docker: Error response from daemon: Conflict. The container name "/mysql01" is already in use by container "646014e4386df9378362b32465d06baf8ff3dd0c79b32a4017c4d189ab7e3a88". You have to remove (or rename) that container to be able to reuse that name.

有可能自己的服务器mysql被占用3306所以选择随即动态端口
ps -ef|grep mysql
