내장된 H2 대신 사용자 정의 mysql 데이터베이스를 사용하는 Keycloak 인스턴스를 시작하려고 합니다.
나는 docker를 사용할 계획이므로 mysql과 통신하기 위해 Keyclock docker용 네트워크를 만들었습니다.
도커 네트워크는 keycloak-network를 생성합니다.
다음 명령으로 mysql의 docker 인스턴스가 시작됩니다.
sudo docker run --name mysql-container--net keycloak-네트워크-v /home/renju/opt/EXONERATE/DB/mysql-data-5-7:/var/lib/mysql -e MYSQL_DATABASE=keycloak -e MYSQL_USER=ku -e MYSQL_PASSWORD=kupw -e MYSQL_ROOT_PASSWORD=myrootpw -d - p 3306:3306 mysql:5.7
keycloak이 데이터베이스에 액세스할 것으로 예상됩니다.열쇠망토사용자 이름 포함구그리고 비밀번호쿠푸. mysql에서 데이터베이스와 사용자가 생성되었는지 확인했습니다.

실패 원인을 알 수 없습니다. 내 우분투 컴퓨터에서 그것을 Tring하고 있습니다.
이 질문을 게시하기에 적합한 장소인지 확실하지 않습니다. stackoverflow 회원의 요청에 따라 그렇게 합니다.
답변1
에 따르면https://github.com/keycloak/keycloak-containers/blob/master/docker-compose-examples/keycloak-mysql.yml, 환경 변수 &connectTimeout=30000에 추가하기만 하면 됩니다 JDBC_PARAMS.
답변2
모닝 커피가 더 필요할 수도 있지만, 제가 보기에는 MySQL ku 사용자에게 권한이 부여되지 않은 것 같아서 애플리케이션도 실패합니다.
