我正在使用NodeJS + MongoDB
在本地Mac OS上测试docker-compose
,但是NodeJS
和MongoDB
无法成功连接。
如果我没有通过以下代码为--auth
设置MongoDB
,一切正常。
代码如下:
猫鼬连接
mongodb://mongodb:27017/myprojectdatabase
docker-compose.yml
version: "3"
services:
web:
build: .
restart: always
ports:
- "8080:8080"
depends_on:
- mongodb
volumes:
- .:/mycode
mongodb:
image: mongo:latest
ports:
- "27017:27017"
然后我想像下面那样为MongoDB启动--auth
,我遇到了错误。
docker-compose.yml
version: "3"
services:
web:
build: .
restart: always
ports:
- "8080:8080"
depends_on:
- mongodb
volumes:
- .:/mycode
# environment:
# - NODE_ENV=production
mongodb:
image: mongo:latest
command: [--auth]
environment:
MONGO_INITDB_ROOT_USERNAME: my_admin
MONGO_INITDB_ROOT_PASSWORD: my2019
MONGO_INITDB_DATABASE: myprojectdatabase
ports:
- "27017:27017"
volumes:
- ./mydata:/data/db
然后我跑
docker-compose down -v && docker-compose up --build
我得到了输出:

我是docker方面的新手。我想主要问题是web
无法与mongodb
建立连接。在这个问题上花费太长时间。
有帮助吗?谢谢!
答案 0 :(得分:1)
确保您不使用Web容器的本地主机。将容器视为单独的机器:一个容器中的localhost不与另一个容器共享。这就是为什么在连接字符串中有mongodb:27017
而不是localhost:27017
的原因,因为默认docker网络中的mongodb
是带有mongo的容器的DNS名称。在第一种情况(成功)中使用此连接字符串,请确保在第二种情况中使用有效的DNS名称。
还要确保在连接字符串中也包含您的数据库凭据(用户名:密码)。
