   1. 설정값을 어떻게 불러올까?

   • 후보
     • pydantic패키지 BaseSettings모듈을 이용(환경변수)
     • yaml파일을 수동으로 로드

   설정값은 pydantic패키지 BaseSettings모듈을 이용

   패키지 설치

   pip install pydantic python-dotenv

   env파일 생성

   • env파일은 설정 값을 관리
   • ENV_STATE는 런타임 모드
   • prefix에 런타임모드 설정(DEV, PROD)

   ENV_STATE="dev" # or prod
   
   DEV_REDIS_HOST="127.0.0.1"
   DEV_REDIS_PORT="4000"
   
   PROD_REDIS_HOST="127.0.0.2"
   PROD_REDIS_PORT="5000"

   설정값 로드

   • .env파일에서 env_state값으로 런타임모드 확인

   class FactoryConfig:
         """Returns a config instance depending on the ENV_STATE variable."""
         def __init__(self, env_state: Optional[str]):
             self.env_state = env_state
   
         def __call__(self):
             if self.env_state == "dev":
                 return DevConfig()
   
             elif self.env_state == "prod":
                 return ProdConfig()
   
             elif self.env_state == "stage"
                 return StageConfig()

   설정은 어떻게?

   • 공통으로 사용하는 변수는 GlobalConfig에 설정
   • 각 런타임모드는 Globalconfig를 상속해서 구현하고, env_prefix를 사용해서 설정 값 로드

   class GlobalConfig(BaseSettings):
       """Global configurations."""
       # define global variables with the Field class
       ENV_STATE: Optional[str] = Field(None, env="ENV_STATE")
   
       # environment specific variables do not need the Field class
       REDIS_HOST: Optional[str] = None
       REDIS_PORT: Optional[int] = None
       REDIS_PASS: Optional[str] = None
   
       class Config:
           """Loads the dotenv file."""
           env_file: str = ".env"
   
   
   class DevConfig(GlobalConfig):
       """Development configurations."""
       class Config:
           env_prefix: str = "DEV_"
   
   
   class ProdConfig(GlobalConfig):
       """Production configurations."""
       class Config:
           env_prefix: str = "PROD_"
