python kubernetes观看pod日志不起作用

Question

Trying to use the python kubernetes API to stream the output of kubernetes pod logs. (eventual goal is to stream the logs out via websocket)

Based off this PR that was merged into python kubernetes module, i thought watch would work with read_namespaced_pod_log?

v1 = client.CoreV1Api()
w = watch.Watch()
for e in w.stream(v1.read_namespaced_pod_log, name=pod, namespace=namespace, follow=True, tail_lines=1, limit_bytes=560, _preload_content=False):
   print(e)

But i get the error below, am i missing something that needs to be passed to watch? or read_namespaced_pod_log?

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.7/site-packages/kubernetes/watch/watch.py", line 132, in stream

You should just do:

v1 = client.CoreV1Api()
w = Watch()
for e in w.stream(v1.read_namespaced_pod_log, name=pod, namespace=namespace):
    print(e)
