Interface ExecWatch

All Superinterfaces:

AutoCloseable, Closeable

public interface ExecWatch
extends Closeable

Method Summary

Modifier and Type	Method and Description
void	close() Gracefully close the Watch - the close message will not be sent until all pending messages have been sent.
CompletableFuture<Integer>	exitCode() Get a future that will be completed with the exit code.
InputStream	getError() Gets the InputStream for stdErr if TtyExecErrorable.redirectingError() has been called.
InputStream	getErrorChannel() Gets the InputStream associated with channel 3, which returns the final Status containing the exit code, which could indicate abnormal termination.
OutputStream	getInput() Gets the OutputStream for stdIn if ContainerResource.redirectingInput() has been called.
InputStream	getOutput() Gets the InputStream for stdOut if TtyExecOutputErrorable.redirectingOutput() has been called.
void	resize(int cols, int rows)

Method Detail

getInput

OutputStream getInput()

Gets the OutputStream for stdIn if ContainerResource.redirectingInput() has been called.

Closing this stream does not immediately force sending. You will typically call close() after you are finished writing - the close message will not be sent until all pending messages have been sent.

Returns:

the stdIn stream

getOutput

InputStream getOutput()

Gets the InputStream for stdOut if TtyExecOutputErrorable.redirectingOutput() has been called.

Returns:

the stdOut stream

getError

InputStream getError()

Gets the InputStream for stdErr if TtyExecErrorable.redirectingError() has been called.

Returns:

the stdErr stream

getErrorChannel

InputStream getErrorChannel()

Gets the InputStream associated with channel 3, which returns the final Status containing the exit code, which could indicate abnormal termination.

See also exitCode()

Returns:

the channel 3 stream

close

void close()

Gracefully close the Watch - the close message will not be sent until all pending messages have been sent.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

resize

void resize(int cols,
            int rows)

exitCode

CompletableFuture<Integer> exitCode()

Get a future that will be completed with the exit code.

Will be -1 if the exit code can't be determined from the status, or null if close is received before the exit code.
See https://github.com/kubernetes/kubernetes/issues/89899 - which explains there's currently no way to indicate end of input over a websocket, so you may not get an exit code when using stdIn.

Can be used as an alternative to ExecListener.onFailure(Throwable, io.fabric8.kubernetes.client.dsl.ExecListener.Response) and ExecListener.onExit(int, io.fabric8.kubernetes.api.model.Status) methods.

Returns:

the exit code future
