Ruby on rails Rails应用程序在本地使用nginx，但在部署到EC2时重定向301

我有一个停靠的Rails应用程序，还有一个nginx容器，其中包含一些我已经设置好的运行时自定义配置。这个设置在我的本地机器上运行得非常好

我启动docker compose和指向应用程序网络的nginx容器，一切都像一个魔咒。我可以在localhost而不是localhost:8000上访问应用程序

但是，我目前正在AWS ECS上部署此功能，这里涉及一个带有HTTPS的负载平衡器

应用程序得到部署，两个容器都运行良好，但我点击的URL返回永久移动的301

这是我的default.conf

upstream PLACEHOLDER_BACKEND_NAME {
  server PLACEHOLDER_BACKEND_NAME:PLACEHOLDER_BACKEND_PORT;
}

server {
  listen 80;
  server_name www.PLACEHOLDER_VHOST;
  return 301 https://$host$request_uri;
}

server {
  listen 80 default deferred;
  server_name PLACEHOLDER_VHOST;

  root /PLACEHOLDER_BACKEND_NAME/public;

  # level due to Rail's asset pipeline.
  
  location ~ ^/assets/ {
    gzip_static on;

    expires max;
    add_header Cache-Control public;
    add_header Last-Modified "";
    add_header ETag "";
  }



  location ~ /\. {
    return 404;
    access_log off;
    log_not_found off;
  }

  try_files $uri $uri/index.html $uri.html @PLACEHOLDER_BACKEND_NAME;

  location = /favicon.ico {
    try_files /favicon.ico = 204;
    access_log off;
    log_not_found off;
  }


  add_header Strict-Transport-Security "max-age=31536000; includeSubDomains;";


  location @PLACEHOLDER_BACKEND_NAME {
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_redirect off;

    if ($http_x_forwarded_proto = "http") {
      return 301 https://$host$request_uri;
    }
    
    proxy_pass http://PLACEHOLDER_BACKEND_NAME;
  }
}

以下是我在容器启动时运行的脚本：

#!/usr/bin/env bash

set -e

PLACEHOLDER_BACKEND_NAME="my-api"
PLACEHOLDER_BACKEND_PORT="8000"


PLACEHOLDER_VHOST="$(curl http://169.254.169.254/latest/meta-data/public-hostname)"


DEFAULT_CONFIG_PATH="/etc/nginx/conf.d/default.conf"

sed -i "s/PLACEHOLDER_VHOST/${PLACEHOLDER_VHOST}/g" "${DEFAULT_CONFIG_PATH}"
sed -i "s/PLACEHOLDER_BACKEND_NAME/${PLACEHOLDER_BACKEND_NAME}/g" "${DEFAULT_CONFIG_PATH}"
sed -i "s/PLACEHOLDER_BACKEND_PORT/${PLACEHOLDER_BACKEND_PORT}/g" "${DEFAULT_CONFIG_PATH}"

# Execute the CMD from the Dockerfile and pass in all of its arguments.
exec "$@"

我甚至尝试将脚本中的占位符_VHOST设置为我的ELB公共DNS，但没有效果。这里可能有什么问题
