### Docker 테스트

cd /home
git clone https://github.com/sanggi-wjg/flask-jwt-demo.git

cd /flask-jwt-demo
docker build -t flask-jwt .
#docker run -d -p 8085:8085 --name flask-jwt flask-jwt

jenkins nexus docker hub credential 추가

배포 결과

Jenkins pipeline

production, alpha 등 환경에서는 소스 커밋이나 머지시에 한개 파이프라인에서 빌드해서
nexus에 push 하고 다른 파이프라인에서는 nexus에서 pull 받아서 배포하고 그런식으로 하면 될듯?
