我查看了与这些问题here,here,here和here相关的SO帖子,但是我对所建议的修复程序没有任何运气。每当我运行命令docker-compose -f stack.yml up
时,我都会收到以下堆栈跟踪:

我以为我的.yml文件非常简单,但是对于两个容器之间的内部路由失败,我必须缺少一些重要的内容。

我的stack.yml在下面:
version: '3'
services:
db:
image: postgres
restart: always
container_name: db
environment:
POSTGRES_USER: root
POSTGRES_PASSWORD: password
POSTGRES_DB: weg
ports:
- "5432:5432"
weg-api:
image: weg-api
restart: always
container_name: weg-api
ports:
- "8080:8080"
depends_on:
- "db"

我的Springboot应用程序属性如下:
spring.datasource.url=jdbc:postgresql://db:5432/weg
spring.datasource.username=root
spring.datasource.password=password
spring.jpa.generate-ddl=true
我不知道该如何进行。
答案 0 :(得分:3)
您的数据库正在db
容器上运行,而不是在localhost
容器内的weg-api
上运行。因此,您必须更改
spring.datasource.url=jdbc:postgresql://localhost:5432/weg
到
spring.datasource.url=jdbc:postgresql://db:5432/weg
我还建议您将container_name
赋予每个容器,以确保容器名称始终相同。否则,有时您可能会因配置而获得不同的名称。
version: '3'
services:
db:
image: postgres
restart: always
container_name: db
environment:
POSTGRES_USER: root
POSTGRES_PASSWORD: password
POSTGRES_DB: weg
ports:
- "5432:5432"
weg-api:
image: weg-api
restart: always
container_name: weg-api
ports:
- "8080:8080"
depends_on:
- "db"
