How do you get exit code connect_get_namespaced_pod_exec ? #812
Description
Activity
@oz123 The error code arrives in the channel number 3 (error-channel) but it is not exposed by the stream() method.
As a workaround you can use:
from kubernetes.stream.ws_client import ERROR_CHANNEL .... client = stream(api.connect_get_namespaced_pod_exec, "myapp-78898448f4-pgnfl", "default", command=["false"], # <<< "false" returns with exit code = 1 stderr=True, stdin=False, stdout=True, tty=False, _preload_content=False) # <<< we need a client object client.run_forever(timeout=60) err = client.read_channel(ERROR_CHANNEL) pprint(yaml.load(err))and you should get
{'details': {'causes': [{'message': '1', 'reason': 'ExitCode'}]}, 'message': 'command terminated with non-zero exit code: Error executing in ' 'Docker Container: 1', 'metadata': {}, 'reason': 'NonZeroExitCode', 'status': 'Failure'}I'm going to add a method to get it in more convenient way.

When I run this as
resp = stream(v1.connect_get_namespaced_pod_exec, podName, namespace, command=exec_command, stderr=True, stdin=False, stdout=True, tty=False, _preload_content=preloadContent)
resp.run_forever(timeout=5)
print(resp.readline_channel(1))Response:
NoneHowever, print(resp.read_channel(1)) gives me proper output.
Any pointers why?
Currently I have to simply do this:
However, I can't get the error code, or the stderror.
Looking at the source code I don't see an easy way.
