my-ghost로 시작하는 pod가 제대로 실행되지 않아 반복해서 재시동 되었지만 제대로 동작하지 않아 결국 실패했다.
Ghost update! 쉽게 될 리가 없지
pod 에서 발생하는 로그를 분석해서 ghost가 제대로 실행되지 않는 이유를 알아보기로 했다. Container의 로그를 인하기 위해 kubectl logs 명령어를 사용한다.
만일 pod에 여러 개의 container가 있는 경우 pod 명 뒤에 contaienr 명을 지정한다. 자세한 내용은 kubectl logs -h 로 확인해 본다.

[2019-11-05 13:42:03] WARN Ghost has shut down
[2019-11-05 13:42:03] WARN Your site is now offline
에러 로그를 보니 기존에 ghost 2.x에서 사용하던 theme simply 가 ghost 3.0과 호환이 되지 않아서 그런 듯 한다.
ghost theme 파일들은 PV(Persistent Volume)로 마운트 되는 디렉토리에 있는데 문제를 해결할 해결책을 생각해 보면
- theme simply를 수정해서 ghost 3.0과 호환되게 만든다.
- theme simpy 대신 ghost 3.0과 호횐되는 기본 casper 3.0 theme을 사용한다.
첫번째 옵션은 ghost theme에 대한 연구(?)가 필요해서 보다 쉬운 두 번째 방법으로 시도해 보기로 한다. ghost 3.0과 함께 발표된 기본 theme 인 casper 3.0을 사용하도록 변경하면 되는데 문제는 theme을 변경할 수 있는 화면도 ghost가 정상적으로 실행된 경우에 접근할 수 있는 설정 화면에 있다는 거.
그렇지만 아마도 ghost가 사용하는 theme 정보가 어딘가 파일에 저장되어 있을 듯 하니 그걸 변경하면 해결할 수 있을 듯 하다.
ghost.db 파일을 직접 수정해서 theme 변경
https://blog.tylerbuchea.com/customizing-ghost/ 그리고 https://www.ghostforbeginners.com/change-ghost-theme-from-command-line/ 를 본 ghost가 동작하는데 사용하는 설정 정보들이 ghost.db에 저장되어 있는 듯 하다. 그리고 sqlite로 저장된 이 파일을 직접 수정할 수 도 있는 듯.
PV로 마운트하는 ghost의 content/data 디렉토리에 있는 ghost.db 파일을 sqlite 툴로 열어본다. 설정에 관련된 내용은 settings 테이블에 저장된 듯 하다.

https://www.ghostforbeginners.com/change-ghost-theme-from-command-line/ 글을 참조하여 현재 사용하고 있는 theme을 가리키는 key인 activeTheme을 찾아보지만 2016 년 글이라 그런지 activeTheme이라는 key는 존재하지 않는다. DB scheme가 변경된 듯 하다. 하지만activeTheme이 아닌 유사한 이름인 active_theme 을 찾을 수 있다.
sqlite> SELECT * FROM settings where key = 'active_theme';

active_theme 키 값을 확인해 보니 문제가 되는 바로 그 simply임을 확인할 수 있다.
값 변경은 update 명령을 이용해서 변경할 수 있다. 역시 위 글 참조
sqlite> update settings set value='casper' where key = 'active_theme';
sqlite> SELECT * FROM settings where key = 'active_theme';

sqlite3 종료는 ctrl + d로.
이제 다시 pod의 상태를 확인해 보면 정상적으로 pod가 실행되고 있음을 확인할 수 있다.
$ kubectl get pods

웹 브라우저로 URL 접속하니 정상적으로 동작한다. 문제 해결…
