Docker 4.12.0 on Windows throws "The pipe has been ended" error #3045
Description
Hi team,
We've started to see error messages with Docker Desktop v4.12.0 on Windows. We are attaching to the container by calling {container_instance}.attach(stream=True, logs=True, demux=True) and then iterating through the logs streams. This is working fine with earlier versions but it started to throw following error with Docker Desktop v4.12.0.
Traceback (most recent call last): File "c:\users\administrator\workplace\aws-sam-cli\samcli\local\docker\container.py", line 401, in _write_container_output for stdout_data, stderr_data in output_itr: File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\types\daemon.py", line 32, in __next__ return next(self._stream) File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\api\client.py", line 406, in <genexpr> gen = (demux_adaptor(*frame) for frame in gen) File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\utils\socket.py", line 94, in frames_iter_no_tty (stream, n) = next_frame_header(socket) File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\utils\socket.py", line 66, in next_frame_header data = read_exactly(socket, 8) File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\utils\socket.py", line 51, in read_exactly next_data = read(socket, n - len(data)) File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\utils\socket.py", line 35, in read return socket.recv(n) File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\transport\npipesocket.py", line 23, in wrapped return f(self, *args, **kwargs) File "c:\users\administrator\workplace\aws-sam-cli\venv\lib\site-packages\docker\transport\npipesocket.py", line 117, in recv err, data = win32file.ReadFile(self._handle, bufsize) pywintypes.error: (109, 'ReadFile', 'The pipe has been ended.') A simplified version of how we are reading the logs;
# stdout and stderr are StreamWriter's that is been provided earlier logs_itr = container.attach(stream=True, logs=True, demux=True) for stdout_data, stderr_data in output_itr: if stdout_data and stdout: stdout.write(stdout_data) if stderr_data and stderr: stderr.write(stderr_data) See related issue here: aws/aws-sam-cli#4222
Thanks!
