环境:Nginx(带SSL)+Docker+Ghost

Docker容器运行时配置了环境变量-e URL=xxx

Nginx配置:

server {
    listen 443 ssl http2;
    ssl on;
    server_name xxxxx.xxx;
    ssl_certificate /etc/nginx/ssl/*.xxxxx.xxx.cer;
    ssl_certificate_key /etc/nginx/ssl/*.xxxxx.xxx.key;
    add_header Strict-Transport-Security max-age=31536000;
        location / {
        proxy_set_header    X-Real-IP   $remote_addr;
        proxy_set_header    Host              $http_host;
        proxy_pass         http://127.0.0.1:80xx;
}
}
server {
    listen 80;
    server_name xxxxx.xxx;
    add_header Strict-Transport-Security max-age=31536000;
    return 301 https://xxxxx.xxx$request_uri;
}

现象:Chrome提示重定向次数过多,关闭Docker容器显示502 Bad Gateway

不附加环境变量正常
