【问题描述】：

我有一个问题，有时docker-py 返回错误：

Permission denied.

我正在尝试修复它。我将这段代码注释掉，收到如下图。

File "/opt/dst/src/utils/runner.py", line 48, in run_code

\#if len(cli.containers(filters='status': ['running', 'created'])) >= settings.DOCKER_CONTAINER_COUNT:

Traceback (most recent call last):
  File "/opt/dst/env/lib/python2.7/site-packages/celery/app/trace.py", line 240, in trace_task
    R = retval = fun(*args, **kwargs)

    return self.run(*args, **kwargs)

    res = self._result(self._get(u, params=params), True)

    return f(self, *args, **kwargs)

    return self.get(url, **self._set_request_timeout(kwargs))
  File "/opt/dst/env/lib/python2.7/site-packages/requests/sessions.py", line 487, in get
    return self.request('GET', url, **kwargs)
  File "/opt/dst/env/lib/python2.7/site-packages/requests/sessions.py", line 475, in request
    resp = self.send(prep, **send_kwargs)
  File "/opt/dst/env/lib/python2.7/site-packages/requests/sessions.py", line 585, in send
    r = adapter.send(request, **kwargs)
  File "/opt/dst/env/lib/python2.7/site-packages/requests/adapters.py", line 453, in send
    raise ConnectionError(err, request=request)
ConnectionError: ('Connection aborted.', error(13, 'Permission denied'))

runner.pyc 文件已更新。 可能是什么问题呢？ 谢谢你的帮助，对不起我的英语不好

更新：

cli = Client('unix://var/run/docker.sock', version='1.19')
kill_client = Client('unix://var/run/docker.sock', version='1.19', timeout=0.5)
config = cli.create_host_config(**get_host_config(file_path))
#if len(cli.containers(filters='status': ['running', 'created'])) >= settings.DOCKER_CONTAINER_COUNT:
#    return 'must retry', None
run_string = 'timeout  python /tmp/script.py'.format(settings.DOCKER_EXECUTE_TIME)
container = cli.create_container('python:2', run_string, user=uid, host_config=config)

【问题讨论】：

如果删除注释掉的代码并运行它会发生什么，那么它可以正常工作吗？

请在您注释掉的那一行提供几行代码的代码块

从内存python 3这样解释cmets""" comment"""，单行注释就是你需要的#comment（你保存了吗？），你的jf条件是否超过80字符？尝试用 ` \ ` 将其分成两行，然后注释这两行

添加代码行围绕导致错误的块，否则我们都只会坐在这里猜测而无法来帮你。或者，请添加您的完整代码。

【参考方案1】：

由于脚本出错，工作了两个实例celery，在运行实例过程中出现了这个错误，谁用过旧代码。
