Question

我将docker容器部署到Heroku主机。 Container包含nginx和静态文件，由webpack在contains-build阶段创建。根目录是/ data / www，包含index.html，style.css，style.css.map，bundle.js，vendor.bundle.js和带资源的目录（images / etc）

我的nginx conf：

worker_processes auto;

events {
    use epoll;
    multi_accept on;
}

http {
    access_log /dev/stdout;
    error_log /dev/stdout info;
    server {
        include listen.conf;

        types{
            text/javascript   js;
            text/css          css;
            image/jpeg        jpg;
            image/png         png;
        }
        default_type text/html;

        root /data/www;
        index /index.html;
        location / {
            try_files $uri $uri/ /index.html;
        }
    }
}

它在本地工作，但当我将图像推送到Heroku时：

docker build -t registry.heroku.com/tp-frontend-kv/web .
docker push registry.heroku.com/tp-frontend-kv/web

每个请求都返回500，nginx登录Heroku：

可能是什么问题？

PS dockerfile和其他人：github

在部署之前，请通过运行（需要heroku cli）来关注日志：

$ heroku logs --app <your-app> -t

您可能会看到导致500响应的nginx启动错误，例如，如果它尝试绑定到端口80（默认），您将看到：

nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)

密切关注这些错误，应提供一些见解。

Heroku + docker + nginx每个请求返回500
