JupyterHub + Docker派生程序

Question

我正在试着设置一个JupyterHub和一个码头产卵器。在我登录到我的JupyterHub后，我得到了以下错误：

500 : Internal Server Error
Error in Authenticator.pre_spawn_start: ChunkedEncodingError ('Connection broken: IncompleteRead(0 bytes read)', IncompleteRead(0 bytes read))
You can try restarting your server from the home page.

我的JupyterHub配置如下所示：

from jupyterhub.auth import Authenticator

class DictionaryAuthenticator(Authenticator):

    passwords = {'max':'123'}
        
    async def authenticate(self, handler, data):
        if self.passwords.get(data['username']) == data['password']:
            return data['username']


# docker image tag in the docker registry
c.DockerSpawner.image = 'jupyterhub/singleuser:latest' 

 # listen on all interfaces
c.DockerSpawner.host_ip = "0.0.0.0"

c.DockerSpawner.network_name = 'jupyterhub'
c.JupyterHub.spawner_class = 'dockerspawner.DockerSpawner'
c.JupyterHub.authenticator_class = DictionaryAuthenticator

下面是我的Dockerfile的内容：

FROM python:3.7
RUN pip3 install \
    jupyterhub==1.0.0 \
    'notebook>=5.0,<=6.0'

# create a user, since we don't want to run as root
RUN useradd -m max
ENV HOME=/home/max
WORKDIR $HOME
USER max


CMD ["jupyterhub-singleuser"]

如何修复此错误？

提前感谢您的帮助！

我能够解决这个问题。在我的例子中，Docker-Spawner只适用于docker版本2.3.0.5 (MacOS)。

如果有人遇到同样的问题-->只需降级即可。
