从外部网络访问 Docker 上的 JupyterHub

Question

Docker对我来说是相当新的，我正在创建一个这样的jupyterhub容器

FROM ubuntu:18.04
LABEL maintainer="Jupyter Project <[e-mail]>"
# 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，基于此讨论

# 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，但我无法从外部访问它。如果我这样做：

my_ip:8000

我无法连接。

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

谢谢。

Answer 1

您可以在本地主机上配置 nginx，witch 将代理来自外部世界的端口请求，该端口将监听本地端口，并在您的 docker 容器中暴露

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

现在您可以从外部打开<your_ip>:7000

经过一段时间的挣扎，我根据这里的讨论和这里的文档找到了解决方案。我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;
}
}
