docker - MySQL 컨테이너 실행
mysql도,
mysql - Docker Official Images
; https://hub.docker.com/_/mysql
"
SQL Server 2019"와 유사한 사용자 경험으로 컨테이너를 실행할 수 있습니다.
c:\temp> docker pull mysql
c:\temp> docker run --name mysql1 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=test_1234 -d mysql
마찬가지로 데이터베이스 변경에 대한 유지를 위해 볼륨 매핑을 추가할 수 있고,
c:\temp> docker run --name mysql1 -e MYSQL_ROOT_PASSWORD=test_1234 -v mysql:/var/lib/mysql -d mysql
(Docker Desktop의 경우 DockerDesktopVM의 공유된 볼륨 디렉터리는 "DockerDesktopVM의 파일 시스템 접근"을 참고)
DB 성격상 매번 자동으로 올라오게 설정할 것입니다.
c:\temp> docker run --name mysql1 -e MYSQL_ROOT_PASSWORD=test_1234 --restart=always -v mysql:/var/lib/mysql -d mysql
이후의 동작은 예전 글에 따라 동일하게 테스트할 수 있고,

공식 도구인 "MySQL Workbench"를 이용하는 것도 좋습니다.
