从外部网络访问 docker 上的 jupyterhub

Question

Docker 对我来说相当新，我正在创建一个类似的 jupyterhub 容器

FROM ubuntu:18.04
LABEL maintainer="Jupyter Project <jupyter@googlegroups.com>"

# install nodejs, utf8 locale, set CDN because default httpredir is unreliable
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get -y update && \
apt-get -y upgrade && \
apt-get -y install wget git bzip2 && \
apt-get purge && \
apt-get clean && \
rm -rf /var/lib/apt/lists/*
ENV LANG C.UTF-8

# install Python + NodeJS with conda
RUN wget -q https://repo.continuum.io/miniconda/Miniconda3-4.5.11-Linux-x86_64.sh -O /tmp/miniconda.sh  && \
echo 'e1045ee415162f944b6aebfe560b8fee */tmp/miniconda.sh' | md5sum -c - && \
bash /tmp/miniconda.sh -f -b -p /opt/conda && \
/opt/conda/bin/conda install --yes -c conda-forge \
  python=3.6 sqlalchemy tornado jinja2 traitlets requests pip pycurl \
  nodejs configurable-http-proxy && \
/opt/conda/bin/pip install --upgrade pip && \
rm /tmp/miniconda.sh
ENV PATH=/opt/conda/bin:$PATH

ADD . /src/jupyterhub
WORKDIR /src/jupyterhub

RUN npm install -g configurable-http-proxy
RUN python3 -m pip install jupyterhub
RUN python3 -m pip install dockerspawner 

WORKDIR /srv/jupyterhub/
EXPOSE 8000

COPY jupyterhub_config.py /srv/jupyterhub/jupyterhub_config.py

LABEL org.jupyter.service="jupyterhub"

CMD ["jupyterhub"]

使用以下配置文件，基于this discussion

# launch with docker
c.JupyterHub.spawner_class = 'dockerspawner.DockerSpawner'

# we need the hub to listen on all ips when it is in a container
c.JupyterHub.hub_ip = '0.0.0.0'
c.JupyterHub.port = 8000
c.DockerSpawner.extra_host_config = {'network_mode': 'host'}
c.DockerSpawner.use_internal_ip = True
c.DockerSpawner.network_name = 'host'

然后我做：

docker run -i -p 8000:8000 --name jupyterhub jupyterhub:latest jupyterhub -f jupyterhub_config.py

它在我的内部网络上按预期工作，但我无法在外部访问它。如果我这样做：

my_ip:8000

我无法连接。

对于我在 docker 上运行的 Flask 应用程序，我所做的只是在 0.0.0.0 ip 中运行该应用程序并且它可以工作，我对如何配置网络感到困惑。欢迎任何帮助。

谢谢。

根据here 的讨论和here 的文档，我在挣扎了一段时间后找到了解决方案。我的jupyterhub_config.py 变成了：

c.JupyterHub.bind_url = 'http://0.0.0.0:8000/jhub'

按照我提供的链接，/etc/nginx/sites-enabled/jupyterhub.conf 变成了

# top-level http config for websocket headers
# If Upgrade is defined, Connection = upgrade
# If Upgrade is empty, Connection = close
map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}

server {
  listen 80;
  listen [::]:80;

  server_name my_ip;

  location /jhub {
      rewrite /jhub/(.*) /jhub/$1 break;
      proxy_pass http://0.0.0.0:8000/;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      # websocket headers
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection $connection_upgrade;
  }
  location / {
      proxy_pass http://0.0.0.0:5000/;
  }

  location ~ /.well-known {
     allow all;
  }
}

您可以在 localhost 上配置 nginx，女巫将代理来自外部世界的端口请求，该端口将在您的 docker 容器中公开监听本地端口

server {

    server_name <your_ip>;
    location / {
        proxy_pass http://0.0.0.0:8000;
    }
    listen 7000; 
}

现在你可以从外部打开<your_ip>:7000
