我有两个 Docker 容器，它们具有独立的应用程序前端和后端。

在第一个容器中，我已经构建了 ReactJS 代码和 nginx Web 服务器。这是 Dockerfile，

FROM nginx:1.15.2-alpine
COPY ./build /var/www
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 80
ENTRYPOINT ["nginx","-g","daemon off;"]

这是我的 nginx.conf 文件，

worker_processes 1;
events {
    worker_connections 1024;
}

http {
    server_tokens off;
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    upstream server {
        server 172.20.58.236:8080;
    }

    upstream client {
        server 172.19.59.36;
    }


    server {
        listen 80;

        root /var/www;
        index index.html index.htm;

        add_header 'Access-Control-Allow-Origin'  'http://172.19.59.36';
        add_header 'Access-Control-Allow_Credentials' 'true';
        add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
        add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';


        location /api {
            proxy_pass http://server;
        } …
