storage provisioner가 구축된 상태가 전제이다.
내용을 모르겠다면 아래 포스팅을 참고하여 provisioner를 구축하고 진행해야한다.

volume 매핑은 위 참고 사이트에서보고 작성했다.

이후 접속했을 때 에러가 발생한다면 external url에 대해 gitlab쪽에 설정을 해야하는데 하지 않아서 발생하는 것이다.
provisioner의 data directory로 접속해서 gitlab.rb파일을 수정해준다.

[root@master01 default-gitlab-config-pvc-39ec7735-095b-49fc-a02b-249711974951]# vim gitlab.rb
[root@master01 default-gitlab-config-pvc-39ec7735-095b-49fc-a02b-249711974951]# pwd
/data/default-gitlab-config-pvc-39ec7735-095b-49fc-a02b-249711974951

# external_url 'GENERATED_EXTERNAL_URL'
external_url 'xxx.xxx.xxx.xxx:30315'

이후 재접속
