GitLab CI setting

gitlab CI 설정 중 대단히 하고 있던 착각들

• 모든 동작은 호스트에서 이루어진다 -> X

• 모든 동작은 Runner container 내부에서 이루어진다.

  그래서 모든 동작은 일회성으로 끝남.

  gradlew build 후 굳이 artifact로 넘겨주거나, "배포"한다고 해놓고 dockerhub에 push해놓고 끝나는 이유가 여기에 있었음.

  모든 동작은 runner container 내부에서 동작 후 해당 runner container는 죽기 때문에, 저장하는 등의 작업을 해봤자 다 사라진다.

• .gitlab-ci.yml file

    - deploy
