我在这里使用 postgresql image和 node official image和 我的docker-compose.yml文件看起来像 version: '2'services: postgres: restart: always image: sameersbn/postgresql:9.6-2 ports: - "5432:5432" environment: - DB_USER=shorturl
我的docker-compose.yml文件看起来像
version: '2'
services:
postgres:
restart: always
image: sameersbn/postgresql:9.6-2
ports:
- "5432:5432"
environment:
- DB_USER=shorturl
- DB_PASS=shorturl
- DB_NAME=shorturl
web:
build: .
ports:
- "4000:4000"
volumes:
- .:/shortlr
depends_on:
- postgres
command: ["./wait-for-it.sh","postgres:5432", "--", "npm", "start"]
当我运行docker-compose时,我的日志看起来像
