我的应用程序构建在RubyOnRails上,并使用乘客部署为弹性beanstalk应用程序,我正在尝试将标头添加到Nginx服务器并重新启动它,这是我的配置文件,来自aws弹性beanstalk的.ebextensions文件夹中的脚本：

packages: 
    yum:
        Nginx: [] 

files:
    "/etc/Nginx/conf.d/webapp.conf" :
        mode: "000644"
        owner: root
        group: root
        content: |
            server {

                location /assets {
                  alias /var/app/current/public/assets;
                  gzip_static on;
                  gzip on;
                  expires max;
                  add_header Cache-Control public;
                }

                location /public {
                  alias /var/app/current/public;
                  gzip_static on;
                  gzip on;
                  expires max;
                  add_header Cache-Control public;
                }

            }

# This reloads the server,which will both make the changes take affect and makes sure the config is valid when you deploy
container_commands:
  01_reload_Nginx:
    command: "sudo service Nginx reload"

但是我收到了这个错误：

[2017-12-13T06:23:48.635Z] ERROR [17344] : Command CMD-AppDeploy Failed!
[2017-12-13T06:23:48.635Z] INFO  [17344] : Command processor returning results:

/var/log/eb-activity.log：

虽然如果我ssh到实例并执行sudo服务Nginx重新加载它将正常执行..
任何的想法？

service Nginx configtest结果：

$sudo service Nginx configtest
Nginx: the configuration file /etc/Nginx/Nginx.conf Syntax is ok
Nginx: configuration file /etc/Nginx/Nginx.conf test is successful

您可能会遇到CDN服务到期的延迟,请尝试刷新缓存或直接对EB网址进行测试.

我想手动设置部署在AWS Elastic Beanstalk上的Docker容器的主机名.您可以在使用docker run -h HOSTNAME旋转容器时设置主机名,但我无法弄清楚如何(或者甚至是)将自定义参数传递给docker run命令.

Dockerrun.aws.json文件似乎是一个可能的候选者,但是没有记录的密钥能够满足我的需求.

有谁知道这是否可能？

这里可能的黑客攻击是利用EB对环境变量的不良解析.您可以设置环境变量,例如：
ParaM1 =哑-h MYHOSTNAME
EB不引用参数,因此您的-h部分将嵌入到docker run命令中.
我自己没试过.

另一个选择是创建一个ebextension文件来修补/opt/elasticbeanstalk/hooks/appdeploy/pre/04run.sh脚本,将-h MYHOST行注入其中.

Configuration > Software Configuration > Environment Properties

ConfigurationManager.AppSettings["MyServiceUrl"]
ConfigurationManager.AppSettings["aws:elasticbeanstalk:application:environment.MyServiceUrl"]
Environment.GetEnvironmentvariable("MyServiceUrl")
Environment.GetEnvironmentvariable("aws:elasticbeanstalk:application:environment.MyServiceUrl")

解决方法

option_settings:
  - option_name: MyServiceUrl
    value: change me

<appSettings>
  <add key="MyServiceUrl" value="change me" />
</appSettings>

string value = ConfigurationManager.AppSettings["MyServiceUrl"];

<appSettings>
  <add key="MyServiceUrl" xdt:Transform="Remove" xdt:Locator="Match(key)" />
</appSettings>
