[英]How to set host of service in Docker?
我正在嘗試在TeamCity
Docker代理上測試我的應用程序。 應用程序在gradle中運行內部docker。
這是我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
代理的輸出:

問題是圖像在172.19.0.xx3:5432上,但是到達了172.19.0.1:5432
我應該在docker-compose.yml
以便它可以獲取正確的主機?
在應用程序服務中,該服務與刪除主機聯系,放置遠程主機的名稱。 啟用這兩種服務,然后在控制台上運行docker ps
。 數據庫服務的名稱為somedirectory_db
。 將其作為連接字符串的一部分放在您的應用程序邏輯中; 例:
DSN=host:somdirectory_db;port=3306;schema=some_database
本質上,如果兩個服務都在同一網絡上,則可以將服務名稱用作可解析的DSN地址。
