遏制shinyproxy非常慢

Question

我使用堆栈部署了一个shinyapps：R，docker和shinyproxy，到目前为止，这些工具对用户来说非常棒。 但是我在负载平衡方面遇到了一些困难，因此当我在解决方案上运行更新时，我可以扩展并停止打扰用户。

根据https://www.shinyproxy.io/shinyproxy-containers/的建议，我使用了https://github.com/openanalytics/shinyproxy-config-examples/tree/master/02-containerized-docker - 发动机集装箱码头发动机。 当我运行java -jar shinyproxy-2.0.3.jar而不是容器化时，我的解决方案运行得很好。 但是现在当我将它集装箱化时，它变得非常非常缓慢，事实上，即使内部网络处于活动状态，当我尝试打开容器时，容器会崩溃。

目前我只是试图测试容器化shinyproxy是否可以工作而不会给我带来问题但是失败了。

我在服务器上的Nginx配置

server {

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name qnumsolutions.com www.qnumsolutions.com;

        location / { 
       proxy_pass          http://127.0.0.1:8080/;

       proxy_http_version 1.1;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "upgrade";
       proxy_read_timeout 600s;

       proxy_redirect    off;
       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_set_header  X-Forwarded-Protocol $scheme;
        }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/qnumsolutions.com/fullchain.pem; # managed by Certbot

}

Dockerfile

FROM openjdk:8-jre

RUN mkdir -p /opt/shinyproxy/
RUN wget https://www.shinyproxy.io/downloads/shinyproxy-2.0.3.jar -O /opt/shinyproxy/shinyproxy.jar
COPY application.yml /opt/shinyproxy/application.yml

WORKDIR /opt/shinyproxy/
CMD ["java", "-jar", "/opt/shinyproxy/shinyproxy.jar"]

最后sudo docker ps产量

非常感谢您的协助。

您的usage-stats-url似乎存在问题。 也许防火墙或某些东西阻止ShinyProxy到达这个目的地？ 我可以重现这种缓慢的行为，但当我评论这一行时它就消失了。

除此之外，你的application.yml有一些关于Docker的错误。 我改变了一点，并设法在我的本地机器上使用这种配置运行它（ nginx.conf和Dockerfile只是略微改变以适应我对docker docker-compose需求）：

我使用docker-compose运行所有内容，请参阅：

version: "3.1"

services:
  web:
    image: nginx:alpine
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./nginx.conf:/etc/nginx/conf.d/default.conf


  shinyproxy:
    image: sp_test
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./application.yml:/opt/shinyproxy/application.yml
