docker部署nodejs，mongodb

node项目启动方式
docker run --rm -itd -p 3000:3000 --name node_api -v "$(pwd)":/webapp/nodejs/node_api -w /webapp/nodejs/node_api  node npm start
将当前项目更目录挂载到容器/webapp/nodejs/node_api

docker run -d -p 27017:27017 -v "$(pwd)"/opt/mongodb/affiliate:/webapp/nodejs/node_api_db--name mongo

docker run -p 27017:27017 -v opt/mongodb/affiliate:/webapp/nodejs/node_api_db -d mongo
docker run -p 27017:27017 -v $PWD/opt/mongodb/affiliate:/webapp/nodejs/node_api_db -d mongo
docker run -p 27017:27017 -v $PWD:/webapp/nodejs/node_api_db --name mongo -d mongo --dbpath /opt/mongodb/affiliate
启动mongo的时候如果不指定数据存储路径，则默认在容器根目录下/data/db进行存储数据

管理mongodb

docker ps -a 查看所有的容器
docker ps 查看正在运行中的容器

root@ubuntu:/# docker ps

进入已经启动的容器

root@ubuntu:/# docker exec -it hungry_wright bash

然后可以在容器里使用mongodb shell 管理数据库
查看容器中，mongodb数据存在的目录
