結果發生忘了設定 IAM 權限，立馬添加 AWSElasticBeanstalkFullAccess 啦，再重新執行一次

以上就收工了 XD 在本機端的 project 裡頭，會有 .elasticbeanstalk 跟 .gitignore 的產生，接著再把一些 Dockerfile 與相關程式碼資料都搬進來吧，此例以架設 web server 為例
$ wget https://raw.githubusercontent.com/changyy/docker-study/web-server/Dockerfile
$ eb create dev-web
Creating application version archive "app-1507##_######".

如此一來，服務就跑起來了 :P 整個過程 AWS Elastic Beanstalk 使用了 S3 儲存開發環境、開了一台 EC2 機器、啟用一個 ELB 單位、添加兩個 cloudwatch 關注服務情況（開新機器或關機器）以及一個 Auto scaling group 來確保服務的不中斷。
如此一來，可以再用此指令開啟瀏覽位置
$ eb open
接著就會開啟 browser 瀏覽了，不需自行在找尋找位置。
另外，有興趣的可以用以下指令研究：
$ eb status

以上就差不多了，若有興趣的可以試一下另一個 dockfile: https://github.com/changyy/docker-study/tree/web-ssh-server，除了要下載 Dockfile 外，還要下載 start_service.sh ，其中後者可以參考 Docker 官方文件，改用 Supervisor 也行（https://docs.docker.com/articles/using_supervisord/）。機器開啟後，多了 ssh server 在執行。這時先去 EC2 查詢是哪一台機器，用 ssh ec2-user@server_ip 登入看看。
