docker node项目 连接mongodb

在弄docker部署node项目的时候遇到了连接mongdb的问题，记录一下问题解决办法

一、Docker 安装 MongoDB

1.查找Docker Hub上的mongo镜像

[root@VM_49_93_centos mongo]# docker search mongo

2、拉取官方的镜像

docker pull mongo

3、运行容器

mkdir -p ~/mongo/db
cd ~/mongo
docker run -p 27018:27017 -v $PWD/db:/data/db -d --name mongodb mongo:latest

4、操作mongodb

docker exec -it ‘mongo CONTAINER ID’ bash
cd /bin
mongo

5、修改项目中连接mongodb (把mongodb连接地址localhost:27017更改为运行自己项目docker镜像时 --link指定另一个容器)

DB_URL = 'mongodb://admin:sunjianping@localhost:27017/changxiang';

DB_URL = 'mongodb://admin:sunjianping@mongodb/changxiang';

6、运行自己的node项目（myp 为自己项目的docker镜像 ）

docker run -i -t --name myp --link=mongodb:mongodb myp:1.2 /bin/bash
