docker - Nginx没有Docker连接到Docker容器(clojure)

Question

我是webapps和nginx的新手。
我的default.conf看起来像这样

  listen 80;

  return 301 https://$host$request_uri;

}

server {
    server_name <my-domain-name>;

        location / {
            root /usr/share/nginx/html;
            index index.html;
        }

        location /static {
            root /usr/share/nginx/html;
        }

        location /api {
            proxy_pass http://<my-container-name>:8080/api;

            # tell http-kit to keep the connection
            proxy_http_version 1.1;

        proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-NginX-Proxy true;
            proxy_set_header X-Forwarded-Proto $scheme;

        proxy_set_header Host $host;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
        }


        listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live//fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live//privkey.pem; # managed by Certbot
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}


  server {
    if ($host = <my-domain>) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen              80;
    server_name <my-domain>;
    return 404; # managed by Certbot


}

我在一个 digital ocean ubuntu实例中运行nginx。我也有一个运行mye clojure http-kit webapp的docker容器。它正在侦听端口8080。它具有/ api / chsk / api / login / api / signup之类的路由。

我使用此脚本运行图像

#!/bin/sh
docker kill my-container
docker rm my-container
docker build -t my-image ~/my-project
docker run -p 8080:8080 --name my-container -d  my-image

这曾经可以工作，但是现在在运行systemctl start nginx时出现以下错误:

  Process: 16899 ExecStop=/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /run/nginx.pid (code=exited, status=0/SUCCESS)
  Process: 16505 ExecReload=/usr/sbin/nginx -g daemon on; master_process on; -s reload (code=exited, status=1/FAILURE)
  Process: 16850 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
  Process: 19501 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=1/FAILURE)

需要明确的是，我没有在docker中运行nginx。我同时提供静态内容。

它可以使用lein run在正确的端口上运行。感谢@ErwinRooijakkers。我将proxy_pass更改为localhost:8080 / api，它起作用了!谢谢。不确定为什么它不能与容器一起使用，因为它以前可以工作...
