使用docker+nginx+django/angularjs提供静态文件时出现404

我遵循以下配置这存储库。我决定将我的 docker 配置和实际代码保存在单独的存储库中 - 我将使用 Dockerfile 克隆代码存储库。我正在使用 docker-machine（本地，使用 Virtualbox 驱动程序）和 docker-compose 设置。

代码仓库的目录结构大致如下：

|-- bower.json
|-- CONTRIBUTORS
|-- defsec
|   |-- defsec
|   |   |-- aws_settings.py
|   |   |-- heroku_settings.py
|   |   |-- __init__.py

该docker-compose.yml文件与我上面列出的存储库中的文件几乎相同，只有一点不同，那就是我将其挂载django到卷上.:/root- 如果没有它，[8] System error: no file or directory则会抛出错误。这可能是因为/usr/src/app在克隆之前不存在（供参考，这是原始文件）。Dockerfile（用于服务django）具有以下内容：

FROM ubuntu:14.04

ENV DJANGO_CONFIGURATION Docker

# First, we need to get git, and clone our repository
# Additionally, get everything else here too, such as nodejs and npm

RUN apt-get update
RUN apt-get install -y ca-certificates git-core ssh nodejs npm python-pip libpq-dev python-dev
RUN ln -s /usr/bin/nodejs /usr/bin/node

ENV HOME /root

# Add custom ssh keypair - usually Bitbucket deployment keys
ADD ssh/ /root/.ssh/

# Fix permissions
RUN chmod 600 /root/.ssh/*

# Avoid first connection host confirmation
RUN ssh-keyscan bitbucket.org > /root/.ssh/known_hosts

# Clone the repo
WORKDIR /usr/src/app
RUN git clone [email protected]:username/defsec-exam-app.git

# Install requirements
WORKDIR /usr/src/app/defsec-exam-app
RUN pip install -r requirements.txt
RUN npm install -g bower
RUN bower --allow-root install

# Remember to perform migrations on your own, and also create DB when needed.
# S3 Storage
...

# DB Settings
...

WORKDIR /usr/src/app/defsec-exam-app/defsec
CMD ["gunicorn", "defsec.wsgi", "-w", "2", "-b", "0.0.0.0:8000", "--log-level", "-"]

最后，nginx.conf提供静态文件的方法如下：

worker_processes 1;

events {

    worker_connections 1024;

}

http {

    server {
        listen 80;
        server_name example.org;

        access_log /dev/stdout;
        error_log /dev/stdout info;

        location /static/ {
            alias /usr/src/app/defsec-exam-app/static;
        }

        location /static/javascripts/ {
          default_type text/javascript;
          alias /usr/src/app/defsec-exam-app/static/javascripts/;
        }

        location /static/stylesheets/ {
          default_type text/css;
          alias /usr/src/app/defsec-exam-app/static/stylesheets/;
        }

    location /static/bower_components/ {
      alias /usr/src/app/defsec-exam-app/static/bower_components/;
    }

        location / {
            proxy_pass http://django:8000;
            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;
        }
    }
}

但是，我根本无法让 nginx 提供静态文件 - 它们都返回 404。我想知道nginx和django容器服务（如 中定义docker-compose.yml）之间的链接是否不正确，但似乎不是。我还检查了容器/etc/hosts中的文件nginx，因为链接会创建主机文件条目。

172.17.0.134    defsecdocker_django_1.bridge

我不确定这是否正确，因为只有 3 个容器，但 hosts 文件中却有大量条目，其中一些是重复的。这是可重现的行为 - 每次使用 docker-compose 构建和运行容器时，我都会得到这个确切的文件。docker-compose 日志可nginx确认 404。

任何指点都将不胜感激。

看起来 docker-compose 配置不正确。nginx 抛出这些 404 错误是因为它无法访问/usr/src/app/defsec-exam-app/static。

这是正确的 docker-compose 配置-：

# Nginx
nginx:
    build: ./nginx
    volumes_from:
        - django
    links:
        - django
    ports:
        - "80:80"

# This defines a service for the Django app
# Will include the Angular frontend
django:
    build: .
    volumes:
        - .:/root
        - /usr/src/app
    expose:
        - "8000"
    links:
        - postgres

# This defines a service for the Postgres database
postgres:
    image: postgres:latest

volumes_from从 django 服务获取卷。我已经将其公开usr/src/app为卷。这似乎很管用。如果有任何建议，我欢迎！

此外，这是新的 nginx 配置 -：

worker_processes 1;

events {

    worker_connections 1024;

}

http {

    server {
        listen 80;
        server_name example.org;

        access_log /dev/stdout;
        error_log /dev/stdout info;

        location /static/ {
            alias /usr/src/app/defsec-exam-app/static;
        }

        location /static/javascripts/ {
          default_type text/javascript;
          alias /usr/src/app/defsec-exam-app/static/javascripts/;
        }

        location /static/stylesheets/ {
          default_type text/css;
          alias /usr/src/app/defsec-exam-app/static/stylesheets/;
        }

    location /static/bower_components/ {
      types {
        text/css css;
        text/javascript js;
      }
      alias /usr/src/app/defsec-exam-app/static/bower_components/;
    }

    location /static/partials/ {
      types {
        text/html html;
      }
      alias /usr/src/app/defsec-exam-app/static/partials/;
    }

    location /static/admin/ {
          alias /usr/src/app/defsec-exam-app/static/admin/;
    }

    location /static/admin/css {
      default_type text/css;
      alias /usr/src/app/defsec-exam-app/static/admin/css;
    }

    location /static/admin/js {
      default_type text/javascript;
      alias /usr/src/app/defsec-exam-app/static/admin/js;
    }

    location /static/admin/img {
      types {
        image/png png;
        image/jpeg jpg;
      }
      alias /usr/src/app/defsec-exam-app/static/admin/img;
    }

        location / {
            proxy_pass http://django:8000;
            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;
        }
    }
}

注意：我必须将 django admin css/js/img 单独添加到 docker/deployment 存储库，以便 django admin 正常工作。（django Dockerfile 中的简单 ADD 命令即可解决问题）
