 # 백엔드
+fakebusters에서 제공하는 4가지 모델의 시연을 위한 데모페이지의 백엔드 코드
 
-`cd backend/dbust-backend-fastapi`
+fastapi, uvicorn 사용
 
-`pip install -r requirements.txt`
+### 최소 스펙
+v2 CPU, 16GB RAM (동영상 처리를 위함)
 
-`uvicorn main:app --reload`
+### 백엔드 실행
+1. config.py 설정
+- 각 모델 서버의 url 설정 필요
+- 각 모델 서버가 실행되고 있지 않으면, 프론트에 404 응답이 반한됨
+
+2. 실행 환경 설정
+프로젝트 전체 최상단 폴더에 위치한 setup.sh 로 backend conda 가상환경 실행이 필요함
+```bash
+conda activate backend
+```
+
+3. 백엔드 코드 실행
+```bash
+cd dbust-backend-fastapi
+uvicorn main:app --reload                       #localhost, 8000으로 실행
+uvicorn main:app --host 0.0.0.0 --port 8000     #호스트와 포트 지정해 실행
+```
