在Docker中，我使用docker network create usta_network了一个新的networkingdocker network create usta_network命令，并在docker-compose.yml文件的服务声明中引用此networking。
没关系，我现在可以用容器的名字来ping服务，但是我怎么能在Nginx的上游声明中引用一个容器的名字呢？ 在集装箱之间进行访问是最好还是最好的做法？
docker.compose for nginx

用户nginx;
http { server { listen 80; index index.php index.html index.htm; server_name example.org www.example.org; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://rahmanusta_upstream; } } upstream rahmanusta_upstream { server rahmanusta_wp:6565; } }
docker-compose for mysql + wordpress

谢谢。
在你的docker-compose.yml中，你将用相关的名字命名每个服务。 假设我在我的名为jenkins1的nginx docker容器后面创建了一个jenkins实例。
在我的nginx.conf文件的http部分中，我命名上游服务器：
upstream jenkins { server jenkins1:8080; }
在服务器块，然后我可以调用这个如下;
location / { proxy_pass https://jenkins; }
这将引导所有的流量到达jenkins1服务容器上的端口8080，达到你的nginx容器端口。

在docker-compose.yml中，使用外部链接将.yml文件外部的两个容器链接起来。 您的nginx服务部分应该阅读;
services: nginx-main: image: nginx:latest ports: - "80:80" volumes: - ./nginx.conf:/etc/nginx/nginx.conf:ro - /var/log/nginx:/var/log/nginx external_links: - rahmanusta_wp - mysql_db container_name: nginx_main
