在单个Docker容器环境中配置nginx（AWS ElasticBeanstalk）

Question

我目前正在使用AWS ElasticBeanstalk中的单个容器 docker 环境部署Django + uWSGI应用程序。这个环境已经随nginx一起提供了，我目前正在尝试配置它。

我正在努力实现以下目标：

1. 在环境的负载平衡器处终止HTTPS
2. 使用nginx（环境附带）将HTTP请求重定向到HTTPS
3. 将请求从Nginx传递给uwsgi

环境信息：

• 配置和解决方案堆栈名称：单一容器Docker 1.11版本2.3.0
• AMI：运行Docker 1.11.2 2016.09.0的64位Amazon Linux 2016.09 v2.3.0
• Docker版本：1.11.2
• 代理服务器：nginx 1.10.1

这是我当前的配置：

.ebxtensions / 00-负载平衡器终止https.config

option_settings:
  aws:elb:listener:443:
    ListenerEnabled: true
    ListenerProtocol: HTTPS
    SSLCertificateId: <resource-id-here>
    InstancePort: 443
    InstanceProtocol: HTTP
  aws:elb:listener:80:
    ListenerEnabled: true
    ListenerProtocol: HTTP
    InstancePort: 80
    InstanceProtocol: HTTP

.ebextensions / 01-nginx-proxy.config

files:
  "/etc/nginx/sites-available/test.domain.com.conf":
    mode: "000644"
    owner: root
    group: root
    content: |
      server {
        listen 80;
        server_name test.domain.com;
        access_log /var/log/nginx/$server_name.access.log;

        location / {
          return 301 https://$server_name$request_uri;
        }

        location = /status/ {
          access_log /var/log/nginx/$server_name.healthd.log healthd;
          include uwsgi_params;
          uwsgi_pass docker;
          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 $host;
          proxy_set_header X-Forwarded-Server $host;
        }

      }

      server {
        listen 443;
        server_name test.domain.com;
        access_log /var/log/nginx/$server_name.access.log;

        location / {
          include uwsgi_params;
          uwsgi_pass docker;
          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 $host;
          proxy_set_header X-Forwarded-Server $host;
          client_max_body_size 100m;
        }

        location /static {
            alias /var/www/static;
        }
      }

commands:
   00_enable_site:
    command: 'rm -f /etc/nginx/sites-enabled/* && ln -s /etc/nginx/sites-available/test.domain.com.conf /etc/nginx/sites-enabled/test.domain.com.conf'

.ebextensions / 02-healthcheckurl.config

option_settings:
  - namespace:  aws:elasticbeanstalk:application
    option_name:  Application Healthcheck URL
    value:  /status/

application.ini（uwsgi配置）

[uwsgi]
master = true
socket = :3031
processes = 4
enable-threads = true
threads = 2
chdir = /opt/app/
wsgi-file = test/wsgi.py
logto2 = /var/log/uwsgi.log
callable = application
py-autoreload = 3

现在，在测试配置时：

检查http://test.domain.com/status/工作正常

$ wget http://test.domain.com/status/
--2017-01-14 23:00:18--  http://test.domain.com/status/
Resolving test.domain.com... 52.xx.xx.xx, 52.xx.xx.xy
Connecting to test.domain.com|52.xx.xx.xx|:80... connected.
HTTP request sent, awaiting response... 200 OK

检查http://test.domain.com/hello/无法正常工作。它重定向很好，但是然后挂起，直到请求超时。

$ wget http://test.domain.com/hello/
--2017-01-14 22:59:13--  http://test.domain.com/hello/
Resolving test.domain.com... 52.xx.xx.xx, 52.xx.xx.xy
Connecting to test.domain.com|52.xx.xx.xx|:80... connected.
HTTP request sent, awaiting response... 301 Moved Permanently
Location: https://test.domain.com/hello/ [following]
--2017-01-14 22:59:15--  https://test.domain.com/hello/
Connecting to test.domain.com|52.xx.xx.xx|:443... connected.
HTTP request sent, awaiting response... 408 REQUEST_TIMEOUT
2017-01-14 23:00:17 ERROR 408: REQUEST_TIMEOUT.

按照@deviavir 的建议，我需要允许来自负载均衡器的流量进入 EC2 实例。

这是我的最终配置：
