如何在Docker中设置主机服务？
我试图在TeamCity docker agent上testing我的应用程序。 应用程序在gradle中运行内部泊坞窗。
这是我docker-compose.yml ：
version: '3' services: db: image: docker.int.address.com/postgres:9.6 ports: - 5432:5432 volumes: - ./init.sql:/docker-entrypoint-initdb.d/ environment: POSTGRES_PASSWORD: postgres POSTGRES_USER: postgres networks: my_net: ipv4_address: 172.19.0.3 networks: my_net: ipam: driver: default config: - subnet: 172.19.0.0/24
代理的输出：

问题是图像是在172.19.0.xx3：5432，但它达到了172.19.0.1:5432
我应该在docker-compose.yml写什么，这样才能得到正确的主机？
在应用程序服务中，在其到达除去主机的位置，放置远程主机的名称。 调出这两个服务，在控制台上运行docker ps 。 数据库服务将具有somedirectory_db的名称。 把它作为连接string的一部分放在你的应用程序逻辑中; 例：
DSN=host:somdirectory_db;port=3306;schema=some_database
实质上，如果两个服务在同一个networking上，则可以使用服务名称作为可parsing的DSN地址。
