amazon-web-services - 在单个 docker 容器环境中配置 nginx (AWS ElasticBeanstalk)

Question

我目前正在使用 single container docker environment 部署 Django + uWSGI 应用程序在 AWS ElasticBeanstalk 中。此环境已随 nginx 一起提供，我目前正在尝试对其进行配置。

我正在努力实现以下目标:

在环境的负载均衡器上终止 HTTPS

使用nginx(随环境提供)将HTTP 请求重定向到HTTPS

将请求从 nginx 传递到 uwsgi

环境信息:

配置和解决方案堆栈名称 : 单容器 Docker 1.11
版本 2.3.0

AMI : 64 位 Amazon Linux 2016.09 v2.3.0 运行 Docker
1.11.2
2016.09.0

Docker 版本 : 1.11.2

代理服务器 :nginx 1.10.1

这是我目前的配置:

.ebxtensions/00-loadbalancer-terminatehttps.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:

正在检查 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

正在检查 http://test.domain.com/hello/没有按预期工作。它重定向正常，但它会挂起，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

按照@deviavir 的建议，我需要允许从负载均衡器到 EC2 实例的流量。

这是我的最终配置:
