도커를 이용하여 "MariaDB-10.4.15"를 운영 중이다가 오랜만에 "MariaDB-10.6.4"로 버전을 업그레이드 한 이후에, 로그에 다음과 같은 오류 기록이 남아 있었습니다.

기본적인 데이터베이스 동작에는 아무런 문제가 없었지만, 그래도 최초 실행될 때, "ERROR" 로그가 있는 것은 좀 껄끄러워 해결 방법을 찾아보니, 아주 간단한 문제였습니다.

 

하지만, 제 경우 Alpine 리눅스 기반으로 경량화한 컨테이너를 만들어서 사용하다 보니, mysqlcheck, mariadb-upgrade 등의 명령이 없어서 그 부분을 해결하느라 많은 시간을 소모했었습니다.

해결 방법

해결 방법은 간단합니다. 다음과 같이 "mariadb" 서비스 컨테이너 내부에 "mariadb-upgrade" 명령을 실행하여 데이터베이스 업그레이드를 수행합니다.

$ docker exec -it mariadb /bin/sh
$ /usr/bin/mariadb-upgrade

업그레이드가 완료된 이후에, "mariadb" 컨테이너를 중지하였다가 재시작하면, 관련 오류가 사라지고 정상적으로 MariaDB 서비스가 시작됩니다.
