API 로컬 테스트를 할 수 있게 

로컬에서 구동시켜봤다.

>sam local start-api

설치 후 오랜만에 구동해보는 건지 구동이 안됐다.

pywintypes.error: (2, 'CreateFile', '지정된 파일을 찾을 수 없습니다.')

위와 같이 에러가 표시되며 실행이 안됐다.

왜 실행이 안되지 하며

다시 설치 과정을 다시 짚어보다가 도커 실치 과정을 봤다.

도커를 실행하고 나니 제대로
서비스가 올라갔다.

You can now browse to the above endpoints to invoke your functions. You do not 
need to restart/reload SAM CLI while working on your functions, changes will be reflected instantly/automatically. You only need to restart SAM CLI if you update your AWS SAM template

도커가 실행되지 않고 있어서 로컬 실행이 안되었던 것이다. 

서비스가 올라간 후 해당 서비스로 브라우저로 접속해보면
http://127.0.0.1:3000/hello
아래와 같이 도커 이미지를 마운트 하는 작업을 그때서야 시작하고 
도커에서 공유 폴더 수락하겠냐고 경고가 나오면 수락해줬다.

로컬에 도커 대시보드의 화면이다.

관련 도커 이미지가 올라와 있다.

기본 예제를 시행해서인지 생각보단 쉽다.

결과는 브라우저에 아래와 같이 잘 나왔다.

{"message":"hello world"}
