我想将我的服务部署到docker。
而我的服务是使用python + django和django-channels开发的

MyProject的/泊坞窗，compose.yml：

FROM nginx COPY service.conf /etc/nginx/sites-enabled/
的myproject / nginx的/ service.conf
server { listen 80; server_name example.com #i just want to hide domain name.. charset utf-8; client_max_body_size 20M; location /static/ { alias /opt/myproject/collected_static/; } location / { proxy_pass http://0.0.0.0:8000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; } }
我写了一个命令docker-compose up -d ，Nginx和达芙妮工作良好。
但是当我连接到example.com:80，我只能看到nginx的默认页面。
当我连接到example.com:8000时，我只能看到我的项目的服务页面。 （但不能看到静态文件）
我想链接nginx和daphne服务！ 我该怎么办？ 请帮帮我。
你错误地配置了NGINX。 试试proxy_pass http://127.0.0.1:8000;
至于静态文件，这是因为你还没有使容器可用的文件。 我会建议进行以下修改：
MyProject的/ Dockerfile：
[...] ADD . /opt/myproject VOLUME ["/opt/myproject/collected_static"] [..] # may I also suggest automatic static file collection? RUN python manage.py collectstatic --noinput
MyProject的/泊坞窗，compose.yml：
[...] build: ./nginx volumes_from: - "worker" # or daphne
我也会考虑添加image选项，以达芙妮和工人服务。 这将标记图像，并允许重复使用它，因此它将只被建立一次（而不是两次）。
myproject: build: . image: "myproject:latest" [..] worker: image: "myproject:latest" [..] daphne: image: "myproject:latest"
Nginx配置不正确，但是你的docker-compose需要一些修正：
Nginx网站提供了一些Docker部署的有用提示，你应该阅读，包括一个简单的Dockerfile示例：
FROM nginx RUN rm /etc/nginx/conf.d/default.conf RUN rm /etc/nginx/conf.d/example_ssl.conf COPY content /usr/share/nginx/html COPY conf /etc/nginx
这指向您需要做的一些改进（请参阅Docker Compose部分以获得有关Docker的进一步帮助）。
考虑到我们将在下面进行部署的更新，您还需要更改您的Nginx配置：
service.conf – > service.template listen ${NGINX_PORT}; server_name ${NGINX_HOST}; proxy_pass http://${DAPHNE_HOST}:${DAPHNE_PORT}; 现在你的Nginx配置是正确的，你需要正确设置docker compose指令，谢天谢地， Docker Hub Nginx页面有一个docker compose的例子：
这里是一个使用docker-compose.yml的例子：
web: image: nginx volumes: - ./mysite.template:/etc/nginx/conf.d/mysite.template ports: - "8080:80" environment: - NGINX_HOST=foobar.com - NGINX_PORT=80 command: /bin/bash -c "envsubst < /etc/nginx/conf.d/mysite.template > /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'"然后mysite.template文件可能包含这样的变量引用：
listen ${NGINX_PORT};
您可以进行所有这些改进，实际上，在不共享卷的情况下，您的静态文件将无法正确提供。
最后，我们可以合并这三个改进，给我们以下的设置：
MyProject的/ Dockerfile：
FROM python ENV PYTHONUNBURRERED 1 RUN mkdir -p /opt/myproject WORKDIR /opt/myproject ADD . /opt/myproject RUN pip install -r requirements.txt RUN python manage.py migrate # Can this be done during build? ie no link to the DB? VOLUME ["/opt/myproject/collected_static"]
