[ MySQL ] Docker MySQL 이미지 생성

테스트 DB를 구성하는데 있어 보다 편하게 하고싶어서 Docker 이미지를 생성하고 해당 이미지로 Container DB 생성을 해보았습니다.

이후에 해당 이미지를 이요하여 Container Replication을 구성해 볼 예정입니다.

[root@pmm-server ~]# docker ps 
CONTAINER ID   IMAGE                  COMMAND                CREATED          STATUS                       PORTS                                          NAMES

### Docker Image 테스트
[root@pmm-server ~]# docker run -it --name my -d leeyunhyeong/mysql8:1
[root@pmm-server ~]# docker ps
