circus web console 依赖tornado>3.2 无法访问的bug

circus web console 是一个很不错的web 监控circus 工具，但是对于高版本一直存在一个bug

信息如下

Traceback (most recent call last):

  File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 1369, in _stack_context_handle_exception

    raise_exc_info((type, value, traceback))

  File "/usr/local/lib/python2.7/dist-packages/tornado/stack_context.py", line 314, in wrapped

    ret = fn(*args, **kwargs)

  File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 1581, in future_complete

f.result()

  File "/usr/local/lib/python2.7/dist-packages/tornado/concurrent.py", line 215, in result

    raise_exc_info(self._exc_info)

  File "/usr/local/lib/python2.7/dist-packages/tornado/gen.py", line 230, in wrapper

    yielded = next(result)

  File "/usr/local/lib/python2.7/dist-packages/circusweb/circushttpd.py", line 164, in post

    endpoints = self.get_arguments('endpoint_list', [])

  File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 398, in get_arguments

    assert isinstance(strip, bool)

AssertionError

解决方法

使用固定版本tornado=3.2.2

对应dockerfile 的修改

FROM python:2.7-slim-stretch

LABEL AUTHOR="dalongrong"

LABEL EMAIL="1141591465@qq.com"

RUN apt-get update && apt-get install -y --reinstall build-essential 

    && pip install circus circus-web chaussette 

    && pip uninstall -y tornado 

    && pip install tornado==3.2.2 

    && apt-get remove -y --purge build-essential 

    && rm -rf /var/lib/apt/lists/*

使用

• 参考代码

说明

对应docker 镜像我也已经push docker hub 了，可以直接使用 dalongrong/circus:2.7-slim-stretch
