AWS Elastic Beanstalk：nginx 重新加载失败

Question

我已经根据这篇文章向我的 Elastic Beanstalk 环境提供了 nginx 配置。我的应用程序位于 Docker 容器中。问题是环境重新加载nginx失败。

这是我的配置文件：

files:
  "/etc/nginx/conf.d/proxy.conf" :
    mode: "000644"
    owner: root
    group: root
    content: |
      client_max_body_size 500M;

container_commands:
  01_reload_nginx:
    command: "sudo service nginx reload"

这导致失败（之后/var/log/eb-activity.log）：

  Application deployment - Command CMD-Startup failed

当我删除部分时：

container_commands:
  01_reload_nginx:
    command: "sudo service nginx reload"

部署顺利。

有任何想法吗？我如何获得有关该命令究竟出了什么问题的信息？如果我 ssh 到我的实例，我可以毫无问题地执行命令。

Elastic beanstalk 部署过程将为您重新加载 nginx，因此您可以将其从脚本中永久删除并避免错误。弄清楚命令失败的确切原因只是学术性的
