我正在尝试使用声纳和postgres容器。下面是我的docker-compose文件
sonarqube:
image: sonar-master
ports:
- "9000:9000"
links:
- db:db
environment:
- SONARQUBE_JDBC_URL=jdbc:postgresql://db:5432/sonar
- SONARQUBE_JDBC_USERNAME=sonar
- SONARQUBE_JDBC_PASSWORD=sonar
db:
image: postgres:9.5.3
ports:
- "5432:5432"
environment:
- POSTGRES_USER=sonar
- POSTGRES_PASSWORD=sonar
当我尝试点击声纳网址时，我在浏览器中获得以下堆栈跟踪

似乎声纳无法连接到postgres。而且我无法在docker日志中找到任何细节。请帮我确定问题。
