMessagesToStream(in io.Reader, stream stream, auxCallback func(JSONMessage)) error

DisplayJSONMessagesToStream prints json messages to the output stream

Types

type JSONError

type JSONError struct {
	Code    int    `json:"code,omitempty"`
	Message string `json:"message,omitempty"`
}

JSONError wraps a concrete Code and Message, `Code` is is an integer error code, `Message` is the error message.

func (*JSONError) Error

func (e *JSONError) Error() string

type JSONMessage

type JSONMessage struct {
	Stream          string        `json:"stream,omitempty"`
	Status          string        `json:"status,omitempty"`
	Progress        *JSONProgress `json:"progressDetail,omitempty"`
	ProgressMessage string        `json:"progress,omitempty"` // deprecated
	ID              string        `json:"id,omitempty"`
	From            string        `json:"from,omitempty"`
	Time            int64         `json:"time,omitempty"`
	TimeNano        int64         `json:"timeNano,omitempty"`
	Error           *JSONError    `json:"errorDetail,omitempty"`
	ErrorMessage    string        `json:"error,omitempty"` // deprecated
	// Aux contains out-of-band data, such as digests for push signing and image id after building.
	Aux *json.RawMessage `json:"aux,omitempty"`
}

JSONMessage defines a message struct. It describes the created time, where it from, status, ID of the message. It's used for docker events.

func (*JSONMessage) Display

func (jm *JSONMessage) Display(out io.Writer, isTerminal bool) error

Display displays the JSONMessage to `out`. If `isTerminal` is true, it will erase the entire current line when displaying the progressbar.

type JSONProgress

type JSONProgress struct {
	Current int64 `json:"current,omitempty"`
	Total   int64 `json:"total,omitempty"`
	Start   int64 `json:"start,omitempty"`
	// If true, don't show xB/yB
	HideCounts bool   `json:"hidecounts,omitempty"`
	Units      string `json:"units,omitempty"`
	// contains filtered or unexported fields
}

JSONProgress describes a Progress. terminalFd is the fd of the current terminal, Start is the initial value for the operation. Current is the current status and value of the progress made towards Total. Total is the end value describing when we made 100% progress for an operation.

func (*JSONProgress) String

func (p *JSONProgress) String() string
