위에서 external_url 에 http://localhost:8082/gitlab 처럼 포트를 동일하게 드러내면 gitlab컨테이너 수행시 nginx 에서 8082포트를 열려다 already in use 에러를 맞게 된다. 이는 gitlab 구조상 제약으로 웹에 표출된 gitlab clone 주소는 localhost/gitlab으로 표기됨을 감안하고 진행한다.
Gitlab 초기 root 패스워드 확인

# WARNING: This password is only valid if ALL of the following are true:
# • You set it manually via the GITLAB_ROOT_PASSWORD environment variable

# • You set it BEFORE the initial database setup (typically during first installation)
# • You have NOT changed the password since then (via web UI or command line)
