解 dokcer nodejs "ENOENT: no such file or directory, uv_cwd" issue.

可能是docker 內部的神奇部份，
所以只要 node app.js 跟 node ./app.js or node ../app/app.js
每個docker node 錯開　啟使，就正常了

aws multi docker 心得

每次重啟，每一個docker container 的資料會清空，記得要加上volume到外部的folder，才能保存資料。

Dockerrun.aws.json 的 environment 的設定方式

multi docker nginx + nodejs 心得

1. 用nginx prxoy 可以mapping到不同的image，但外部可以持續用相同的cookie . 
2. 多專案debug時，直接用內網ip做 proxy_pass就可以了
3. 用docker-compose做 multi docker，做link後，所有的port都不需要開到外部去，增加安全性.

	listen 80;

docker nginx 連外面的localhost port

 proxy_pass          http://192.168.1.108:3000/;
直接mapping 內網ip

run-dev.sh要改屬性，才能執行

chmod +x run.sh
